Cali's been shaking, but this 7.4 just hit about 40 miles offshore from El Salvador and about 100 miles south and offshore from the capital of San Salvador.

No word yet on any tsunami or damage. It's about 40 miles deep.

Pretty deep quake, usually the shallow ones (20 miles or less) are the ones that really cause destruction. Hopefully everyone's okay!

This actually isn't all that deep. Quakes are commonly felt hundreds of miles down. This was just a little more than 50 miles down. And remember...the people who live in this area often live in inadequate structures.

Similar quakes in the same area have caused widespread damage. Often from either tsunami's or landslides.

Yeah...seeing the tsunami warnings now.

This page has some pretty good info on historical data for quakes in the area and their outcomes. From little damage to massive loss of live from secondary events.

The 2 columns on the end represent initial deaths, and total deaths including secondary and primary means.



**30 6.5 Nicaragua 12.168, -88.34, 26km1995-06-14 11:11:49 VI (561,350) 0 0

**40 6.7 Nicaragua 11.706, -87.998, 12km1998-08-23 13:57:11 VI (650,155) 0 0

And the quakes I selected are a couple as indicated on the map close to the same area. Obviously the third one with all of the deaths was the closest in size to the current one.
