Extinct undersea volcanoes squashed under Earth's crust cause tsunami earthquakes, according to new research

New research has revealed the causes and warning signs of rare tsunami earthquakes, which may lead to improved detection measuresNew research has revealed the causes and warning signs of rare tsunami earthquakes, which may lead to improved detection measures.Tsunami earthquakes happen at relatively shallow depths in the ocean and are small in terms of their magnitude. However, they create very large tsunamis, with some earthquakes that only measure 5.6 on the Richter scale generating waves that reach up to ten metres when they hit the shore.A global network of seismometers enables researchers to detect even the smallest earthquakes. However, the challenge has been to determine which small magnitude events are likely to cause large tsunamis.In 1992, a magnitude 7.2 tsunami earthquake occurr… »
