5.6 quake shakes southern Greece

S greece quake
An earthquake with magnitude 5.6 occurred between the Peloponesse and the Cyclades in Greece at 6:44 am on Aug 28, 2014.

The epicenter was located beneath the seabed about 140 kilometers (86 miles) south of Athens and near the island of Milos.

There have been no reports of injuries or damages, however, the shock was widely felt in Athens and Crete.

The U.S. Geological Survey gave a preliminary magnitude of 5.6, while the Greek Institute of Geodynamicsr gave it as 5.7.

Comment: With the increase in volcanic and seismic activity around the world, this one is too close for comfort to the volcano of Thera (modern day Santorini).

Some San Francisco bay area residents report mysterious flashes in the sky during Napa quake


Several people called the KPIX 5 newsroom after Sunday morning's magnitude 6.0 earthquake in Napa, reporting mysterious flashes of light in the sky. Witnesses said the strange phenomenon looked like lightning.

Similar flashes of light have been reported in earthquakes around the world, from Japan to Peru.

Friedemann Freund, a scientist with the SETI Institute in Mountain View, said the same thing happened during Sunday morning's earthquake. And it wasn't a transformer blowing up or UFOs.

"What they are, are a consequence of the stresses building up deep below the earth, seven miles like in the case of the Napa Valley earthquake," Freund told KPIX 5.

He calls the phenomenon "earthquake lights," the quick buildup of stress that causes an electric current to flow to the surface and burst through the earth. This typically happens before or during an earthquake.

Sub-glacial eruption of Iceland's Bardarbunga volcano forms deep 'cauldrons' of melted ice

Icelandic volcano activity increased on Wednesday, with scientists detecting 10-15 meters deep cauldrons of melted ice at the Vatnajökull glacier, prompting fears of an imminent eruption.

A warning sign blocks the road to Bardarbunga volcano, some 20 kilometres (12.5 miles) away, in the north-west region of the Vatnajokull glacier August 19, 2014.
Icelandic scientists have detected a series of 10-15m deep cauldrons at Bardarbunga volcano glacier. They apparently are a result of melting following a sub-glacial eruption, the Icelandic Civil Protection Scientific Advisory Board reported. A surveillance flight over the surface of Vatnajokull has shown the cauldrons to be 1 km wide, located in a straight line some 4-6 kilometers south of the Bardarbunga caldera.

"The cauldrons have been formed as a result of melting, possibly a sub-glacial eruption, uncertain when," country's Meteorological Office said, pointing out that the data is still being analyzed.

"During the night (Wednesday) we have had three larger events, two of them in the Bardarbunga caldera. Those were 5.2 and 5.3, and very similar to the events that we have seen there before," Palmi Erlendsson, a geologist at the Met Office told the country's RTE news.

At the same time, scientists have registered more than 1,300 earthquakes since midnight Wednesday. Meanwhile 50km to the north, a 4.5 magnitude quake shook the Askja volcano, presumably because magma from Bardarbunga crater is traveling in that direction.

Persistently high methane concentrations show up over Beaufort Sea in the Arctic


High methane concentrations have been showing up over Beaufort Sea over the past few days, as shown on the image above. This follows the recent high methane concentrations over the East Siberian Sea.

The persistent character of these very high methane concentrations over the Arctic Ocean indicates that methane has started to erupt from clathrates under the seabed, triggered by very warm water reaching the bottom of the Arctic Ocean.


Comment: Perhaps the true trigger is seismic activity, which then also warms the water at the bottom of the ocean, see : Earthquakes, volcanic eruptions, sinkholes and flooding all in one: Iceland examines Bardarbunga volcano 'cauldrons'


Methane eruptions from hydrates in sediments under the Arctic Ocean helped mean methane levels reach new records, with mean global methane readings as high as 1835 parts per billion recorded at several altitudes on August 17, 2014.

