October 19-20, 2018 Yellowstone Seismicity

Hey there guys! In this blog post I am simply going to show some helicorders and seismogram/spectrogram analysis images of recent seismicity at Yellowstone caldera for 00:00UTC October 19, 2018 to about 21:10UTC October 20, 2018, since that is the time I am writing this. Remember, before Daylight savings time ends, 00:00UTC would be 5:00pm (17:00) Pacific Time. After daylight savings time ends, in about 2 weeks or so, 00:00UTC will then be 4:00pm (16:00) Pacific Time. I know it sounds confusing but it is really easy to figure out!

With all the hydrothermal changes still occurring at Yellowstone, it is surprising seismicity has remained low. It has been low in regards to what we should see during hydrothermal changes. Nevertheless I am still sticking to my theory that a major earthquake swarm still could be approaching. Please monitor this area with me! PLEASE CLICK THE TITLE OF THIS PAGE OR CLICK "READ MORE" TO READ THE REST OF THIS POST!

Since the seismicity for this time period remained near the Maple Creek area, which would be northwest Yellowstone, I will be using seismic stations WY_YMC_01_EHZ (Maple Creek) and WY_YHH_01_EHZ (Holmes Hill) for this analysis. However since most of the earthquakes appeared best on YMC, I will use only seismic station YMC for the seismogram/spectrogram analysis images. Both stations are short period vertical and remember to always pay attention to chart labels FIRST before you read the data. Also pay attention to time period, frequency ranges (spectrogram), amplitude counts (seismogram) and all times are in UTC as usual.

First I will show the helicorders for this time period for YMC and YHH and then I will show the seismogram/spectrogram images. Now I am not going to show the seismogram/spectrogram analysis image for every single earthquake that occurred. However I will try to show the majority of them. You know, you could do this stuff yourself even with a simple understanding of seismology! My website here helps you to do that so feel free to browse my site! So, enjoy!
