Tsunami Risk The district has experienced sixteen local confirmed Tsunami since 1832. Four of these

were regional from the islands. The two largest tsunami had heights of 10 metres and 5-6

metres respectively. These were generated on the Ariel Bank in 1947 approximately 70

kilometres off the coast.

A small earthquake preceded both of them with the waves impacting on the coast about

30 minutes later. Scientists have described the type of earthquake involved as a ‘long

duration’ earthquake as they release their energy over a longer period.

Two other smaller events have been recorded in Tolaga Bay in 1926 and 1970 with no

earthquake preceding them. These could have been caused either by an undersea

landslide or more likely an event associated with meteorological conditions.

The East Coast has experienced twelve confirmed distant Tsunami events since 1868. For

the distant events, five originated from South America, another from the Krakatoa

eruption, one from the Aleutian Islands and one from Indonesia. The largest rise in sea

level recorded from any of the distantly generated events has been between two and

four metres above normal high tide.

The Pacific Tsunami Warning Centre in Hawaii would provide sufficient warning (nine to

fourteen hours) for a distant tsunami that required evacuation.

The whole Gisborne District coastline is at risk from locally generated Tsunami.

The available information relating to distant events indicates that one of our vulnerable

assets that would be affected are our ships in the port. Those that are manoeuvring could

be capsized as the sea empties from the harbour and then surges back in and ships that

are tied up could be damaged as they surge up and down.

The logs in the lower log yard could also pose a risk depending upon the height of the

waves.

For distant Tsunami this should not be a problem as sufficient warning is given to allow

ships to put to sea and avoid the effects of the wave.

The most likely threat for distant events is from the west coast of South America. Peru is

seen as more significant than Chile as a source because of the way they propagate

across the Pacific.

Any Tsunami event has the potential to cause a bore (a wave up the rivers) and cause

considerable damage. None of the previous ‘observed’ events have caused the rivers to

overtop.

Considerable work has been done, and will continue to be done, to convince coastal

schools of the need to evacuate inland after a significant or long duration earthquake.


3

There is also a continued need to educate the public. One of the worst case scenarios

for a locally generated Tsunami will be to the camping population along the coast from

December through to January/February. The potential for a significant number of

casualties is real. This is likely when we remember that many on the coast never felt the

earthquake in 1947. The largest percentage of those injured will have trauma injuries,

which will severely test the health system. Outside assistance would most probably be

required.

Warnings The Ministry of Civil Defence & Emergency Management (MCDEM) is responsible for

receiving the information from the Pacific Tsunami Warning Centre and passing it to

Tairāwhiti Civil Defence Emergency Management (CDEM) for further action.

MCDEM receives PTWC information to New Zealand and assesses the risk before issuing an

Advisory or a Warning.

National Advisories

National Advisory - No Tsunami Threat to New Zealand

National Advisory - Large Pacific Earthquake Being Assessed (holding message)

This message will be sent for large Pacific Earthquakes (M7.5+)

National Warnings

National Warning - Tsunami Threat – Local Source

National Warning - Tsunami Threat to Beach and Marine Areas

National Warning - Tsunami Threat to Land and Marine Areas

Tsunami Cancellation Messages

National Warning - Tsunami Warning for New Zealand Cancelled

“A beach and marine threat” means the only threat is for those on the water and the

beaches and no evacuations are required.

MCDEM is responsible for alerting the national and international media.

On receipt of the national information, Tairāwhiti Civil Defence Emergency Management

is responsible for:

ensuring all key partners, area coordinators, GDC staff and the public are aware of

the threat

Emergency Mobile Alerts

The Emergency Mobile Alert (EMA) system delivers alerts directly to people’s mobile

phones in targeted areas without subscription required. MCDEM and CDEM Groups have

agreed the optimum arrangements to alert people. EMA must reach the following

criteria:


4

High priority alerts are for risks that:

• have occurred, are ongoing or where their probability of occurrence is greater than 50% • have a significant threat to life, health and property; and • where response actions should be taken immediately

NB: If the above criteria is not met, then do not send a mobile alert

More information on EMA can be found in the Tsunami Advisory Plan (MCDEM) and the appendix

Established Priorities and Strategies Established priorities during any Tsunami event will be:

The safety of people and protection of people through public education, timely

warnings and managed evacuations

The assessment of impacts and timely recovery

Unless the size of the Tsunami event dictates otherwise, general strategies for the

management of a confirmed event will be:

To evacuate people (for up to 24hrs after first impact in a distant event) in the "at

risk areas" shown on the maps or through education

Encourage self-evacuation for local events (for about 2 hours or unless told

otherwise)


5

Near Source Tsunami/Local Tsunami

Regional Tsunami

Distant Tsunami

The only warning the public will get will be a "LONG or STRONG duration earthquake" and a tsunami may arrive in as little as 10 minutes.

