ANCHORAGE, Alaska -- A 6.6 magnitude earthquake has rocked buildings in Anchorage, prompting people to run out of offices and seek shelter under office desks. The U.S. Geological Survey says the earthquake was centered about 7 miles north of Alaska's largest city.

Officials issue tsunami warning for coastal areas of southern Alaska after earthquake. There was a tsunami alert for Cook Inlet, the National Weather Service in Anchorage said on Twitter.

How “big” or “huge” the effects of a 7.0 are is depends on more than just the original energy released. Depth of the quake has already been mentioned, and duration also counts. Other major factors are how efficiently the shock waves are transmitted (the largest of the New Madrid quakes in 1811-1812 reputedly rang church bells in New England!), and whether the soil(s) liquify (which was also devastating in the New Madrid quakes.) The New Madrid quakes of 1811-12 were much larger, of course, but even a 7.0 there any time in the near future could largely destroy some of the nearby towns.

(So much for my initial proofread!)

I work on the 4th floor of offices at Dimond Center. Biggest and longest quake I’ve been in. Open shelves emptied and CPUs and monitors fell over. As soon as aftershocks started, security started pounding on doors and we were told to evacuate the building. Then sent home. I live in town and it took almost 2 hours to get home...very few traffic lights worked, and folks forget that that means a 4 way stop. Aftershocks the whole way and they continue.

Power finally came back on a couple hours after I got home. Lots of cupboard and drawers open and stuff all over the floors. All TVs and computer monitors stayed upright.

Usgs map doesn’t state. It is a n-s trending fault front mechanism analysis.

Consider:

The magnitude scale is really comparing amplitudes of waves on a seismogram, not the STRENGTH (energy) of the quakes. So, a magnitude 8.7 is 794 times bigger than a 5.8 quake as measured on seismograms, but the 8.7 quake is about 23,000 times STRONGER than the 5.8!

Since it is really the energy or strength that knocks down buildings, this is really the more important comparison. This means that it would take about 23,000 quakes of magnitude 5.8 to equal the energy released by one magnitude 8.7 event. Here's how we get that number: One whole unit of magnitude represents approximately 32 times (actually 10**1.5 times) the energy, based on a long-standing empirical formula that says log(E) is proportional to 1.5M, where E is energy and M is magnitude. This means that a change of 0.1 in magnitude is about 1.4 times the energy release. Therefore, using the shortcut shown earlier for the amplitude calculation, the energy is,

32 * 32 * 32 / 1.4 = 23,405 or about 23,000

So, a 7.0 is significantly stronger than a 6.9 - 40% stronger. The San Fran earthquake of 1989 was a 6.9 and it brought down freeways.

Erosion? Don't think so.

Oh My Gosh Kathy!

I am happy you are safe.

The one earlier this year was higher on the scale I think, this one seemed really to hit hard though.

Prayers for you and yours.

Where is the steel reenforcement in the concrete?
Looks built incorrectly.

That road appears to cross a small ravine.

Perhaps soil liquification took place in the fill dirt under the pavement
