I recently uploaded a video detailing the re-emergence of a very strange vibration. It carries dominant low frequencies of around 0.1HZ-0.3HZ but the weirdest thing about this event is the fact that it is showing on a large majority of seismic stations from Washington state all the way to the east coast in New York. Whatever this may be, it has been seen before. This vibration is one of the first puzzling discoveries I ever made in regards to seismology. This vibration/tremor is quite strong, though not strong enough to feel, and lasted about 36 hours or so from around 1:00UTC October 27, 2018 to around 12:00UTC October 28, 2018. It is hard to pick a definite beginning for this event since it is very emergent (meaning it is very slow-building). This post will quickly show new data sources that confirm beyond a shadow of a doubt that this "tremor" is quite real and may occur again at any time.

At 4:54PM Mountain Time October 25, 2018 (22:54UTC October 25, 2018) a very large M6.8 earthquake struck off the southern coast of Greece. It was very shallow for an earthquake of this magnitude so it really shook up Greece! This area is seismically active and does have large earthquakes from time to time. The largest was apparently a 7.3 on October 6, 1947. However what is interesting with this earthquake is that there was a smaller foreshock just before the 6.8. Also, about 3 hours later, a magnitude 2.9 earthquake struck Montana just about 20 miles northwest of Bozeman. I will show the helicorders first and then the seismogram/spectrogram plots for these different events. PLEASE CLICK THE TITLE OF THIS POST OR "READ MORE" TO CONTINUE!!! Seismic activity seems to have increased once again at Yellowstone! From 3:17pm Mountain Time October 24, 2018 (21:17UTC October 24, 2018) to 9:06am Mountain Time October 25, 2018 (15:06UTC October 25, 2018) there were two areas that saw an increase in activity virtually around the same time. The Maple Creek area saw an increase as well as the West Thumb lake area. However the earthquakes that occurred near West Thumb lake occurred farther south than we usually see. Seismic station YDD, which resides just a few miles south of YLT, saw these earthquakes arrive first. To continue this post, PLEASE CLICK THE TITLE ABOVE OR CLICK "READ MORE" BELOW! Steamboat geyser is a very large geyser situated in the Norris Geyser Basin in the north section of Yellowstone National Park and Caldera. It has entered a very frequent water eruption phase since March 15, 2018, when its first eruption of 2018 occurred. It has erupted large amounts of super-heated water and blown rocks into the sky a total of 24 times so far this year, at the time of writing this. In this blog post we will take a quick and simple seismological look at Steamboat geyser and the seismic signals it creates. Steamboat needs to erupt 6 more times to beat the record, or 5 more times to match the record, of 29 eruptions in one year. That year in question was 1964. Will she make it?

I am briefly going to show the helicorders and seismogram/spectrogram analysis images for the two earthquakes that recently occurred at Yellowstone on October 21, 2018. These two earthquakes occurred in a very random spot. Usually we see the majority of larger earthquakes (M2.0 and above) occur either near the Maple Creek/Hebgen Lake area, the Norris area, or the northern tip of Yellowstone Lake and West Thumb lake. However today these two earthquakes appear to have occurred at the southern tip of Yellowstone lake, just 2.7 miles south-southwest of seismic station YTP. PLEASE CLICK THE TITLE OF THIS POST TO READ MORE!!! 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!

I know probably almost nobody reads my blog posts, since my website here gets very low views, but I still like to post stuff that interests me. I have been doing more YouTube videos lately than blog posts. Of course this website contains alot of information already that has nothing to do with my blog. I am looking for new suggestions for new pages to add to this website so please feel free to email me or comment below (if the comment box is working).
Texas felt a magnitude 4.0 earthquake today at 5.3km in depth just 15km NNE of Amarillo, Texas. The two images directly below show the basic information provided by USGS and the location of this earthquake. As of the time I am writing this over 1,055 people have REPORTED feeling this quake. That means many more actually felt it since not everybody reports to the USGS. PLEASE CLICK THE TITLE OF THIS ARTICLE OR CLICK "READ MORE" TO READ THE REST OF THIS POST!