Agencies initial actions are to remain safe and protect assets from the earthquake. Those in potential impact areas may move resources to safe areas after the shaking stops.

Generated greater than nine hours away from areas such as Peru and Chile

Tsunami waves can be generated from other areas of New Zealand. The Kermadec Trench and the Islands may impact the East Coast in less than 3 hours

PLAN A - Near Source/Local

Tsunami Initial Response Plan


8

Introduction Aim

This Plan will outline the roles and activities required of Tairāwhiti (Gisborne) CDEM Group

and partner agencies during a local source tsunami event in order to save lives, and

ensure the ongoing health, safety and welfare of impacted people in accordance with

National Plans and messaging.

Intent

The intent is to save lives and ensure the health, safety, and welfare of evacuated people

by delivering a clear, coordinated and structured response to a local source tsunami

caused by an earthquake. This will be achieved by agencies taking responsibility and co-

ordinating their own initial response planning so that the initial response occurs

spontaneously within the guidance of this document.

In order to maintain public confidence in the Civil Defence response efforts, this Plan also

seeks to provide clear and consistent messaging both before and during an event. To

achieve this, public information and education will be consistent with National messaging

and will be centrally controlled by the Tairāwhiti (Gisborne) CDEM Group Public

Information Management (PIM) Team.

This Plan addresses the first 12 hours of a response after a tsunami event has struck the

Tairāwhiti Area. It sets the expectations of agencies prior to and during the first phase of

an event (Readiness and Initial Response).

Background

Strong/severe earthquakes centred off the East Coast could generate tsunami in the

Tairawhiti region in as little as ten minutes. The district has experienced twelve local

confirmed tsunami since 1832. Most of the tsunami were triggered by earthquakes

however two tsunami were generated in 1926 and 1970 when no earthquake was

recorded. These were thought to be generated by an underwater landslide or

meteorological conditions.

However following the magnitude 7.8 Kaikoura earthquake (Nov, 2016) GNS have issued a

series of scenarios regarding potential tsunami risk from the Hikurangi subduction zone.

The potential risk from this area could impact upon the Tairāwhiti (Gisborne) region and

require mass self-evacuation from pre-identified evacuation zones.


9

Ministry Civil Defence Emergency Management (MCDEM) Expectations When shaking is LONG or STRONG people living in the tsunami evacuation areas should

be moving inland or to higher ground. There may not be enough time to warn people, to

declare and to get people evacuated.

In areas where a local source earthquake was not felt as LONG or STRONG CDEM Groups

should decide and announce whether evacuations are appropriate themselves – based

on the earthquake parameters in Geonet and National Warning System Messages.

etc.

Know what supplies are required for 2-3 days

Response

Messaging is based around ‘look after yourselves, listen to the radio and do the following:’

Stay away from the Coast until the all clear is given by Tairāwhiti CDEM (this may be

via Community Link and Media)

Return home - if advised to do so by Tairāwhiti CDEM or your Area Community Link

Information from Tairāwhiti CDEM

Go to friends and families out of the evacuation zone (rely on road access)

Sit tight and look after yourselves (if able to do so)

If you have needs, go to your nearest Community Emergency Centre (front cover

of the yellow pages)

Methods to be utilised by Public Information Management (PIM) Readiness (Check boxes when completed)

Social Media (Facebook/Neighbourly) GDC Website

Print Media (local/national paper) Existing Phone Trees

Welfare Arrangements Mission To provide immediate welfare assistance to evacuees.

