This map is centered on our home and farm. There were 152 earthquakes reported by the USGS between January 1, 2008 and December 31, 2008 with an epicenter within 30 miles (48 km) of our home. (There have been more reported, but earthquakes centered on known gravel pits and indicating the movement is centered at the surface have been discarded as gravel pit blasting.) The stongest earthquake in 2008 was a 2.8 magnitude quake that occurred November 25, 2008. The shakiest day of 2008 is shared by 3 dates, each with 4 quakes: April 5, May 1, and November 17.
The markers used to show epicenters are sized relative to the size of the earthquake.
The markers are:
If your mouse hovers over a pushpin the date and magnitude of the quake will be displayed.
Oldest earthquakes are displayed first, so newer quake pegs may cover older quakes.
Purple rings indicate 10 mile (16km) distance from the farm.
