Idaho gets real earthquakes, though far fewer than the West Coast. Since 1900 the USGS has recorded 687 of magnitude 3.5 or more, and 19 reached magnitude 5. Below: every quake in the state this week, a map, and the biggest since 1900.
Older decades look quieter partly because there were far fewer seismometers. Counts before about 1970 are incomplete.
