QUITO, Ecuador, Jan 31 (Reuters) - Hundreds of earth tremors off the coast of Ecuador in the past 11 days have sparked fears that a bigger quake could strike soon.

"This isn't normal," the director of Geophysics Institute at the National Polytechnic School, Hugo Yepez, told Reuters on Monday, "This area is capable of producing big earthquakes. Very big earthquakes."

About 320 tremors of more than 4.0 on the Richter scale have shaken the Pacific Ocean off the port of Manta since Jan. 20.

So far no one has been reported hurt but some small fishing villages have seen damages. An earthquake measured at 7.9 on the Richter scale battered the Pacific city of Guayaquil in 1942, although fragmentary reports from the time did not mention casualties.

The shape of Ecuador's coastline would prevent the formation of a tsunami like the one which smashed into parts of Asia in December, experts say.

IIRC, the largest quake ever in history (recorded history) was a 9.5 off the coast of S. America in 1960, I think.

Yup.

The largest earthquake ever recorded by seismometers (the 1960 Chilean event with 9.5 Mw ) had a seismic moment equivalent to the energy of 9 trillion kilotons of TNT!

That's a good question, DB.

They aren't kidding about hundreds of quakes.

Good research, DJF. Hopefully these 6.0+ quakes won't lead to anything that large.

Yup. Decimal points for Dummies tells us that's equivalent to 9.5 billion megatons.

Pretty soon we will have the naysayers showing up telling us that this is all normal activity, nothing to get excited about, it can't possibly be connected, ad nauseum, as nauseum.

Yet the recent 9.0 was the biggest event by far since the 1964 9.2 at Prince William in Alaska. That quake was the second largest in history, in fact 5 or 6 of the ten greatest quakes ever occurred in the 50's and 60's.

So the 9.0, which adds up to about the 4th largest quake ever recorded, could indeed signal a newly awakened period of heightened seismicity.

The current 7 day California earthquake map has 288 quakes on it...

Is there an equivalent map of California showing all quakes since 1990 (similar to the one you posted)?

Well the only thing I'd say is that we haven't been recording the actual strength of quakes with instruments very long in the scheme of things. With such a short time record it is really hard to know what is "normal". The ring of fire seems pretty active lately though...

320 in ten days. I would be a nervous wreck, being earthquake phobic and all.

I would be saying "Oh GOD" alot and not in the passionate immoral whoring way.

It's a second one. I posted three of the most recent and largest quakes occurring in Ecuador.

Yep, the 6.0+ quakes would be over the top for me as well. Two of them in one day would not be fun. Sometimes anything over a 5.5 is enough to trigger a case of the eeby jeebies, LOL.

If by "lately" you mean "the last 50 million years."

There hasn't been a Magnitude 7.0+ quake for the entire month of January. Normally there are 18 of those a year, or more than 1 per month.
