Huge earthquake near Santiago and Concepcion in Chile. News is sparse at the moment but it's rated at 8.8 depending on the source. That's huge. To put it in perspective, that's several hundred times as powerful as the recent Haiti earthquake. I haven't seen many reports yet of what exactly is happening Santiago at the moment, but it seems the earthquake was deep (35 km below the surface), which would have lessened the impact. Also, the epicentre was further from densely populated areas.

BBC News - Massive earthquake strikes Chile

There are tsunami warnings for Chile, Peru, Colombia, Panama, Costa Rica, Ecuador, and Antarctica. I'm in Hawaii right now, but there is a only a (much less critical) tsunami advisory for here.

---

Apparently it was actually deeper. Other sites are reporting a depth of 37 miles, or 59 km.

CBC News - Massive earthquake hits Chile

Power is out and phones lines are down, but most of the damage is supposedly minor. Hard to verify reports though, since communications are partly down.

6 dead so far

Depth was in fact 35 km, or 22 miles, according to Reuters.

7th most powerful of all time

Before the Feb. 26 quake, these were the top 10 quakes of all time:

1. 1960 – Chile – M 9.5
2. 1964 – Prince William Sound, Alaska – M 9.2
3. 2004 – Sumatra-Andaman Islands – M 9.1
4. 1952 – Kamchatka – M 9.0
5. 1868 – Arica, Peru (now Chile) – M 9.0
6. 1700 – Cascadia Subduction Zone – M 9.0
7. 1906 – Off the Coast of Esmeraldas, Ecuador – M 8.8
8. 1965 – Rat Islands, Alaska – M 8.7
9. 1755 – Lisbon, Portugal – M 8.7
10. 1730 – Valparasio, Chile – M 8.7

The Jan. 12, 2010 earthquake in Haiti was rated at magnitude 7.0 and does not even figure in the Top 100 most powerful quakes of all time.

You see, the increased hot air in the atmosphere has the capacity to hold more moisture, which is causing the massive snowfalls throughout the county. The imbalance in weight by all the tons of snow in the north is putting the Earth's crust at risk of being bent because there's no snow in the southern hemisphere to counteract the weight of the snow in the north. This is causing all these massive earthquakes.

On a more serious note, I saw a show on Discovery about them building a huge dam near there. Was that ever completed? It was in Chile, but not sure how far from the earthquake it was.

That was a different area.

I don't mean to sound disrespectful, but in light of Chile's history, this isn't a huge quake for them. They've had quakes over 9.0, up to the 9.5 range, which is simply astounding to consider.

These are caused by AGW, right?

This is the 7th largest earthquake in human recorded history, and #3 for Chile.

We left for the highway before the first alarm siren even sounded. The highways are above the tsunami line. After breakfast we went to the top of a cliff to watch the waves come in, but they didn't. Well, they did apparently, up to 3.5 feet only, but I didn't see them.

All I know is the Hawaii radio DJs are very laid back. I did hear a call in show where some woman living upland was worried the evacuees would pee on the uplanders' roads or whatever.

You'll still need a podium that fits 700+ on third place, jerk.

Chile quake shortened our days, NASA says - thestar.com

“The length of the day should have gotten shorter by 1.26 microseconds (millionths of a second),” Gross, said Monday in an e-mailed reply to questions. “The axis about which the Earth’s mass is balanced should have moved by 2.7 milliarcseconds (about 8 centimetres or 3 inches).”

The changes can be modeled, though they’re difficult to physically detect given their small size, Gross said. Some changes may be more obvious, and islands may have shifted, according to Andreas Rietbrock, a professor of Earth Sciences at Britain’s Liverpool University who has studied the area impacted, though not since the latest temblor.

Santa Maria Island off the coast near Concepcion, Chile’s second-largest city, may have been raised 6 feet as a result of the latest quake, Rietbrock said Monday in a telephone interview. He said the rocks there show evidence pointing to past earthquakes shifting the island upward in the past.

“It’s what we call the ice-skater effect,” David Kerridge, head of Earth hazards and systems at the British Geological Survey in Edinburgh, said Monday in a telephone interview. “As the ice skater puts when she’s going around in a circle, and she pulls her arms in, she gets faster and faster. It’s the same idea with the Earth going around if you change the distribution of mass, the rotation rate changes.”

It speaks volumes (though I’m not sure as to what, exactly) that a quake of this magnitude has a death toll of only (‘only’) just around 750 people have died. Considering that the Haiti quake was only around 7.0, and yet killed several hundred thousand people (or that the Great Shaanxi Earthquake was only about an 8.0 and still managed to kill about 830,000 people!), the Chileans must be doing something right against earthquakes.
