Samoan Islands earthquake. 2009
• • •
•
Magnitude=8.0 September 29, 2009 It was hit on three countries (islands). 1. Independent State of Samoa 2. American Samoa 3. Tonga
•
The quake occurred on the outer rise of the Kermadec-Tonga Subduction Zone. This is part of the Pacific Ring of Fire, where tectonic plates in the Earth's lithosphere meet and earthquakes and volcanic activity are common.
•
The Kermadec-Tonga Subduction Zone is a convergent plate boundary which stretches from the North Island of New Zealand northward, and includes the Hikurangi Trough, the Kermadec Trench and the Tonga Trench. Along this zone, the Pacific Plate to the east is subducting beneath the Indo-Australian Plate.The southern end of the subduction zone transitions to a right lateral-moving transform fault south of the North Island called the Alpine Fault.
