Volcano in Chile shows signs of eruption

Eruptions of smoke and ash from Chile's Chaiten renew fears among population. Chile's Chaiten volcano spews smoke and ash, renewing fears of residents and authorities who witnessed massive eruptions from the volcano in May.

After several weeks of relative calm, Chile's Chaiten volcano, groaned and rumbled on Thursday (July 31), shooting out ash and causing renewed fears among residents and authorities. Regional director of the National Geological and Mine Service, Jorge Munoz, said that the volcano had registered 105 tremors, many with relatively strong intensity coming in at roughly 4.0 on the Richter scale. "Well, there are two scenarios," said Munoz after surveying Chaiten from the air. "One scenario is very concrete - it is that the eruption is ending, the first cycle of the eruption is ending and we can in relation with the high seismic activity that we currently have, have the probability in a hypothesis that a second cycle could begin."


Dark clouds again blankets Mt Anak Krakatau

Serang, Banten, (ANTARA News) - Dark clouds again blanketed Mount Anak Krakatau on Sunday, making vulconological officers unable to visually monitor its activities."Since the past three months, the volcano`s activities have not been clearly visible as dark clouds are blanketing it," Andi, an officer in charge of monitoring the volcano`s activities, said on Sunday.

Federal workers ask to leave volcanic island

ADAK -- Two U.S. Fish and Wildlife Service employees requested to be evacuated from Kasatochi Island in the Aleutians after seismic activity in the area, according to the U.S. Coast Guard.

The island, about 50 miles east of Adak, was reportedly experiencing tremors and volcanic uncertainty, which prompted the Alaska Volcano Observatory to issue an advisory in the area.

Kasatochi volcano erupts in Aleutians

The Alaska Volcano Observatory has issued a red alert for planes flying near the Kasatochi volcano in the Aleutian islands after a major eruption Thursday sent ash plume 45,000 feet into the air.

The 2-square-mile Kasatochi island about 50 miles west of Adak is uninhabited.

Kasatochi is one of three Aleutian volcanos currently erupting. Okmok began erupting July 12. Mount Cleveland erupted July 21.

Newly Named Peralta Hills Fault Blamed for Tuesday’s Quake

CHINO HILLS -- Scientists analyzing reams of data generated by last week's 5.4 magnitude earthquake have pinpointed the epicenter and given Californians a new fault to worry about, it was reported today.

The Peralta Hills Fault is believed to be the stress point that gave way at 11:42 a.m. Tuesday, rattling silverware from Las Vegas to Tijuana, the San Gabriel Valley Tribune reported.
...
The Peralta Hills Fault is capable of a a 6.5 magnitude quake, but the Whittier and Chino faults could generate a 7.5 quake, Fife said. Because the magnitude scale is a logarithmic measurement, that 7.5 potential quake would be about 1,448 times more powerful than Tuesday's little shaker.



Deadly San Andreas Fault Longer Than Thought

Tuesday's magnitude 5.4 quake in greater Los Angeles occurred along one of many lesser known fault lines that fan out from the San Andreas like glass fractures.

The new finding, meanwhile, adds 18 miles (30 kilometers) of earthquake potential to the deadly major fault that devastated San Francisco and Loma Prieta in 1906 and 1989, respectively.

A scientist discovered the San Andreas Fault was longer while he was studying boiling pools of mud called mud pots and small, erupting mud volcanoes near the Salton Sea (learn more), a saltwater lake about 165 miles (265 kilometers) southeast of Los Angeles.




California not ready for the ‘Big One’
The coastal state, which scientists say experiences a major temblor every 150 years, is ‘10 months pregnant’ for a high-magnitude quake

Jones is the prime mover behind November’s Great Southern California ShakeOut, described as the nation’s biggest ever earthquake drill. If all goes to plan, millions of southern Californians will declaim the mantra of “Drop, cover and hold on” as they simulate their response to a 7.8-magnitude earthquake on the San Andreas fault, southeast of Los Angeles.

The earthquake model devised for the ShakeOut is, to put it mildly, alarming. Every 150 years, the southern San Andreas fault experiences an earthquake of the magnitude envisaged by the study. The last one was 151 years ago. As one seismologist noted last year, the fault “is 10 months
pregnant.”

“It’s absolutely inevitable,” Jones said. “The only question is whether it is in our lifetime.”

One recent study by the US Geological Survey put the likelihood of such an event happening in the next 30 years at 46 percent. The probability of a 6.7 magnitude quake was estimated at 99 percent.

According to Jones, the Big One in her model will cause 1,800 deaths and US$213 billion in economic losses. That’s the good news. The bad news is far more scary. The initial tremor will cause buildings to collapse, freeways to buckle, pipes to burst, craters to open in the ground, and fires to start.



Tokyo quake 'to leave 530,000 homeless'

Up to 220,000 households, or 530,000 people, would remain homeless for about six months if a major earthquake with an epicenter located beneath the Tokyo metropolitan area hit Tokyo and its vicinity, according to a report by a team of academics.

The team, comprising researchers of Tokyo University and Tokyo Institute of Technology, warns in a report that temporary and rental housing available after a massive quake would not be sufficient to accommodate those who have lost their homes.

Therefore, it is important to make homes more earthquake-resistant ahead of a major disaster, it said.


Yellowstone supervolcano is only lukewarm


How hot is the Yellowstone hotspot? At 80 kilometres beneath the Earth's surface it's about 1450 °C, say researchers – which, for a supervolcano, is only lukewarm.

That doesn't mean we won't get another eruption. The last explosion, some 642,000 years ago, created the Yellowstone caldera and blanketed half of the present day US in ash.

But Derek Schutt of Colorado State University believes the relatively tepid temperature means the supervolcano could be on its last legs.

Yellowstone National Park in the US is one of a few dozen volcanic hotspots around the world, along with the likes of Hawaii and Iceland.