Welfare Response Objectives

1. Deploy rapid needs assessment teams to gathering points to:

Triage those with immediate needs

Conduct rapid registration to facilitate potential future welfare needs

First aid

Provide reassurance

Identify, support and supervise unaccompanied minors

Establish communications with ECC

Deliver essential goods/catering (as capacity allows)

These teams will be made up from CDEM Volunteers, Red Cross and the Salvation Army.

2. Establish centralised coordinated welfare response which provides for all Tairāwhiti’s

communities.

a) Activation of the Welfare Coordination Group and relevant sub functions

b) Coordination with the area welfare managers

c) Activation of central welfare function operating from the ECC which would be a

single welfare team for the region and would:

• Establish liaison with impacted communities

• Plan and coordinate initial welfare response

• Plan and coordinate rapid and ongoing needs assessment

• Plan for welfare delivery in response to identified needs

• Coordinate welfare planning across the welfare sub functions

• Coordinate delivery of welfare services

• Plan for and deliver emergency accommodation

• Plan for and deliver household goods and services

Considerations

Daytime (inside or outside of school hours)

Night time

Weekday versus weekend

Public Holidays

Weather and season

Public/Community/Sporting Events

Security of facilities/Safety of Staff


20

The Area Welfare Centre is situated at the Salvation Army’s Worship and Community

Centre 389 Gladstone Road, Gisborne

Community Emergency Centres

Immediate Actions of Volunteers:

Once your safety and that of your family is established, volunteers will do the following:

Those from both the rural and urban communities will gather at their identified

community emergency centres and support the needs of their local community.

CD Volunteers may be operating from Community Emergency Centres (Appendix 4) and

are unlikely to have adequate resources in place. They will need to be resourced by

CDEM as soon as they can.

The CECs have base radios to be able to communicate with the ECC.

Coordination & Deployment of Teams

1. Teams will be coordinated and tasked by the ECC; this will be effected via agency

liaison personnel either at the ECC or located on the ground

2. ECC will conduct a briefing outlining the situation, location and where to deploy;

3. ECC will provide registration/needs assessment forms and instructions

4. Teams will be configured to achieve an optimum mix of skills to be able to fulfil the

task eg: First aid, supervising unaccompanied minors, communications

Triage of Evacuees

Priority Need Action/s 1 Medical (physical & mental)

First Aid Transfer to medical facility

2 Unaccompanied Minor

Reunify with caregiver (as per guidelines) Supervision (by trained personnel or professional) Place in care of Police

3 Other urgent needs Provide support as resources allow

4 Wet/cold/not adequately clothed Provide support as resources allow

5 Any other needs prioritising families with infants, young children, the elderly, and those with disabilities

Provide support as resources allow


21

Welfare Planning Assessment Evacuation and Gathering Up to 4 hours 4 + hours

Assumptions People will either:

• self-evacuate on long or

strong earthquakes

• evacuate on advisory

from family/friends/word

of mouth

• evacuate on receiving

public alert

• be unable or unwilling to

evacuate

People will go to:

• friends and family

• nearby high ground

• known gathering points*

• places in town eg.

supermarket car parks

Evacuees will fend for

themselves or be

supported by

friends/family or the wider

community (community

led response)

Radio messaging will be

important to advise any of

the following:

• Return home (if

advised to do so)

• Go to friends and

family out of the

evacuation zone (rely

on road access)

• Sit tight or look after

yourselves (if able to

do so)

• If you have needs

come to an identified

gathering point

If all clear isn’t given

people will be tired,

hungry and

anxious/frustrated/upset

Will have basic needs

that need to be met:

food, warmth,

sanitation

People with ill health,

medical conditions, the

elderly and very young

will be more vulnerable

Tourists with no local

connections or

resources could be

22

Transition to Planned Welfare Response

As coordination and situational awareness is established, the Welfare Function at the ECC

in conjunction with the Incident Management Team will plan beyond the initial response.

In the event of actual tsunami and/or earthquake damage the plan will likely consider:

Formalised registration and needs assessment

Delivery of welfare services across the welfare sub functions including animal

welfare

Household Goods & Services

Shelter & Accommodation

Psychosocial Support

Care & Protection Services for Children & Young People

Financial Assistance

Inquiry

PLAN B: Regional and Distant

Tsunami Response Plan


24

Notification For a regional and distant Tsunami, warnings and updates are passed directly to Ministry

of Civil Defence & Emergency Management (MCDEM) in Wellington to CDEM Groups, the

Police Communication Centres and the Media.