Earthquakes, volcanic eruptions, sinkholes and flooding all in one: Iceland examines Bardarbunga volcano 'cauldrons'

barbarbunga cauldrons
Scientists in Iceland say they are examining several 'cauldrons' found near Bardarbunga volcano, which could potentially be a sign of an eruption.

The cauldrons, depressions in the volcano's surface, each between 10-15m (49 ft) deep and 1km (0.6 miles) wide, were seen during a flight on Wednesday.

Iceland's Met Office said they were formed "as a result of melting, possibly a sub-glacial eruption."

Bardarbunga volcano has been hit by several recent tremors.

The area experienced a magnitude 5.7 earthquake on Tuesday. Experts say these earthquakes are caused as magma flows beneath the ground, cracking the rocks as it moves.

The Met Office has kept its aviation warning level - indicating the potential threat of volcanic activity to air travel - at orange, its second-highest.

Iceland's Bardarbunga volcano: Magma moving towards new volcanic system

monitoring volcano

The University of Cambridge is monitoring the area with 70 seismometers
The magma from Iceland's Bardarbunga volcano could be moving towards another large volcanic system.

Data recorded by a team from the University of Cambridge suggests that 50 million cubic metres of molten rock has moved in the last 24 hours.

If it continues on a northern trajectory it could feed into the Askja volcanic system, potentially triggering a large eruption.

Prof Bob White said: "It's headed straight for it."

But he cautioned that volcanoes were hard to predict.

"It's moving at about 4km a day towards Askja, and if it keeps going it will get there in a few days," he told BBC News.

"We know there is a lot of molten rock sitting under the ground beneath Askja, which is a major volcanic system. If this molten rock hits that, we know it is likely to trigger it to erupt.

"But who knows, it may just stop. It is still at 5km-depth, and it is possible it could freeze there and not a lot more will happen. That is perfectly plausible."

August 24, 2014: 7.0 earthquake strikes Peru + 6.7 in Chile + 6.0 in California + Iceland erupting = major unrest occurring

earthquakes 24 august

Past 36 hours of earthquakes (up to 700pm CDT Aug. 24, 2014) shows a series of large events in South and North America. California having its first “destructive” earthquake in 25 years near San Francisco, Peru having a 7.0M event, and Chile having a 6.4M event.

Another large earthquake has struck the Pacific ring of fire.

On top of today's 6.0M in Central California, on top of yesterdays 6.7M earthquake in Chile, now we see a 6.8 magnitude (upgraded to 7.0M) event in Peru.

Overall, we are seeing a major uptick in earthquake activity occur. On top of Icelands large volcanic eruption, I would say now is a good time to have a plan and be prepared.

I'd still be watching near Vancouver Island. Salton Sea should show something soon as well. Notice the earthquakes stopped in Oklahoma temporarily.. the pressure has been "transferred" temporarily...

But to where? Where has the pressure transferred? Since we first saw the 6.7M yesterday in Chile.. now the 6.0M in California.. this makes me think its a NW pressure transfer which is occurring like all those deep asthenosphere earthquakes which were happening at the 350mile deep range.

Comment: Why is our Earth so seismically and volcanically active this summer? And don't forget that hundreds of methane plumes are erupting along the U.S. Atlantic coast! Things must be reaching a tipping point of sorts. Earth Changes and the Human Cosmic Connection has all the answers. A little spoiler: each one of us help create - or not - these conditions on our planet.

6.0 magnitude earthquake shakes San Francisco Bay Area

A damaged building in Napa, California, after an earthquake hit the San Francisco Bay Area on Sunday
An earthquake with a preliminary magnitude of 6.0 was reported early Sunday in California's northern San Francisco Bay Area.

Leslie Gordon of the United States Geological Survey said the tremor struck about 3:30 a.m. Sunday, about 10 miles northwest of American Canyon, which is about six miles southwest of Napa. The agency said it was the largest tremor to shake the Bay Area since the magnitude-6.9 Loma Prieta quake in 1989.

The agency said there was a "low likelihood for casualties," but issued an "orange alert" for possible damage, a rating that means "significant damage is likely and the disaster is potentially widespread."
