Russian scientist: Eruption of Koryak Volcano Might be Dangerous

Authorities of Kamchatka Territory and Petropavlovsk-Kamchatsky City must get ready for a big swell of eruption of the
Koryak Volcano
located at the 30 km distance from the city and its airport
, which is the major air gateway of Kamchatka.

Alexei Ozerov, the leading scientist of the Volcanology and Seismology Institute of Far Eastern Branch of the Russian Academy of Science has recently reported about this to RIA Novosti.

Flashback Yellowstone Volcano Rises at Unprecedented Rate

© R.L. Christiansen/USGSThe Yellowstone Caldera. The best estimate of the caldera rim is shown salmon. White arrows show interpreted magma migration paths. The red symbols mark volcanic centers that erupted after the caldera formed 640,000 years ago. The areas of known past or present thermal activity are colored yellow.
Yellowstone's ancient volcanic floor has been rising since mid-2004 because a blob of molten rock the size of Los Angeles infiltrated the system 6 miles beneath the surface, scientists say, but there is no risk of an eruption.

Yellowstone National Park is the site of North America's largest volcanic field, which is produced by a hotspot, or gigantic plume of hot, molten rock, that begins at least 400 miles (643 kilometers) beneath Earth's surface and rises to 30 miles (48 kilometers) underground, where it widens to about 300 miles across.

Occasionally, blobs of magma break away from the top of this plume and rise up to resupply the magma chamber beneath the park's "caldera," a 40-mile by 25-mile bowl-like depression and volcanic leftover whose walls you can see in the northwest part of the park.

These rising blobs of magma can sometimes push on the caldera floor, causing it to rise. Scientists monitoring the Yellowstone caldera think that's exactly what has caused the caldera floor to rise by almost 3 inches (7 centimeters) per year over the past three years - more than three times faster than it has more typically risen since observations began in 1923.

"Our best evidence is that the crustal magma chamber is filling with molten rock," said study leader Robert Smith, a seismologist at the University of Utah. "But we have no idea how long this process goes on before there either is an eruption or the inflow of molten rock stops and the caldera deflates again."

Scientists eye unusual swarm of Yellowstone quakes

Cheyenne - Yellowstone National Park was jostled by a host of small earthquakes for a third straight day Monday, and scientists watched closely to see whether the more than 250 tremors were a sign of something bigger to come.

Swarms of small earthquakes happen frequently in Yellowstone, but it's very unusual for so many earthquakes to happen over several days, said Robert Smith, a professor of geophysics at the University of Utah.

"They're certainly not normal," Smith said. "We haven't had earthquakes in this energy or extent in many years."

Smith directs the Yellowstone Seismic Network, which operates seismic stations around the park. He said the quakes have ranged in strength from barely detectable to one of magnitude 3.8 that happened Saturday. A magnitude 4 quake is capable of producing moderate damage.


Yellowstone Earthquakes Under Supervolcano Caldera

The headline "Scientists track unusual earthquake swarm beneath Yellowstone" only means one thing to fans of the Discovery channel like myself: supervolcano. Here is what the earthquake center at the University of Utah had to say yesterday afternoon:
The University of Utah Seismograph Stations reports that a notable swarm of earthquakes has been underway since December 26 beneath Yellowstone Lake in Yellowstone National Park, three to six miles south-southeast of Fishing Bridge, Wyoming. This energetic sequence of events was most intense on December 27, when the largest number of events of magnitude 3 and larger occurred.

Oregon town an earthquake hot spot

The Dalles -- Scientists say they have yet to definitively determine what is causing the town of Maupin, Ore., to endure an earthquake every other day.

Oregon State University research associate Jochen Braunmiller said during the last two years, more than 360 earthquakes have occurred in the general vicinity of Maupin for elusive reasons, The (Portland) Oregonian said.

The College of Oceanic and Atmospheric Sciences researcher said while one theory focuses on water level shifts miles underground, scientists are at a loss to offer predictions regarding the quakes.

"It just kind of keeps going," Braunmiller said. "Overall, we know stress is being released so we think it will stop at some point. But we cannot say when that will happen or whether we have seen the largest one yet."

Yellowstone rattled by "swarm" of quakes

A swarm of earthquakes continued to rattle Yellowstone National Park on Monday. Over the past two days, more than 37 temblors have shaken the earth below Yellowstone Lake, causing scientists to speculate on the cause and field questions on whether the quakes were a prelude to an eruption of the park's super volcano.

"It's an energetic earthquake swarm," said Mike Stickney, director of the earthquake studies office for the Montana Bureau of Mines and Geology. "I'm hearing reports that people in the park have been feeling some of them."


Princeton Physicist Calls Global Warming Science "Mistaken"

Scientist fired by Al Gore was told, "science will not intrude on public policy".

Noted energy expert and Princeton physicist Dr. Will Happer has sharply criticized global warming alarmism. Happer, author of over 200 scientific papers and a past director of energy research at the Department of Energy, called fears over global warming "mistaken".

"I have spent a long research career studying physics that is closely related to the greenhouse effect", said Happer. "Fears about man-made global warming are unwarranted and are not based on good science."

Dr. Happer views climate change as a predominately natural process. "The earth's climate is changing now, as it always has. There is no evidence that the changes differ in any qualitative way from those of the past."


Flashback "La Nina" effect may be behind shark attacks

Zihuatanejo, Mexico - Cooler than normal sea-surface temperatures due to the La Nina phenomenon may be partly responsible for a spate of fatal shark attacks off Mexico's Pacific coast, a U.S. shark expert said on Friday.

At least two people -- a surfer and a U.S. tourist -- have been killed by sharks in the last few weeks around the coastal town of Zihuatanejo in the state of Guerrero.

La Nina, which usually results in cooler than normal water in the Pacific, has moved the boundary between cold and warm water closer to the shore, and along with it, fish and their shark predators, George Burgess, director of the Florida Program for Shark Research told Reuters.


Flashback La Nina Causing Global Mayhem

Deadly heat bakes the Midwest and East Coast, floods leave millions homeless in Asia, and a tinder-dry Los Angeles city waits for wildfires.

All of this global weather mayhem and more comes courtesy of La Nina.

A cooling of the ocean surface off the western coast of South America, occurring periodically every 4 to 12 years and affecting Pacific and other weather patterns, which forecasters said Thursday is certain to rebound this winter after showing hopeful signs of weakening during the spring.

For Southern California and the world, that means another year of climate chaos, including a second dry and dangerous fire season for Los Angeles and a host of hurricanes to batter the Atlantic coast.
