World Tectonic Plates
Tectonics in the Philippines
In the Philippines there is a complexity of plate tectonics where the plate boundaries are changing very quickly. Many micro-plates are being crushed together in between two plates that are moving together.
A chain of volcanoes runs through the length of the Philippines. The volcanoes of the Philippines are the most deadly and costly in the world. Fatalities have been caused by 13% of the historic eruptions, most notably at Taal and Mayon, and 22% of the eruptions caused damage. Mudflows are more common in the Philippines, compared to other regions, because of heavy rains. Tsunami are more commonly associated with eruptions at the Philippines than in any other volcanic region. Volcano

World Tectonic Plates
Tectonics of California
The San Andreas Fault is a conservative plate boundary that runs a length of roughly 810 miles (1,300 km) through California in the United States. It forms the tectonic boundary between the Pacific Plate and the North American Plate.
