Start of swarm: 0:18UTC
End of swarm: 9:33UTC
Note: This swarm occurred on the southeast tip of Shoshone Lake, which is just to the southwest of West Thumb Lake (also southeast of Old Faithful Geyser). Although the epicenter is slightly farther from West Thumb than the other swarms I have shown, I personally believe this swarm is connected to the same possible processes that cause the rapid-fire swarms at West Thumb Lake. I will use B944 for the plots since it was closest to this swarm (for some reason YPP was not working). Know that there were many, many other very tiny quakes a day before and a day after this earthquake swarm that likely will not be included in the plots below. I am mainly focused on the time period stated above.
Total earthquake count (includes even the tiniest events): ~570 (there may be more but are hard to spot because of the close proximity to other events; this count is ONLY for the time period stated directly above)
Reported count: 53
Magnitudes/Depths of reported events for this swarm from newest to oldest (showing magnitude/depth): There are far too many. Please click the USGS EQ map button that says "CLICK HERE" below.
Largest reported earthquake(s) of this swarm: 2.9 at 3.3km
Largest amplitude: ~32,800 (YLT), ~42,200 (B944)
