Earthquakes Hit Alaska's Aleutian Island and New Zealand

A NewsTalkers Article

CNN has reported earthquakes in the Aleutian Islands in the North Pacific near the Bering Sea, and in the South Pacific Ocean southeast ofRaoul Island near New Zealand, occurring less than 24 hours apart. I'm no seismologists, but the fact that thequakes are almost perpendicular with the earths axis and occurred so close together in time, seems to me like more than a coincidence.

A tsunami advisory had been issued for coastal Alaskaafter the magnitude 7.9 earthquake struck Monday about 15 miles from Little Sitkin Island. The town of Adak had evacuated its 150 residents to a shelter about 600 feet above sea level after the initial tsunami warning, City Manager Layton Lockett told CNN.However the advisory waS later canceled.

There were no initial reports of quake damage in Adak or on Shemya Island, said Ian Dickson, website manager for the Alaska Earthquake Information Center.

Dickson said there were 17 measurable aftershocks in the two hours after the quake.

First estimates put the quake, which had a depth of 71 milesaccording to seismologists, was initially measured at a magnitude of 8.0, was subsequently set by the U.S. Geological Survey at 7.9 magnitude.

Almost simultaneously CNN reported a trio of earthquakes had struck in the South Pacific Ocean Tuesday morningsoutheast of Raoul Island, New Zealand, theU.S. Geological Survey said. Also, as in the Alaska quake, th ere were no immediate reports of damage.

In the South Pacific, two quakes, with magnitudes of 6.9 and 6.3, hit within minutes of each other, according to USGS data. The larger of the two was originally reported by the USGS to be a 7.2-magnitude, but that measure was later downgraded to 6.9.

A third, 6.2-magnitude quake struck about 45 minutes later.

The quakes hit near the eastern edge of the Australian tectonic plate, one of the most active seismic regions in the world, according to the USGS.

The South Pacific quakes all a depth of about 12 miles, and happened about 50 miles southeast of Raoul Island.

I'm really, really glad I don't live on the west coast! I live tucked away in the North East corner of this great country, in a haven known as the Adirondack Mountains a/k/a "Gods Country", where earthquakes, tornados, wildfires, floods and other natural disasters fear to tread.

(Now watch the epic center of a 8.2 mag earthquake occur directly under my house, then it will rain for two days at an inch an hour, causing the banks of Loon Lake to overflow, washing the remains of my house clear into town, where it will be picked up by a tornado and dropped somewhere in Canada.)

USGS Scientist Says Alaska, New Zealand Quakes Might Be Linked

SAN FRANCISCO (KCBS) With massive quakes striking off the Alaskan and New Zealand coast Monday, a scientist with the U.S. Geological Survey said he is weighing the possibilities that the two might be connected.

David Oppenheimer of the USGS told KCBS that there are several times a year when large earthquakes across the world occur within minutes of each other.

Oppenheimer said it is possible the New Zealand quake triggered the Alaska quake.

Did I say it?!

"I'm no seismologists, but the fact that the quakes are almost perpendicular with the earths axis and occurred so close together in time, seems to me like more than a coincidence."

I said it !!

Read the layers of the tectonic plates, their depth, and positioning on the overall core. I don't have the USGS ARCView, so I can't get a read - but, it does sound as though there "may" be some connections.

7.9 is extreme enough to do a lot of damage. How lucky they are!

But at least there won't be a forest fire. Nothing left that's dry enough to burn.

Give it time and it will be blamed on Global warming.

You're too late. Scientist have been examining the link between the increasedseismic activity and global warming for some time now.

Warming May Trigger Greater Seismic Activity

[ WorldWatch Institute ] Excerpt; " The melting of glaciers driven by global warming portends a seismically turbulent future. When glaciers melt, the massive weight on the Earth's crust is reduced, and the crust bounces back in what scientists call an "isostatic rebound. This process can reactivate faults, increase seismic activity, and lift pressure on magma chambers that feed volcanoes."

"This has happened several times throughout Earth's history, and the evidence suggests that it is starting to happen again. Of course, not every volcanic eruption and earthquake in the years to come will have a climate-change link. "

Is there really anything that naturally occurs that you guys can't blame on global warming?

"... naturally occurs...?" What do you mean by naturally occurs? Are you implying that if anoccurrenceontheearth is caused by 'natrual' changes of nature, we should pay no attention to it?

When we build structures in areas prone to earthquakes we build them to better withstand those earthquakes, when webuildstructures in areas prone to hurricanes andcyclones, we build them so they are better able to withstand high winds, we alwaysadaptto the climate conditions wherever we go.

Right now we areexperiencing changes in the weather patterns due to the warming of the planet, and yes, this has happened before, the earth goes through what many call 'natural' cycles. bringing on Ice ages every 50,000 years or so. But THIS time is different.

The planet is over 4.5 BILLION years old, people have only been around for 200 thousand years. When the last ice age peaked a mere 15,000 years ago, there were about 5 million people on the planet, but as the earth goes through its current 'natural' cycle it has to take with it the 7, soon to be 9, BILLION people living here. THAT has never happened before.

Would common sense not dictate those 7 BILLION people are having some effect on what is to be considered 'naturaloccurrences' in the earths climate cycle?

So yeah, many most things that occur within the environment can be linked tothewarning of the planet in some way.

Except for your flat tire, that's not a 'naturaloccurrence", unless of course you're wearing your good suit and on your way to an important meeting.

I guess if you spin something enough times eventually you will find an explanationthat fits the agenda.

Right Wingers are often accused of not being able to deal with or accept facts, even when they are put right in front of them.

I posted a comment above containing a fairly well linked and documented scientific report pertaining to this discussion, and all you do is call it "spin". Nice going Mike, you have provided a perfect example to support the argument you guys are not able, can't, won't, don't want to deal with facts!
