That's probably an under-estimate Rog. It's already up to 6000 now. Sad

Yeah Ka, 3m/10sec is warp speed for a ground movement! Shocked

Its impossible to say what the toll will be Rock, many areas are still totally cut off and quite remote.

It is impossible to say Rog. There are many small villages that are so remote it will take a while to get to them.

Tibet got whacked too.

The toll in Nepal is 6500 and climbing! Sad

Big 'Quake off the coast of Papua New Guinea too. 7.1R and an aftershock of 6.9R.

Oh! Oh oh oh... there's an undersea volcano erupting off the Oregon coast (US west coast). I'll look for the article again. More Ring of Fire activity...

The Pacific is heating up volcanically and climatically Ka!

This planet is a living organism.

http://hisz.rsoe.hu/alertmap/site/index.php?pageid=event_summary&edis_code=UGE-20150501-48017-OTH[/mention] wrote:Axial Seamount, a volcano under the Pacific Ocean about 300 miles off the Oregon coast, appears to be erupting, according to two geologists who predicted the event would happen this year. Researchers said an eruption would not be a threat to coastal residents. The earthquakes at Axial Seamount are small, and the seafloor movements gradual and thus cannot cause a tsunami. Bill Chadwick of Oregon State University and Scott Nooner of the University of North Carolina Wilmington first made their prediction in September. It was based on previous research that showed how the volcano inflates and deflates like a balloon in a repeatable pattern as it responds to magma being fed into the seamount. Since last Friday, the region has experienced thousands of tiny earthquakes - a sign that magma is moving toward the surface - and the seafloor dropped nearly 8 feet, also a sign of magma being withdrawn from a reservoir under the seamount. William Wilcock of the University of Washington first observed the earthquakes on instruments. Chadwick, who works out of Oregon State's Hatfield Marine Science Center in Newport, said it isn't clear whether there is a full-blown volcanic eruption or if it is a large movement of magma that hasn't quite reached the sea floor. "There are some hints that lava did erupt, but we may not know for sure until we can get out there with a ship," he says in a press release announcing the findings. Axial Seamount last erupted in 2011, and that event was loosely forecast by Chadwick and Nooner, who had said in 2006 that the volcano would erupt before 2014.

and an update

http://hisz.rsoe.hu/alertmap/site/index.php?pageid=event_update_read&edis_id=UGE-20150501-48017-OTH&uid=16123[/mention] wrote:Scientists believe an underwater volcano may be erupting off the Oregon coast after a string of thousands of small earthquakes started occurring last Friday. The quakes were registered in the region Axial Seamont, a volcano about 300 miles out to sea from Cannon Beach, Oregon. Researchers say the quakes are a sign that magma is moving to the surface. They've also observed that the seafloor has dropped by nearly 8 feet-another sign that something may be going on. Two geologists, Bill Chadwick of Oregon State University and Scott Nooner of the University of North Carolina Wilmington, predicted last September that Axial would erupt and now believe they are right. However, they won't be able to confirm what's happening until they get out there to see first hand. "It isn't clear yet whether the earthquakes and deflation at Axial are related to a full-blown eruption, or if it is only a large intrusion of magma that hasn't quite reached the surface," said Chadwick, in a press release from Oregon State. "There are some hints that lava did erupt, but we may not know for sure until we can get out there with a ship."


And I did see a depression occur south of the volcano

Plenty of volcanic vents seen on the floor of the Pascific sitting dormant, I also note that there are several eruptions in Mexico and South America marked as well.

Four 7+ mags in PNG through this last week. Wonder what effect that will have on shifting the load to other parts of that fault.

Magnitude 8.5 earthquake hits off Japan, shakes buildings in Tokyo
2 HOURS AGO MAY 30, 2015 9:42PM

A POWERFUL earthquake which struck off the coast of Japan on Saturday night shook buildings in Tokyo and was felt across most of the country.

The magnitude 8.5 quake struck at 8.30pm (9.30pm AEST) 874km from Tokyo in the northern Pacific.

Residential buildings swayed for around a minute as the quake built in intensity at around 8.30pm (9.30pm AEST).

The Pacific Tsunami Warning Centre, which said the earthquake had a magnitude of 8.5, was at a depth of 696 kilometres.

The Japan Meteorological Bureau said there was no threat of a tsunami.

The quake follows a day after a volcano exploded into life in Japan’s southern islands, forcing the evacuation of villagers.

Japan vigilant for 'Big One' after powerful quake

AFP
May 31, 2015, 6:37 pm

Tokyo (AFP) - Seismologists Sunday warned Japan to stay vigilant for the next "Big One" after a powerful 7.8-magnitude earthquake struck off the coast of the quake-prone nation, injuring a dozen people.

Buildings swayed for around a minute in Tokyo and its vicinity Saturday night as the quake struck at a remote spot in the Pacific Ocean 874 kilometres (542 miles) south of the capital, the US Geological Survey said.

Despite its power, there was no risk of a tsunami as its epicentre was a deep 676 kilometres below the Earth's surface, the USGS and the Pacific Tsunami Warning Center said.

Twelve people were injured, including a 56-year-old man who broke his ribs, but no one was killed, an official of the Tokyo Fire Department and local media said Sunday.

Some 400 people were trapped on the observation decks of Tokyo Tower as its elevators stopped for more than one hour.

Runways at Haneda Airport in Tokyo were closed for about 30 minutes, with trains also temporarily halted, while a football match in the city was briefly suspended.

There were no reported problems at any of the region's mothballed nuclear power plants.

A separate 6.2-magnitude quake hit Sunday morning off the Izu Islands south of Tokyo, the USGS said, but there were no reports of damage or injuries.

Saturday's quake was the second sizeable tremor Tokyo has experienced in a week, after a much less powerful -- but far shallower -- earthquake close to the capital on Monday.

Some experts warn recent quakes and volcano eruptions may be signs that areas near the country are entering an active phase of crustal changes.

"I can say Japan is in an active stage now," said Toshiyasu Nagao, head of Earthquake Prediction Research Centre at Tokai University.

"Considering the geographic location of Japan, we can say the current activities are rather normal and it was too quiet" before the 2011 jolt, Nagao told AFP.

"We should be vigilant by knowing that it is no wonder that an earthquake sizeable enough to affect our society can occur anytime in the future," he said.

On Friday a volcano in the far south of Japan erupted, spewing a huge column of ash high into the sky and forcing authorities to evacuate the island on which it sits.

The eruption caused no injuries and no damage was reported, but it was another reminder of the country's volatile geology.
