This area has been hit with several major aftershocks, over the last 24 hours. How much more will they have to endure? :cry:

U.S. Geological Survey, National Earthquake Information Center
World Data Center for Seismology, Denver

Aftershocks can go on for a significant amount of time.

After shocks even in the 8.0 category up to a month after woudl not be surprising

The Richter Scale is not linear: a level six event has only one thousandth the power of a level nine event....

BIG and destructive! So many people dying and Bushit is off biking. We expected the world and the moon and stars to stop when we lost 3000 people; but the Amurkin president doesn't blink an eye when thousands of others die . Where was the outpouring of sympathy for the thousands of French who died in the summer heat for instance. Do we really deep down think we're better.

At 9PM on January 26, 1700 one of the world's largest earthquakes occurred along the west coast of North America. The undersea Cascadia thrust fault ruptured along a 1000 km length, from mid Vancouver Island to northern California in a great earthquake, producing tremendous shaking and a huge tsunami that swept across the Pacific.

But at least 1000 km of fault line gave way.

Th island of Sumatra (CA size landmass) moved
approximately 60 m.

I feel for the people!!!

You're next...

and with junior in charge we will ahve to rely on ourselves.

the East coast is in more danger... Either way, it's not pleasant.

Ms. Tinoire is refering to recent publicity given the possibility of a catastrophic landside off of one of the Atlantic islands, though whether the Azores or the Canaries escapes my immediate recollection....

(though to be honest, I'd gotten a little muddled! Have been reading too much & too hastily these last couple of days)

:hi: & thanks!

US also faces tsunami threat (article)

Squatch had a thread about it here: http://www.democraticunderground.com/discuss/duboard.php?az=show_topic&forum=104&topic_id=2870152



US also faces tsunami threat


Paris - Cities on the US East Coast and in the Caribbean could be wrecked by a tsunami unleashed by the collapse of a volcanic island in the eastern Atlantic, British scientists believe.

A massive chunk of La Palma, the most volcanically active island in the Canaries archipelago, is unstable, says Simon Day, of the Benfield Grieg Hazard Research Centre at University College London.

He calculates that its flank could collapse the next time the volcano, Cumbre Vieja, erupts.

If so, that would send a dome-shaped wall of water up to 100 metres high racing across the Atlantic at 800 kilometres per hour, hitting the western coast of Africa and southern coast of England within a few hours.

Some eight hours after the collapse, the US East Coast and Caribbean would bear the brunt.

Cities from Miami to New York would get swamped by waves up to 50 metres high, capable of surging up to 20 kilometres inland, according to Day's research.

a huge chunk of land in Hawaii that is just hanging on? It's been mentioned on some Discovery Channel specials when they talk about quakes, tsunamis etc...

Thanks!

I believe you are referring to the Cumbre Vieja ridge in La Palma.


http://en.wikipedia.org/wiki/Cumbre_Vieja

I definitely remember Hawaii being mentioned, but I can't remember if it was the Big Island, or one of the others. I remember freaking out after reading about the one off the coast of Africa, thinking "WHAT? TWO possible island landslides??"

On further research, it IS also Hawaii:

http://www.science-frontiers.com/sf115/sf115p09.htm

"Worse waves may be on tap. A 4,760 cubic mile chunk of the Big Island (Hawaii) is breaking away at the rate of 4 inches per year. This is the Hilina Slump, and it is said to be "the most rapidly moving tract of ground on Earth for its size." The Hilina Slump can move much faster. At 4:48 AM, November 29, 1975, a 37-mile-wide section suddenly dropped 11½ feet and slid seaward 26 feet. The result was a magnitude-7.2 quake and a 48-foot-high tsunami. This was a minor of the slump. If the entire 4,760-cubic-mile block decided to break off, it would probably create a magnitude-9 quake and a tsunami 1,000-feet high. All the coast-hugging cities of the Hawaiian Islands would be swept away. And LOOK OUT Australia, Japan, and California."

double post

The Memphis fault is just as active as the San Andreas fault. It's just not as widely known as the famous California fault line. The region has been overdue for a good shake.

There is another fault that gave New York city a tremble fifteen years ago.

:evilgrin: That mean old Earthquake wouldn't dare challenge Governor Gropenator Action Hero!!


:hippie:

what determines when a quake is a FORE-shock or an AFTER-shock?

usually the strongest event is considered the main earthquake, all those who came afterwards are aftershocks.

in that region.

Compare this list:
http://www.gfz-potsdam.de/geofon/alerts /



with the one at USGS:
http://earthquake.usgs.gov/recenteqsww/Quakes/quakes_all.html

Can anyone explain the difference?

The recent earthquakes on the USGS are of a certain magnitude or higher the other may show smaller earthquakes.

than the USGS list. The USGS ">2.5" list shows a lot more small earthquakes within the US, but it does seem to miss some 5.x earthquakes in the Sumatra/Andaman/Nicobar region, and I was wondering about why that would be.

One school of thought holds that Mother Earth is raising her vibrational level and the process is resulting in a bunch of unpleasant side effects: hurricanes, floods, magnetic shifts, volcanic eruptions and, yes, earthquakes. Big, nasty ones.

A part of this theory holds that She is reacting to all the WRONG that is being, and has been, committed against rather large numbers of people in the last couple of decades. Some people believe that She has given the forces of negativity ample time to "come to the light" and now She intends to rise into Her new vibration and let "them" fend for themselves.

What if yesterday's "woo-woo" is tomorrow's reality? What if there is no "rational" explanation for all of this?

:freak:
dbt

Was an explanation I heard.

Fact remains that earthquakes are NORMAL. This planet is not here to accommodate us. It does not give a damn about us.

It's time we remembered that humans form nations and alliances to survive the PLANET which is not our friend.

Now, on a map of Malay Peninsula, Sumatera (Sumatra) Island
notice how the Strait of Malacca from Singapore
to Kuala Lumpur(it's port-Kelang could easily join up.

I think it was joined
and that Java Island was joined to Sumatera.

The recognition of definitive signatures in the geological
record tells us the January 26, 1700 event was not a
unique event, but has repeated many times at irregular
intervals of hundreds of years. Geological evidence
indicates that 13 great earthquakes have occurred in the
last 6000 years.

In the interval between great earthquakes, the tectonic
plates become stuck together, yet continue to move
towards each other. This causes tremendous strain
and deformation of the Earth's crust in the coastal region
and causes ongoing earthquake activity. This is the situation
that we are in now.

He has brought evil to this world; he is the anti-Christ whose people seek to bring Armageddon to pass. This is that work made manifest.

trying to save us from the anti-Christ. You advanced species are a wonder to us all - even us superior Vulcans.

The more significant the aftershock will increase fears of another tsumami. Readily appreciate these people's stress living in Califonia.

This should not qualify for LBN.
