I believe they had one close to Japan yesterday, too.

Earthquake in Chile shakes Lake Ponchartrain


Don Ames Reporting
Lake Ponchartrain was shaken and stirred early this morning by a massive earthquake in Chile.

"There was some sloshing of Lake Ponchartrain between about 4am and 4:30 this morning, our time. We had some, about half-a-foot slosh spikes near Shell Beach and that basically went on for about a half hour,' says Scott Lawrimore, with The Weather Channel.

Besides the Shell Beach area, the sloshing was also noticeable at Pass Manchac and West End in Metairie.

Lawrimore said the effect is like water being shaken in a bottle.

"The earthquake that occurred in the Pacific basically vibrated the earth enough here in Louisiana so that Lake Ponchartrain felt that...just like you would if you picked up a bucket of water and shook it back and forth," says Lawrimore.

"While that earthquake was occurring in the Pacific Ocean, even though it was not really detected by us, there was enough back and forth motion in the earth to produce sloshing back and forth in Lake Ponchartrain. And that sloshing resulted in about a half-a-foot slosh spike," Lawrimore said.

Tsunami warnings have been issued over a wide area, including South America, Hawaii, Australia and New Zealand, Japan, the Philippines, Russia and many Pacific islands.

People in Hawaii are being warned to take "urgent action to protect lives and property.'' The Pacific Tsunami Warning Center says the magnitude-8.8 earthquake in Chile has generated a tsunami that could cause damage along the coastlines of all the Hawaiian islands. There's even a possibility California and parts of Alaska could be affected.

At least 78 people have been killed in Chile.

I have a video that says the entire earth shook with the Sumatran Quake.

It would be interesting to have quake detection equipment.

Look around for local sites.  You can see their seismographs and when the waves hit their station.

I had to disconnect my accelerometer for the QCN because my computer wouldn't handle that plus the two weather stations and web cam.   :sad:

   On the USGS website they list a 5.2 quake today (27th) for Japan in the Ryukyu Islands.

tidal surges have been recorded in coastal areas in countries in the pacific from the Chile earthquake....with water receeding to low tide level and leaving fish stranded on the beach

Surge from wave going thru here now. Tide is falling(outgoing) but water level is coming up the beach.... Covering the rock pile I am using for reference point. So far it is about 1 -1 1/2 foot surge.

The world doesn't seem so big when you realize the distance that travelled and in that amount of time.

It's 1 hour 30 fligth Seattle to Ketchikan.  The wave surge going by the schedule they had  made was 1 hour fron lower 48/Candian border to my QTH.

Experts say that tsunamis travel between 400 to 500 MPH!
Wow! :shock:

I watched the live feeds from Hawaii while the "event" was underway.
Fortunately it was not severe.

   Impressive video!!  Even though it was a small tsunami wave it had some power in it.
I wouldn't want to be in one too much bigger than that.
   The link below is to the UniSci (International Science News) website.  There is a story about a tsunami wave that would result from an avalanche in the Canary Islands from an eruption of the Cumbra Vieja Volcano.  Scary stuff.

Read that too earlier.  Kind of like a trip to the chiropractor for the earth.
http://www.cnn.com/2010/WORLD/americas/03/02/chile.quake/index.html

The 2004 Indian ocean quake lengthened day by 6.8 microseconds.   So chile actually put us back on track a little.
The CNN piece even mentions that if China filled one of its resevoirs, the mass shift caused by the water would lengthen day by 0.06 microseconds

 :?:  Hmmm....I wonder if erupting volcanoes slow the rotation, kind of like putting a jet engine in full reverse?

    Go to http://www.Spaceweather.com to see a picture taken by an astronomer in Chili.  It shows stars wiggling around due to the earth shaking during an aftershock.
