Intermountain Corridor UT to Yellowstone Seismic Activity

Yet another quiet week in earth moving activity in the Intermountain Corridor.

The map shows 21 earthquakes for the week from Southern Utah to north of Yellowstone.

Most of the events were between 1.5 and 2.0 ~ in the micro category.

Over the last month, activity has been relatively slight. I live at approximately the cross-over of the X drawn corner to corner on the map, in Sandy UT.

Events occur to the north and to the south at varying distances. Each week the pattern changes, suggesting that events might occur anywhere in my observed area.

This week, there is little indication that anyone reported that they felt any of the activity.

The map represents my area of interest for my hobby of observing seismic activity.  As always my comments are made to inform, never to alarm.

Larry, when the recent earthquake occurred in VA over the summer, I was sitting in our local Library.  The floor felt like a trampoline, the ceiling shook....I was waiting for the books to begin falling off of the shelves.

My first earthquake.  So strange.....

It's amazing how sensitive the measurements become.  But...when it comes to the great's fun to experience.

Chris - good visual description. My first experience of a tremor was in San Francisco in 1982. I was white knuckled but locals took it in their stride.

Larry - the seismographs are relatively simple machines that have stood the test of time. My machine was located at the Post Office. As a six year old visiting town , I got to post the letters (remember them?) so I saw the machine regularly, I always hoped to be there when the inked arm made the wide tracings that looked so good on the papered drum. Simple entertainments ten years before television in my part of Australia.

Most of us never experience any type of noticeable seismic activity and give no thought to the fact that the activity is almost continuous. Thanks for the update! Enjoy the day!
