Yellowstone Caldera, WY

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...

June 15, 2019 swarm
 
Start of swarm: 10:13UTC
End of swarm: 10:21UTC (Total of 8 minutes.)
Total earthquake count (includes even the tiniest, unreported events): ~30 events of all sizes.
Reported count: None yet. Keep checking the USGS EQ map to see if they have reported any.
Largest reported earthquake of this swarm: None reported yet.
Largest amplitude: ~25,000 (B208-EHZ), ~8,400 (YLA-EHZ)
Severity: Very minor

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!

    Please click a post title to view the data pertaining to that event!

    This is the seismic events page for Yellowstone National Park and Caldera, which resides in northwest Wyoming. Yellowstone is an absolutely massive caldera super-volcano. It sits at a shocking perimeter of 34 by 45 miles (55 by 72km) and that is only the caldera boundary! A caldera is created when land immediately erupts and collapses, while the magma chamber almost completely empties, creating a crater imprint called a caldera. Some calderas around the world are small in comparison (i.e. Kilauea) to other calderas formed by super-volcanic eruptions (i.e. Yellowstone in Wyoming or Long Valley in California).  Yellowstone is theorized to contain a magma chamber and a much deeper, much larger magma reservoir just beneath the chamber. This two-chamber system is also theorized to be caused by a "magma plume". Magma plumes are thought to draw their eruptive ability from deep within our planet, possibly from our lower mantle. That is why volcanoes caused by magma plumes are much more dangerous and far more unpredictable than their counterparts that are caused by normal tectonic forces. Yes, many volcanoes are caused by tectonic forces as one plate attempts to breach or dip beneath another one. A perfect example of this is the Cascade Range on the West Coast of the United States. Many volcanoes in the world are caused by this but some, the more unpredicatble ones, are caused by magma plumes.

    Remember to always pay attention to all chart labels! All images were generated by myself using the IRIS DMC seismic archive and the FREE seismic program S.W.A.R.M.
