Groundwater levels in wells can oscillate up and down when seismic waves pass. The water level might remain higher or lower for a period of time after the seismic waves end, but sometimes a long-term offset of groundwater levels follows an earthquake. The largest recorded earthquake-induced offset in a well is a one meter rise.

For the next week, we estimate an elevated chance of such an earthquake to be less than 1 in 1,000. Historically, this area has seen swarms before – most recently in 2001, 2009, and 2016. The intensity levels I of two earthquakes measured on a seismograph can be compared by the formula log I 1 I 2 = M 1 − M 2 log I 1 I 2 = M 1 − M 2 where M M is the magnitude given by the Richter Scale. In August 2009, an earthquake of magnitude 6.1 hit Honshu, Japan.

The Modified Mercalli intensity scale ( MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth. 2010 Haiti earthquake, magnitude 7.0 earthquake that struck some 15 miles (25 km) southwest of the Haitian capital of Port-au-Prince on January 12, 2010.
