Earthquakes at Convergent Plate Boundaries
Imagine a convergent plate boundary where one lithospheric plate subducts beneath another. As the subducting plate descends through the mantle, stress builds up and is released as seismic activity, resulting in earthquakes.
Earthquakes can occur in all three types of convergent plate boundaries: oceanic-oceanic, oceanic-continental, and continental-continental.
In oceanic-oceanic convergence, frequent earthquakes occur when one oceanic plate subducts beneath another. One example is the 2011 Tōhoku earthquake, which occurred between the Pacific and North American tectonic plates in northeastern Japan and triggered a devastating tsunami.
In oceanic-continental convergence, like in the Pacific Northwest of the United States, the subduction of oceanic plates beneath the North American plate forms the active volcanoes, the Cascades. It poses a risk of massive earthquakes every few centuries.
Continental-continental collisions, such as those forming the Himalayas, also produce powerful earthquakes. During these collisions, landmasses push against each other, raising mountain ranges and generating significant seismic activity.
Another example of this is the 2015 Gorkha earthquake in Nepal, which occurred between the Indian and Eurasian plates.
