Current Aviation Color Code: GREEN

The real-time computer system located five small earthquakes in the vicinity of Long Valley caldera since the last update at 9:34 AM(PST) on January 11, 2010. Four with magnitudes between M=0.2 and 0.3 were located beneath Mammoth Mountain. The first occurred at 5:19 PM on the 11th, and the remaining three events in rapid succession between 5:36 and 5:37 AM on the 12th. A M=1.2 earthquake at 1:14 PM on the 11th was located in the Sierra Nevada south of the caldera (13 miles SW of Tom's Place).

_______________

Although there were 4 in very rapid succession, these are TINY. Interested to see what today and tomorrow bring.

Earthquake in Jamaica region, according to Twitter. Let's see what the magnitude is, will edit and post report.

Actually it was closer to Haiti, and big!

There's a thread on the Haiti quake so I won't repost my thoughts on that here, but I do feel some concern for the Puerto Rico region which has seen a large number of small quakes over the course of the past few weeks.

Here are the historic large earthquakes for the Carribbean:

Caribbean Sea

1692 06 07 - Jamaica Fatalities 2,000
1787 05 02 - Puerto Rico - M 8.0
1843 02 08 - Leeward Islands - M 8.3 Fatalities 5,000
1867 11 18 - Puerto Rico Region
1907 01 14 - Kingston, Jamaica - M 6.5 Fatalities 1,000
1918 10 11 - Mona Passage - M 7.5 Fatalities 116
1946 08 04 - Samana, Dominican Republic - M 8.0 Fatalities 100
1969 12 25 - Guadeloupe, Leeward Islands - M 7.2
1974 10 08 - Leeward Islands - M 7.5
2004 11 21 - Leeward Islands - M 6.3 Fatalities 1
2004 12 14 - Cayman Islands Region - M 6.8
2006 09 10 - Gulf of Mexico - M 5.8
2007 11 29 - Martinique Region, Windward Islands - M 7.4 Fatalities 1

As you can see, large earthquakes do occasionally occur in the region but not on this particular fault, according to the official summary for today's quake:

The location and focal mechanism of the earthquake are consistent with the event having occurred as left-lateral strike slip faulting on the Enriquillo-Plaintain Garden fault system. This fault system accommodates about 7 mm/y, nearly half the overall motion between the Caribbean plate and North America plate.

The Enriquillo-Plaintain Garden fault system has not produced a major earthquake in recent decades. The EPGFZ is the likely source of historical large earthquakes in 1860, 1770, 1761, 1751, 1684, 1673, and 1618, though none of these has been confirmed in the field as associated with this fault.

I don't really know how to synthesize all of this. I'd love to hear others thoughts.

Can we trust RSOE as a reliable source? There was talk over on the HAITI thread about that 6.1 in the Bahamas, but USGS hasn't confirmed it, and i noticed at the top of the update for it, it said that the warning was generated by a computer and was yet to be looked at by a seismologist.

I dunno, but i'm gonna stick to USGS for now that's the 2nd stuff up i've seen on RSOE in the last 3 days.

yet another aftershock in haiti:

4.5 2010/01/13 12:28:26 18.409 -72.728 10.0 HAITI REGION

earthquake.usgs.gov...

And a 5.2 in Mindano, Philippines:

5.2 2010/01/13 12:42:39 6.647 124.353 10.0 MINDANAO, PHILIPPINES

earthquake.usgs.gov...

MAP 5.3 2010/01/13 14:43:45 18.395 -72.891 10.0 HAITI REGION

latest one in haiti, still getting aftershocks over 5.0 thats insane... 34 aftershocks since yesterdays 7.0
earthquake.usgs.gov...

I agree on the RSOE source, I've had issues with them before. Although, they do sometimes include quakes that don't necessarily ever appear on USGS maps because they don't come from one of the partner agencies (Canadian earthquakes for example don't appear on USGS maps at all unless they are above a certain magnitude.)

Also, and it's just a thread maintenance thing, but if we keep listing every 2.0 earthquake this thing will be 300 pages long by February. Let's keep it to major quakes except for specific events we are keeping tabs on, like Haiti aftershocks, or the continued activity in CA, or something associated with a specific volcano. Make sense?

Earth is rocking and rolling. Hopefully this one doesn't cause much damage but I bet if there was any, Sarah Pallin could see it from her house....

A few unusual spots in North America experiencing quakes this week.

and also earthquakes in Quebec:

A little bit about Quebec and seismic activity:

People in the large Western Quebec seismic zone have felt small earthquakes and suffered damage from larger ones for three centuries. The two largest damaging earthquakes occurred in 1935 (magnitude 6.1) at the northwestern end of the seismic zone, and in 1732 (magnitude 6.2) 450 km (280 mi) away at the southeastern end of the zone where it caused significant damage in Montreal. Earthquakes cause damage in the zone about once a decade. Smaller earthquakes are felt three or four times a year.

I also continue to see little bumps in the Long Valley region of CA.

UPDATE - 10 Earthquakes in the past hour.

Looks like 9 micro earthquakes in the past hour in Cali. I don't know much about geology, but is this normal? Foreshocks?

I'm in So. Cal and it feels like something significant is coming with these
vibrations that I keep getting from the type of chair I sit in. I don't
understand why I can feel these little vibs and I have felt 5 this morning.
So it seems we are on the same page somehow. Sounds completely
off the hook I know but here's the thing.
I think this freakin weird chair I'm in is picking up vibrations. Here's
why. This chair is metal framed. It has a round metal base, no wheels.
Where the desk and chair are in my Apt. there is no carpet. So what I
am sitting on is a flexible metal based frame sitting on a concrete foundation connected directly to the land mass. There is only 1 piece of
lanolium tile between the foundation and the chair. I usually get 2 or three of these vibs per month. Five this morning. Go figure.

Is that normal to have so many after shocks? Looks like they are all above 4.5 Scary stuff! too.reply to post by TheCoffinman

Hello Randyvs, It seems to me activity everywhere is up, I did notice the quakes in your state seem to be pickin up a bit. would you say so? I know people say it is a normal thing to feel allot of low movement, but doe it feel a bit greater than usual?
