Hundreds of small earthquakes happen every day, most of which go unfelt. A magnitude 8 earthquake usually occurs somewhere on the earth once every year. The largest earthquake in Nevada was the 1915 Pleasant Valley earthquake, which had a magnitude of 7.3. Thank you for reading this. Please email back if you have a chance.
Volcanos can trigger earthquakes by the movement of magma in the volcano.
Single earthquakes do not result in the creation of a volcano, but it is common that when volcanos erupt, there are earthquakes at the same time. I was wondering when and where the biggest earthquake ever recorded was and when it happened. I've never felt one here. It happened at 39.2 degrees North, 96.3 degrees West, in an area northwest of Topeka. The U.S. Geological Survey also lists major earthquakes for each state .
