How a Volcano in Japan Halted an Earthquake

Mount Aso, one of the most active volcanoes in Japan, recently helped to stop a powerful earthquake before it subsided on its own, researchers discovered. When a 7.1-magnitude quake struck Kumamoto, Japan, on April 16, 2016, it opened surface ruptures in a zone extending 25 miles (40 kilometers) in length. This topic is of particular interest in Japan, which is particularly vulnerable to both volcanoes and earthquakes.
