June 15 - Very Minor Swarm at Yellowstone Lake

Spectrogram plots of the minor rapid-fire swarm at Yellowstone Lake on June 15, 2019.

A very minor rapid-fire swarm struck somewhere under the northern tip of Yellowstone Lake on June 15, 2019. To see this post, please click the title or "read more" to continue...

If you wish to see which earthquakes in the plots below were reported, simply go to one of the buttons I provided somewhere above that shows you the USGS earthquake map for Yellowstone during this time period. Earthquakes are reported in UTC and the times on the plots are in UTC as well. You can also find the locations of all stations at Yellowstone by looking for one of the two buttons I posted in the beginning of this post. Also, I do not detail every single event of the swarm in the plots below. However, I do try to show most of them. Severity is a personal determination, with the April 11, 2018 swarm acting as a sort of baseline for a major rapid-fire swarm. Severity ranges from minor, to moderate, to major. In rare cases, “extreme” will be used. However, I have not seen a rapid-fire swarm that could ever be labeled as such. But you never know what will happen in the future!

The following is the seismic audio to this earthquake swarm, taken from the seismic station used for the plots above. All seismic audio is best heard when it is sped up. Please use your headphones but be wary of the volume! Every pop or crack you hear is an earthquake. Enjoy!
