EVALUATION

IT IS NOT KNOWN THAT A TSUNAMI WAS GENERATED. THIS WARNING IS
BASED ONLY ON THE EARTHQUAKE EVALUATION. AN EARTHQUAKE OF THIS
SIZE HAS THE POTENTIAL TO GENERATE A DESTRUCTIVE TSUNAMI THAT CAN
STRIKE COASTLINES IN THE REGION NEAR THE EPICENTER WITHIN MINUTES
TO HOURS. AUTHORITIES IN THE REGION SHOULD TAKE APPROPRIATE
ACTION IN RESPONSE TO THIS POSSIBILITY. THIS CENTER WILL MONITOR
SEA LEVEL GAUGES NEAREST THE REGION AND REPORT IF ANY TSUNAMI
WAVE ACTIVITY IS OBSERVED. THE WARNING WILL NOT EXPAND TO OTHER
AREAS OF THE PACIFIC UNLESS ADDITIONAL DATA ARE RECEIVED TO
WARRANT SUCH AN EXPANSION.

ESTIMATED INITIAL TSUNAMI WAVE ARRIVAL TIMES AT FORECAST POINTS
WITHIN THE WARNING AND WATCH AREAS ARE GIVEN BELOW. ACTUAL
ARRIVAL TIMES MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THE
LARGEST. A TSUNAMI IS A SERIES OF WAVES AND THE TIME BETWEEN
SUCCESSIVE WAVES CAN BE FIVE MINUTES TO ONE HOUR.

sorry....I saw the cancellation for caribbean also....still on for Costa Rica....

hope is a no go.

Was just down there for vacation about 3 months ago. The Costa Rica TV link above appears to be showing the epicenter is actually inland? I don't speak Spanish so maybe that's something else. There's an active volcano or two close by also. The area is where most of the major beach resorts are in that country. Further to the south there are lots of smaller villages with residents living practically on the beach. Even a moderate tsunami would be devastating.

Just a question..maybe someone can help me here.

If you go to this website.. quakes.globalincidentmap.com..... and zoom in, it shows 4 earthquakes. Two 7.6's and two 7.9's.

USGS website is only showing one 7.6.

From my experience, the first link will delete some of those eventually. Do they just mark every possibility or was there actually 4 earthquakes? Each one shows a different depth, which to me means 4 different quakes. It also has three different times for each quake.

Is it just me, or have things really been rocking and rolling lately?
7.6 is quite big for central america

usgs downgrade the magnitude i took an screenshoot when they were reporting the earthquake as 7.9 just in case

I done the same thing.
My guess would be that those are different measurement sites.
But i'm just guessing.

It looks like the quakes started at 20 miles deep and then proceeded down to 40 miles deep and then to 50 miles. So the top of the crust shook and then it moved deeper into the crust. Indication of large movement of mass.

Just my take.

reply to post by yospuig



Yea, this I know. But I'm asking about how many quakes there actually were. Why does globalincident show 4?

I ask because this happens every time there is a large earthquake. They show multiple quakes and hours later they get deleted. I'm not talking about downgrading the magnitude, I mean there are multiple earthquakes that get pushed down to one. Why do they report multiple ones?

You aint seen nothin yet.

News just reported it was 50 miles off shore...I think they said 25km deep?

Daughter was blah blah in my ear....so I think that's it.

I'm no expert in the matter, but it certainly appears to me that there has been a rise in seismic activity but I won't be offended if someone with more expertise on the matter corrects me. It seems the whole globe has been letting out a lot of stress recently.

That could be! I hadn't thought of that before, and I'm not sure how they get their data. I've learned in the past that they don't answer emails, so no use asking I guess.

reply to post by tport17


They get their info from several feeds. If you look at the feeds, just pick one. Usgs.gov is better when you want to narrow down info.

a rise in seismic activity

You never know,

www.abovetopsecret.com...

reply to post by Corruption Exposed


It's extremely evident to me that activity has increased just as it was stated that it would.
I have been monitoring activity for about 3 yrs and the last 2 weeks or so has been the most active i have seen.

Me either. Its just very strange how many EQ's Ive seen around the Indonesia and Australia area. And now, to me, it seems like more activity on the central america region. This may just be that i recently signed up for the EQ alert status via email, but maybe not......its all part of the ring of fire isnt it?

I think this earthquake is a foreshock to a 8.plus earthquake I am afraid to say...

think? or do you have any proof to think that might happen? just asking....curious...
