Understanding subduction zone earthquakes: The 2004 Sumatra earthquake Date: June 23, 2015 Source: Geological Society of America Summary: The 26 December 2004 Mw ~9.2 Indian Ocean earthquake (also ...

The subduction of topographic features has been linked both to earthquake generation and the segmentation of faults. Seismic imaging reveals a seamount subducted to 40-km depth below Sumatra that ...

The subduction zone that brought us the 2004 Sumatra-Andaman earthquake and tsunami is ripe for yet another large event, despite a sequence of quakes that occurred in the Mentawai Islands area in ...

In 2011, the seafloor jolted and sent waves up to 133 feet (41 meters) high over parts of Japan. In 2004, the entire planet vibrated as an undersea quake near Sumatra pushed tsunamis over ...

This subduction zone is quite similar to the Sumatra earthquake region. The last Cascadia earthquake was estimated to have a magnitude of 9.0 and occurred in January 1700, generating a Pacific ...

An earthquake with a magnitude of 8 or greater in the Cascadia Subduction Zone could cause coastal land to sink more than 6.5 feet and expand the 100-year flood plain, an area with at least a 1% ...

The Chilean subduction zone is geologically active enough to provide useful information and is a good locale for comparative studies with Cascadia and Alaska. The SZ4D implementation plan recommends ...
