Casper & Glenrock Wyoming JOLTED by 3.7 Quake
Sunday night, 08/01/21, the earth rolled in central Wyoming. I slept through it. Did you?
The first I heard of this quake was when a friend told me he felt it, and it scared the heck out of him. Later I found comments on social media:
"Something just shook our house big time for about 2 seconds. Got our attention for sure! We don't see any damage this far. 5 miles east of Casper." Ed Good
I guess "ROLLING HILLS" Wyoming really earned its name this time.
M 3.7 - 11 km NW of Rolling Hills, Wyoming.
The US Geological Survey has confirmed a 3.7-magnitude earthquake occurred Sunday night at 9:50 p.m.
According to a Michigan Tech seismology site, a 3.7-magnitude earthquake is classified as a “minor." It's just enough to make you ask "WHAT THE &$#@ WAS THAT?" Nothing more will happen.
These events are not unusual. About 30,000 such quakes around the world each year. Most are so light or so deep we don't even notice them. Now and then they are high enough or big enough it can rattle our windows.
Looking into this a bit more I found that small earthquakes are tracked daily worldwide.
During the past 30 days, Wyoming was shaken by 1 quake of magnitude 4.1, 5 quakes between 3.0 and 4.0, and 49 quakes between 2.0 and 3.0. There were also 232 quakes below magnitude 2.0 which people don't normally feel.
Biggest quake: 4.1 quake 39 mi southeast of Worland, Washakie County, Wyoming, USA, 4 Jul 3:17 pm (GMT -6) 4 weeks ago
Biggest quake today: 3.7 quake Converse County, 21 mi northeast of Casper, Natrona County, Wyoming, USA, 1 Aug 2021 9:50 pm (GMT -6) 7 hours ago
As you might imagine Yellowstone is Wyoming's biggest "offender" with earthquake swarms happening every year. That is actually a good thing because it releases pressures a little bit at a time over time. It's either that or THE BIG ONE, and nobody want's to be around for that.
Most quakes in Yellowstone go unnoticed by life on the surface. But geologists see it, all day, almost every day.
Are you in the area that felt the quake? Have you ever felt one? I haven't. I've always wanted to but never have. This first time it happens right under me I was asleep.
