Where do earthquakes occur?. Plate Tectonics The Ring of Fire.
Earthquakes happen where Earth's plates meet. Most earthquakes happen under the sea. Where the plates stick, pressure builds up and then the earth shakes.
Earthquakes Sudden movement of surface when accumulated strain along opposing sides of a fault is suddenly released. Rock stretches and snaps.
The world was stunned on December 26, 2004 when the powerful Sumatra- Andaman earthquake triggered tsunamis that demolished many coastal areas of South.

Tsunami Tsunami is a Japanese word. Movement of seafloor during an earthquake produces a surge of water that becomes a long sea wave Tsunami.

1960 Chile M= off Sumatra M= Lin & Stein (2004) Southern Segment Northern Segment

Cook & Lin It has the longest fault line ever recorded (1,300 km) It was the largest quake since the 1960 Chile quake (magnitude 9.5) It was relatively shallow (only 10 miles beneath seafloor) The northern rupture zone was in open water, exposing beaches in Thailand