The times of impact and expected wave height are also stated on the warnings and

whether it is a ‘beach and Marine threat’ or ‘full inundation’ expected.

CDEM staff can also monitor the Pacific DART buoy, Tsunami warning centre, International

media and the NZ tidal buoys.

Release of information within the Gisborne District is via a holding statement to the Media

and through Facebook until further information is available which will then be passed on

through media releases, emails and Facebook posts.

activate their personnel to start evacuating the tsunami inundation areas

Immediately contact the Incident Management Team (IMT) by text and request

their attendance at the CDEM Office

Notify Chief Executive and Leadership Team

Ensure Port Eastland is aware of tsunami warning

Notify GDC Staff, CD Tsunami Text and CD Warnings and Tsunami email list and let

approved messages and tell people to stay put, and listen to the radio for further

information

If required, contact the Mayor, Deputy Mayor or Chairperson who can declare an

emergency and ask them to attend the CDEM Office

An immediate decision will need to be made on whether to declare and confirm

the areas to be evacuated. This decision will be influenced by the time available

and the direction the wave is coming from

The Police will need to play a major role in the evacuation of the designated areas

to ensure the message is enforced with the public in the at risk areas

Establish Emergency Coordination Centre (CDEM Office or at EIT or new GDC

Council Building)

Declaration

If it becomes apparent that a distantly generated Tsunami is going to impact on our coast

and the information indicates that large scale evacuation is necessary, then a

declaration of state of local emergency needs to be made to make sure people are

evacuating.

Public Notification

This will be through CD community link structure, radio, emails, texts, Facebook, GDC

websites asking people to leave the inundation areas.


26

Evacuation

If the IMT decides that evacuation of the tsunami inundation area is required then Civil

Defence Volunteers, Police and FENZ will have a major role in getting people evacuated.

Step 2 (more than three hours) - Distant Tsunami

Contact the coastal Area Co-ordinators and the Community Emergency Managers

(Awapuni, Wainui, Muriwai, Whangara) and update them on what has happened

including times, threat location and that more information will be available after

emergency and ask them to attend the CDEM Office.

An immediate decision will need to be made on whether to declare and confirm

the areas to be evacuated. This decision will be influenced by the time available

and the direction the wave is coming from.

Establish Emergency Coordination Centre (CDEM Office or at EIT or new GDC

Council Building).


27

Declaration

If it becomes apparent that a distant earthquake has generated a tsunami that is going

to impact on our coast and information indicates that large scale evacuation is

necessary, then a declaration of state of local emergency needs to be made to make

sure people are evacuating.

Public Notification

This will be through CD community link structure, radio, emails, texts, Facebook and GDC

websites, asking people to leave the inundation areas.

Evacuation

Once the decision is made to evacuate, the road blocks will go in as soon as practical

after the receipt of the warning. The evacuations will begin 6 hours prior to the expected

arrival time. Residents will be allowed in and out until 3 hours before impact.

The Traffic Management Plan (TMP) should be timed to be in place before the

evacuations begin.


28

All Clear Procedures No/or insignificant inundation

If no inundation occurs, or it is insignificant, and it is clear that there is no further threat, an

all clear message will be broadcast on all radio stations and announced at the

evacuation centres.

Before the message is broadcast it must be signed off by the Group Controller and the

senior Police Officer.

All ‘partners,’ including MCDEM, should be notified as soon as possible if they are not part

of the meeting that makes the decision.

The all-clear message should comprise the following information:

Messaging is based around ‘look after yourselves, listen to the radio and do the following:’

Stay away from the Coast until the all clear is given by Tairāwhiti CDEM (this may be

via Community Link and Media)

Return home if advised to do so by Tairāwhiti CDEM or your Area Community Link.

Information would have come from Tairāwhiti CDEM

Welfare Arrangements Mission

To provide immediate welfare assistance to evacuees.

Welfare Response Objectives

1. Deploy rapid needs assessment teams to gathering points to:

Triage those with immediate needs

Conduct rapid registration to facilitate potential future welfare needs

First aid

Provide reassurance

Identify, support and supervise unaccompanied minors

Establish communications with ECC

Deliver essential goods/catering (as capacity allows)

These teams will be made up from CDEM Volunteers, Red Cross and the Salvation

Army.

