140+ quakes in 6 days!! NE of Puerto Rico,U.S.VI,BVI

[Aslkahuna]

There's not much anyone can do about an earthquake except hope that a big one doesn't occur. Unlike hurricanes, earthquake preparation requires a lot of long term work such as retrofitting buildings, etc. At any rate, mags 2 and 3 earthquakes are not significant unless they can clearly be shown as magmatic and near surface shocks around an active volcano and if they were eruption precursors they would be showing up in far greater numbers.

Nothing felt by me nor the majority of the population in this period of acticity as the quakes mainly are very low in magnitud.The goverment since the last 5 years has been working on a campain of orientation to the public about what to do in case of a big one.Also they have a commision about earthquakes by the agencys that are of emergencys here such as the Emergency Management,Health department,Departement of Education and others.

It will eventually happen, of course. I mean, Lisbon doesn't even sit on any active faultlines, so it's not like the Atlantic is immune...I suppose after it happens, then buildings will be retrofitted in Puerto Rico. (despite the fact that there likely won't be another major earthquake for centuries there)

Wow!
what is going on?
St. Maarten felt one of those on Thursday evening.
I haven't heard any reports here on the island that any more tremors were experienced since then though.

Here's a link to a map of faults of NE Carib Region.

The legend is on the bottom far right. Are these earthquakes shallow?

Hopefully its a big island at least the size of PR forming!

Even if there was an island forming... you would never live to see it... nor would your children, grandchildren, or anyone in your family for the next several thousand years (at least).

I am not to sure about the depth of the waters here and you are basically 100 % correct about what you said but the birth of Paricutin showed the geology world that everything that we had previously assumed is not always fact. There can be minor exceptions.

The Paricutin volcano grew out of a corn field, in Mexico , in 1943. The farmer had occasionally been noticing heat and steam from a certain part of his farm but he never really paid much attention to it. A short time later he had a volcano growing in his field. The height of cone was a little over 1,000 feet one year later. It never did grow that much after this but it continued to be active for about another eight years.

[JonathanBelles]

it grew 1000 ft in one year?

[Audrey2Katrina]

it grew 1000 ft in one year?

If I remember my geology courses well enough, it grew some 150 ft in the first 24 hours or so after it began to develop its cone--some 1100 ft in the first year, and went dormant about 10 years later...about 1300-1400 ft. high.

Ahh... yes. I remember learning about that in school when I was really young. Very unique event.

Yes it was quite unique. At least from what little time modern man has spent on this planet.

A2K - Your numbers sound right and it is dormant.

Fact789 -Yep it grew rather quick. It would have been quite a thing to witness. Anyobdy who likes earth sciences could appreciate what was happening.

thats unreal, not tusnami producers I hope

[Tampa Bay Hurricane]

Earthquakes sound very scary. At least you can many times run from a hurricane but earthquakes, like tornadoes, hit with little warning.

[Aslkahuna]

Incidentally, I would like to point out that April 18th will be the 100th Anniversary of the Northern California Earthquake of 1906. With a surface magnitude of 7.7 and a moment magnitude of 7.9 te shock and subsequent fire destroyed 80% of San Francisco and roughed up the other towns in the area. Modern estimates are that 3000 were killed, 225000 left homeless out of a population of 400000 and total damage was 400 million 1906 dollars. It also remains one of the most important earthquake events scientifically.

Earthquakes have no warning at all

The Tangshan Quake of 1976 was said of of killed over 240,000 when with a magnitude of 7.8 struck at 3am in ther morning.

Look up to link. The string of quakes has continued.But all haved been minor quakes that not cause harm.

[MiamiensisWx]

Wow!

[Jim Cantore]

now 140?? what causes that?

Earthquakes are more dangerous then Hurricanes for 1 reason

they strike without warning

205 seismos found since Feb. 24, 2006. http://temblor.uprm.edu/cgi-bin/new-search.cgi
There is an article about the last unusual swarm that occured in 2001 that produced ovee 100 earthquakes -
