While we don't have big earthquakes here frequently, Indiana has small earthquakes due to fault lines and our soil makeup.

All earthquakes start at one point called an epicenter and radiate out. This can cause tsunamis when it occurs near an ocean.
Earthquakes are measured with the Richter Scale.

How long does volcanic activity take?
How long does volcanic activity take?
Volcanic activity is a fast process. It can take seconds or last for years.
How long does a landslide or avalanche take?
How long does a landslide or avalanche take?
They are typically very fast, taking seconds, but rarely landslides/avalanches move gradually at a few inches a day.
