That puts it near Guantanamo

Interesting that even experts seem to be interested in the unusually high concentration in the area This is from a few days back

I have been watching the Puerto Rico area earthquakes. There have been many of them. Perhaps Haiti started a shift and now the pressure is building toward the east all along the fault boundry. I think I read that small quakes are really harbingers of larger ones? If so, then it maybe the area north of PR that is in for trouble.

Does anyone know approximately how long it would take for a P wave to travel 1,100 Km?

There is a quake on the MGOD.AV..EHZ.2010.079 plot yesterday at approx 17:22 UTC and I am wondering if this is the quake mag 1.9 at 17:18 in Southern Alaska, or is that too long to travel that distance?

MGOD.AV by the way (if you have been on the Yellowstone thread) is "God's own repeater site" - it's description in the IRIS DMC database.

WHAT? r u serious?

Also, you'd be lucky to pickup a 1.9 at 500 km away, on a good day. 1,100 km away is absolutely out of the question for a 1.9, Not strong enough. At least out west. A typical example of this would be the Yellowstone/California distance relationship: we have 3.5's all the time in CA, and they are never picked up at Yellowstone, roughly 800 miles away.

In the east, because of the different geologic composition, things will be a bit different, as you probably know. But even then I question if you could pickup a 1.9- 1,100 km away.

Perhaps this would be a more suitable candidate.

although the amplitude seems low for a 5.1 that close.

Well I did think that was the case. but you know you have to ask.

reply to post by EngTech36


That 5.1 I did not spot for some reason.

I guess that has to be it. Maybe the sensitivity is turned down low (or high depending on how you look at it)

Do you guys also accept volcano eruptions in this thread :-P

Iceland Volcano Erupting

REYKJAVIK, ICELAND—A volcano erupted near a glacier in southern Iceland, shooting ash and molten lava into the air and forcing the evacuation Sunday of hundreds of people from nearby villages. There were no immediate reports of injuries or damage from the Eyjafjallajokull volcano, but a state of emergency was declared and scientists feared the eruption could trigger a larger and potentially more dangerous eruption at the Katla volcano.