2. Establish centralised coordinated welfare response which provides for all

Tairāwhiti’s communities.

a) Activation of the Welfare Coordination Group and relevant sub functions

b) Coordination with the area welfare managers

c) Activation of central welfare function which would operate from the ECC and be a

single welfare team for the region to:

Establish liaison with impacted communities

Plan and coordinate initial welfare response

Plan and coordinate rapid and ongoing needs assessments

Plan for welfare delivery in response to identified needs

Coordinate welfare planning across the welfare sub functions

Coordinate delivery of welfare services

Plan for and deliver emergency accommodation

Plan for and deliver household goods and services

Considerations

Daytime (inside or outside of school hours)/Night time

Weekday versus weekend

Public Holidays

Weather and season

Public/Community/Sporting Events

Security of facilities

Safety of staff


39

The Area Welfare Centre is situated at the Salvation Army’s Worship and Community

Centre 389 Gladstone Road, Gisborne.

Community Emergency Centres Immediate Actions (of Volunteers)

After own safety and that of their families is established, volunteers will do the following:

Those from both the rural and urban communities will gather at their identified

community emergency centres and support the needs of their local community

CD Volunteers may be operating from Community Emergency Centres (Appendix 4) and

are unlikely to have adequate resources in place. They will need to be resourced as soon

as they can.

The CECs have base radios to be able to communicate with the ECC.

It is expected that due to limited initial resources rapid needs assessment teams will begin

the immediate welfare response which can be built on with further coordinated planning.

Coordination & Deployment of Teams

On assembly the following will occur;

1. Teams will be coordinated and tasked by the ECC; this will be effected via agency

liaison personnel either at the ECC or located on the ground

2. ECC will conduct a briefing outlining the situation, location and where to deploy

3. ECC will provide registration/needs assessment forms and instructions

4. Teams will be configured to achieve the optimum mix of skills to be able to fulfil the

task

First aid

Supervision of unaccompanied minors

Communications

Triage of Evacuees Priority Need Action/s

1 Medical (physical & mental)

First Aid Transfer to medical facility

2 Unaccompanied Minor

3 Other urgent needs Provide support as resources allow 4 Wet/cold/not adequately clothed Provide support as resources allow 5 Any other needs prioritising families

with infants, young children, the elderly, and those with disabilities

Provide support as resources allow


40

Planning Assessment

Evacuation and

Gathering Up to 4 hours 4 + hours

Assumptions People will either: • self-evacuate on long or

strong earthquakes • evacuate on advisory

from family/friends/word of mouth

• evacuate on receiving Red Cross alert

• be unable or unwilling to evacuate

People will go to: • friends and families • nearby high ground • known gathering points* • places in town eg.

supermarket car parks

Evacuees will fend for themselves or be supported by friends/family or the wider community (community led response) Radio messaging will be important to advise any of the following:

• Return home (if advised to do so)

• Go to friends and families out of evacuation zone (rely on road access)

• Sit tight or look after yourselves (if able to do so)

• If you have needs come to an identified gathering point

If all clear isn’t given people will be tired, hungry and anxious/frustrated/upset Will have basic needs that need to be met: food, warmth, sanitation People with ill health, medical conditions, the elderly and very young will be more vulnerable Tourists with no local connections or resources could be vulnerable Weather and time of the day may increase needs

Welfare Response

Agencies ensure personal safety and that of their families

• Activate BCPs

ECC activated and welfare team established

• Receive data from emergency services and others to confirm gathering points and needs

• Assemble and deploy Rapid Needs Assessment teams

Deploy Rapid Needs Assessment teams • Planning for next

few hours begins • Establishment of call

centre/s


41

Transition to Planned Welfare Response

As coordination and situational awareness is established the Welfare Function at the ECC

in conjunction with the incident management team will plan beyond the initial response.

In the event of actual tsunami and/or earthquake damage the plan will likely consider:

Formalised registration and needs assessment

Delivery of welfare services across the welfare sub functions including animal

welfare

Household Goods & Services

Shelter & Accommodation

Psychosocial Support

Care & Protection Services for Children & Young People

Financial Assistance
