Quake Watch 2012

reply to post by shaneR

So does anyone here know what a "slow moving earthquake" is?
Never heard this one before

from the USGS Phase data page for
OFFSHORE EL SALVADOR
MAGNITUDE 7.4 (GS)
mb = 5.9 (298) ML = 5.6 ( 7)
neic.usgs.gov...

something isn't right

Does anyone here think that TS Isaac has anything to do with the increase?

It's doubtful that has any effect, that's near Florida heading up through the US from the gulf.

Some more activity in the next few minutes I think.

Are you thinking downgrade?

I'd say S. Cali might come to life a little more with that energy ringing through the earth.

...And Muzzy, that is odd.

NZ didn't want to feel left out.

Have her putting off a 4?

You're right. Looking at all of the contributing stations, the largest magnitude I saw was 6.7.
Maybe it has something to do with it being referred to as "slow" (by NOAA--in the tsunami warning)?
Long duration = higher magnitude?

Interesting article on the relationships of hurricanes and earthquakes:

A new study suggests that earthquakes, including the big temblors in Haiti and Taiwan in 2010, might have been triggered by tropical cyclones.

Researchers analyzed data from quakes of magnitude-6 and above in Taiwan and Haiti and found a strong relationship between the two, with large earthquakes occurring within a four-year window following a very wet tropical cyclone season.

A 7.4 magnitude earthquake hit 78 miles off the coast of El Salvador early Monday, the U.S. Geological Survey says.
No tsunami warnings were issued, and the temblor's epicenter was deep beneath the ocean's surface, the USGS says.
There were no immediate reports of damage or injuries.
There was a report of someone feeling the quake in San Salvador, the USGS adds.

What time was that issued? Seems we would have conflicting tsunami reports.

wtf???

hmm seems to be gone now

Muzzy, check out this seismic magnitude parameters page for the Nicaraguan EQ.
They look much more reasonable for a Mag 7.4.

You have to "toggle data visability" button near the bottom of the page

This was from CBS News.

You are right. Too many news agencies are saying a T warning WAS issued. I think CBS got it wrong.
