GRCC seismometer records Idaho earthquake, North Korean explosion

This past weekend, the GRCC seismic station in Calkins, GRMI, recorded a flurry of events. Most prominent was a magnitude 5.3 earthquake in Soda Springs, Idaho, just before midnight on September 2. Small aftershocks and more events in Soda Springs were recorded in the following 24 hours. Another notable event is marked by the red arrow on the image below, this coincides well with the timing of an explosion in North Korea, recorded by seismometers around the world. For more information about this event and others, go to the USGS’s website.
