A magnitude 8.2 earthquake — a great event — struck near 2012 Wharton Basin Aftershock on April 11, 2012, at a shallow depth of about 25 km. An earthquake this size would have been felt strongly across the surrounding region; shallow earthquakes release their energy close to the surface, so they tend to cause the strongest shaking and the most damage. Shallow magnitude 8.2 events near a coastline can also pose a tsunami risk. 196 people submitted "Did You Feel It?" shaking reports to the USGS.
