Earthquake in Sint Maarten / St Martin / SXM October 5 2009

Wow, here we are at anchor in St. Martin in the Simpson Bay Lagoon near Explorer Island and at about 12:30pm AST the boat started shaking.

What's that?  Are we dragging?  Is something pushing us?  What's that vibration? An explosion?  No "boom" so probably not... An earthquake?  Never felt an earthquake at anchor before.

Looked outside and everything is OK.  Our neighbor is also looking about, so obviously he felt it too.

Called the radio station (Island 92) and he said that their building (FedEx) was shaking. At 12:52pm the radio station had to go on generator power as GEBE must have gone down.

Nothing on the internet yet...

12:58pm AST

Just found this: http://mesonet.agron.iastate.edu/p.php?pid=200910051651-TJSJ-SECA62-EQRSJU

(which appears to be inaccurate as reports lower down says it was EAST of St Martin....)

Odd map... That's not SW of St Thomas... That's southEAST and right on top of St Martin!

So what's up???


1:19pm AST
I think that first report, mentioned above, from San Juan Puerto Rico made a typo when they said southWEST...
This site http://earthquake.usgs.gov/eqcenter/recenteqsww/Quakes/us2009mjbi.php
lists it as being 18.043°N, 62.781°W and
29 km (18 miles) ESE (102°) from Marigot, Saint Martin, Guadeloupe
30 km (18 miles) E (87°) from Philipsburg, Sint Maarten, Netherlands Antilles

That's more like it :)

Hopefully we won't get tsunami... Kick 'em Jenny???
