EARTHQUAKE

[RugerShooter]

Did you feel today's earthquake?

I did in Ogden. Around 7:18 AM

[Skylinerider]

We felt it here in our office in Sugarhouse.

Just watched the report on Fox13 - SO, is the whole basin gonna go under?

From the usgs website

The following is a release by the United States Geological Survey, National Earthquake Information Center: An earthquake occurred 15 km (10 miles) ESE of Wells, Nevada 15 km (10 miles) ESE of Wells, Nevada at 7:16 AM MST, Feb 21, 2008 (6:16 AM PST in Nevada). The magnitude and location may be revised when additional data and further analysis results are available. No reports of damage or casualties have been received at this time; however, this earthquake may have caused damage due to its location and size.

I feel cheated, everyone in the office felt it except me! I thought they were pulling my leg when someone finally pulled the report online.

I didn't feel it, even though I am in North Ogden now

[tanya]

I have been up since 5am. I felt nothing? But I guess it was not in this area.

[JP]

It did some damage in Nevada

[greyhair biker]

checking out the USGS site for recent activity it looks like the whole state of Utah is a quaking....and did you see Yellowstone?...in the last HOUR? I wouldnt want to be on the continental US when THAT region decides to go

[Kent K25]

Didn't feel a thing...though I haven't heard of anyone feeling it in Provo anyway...?

Probably because I live right next to BYU and God loves me more than you.

[shagster]

I felt it, it woke me up this morning when my bed started shaking. I jumped up to see who was shaking my bed, and no one was there. That's when I realized what it was. It only lasted for about 15-20 sec. but cool either way.

[Mtnman1830]

Didnt feel a thing... I went to bed around 06:30 so I was out...

[sparker1]

I have been up since 5am. I felt nothing?

Bummer.

Brad, here is the REAL data, this is all you need to know about the earthquake... I know, I know, it does look like a bunch of numbers and abbreviations that only a GEEK student of geology would understand or care about, but it is interesting.

The real question is: did this earthquake release enough stress on "the basin" to reduce the potential hazard of another equal or larger earthquake happening soon in the area? if somebody tells you yes dont believe them, they are lying or ignorant. the difference in energy released by a mag 6 and a mag 7 earthquake is 35 times. which means that we would need to experience 35, magnitude 6 quakes, before enough stress was released to reduce the risk of a magnitude 7 quake. or 1,225 magnitude 5 quakes to equal one mag 7. sorry guys, a little too much info. i am sure right?

It screwed Wells, NV pretty good. We couldn't load trucks out there today.
