Yellowstone Caldera, WY

Feb. 19-20, 2019 Minor Rapid-Fire Swarm at Northern Tip of Yellowstone Lake

2/19/2019

0 Comments

 
The video above quickly shows analysis of the small rapid fire swarm that just recently took place likely under the northern tip of Yellowstone Lake. The amplitudes were not great, barely exceeding 4,100 amplitude count for the largest event, but the swarm was followed by a great many low amplitude low frequency seismic events. These tiny "poppings" were not present prior to the swarm and occurred right when the swarm ended. As of an hour ago or so, right now is 5:50UTC February 20, 2019 (9:50pm PST Feb. 19, 2019), the low frequency weak "popping" has calmed and was only seen after the swarm. This is quite odd and shows the small LF events after the swarm are likely connected to the swarm itself.

Please CLICK HERE to visit the link of the video above. It does NOT contain as accurate of a description as the analysis in this post. Please click the title of this post or "read more" if you haven't already.

Feb. 16, 2019 Mary Lake Swarm

Picture
On February 16, 2019 a small but energetic swarm struck right near Mary Lake at Yellowstone. This type of rapid fire activity does occur at many locations within Yellowstone, but most of the time the most energetic swarms are centered around Yellowstone Lake and West Thumb Lake. Please CLICK HERE if you wish to see my page dedicated to 18 rapid fire earthquake swarms near West Thumb Lake from 2018 to 2014. Prior to 2014, it was hard to find these at such quantity. However, I am getting off topic. If you wish to see the Feb. 16, 2019 rapid fire swarm near Mary Lake, which contained approximately 20 micro-quakes within 13 minutes, then please click the title of this post or "read more" to continue.

Jan. 23, 2019 Shoshone Lake/Lewis Lake Swarm

2/11/2019

0 Comments

 
The video directly above is of the spectrogram stream for station YDD for the main burst of seismicity that occurred between Shoshone Lake and Lewis Lake at Yellowstone on January 23, 2019. This swarm was another rapid fire swarm, most of which usually occur near West Thumb Lake or Yellowstone Lake. Please CLICK HERE to see my page dedicated to the rapid fire swarms that occur in and around West Thumb Lake and Yellowstone Lake. It contains ALOT of data and info but the best swarms are highlighted! To view the data and info regarding the January 23, 2019 rapid fire swarm near Shoshone Lake and Lewis Lake, please click the title of this post or "read more".

    About

    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.
