Yes, over here on VG it was light but went on a good while which caused concern.

I saw a string of 11 tremors on my USGS alerts last night. I just checked USGS and see a 4.6 magnitude just popped off. Big one! Good luck.

Cheers, RickG

Shook us here on Nail Bay. First I've felt.
Rumble on the beach, husband said windows rattled in the house.
4.6 according to http://earthquake-report.com/2012/02/11/caribbean-region-real-time-earthquakes-list/

well... I was gonna say... tsunami won't affect most of us on Tortola
but.... Anegada could get a bit wet...what is the highest point? 24 feet above sea ?
Manpot could get a bit damp also

Well that explains everything! Anchored in Christmas Cove and got woken up in the wee hours - boat is being tossed around like a cork. Bam! Bam! Holy ... thought I was being attached by a whale or something!

Nobody panic. There is no Tsunami warning. <img src="http://www.traveltalkonline.com/forums/images/graemlins/Joy.gif" alt="" />

NOAA Clearly states at the link above:
* There is NO tsunami danger from this earthquake. Issued at: 3/20/2015, 7:21:42 AM

All these years I've wanted to feel one and we must have been in the boat coming into Trellis Bay! Wonder if we'll find any damage when we get back home.

Sounds like a ferry wake.
In a earthquake your boat will feel like something jolted it.

Very shallow.

Here's a website that monitors Earthquakes around the world and will text your cell phone if a tsunami warning has been issued for your area

Re: Nice little earthquake - 03/20/2015 09:57 PM

Jolted is correct! Thought I run aground, been hit by another boat or getting humped by an amorous whale or something smile

4.6 "big one" Nah! <img src="http://www.traveltalkonline.com/forums/images/graemlins/Wink.gif" alt="" />

Re: Nice little earthquake - 03/20/2015 11:25 PM

Of course not especially by California standards but hey it was my first at sea so I'm no longer an earthquake virgin I guess?

Live on the New Madrid fault where if 1811and 12 were today would likely be the worst disaster ever to befall the U.S. .. Huge area was involved..fish on two Huge lakes that were created overnight in S. Illinois and West Tennessee ... the Mississipi river near my house ran backwards for a good while and today every bridge and masonry building between St Louis and Memphis would be gone. A 4.9 ..though the duration was a bit disconcerting was not anything to worry bout. One shower..and then a magnificent day.

I would worry more about Will who is dead center of the New Madrid than I would Manpot. OTOH Thurston will have premium seats at South Sound available for the next BVI tsunami. <img src="http://www.traveltalkonline.com/forums/images/graemlins/Grin.gif" alt="" />

Glenn, what would it have looked like on the water?

Re: Nice little earthquake - 03/21/2015 12:06 PM

If the volcano in Montserrate blows out the N west side of the mountain we will have a tsunami on the south side of the VI's and PR in twenty minutes or so.

Re: Nice little earthquake - 03/21/2015 12:33 PM

Now that would be intersting ( heard there had already been insurance gurus looking at potential damage in RT). I wonder how far that would wrap around and affect the north shore??

Re: Nice little earthquake - 03/21/2015 12:39 PM

Considering the sizes of the Islands I would imagine the seas would wrap around all of them except PR

Re: Nice little earthquake - 03/21/2015 12:50 PM

My money is on a major break in the bottom of the Anegada Trough sending a big wave in from the east. If you consider the Virgin Island/Puerto Rico microplate as fixed, the Atlantic Ocean is moving west on the other side of the north drop by about half an inch a year and St. Martin is moving east at about one inch a year. Lots of little quakes like this one mean that the north fault is moving along nicely but there has been almost no significant activity to the east in almost 150 years.

Normaly you would not be aware of an earthquake on a boat. At anchor you might hear a low rumble transmitted up the anchor chain. However, there is an effect called a seismic seiche or slosh that can occur in certain conditions in an inclosed body of water. I don't think Christmas Cove would qualify but the Bight might.

Re: Nice little earthquake - 03/21/2015 01:05 PM

Well the deepest part of the Atlantic Ocean is the PR trench which is actually a fault line, if it were to have a quake large enough to cause it to collapse half of PR would slide into the sea.
As for feeling the effects of an earthquake at anchor my experience has been once in Trellis Bay and once in the Marina Puerto del Rey, both are pretty much enclosed.
