Philippines issues tsunami alert

"MANILA, Philippines - The government warned coastal communities on the eastern side of the archipelago Saturday to prepare for possible evacuation after a powerful earthquake in Chile triggered a tsunami.

The Philippine Institute of Volcanology and Seismology said that the 8.8-magnitude earthquake that struck in the Pacific Ocean near the coast of Chile early Saturday could generate a destructive tsunami that could hit coastlines on the western Pacific."

EVALUATION

A TSUNAMI HAS BEEN GENERATED THAT COULD CAUSE DAMAGE ALONG

COASTLINES OF ALL ISLANDS IN THE STATE OF HAWAII. URGENT ACTION

SHOULD BE TAKEN TO PROTECT LIVES AND PROPERTY.

A TSUNAMI IS A SERIES OF LONG OCEAN WAVES. EACH INDIVIDUAL WAVE

CREST CAN LAST 5 TO 15 MINUTES OR MORE AND EXTENSIVELY FLOOD

COASTAL AREAS. THE DANGER CAN CONTINUE FOR MANY HOURS AFTER THE

INITIAL WAVE AS SUBSEQUENT WAVES ARRIVE. TSUNAMI WAVE HEIGHTS

CANNOT BE PREDICTED AND THE FIRST WAVE MAY NOT BE THE LARGEST.

TSUNAMI WAVES EFFICIENTLY WRAP AROUND ISLANDS. ALL SHORES ARE AT

RISK NO MATTER WHICH DIRECTION THEY FACE. THE TROUGH OF A TSUNAMI

WAVE MAY TEMPORARILY EXPOSE THE SEAFLOOR BUT THE AREA WILL

QUICKLY FLOOD AGAIN. EXTREMELY STRONG AND UNUSUAL NEARSHORE

CURRENTS CAN ACCOMPANY A TSUNAMI. DEBRIS PICKED UP AND CARRIED

BY A TSUNAMI AMPLIFIES ITS DESTRUCTIVE POWER. SIMULTANEOUS HIGH

TIDES OR HIGH SURF CAN SIGNIFICANTLY INCREASE THE TSUNAMI HAZARD.

THE ESTIMATED ARRIVAL TIME IN HAWAII OF THE FIRST TSUNAMI WAVE IS

1119 AM HST SAT 27 FEB 2010

MESSAGES WILL BE ISSUED HOURLY OR SOONER AS CONDITIONS WARRANT.

Something is brewing here. Haiti, Japan, Chile, record snow fall on East coast of US - mother earth is angry.

I hope to hel_l this is just randomness messing with my head and all of this just happens to be going on right now - but seems far more likely that the earth is undergoing some kind of huge changes nobody understands yet. Could be global warming related, who knows - but I think the shit is about to hit the fan.

CNN reporting that local police says 40 meter waves hit the Juan Fernandez island. Police helicopter on the way to confirm.

I just HOPE thats not true! a 40m wave must be absolutely destructive :)

we got just 6m in Phuket when the tsunami striked here

Hope it wasn't 40..I read elsewhere it was about 3 metres..

Some information about what happens to Tsunami's as they approach land.

http://www.bom.gov.au/tsunami/tsunami_info.shtml#land

As a tsunami leaves the deep water of the open-ocean and travels into the shallower water near the coast, it transforms. If you read the "The physics of a tsunami" section, you will know that a tsunami travels at a speed that is related to the water depth - hence, as the water depth decreases, the tsunami slows. The tsunami's energy flux, which is dependent on both its wave speed and wave height, remains nearly constant. Consequently, as the tsunami's speed diminishes, its height grows. This is called shoaling. Because of this shoaling effect, a tsunami that is unnoticeable at sea, may grow to be several metres or more in height near the coast.

The increase of the tsunami's waveheight as it enters shallow water is given by:

shallow_height.gif where hs and hd are waveheights in shallow and deep water and Hs and Hd are the depths of the shallow and deep water. So a tsunami with a height of 1 m in the open ocean where the water depth is 4000m would have a waveheight of 4 to 5 m in water of depth 10 m.

Just like other water waves, tsunamis begin to lose energy as they rush onshore - part of the wave energy is reflected offshore, while the shoreward-propagating wave energy is dissipated through bottom friction and turbulence. Despite these losses, tsunamis still reach the coast with tremendous amounts of energy. Depending on whether the first part of the tsunami to reach the shore is a crest or a trough, it may appear as a rapidly rising or falling tide. Local bathymetry may also cause the tsunami to appear as a series of breaking waves.

Tsunamis have great erosion potential, stripping beaches of sand that may have taken years to accumulate and undermining trees and other coastal vegetation. Capable of inundating, or flooding, hundreds of metres inland past the typical high-water level, the fast-moving water associated with the inundating tsunami can crush homes and other coastal structures. Tsunamis may reach a maximum vertical height onshore above sea level, often called a run-up height, of tens of metres.

If its global warming related, how do you explain these Tsunamis between AD 365 and the late 1800's?

I live in kamala, Phuket and was here when the Tsunami hit in 2004. The roots of the trees along the beach were about 1 meter above the ground on the 27th.

The wave here rushed over 500 meters from the shore to the main road. In Koh Lak it pushed a navy boat over 800 meters inland!!

Theres some interesting reading here about tsunamis and the their effects on polar ice caps.

It is perhaps possible to effect the balance of the earth if a significant enough tsunami was to hit the north or south pole.

Update:

27th aftershock, magnitude 5.0, off shore of Chile - U.S. Geological Survey

White House: We are closely monitoring the situation, including the potential for a tsunami. Our thoughts and prayers are with the people of Chile, and we stand ready to help in this hour of need.

The media do say stupid things, don't they.

Earthquakes most certainly do kill people, not all people killed in earthquakes die under buildings. Wouldnt expect anything better from CNN. :)

one other major English newspaper refers even to Peru.

I would say not. Hilarious reading. The writer has forgotten the difference of the masses. The mass of ice is minimal compared to the mass of the earth. Therefore it should not have any effect, even if the mass is on top of the surface.

-Pekka

I read another article type thing on this some months ago & it was talking about the possiblity of a tsunami damaging ice, but i cant find it now, maybe for another time. Lots of speculation goes on with these types of things, some of it interesting though.

ps: I must point out that I personally know nothing very little about Tsunamis, just googling :)
