Rapid Understanding of Earthquake Impacts
The California Earthquake Clearinghouse
Maggie OrtizEarthquake Engineering Research Institute
The California Earthquake Clearinghouse
Consortium of organizations Established in 1972 More than 10 activations
Role in Post-Earthquake Investigations
Facilitate coordination of post-earthquake field investigations and shares observations after a damaging California earthquake› Badging› End of day clearinghouse meetings
Relay relevant information to CalOES that can inform and speed up recovery process
What is relevant information?
Researchers, scientists, and practitioners will collect a variety of information:› Structural damage observations› Ground displacement measurements
Clearinghouse will monitor all incoming observations and extract observations that will provide situational awareness to emergency responders
Situational Awareness
Timeline: › ~5 minutes: Shakemap› ~30 minutes: HAZUS run initiated› ~60 minutes: HAZUS results› ~24 hours: Clear picture of what is actually
happening Decisions about aid requests need to
be made in the first 30 minutes - hour
Situational Awareness
Decisions about aid informed by local reports and damage estimates from HAZUS
Decisions made before the physical Clearinghouse is established
A virtual clearinghouse concept allows for sharing observations within a few hours of the event
This “ground-truthing” by experts along with information from local governments can inform the aid distribution process
Types of observations
Lifelines experts: in investigating effects on lifelines systems may inform the Clearinghouse of areas without water service or power
Structural engineers: general observations of damage in different areas can be compared with HAZUS estimates
Two-way street: HAZUS results can help reconnaissance teams decide where to go and observations in these areas help calibrate HAZUS models
Capturing the Data
Researchers and scientists will each have their own data collection methods
Need to have an interface that allows them to report urgent information outside of their normal protocol
The Clearinghouse is investigating a suite of mobile data collection tools as well as a data sharing app: SpotOnResponse
Data Collection: FieldNotes
Basics: Native app for iOS and Android phones. Record geotagged and data and time stamped notes.
Features› long text description › Annotated and captioned
photos› Audio and video clips
Sharing:› FNZ, KMZ, text file, PDF› Email, iTunes, DropBox,
FTP
Data Collection: Clearinghouse Fieldnotes Basics: Operating system
independent Html 5 web application
Features: › Geolocated› Text, photo› Discipline specific forms
Sharing: › Data stored in application
database› Records visible on the
application map or downloaded for viewing in other mapping applications
Data Sharing: SpotOnResponse Basics: Situational
awareness tool with data collection capabilities (in development)› Html 5 web application
Features: › map giving an overall sense
of the situation› Can import data from other
sources such as FieldNotesPro and Clearinghouse Fieldnotes
Sharing: › SpotOnResponse map can
be monitored in SOC and at Clearinghouse
Communicating with Emergency Managers
Continuing to improve ease of identifying important observations
A Clearinghouse seat in State Operations Center (SOC) will make it easier to communicate directly with emergency managers
Clearinghouse Representative monitoring SpotOnResponse and in direct communication with Clearinghouse physical location
How will it work?
The last major Clearinghouse activation was in 1994 after the Northridge earthquake
Notes from clearinghouse meetings informed emergency response
New technology presents its own challenges, but through exercises, the Clearinghouse is working to more quickly inform emergency responders, speed up the recovery process, and improve the resilience of California
