7.8 Earthquake Chile

Why have there been so many earthquakes in Chili lately?? What is going on down there!

small excerpt:

"But Tuesday night's quake was not the big one seismologists are expecting.

"Could be tomorrow, could be in 50 years; we do not know when it's going to occur. But the key point here is that this magnitude-8.2 is not the large earthquake that we were expecting for this area. We're actually still expecting potentially an even larger earthquake," said Mike Simons, a seismologist at the Geological Survey.

Chile is one of the world's most earthquake-prone countries because just off the coast, the Nazca tectonic plate plunges beneath the South American plate, pushing the towering Andes cordillera to ever-higher altitudes. Nowhere along this fault is the pressure greater than in far northern Chile, an area known as the "Iquique seismic gap".

The USGS says the seismic gap last saw a major quake in 1877, when a magnitude-8.8 quake hit. Another quake of similar force hit just north of the area in 1868

"This is the one remaining gap that hasn't had an earthquake in the last 140 years," said Simons. "We know these two plates come together at about 6, 7 centimeters a year, and if you multiply that by 140 years then the plates should have moved about 11 meters along the fault, and you can make an estimate of the size of earthquake we expect here."

Is it time to bring in the tomato plants?

whoops.....50 years ago.

Lots of earthquakes there its the ring of fire and one of the most active areas on the planet.

This one is going to be devastating for those near the epicenter... Really sad. These people need our prayers right now.

It looks like these guys on cnn are busting a nut, they got a lot of top stories to report lately

yes if it is close enough to the ocean

Alaska was also home to the worlds biggest tsunami...almost 1800 feet high. A guy and his son rode the whole wave in their boat up the side of a mountain.

any live news coverage?

No, not with all the smaller ones.

Omori's Law and Gutenberg–Richter law are getting gutted.

Mind you I haven't done the math, but at a glance, it doesn't add up.

:ohlook:

Off to the bar to watch the Mariners/Angels game. If LA goes, I'll see it live...

maybe.

Thoughts and prayers to everyone over there... how terrifying it would be

Again, he called this kind of quake activity for March/April on his twitter, it's been crazy….he has to be given credit: Thread: Numerologist's Predictions for 2014

They just had a 3.0 earthquake in Turkey!

A few details about the 2011 Japan earthquake...


The 9.0 magnitude (MW) undersea megathrust earthquake occurred on 11 March 2011 at 14:46 JST (05:46 UTC) in the north-western Pacific Ocean at a relatively shallow depth of 32 km (19.9 mi),[37] with its epicenter approximately 72 km (45 mi) east of the Oshika Peninsula of Tōhoku, Japan, lasting approximately six minutes.[1][2] The earthquake was initially reported as 7.9 MW by the USGS before it was quickly upgraded to 8.8 MW, then to 8.9 MW,[38] and then finally to 9.0 MW.[3][39] Sendai was the nearest major city to the earthquake, 130 km (81 mi) from the epicenter; the earthquake occurred 373 km (232 mi) from Tokyo.[2]

The main earthquake was preceded by a number of large foreshocks, with hundreds of aftershocks reported. The first major foreshock was a 7.2 MW event on 9 March, approximately 40 km (25 mi) from the epicenter of the 11 March earthquake, with another three on the same day in excess of 6.0 MW.[2][40] Following the main earthquake on 11 March, a 7.0 MW aftershock was reported at 15:06 JST (6:06 UTC), succeeded by a 7.4 MW at 15:15 JST (6:16 UTC) and a 7.2 MW at 15:26 JST (6:26 UTC).[41]

thats weird!!

now i realise that a 9 to 10 is coming soon... i hope not

Edit to say, the laws would still apply if you consider them separate events.

In summary, there are more small aftershocks and fewer large aftershocks.

According to that map it falls in the light to moderate damage range
