6.4 Earthquake near Boise

Just felt my first earthquake 6.4. about 100 miles away. Scared me pretty good.

Is that fault line related in any way to the Teton faultline where Yellowstone is? the epicenter is pretty close at 139 miles from the Yellowstone caldera. YIKES!!!

6.4 is pretty big, I hope everyone is ok.
That’s all we need is natural disasters among everything else that’s going on

we just had other unusual earthquakes
3.2 Salt Lake City, Utah on 3-26-20
5.0 Pecos, Texas on 3-26-20
now this one. I wonder if they’re connected.

Did someone start breaking the Seven Seals?

A tornado touched down in the middle of Jonesboro Arkansas on Saturday and went for miles.

Fracking for oil. Oklahoma never had earthquakes before the fracking craze, now the ground down under has been high pressure washed and is all decimated, disturbed and lubricated—just the right conditions for stuff to start moving around. i would guess they are doin’ it in Idaho too.

Interesting. I’m about 300 miles away, but briefly thought I felt a little shaking a few hours ago. If so, it was just strong enough to make me wonder and briefly think about how a major earthquake during a pandemic would be unfortunate, but not confident it wasn’t simply a coincidence that I thought I felt something.

USGS is showing 23:52 UTC, which would be 4:52 PM Pacific Daylight Time.

A station near me shows a signal at 4:54, which would be about right considering the time for the waves to travel that far, but I don’t know how to interpret what they show in terms of acceleration. Detectable on a seismograph is obviously different from noticeable to a person.

Fracking has slowed in OK and so have the quakes. I am guessing in Idaho it is fully Mother Nature at work. No man made help.

Neither of those is unusual. I suppose the Salt Lake City quake could be related, as the Wasatch fault system passes through Salt Lake City, and also near where today’s quake occurred in Utah. But M3+ earthquakes are happening daily somewhere in the US, so it’s not remarkable. Larger than M4.5 happen several dozen times a year, and I don’t see any reason to think the Texas earthquake is related to the Idaho one.

Idaho has a long history of major quakes. The 1983 Borah Peak earthquake was the largest recorded at M6.9, and was fairly close to and at a similar depth as today’s quake.

Oklahoma certainly had quakes before fracking began, but they were rare and became significantly more frequent and intense afterwards, then declined again as limits were placed on wastewater injection.

Never say never

This was classed as a horizontal quake vs the vertical fault quake of 1983 according to scientist Dr. Lucy Jones.

As i was searching i found this:

“Marcus Smith, an emergency room health unit coordinator at St. Luke’s Wood River Medical Center, said the hospital, about 65 miles (104 kilometers) south of the epicenter, shook but the quake didn’t interfere with the treatment of any patients. The hospital in Blaine County is on the front line of Idaho’s coronavirus outbreak, in a region with the nation’s highest per-capita rates of known COVID-19 cases outside of New York City and its surrounding counties.”

How is it that the Cor virus has spread to such an extent, Is it in the wind?

There was a PBS show last night about the 1918 Influenza epidemic traced it back to a big windstorm in Kansas that blew it in to a military base; those soldiers were deployed to Europe where it spread, then it was brought back to US after WW1 and spread again killing 675,000.

One asymptomatic (at least initially) person visits the county, or returns from a visit to another area, and spreads it to 191 other people (count as of today, per Idaho Public Health), which could happen in a month or less. That is roughly equivalent to New York City’s 40,000+ cases on a population-adjusted basis.

I lived out in Hailey years ago, didn’t practice much social distancing if i could help it. So i could see 1 person spreading it to 191 others.

Man they are getting a bunch of after-shocks right on top of the primary site.

I’m from Utah and living in Boise for school, so I missed the 5.7 that hit SLC a few weeks ago… Then I decided to drive home for a few weeks and missed the 6.3.

Good timing.

Yeah you did time it good. Is SLC on the same fault line as Boise?

I don’t believe so, IIRC the Wasatch fault system is almost completely separate from the central Idaho faults, divided by those big stretches of caldera plains.

We just had a 4.9 earthquake near Anza, CA which is near where I live.
