Iceland: Small earthquake swarm in Krísuvík volcano

Krísuvík
© Unknown
The Krísuvík volcanic system (also spelled Krysuvik) consists of a group of NE-SW-trending basaltic crater rows and small shield volcanoes cutting the central Reykjanes Peninsula west of Kleifarvatn lake. Several eruptions have taken place since the settlement of Iceland, including the eruption of a large lava flow from the Ogmundargigar crater row around the 12th century. The latest eruption at Krísuvík took place during the 14th century.
Currently there is a small earthquake swarm in Krísuvík volcano. This earthquake swarm is small and is only about 20 or so earthquakes at current time. It is impossible to know if this earthquake swarm is going to continue or grow at present time. But it is not uncommon in this area for a small earthquake swam to be a warm up for a larger one. But as always there is just a wait and see what happens in the area.

Big Sunspots

Sunspot complex 1161-1162 quieted down over the weekend, producing few intense flares. Could it be the quiet before the storm? The tempestuous appearance of the region suggests more action could be in the offing. Rogerio Marcon sends this picture from his backyard observatory in Campinas SP Brasil:

Marcon recorded the image using an H-alpha filter tuned to the red glow of solar hydrogen. It reveals several dark magnetic cores, each larger than Earth itself, interconnected by turbulent arcs of magnetized plasma. Similar filters are now available in the Space Weather Store for readers who would like to see these 'spots with their own (safely filtered) eyes.

NOAA forecasters estimate a 60% chance of M-class solar flares during the next 24 hours. Stay tuned for action.

Baby dolphin deaths spike on Gulf Coast

Gulfport -- Baby dolphins, some barely three feet in length, are washing up along the Mississippi and Alabama coastlines at 10 times the normal rate of stillborn and infant deaths, researchers are finding.

The Sun Herald has learned that 17 young dolphins, either aborted before they reached maturity or dead soon after birth, have been collected along the shorelines.

The Institute of Marine Mammal Studies is doing necropsies, animal autopsies, on two of the babies now.

High Winds Topple U.S. National Christmas Tree

America's National Christmas Tree came tumbling down Saturday in a windstorm that battered the U.S. capital.

The 47-year-old, 42-foot-high (13-metre) Colorado blue spruce, which the president lit each year to mark the Christmas season, snapped near its base on the Ellipse near the White House.

"We're glad that there are no injuries," said Bill Line, a spokesman for the National Park Service.

Compass

Pilots, boaters adjust to shift in magnetic north

Magnetic north, the point at the top of the Earth that determines compass headings, is shifting its position at a rate of about 40 miles per year. In geologic terms, it's racing from the Arctic Ocean near Canada toward Russia.

As a result, everyone who uses a compass, even as a backup to modern GPS navigation systems, needs to be aware of the shift, make adjustments or obtain updated charts to ensure they get where they intend to go, authorities say. That includes pilots, boaters and even hikers.

"You could end up a few miles off or a couple hundred miles off, depending how far you're going," said Matthew Brock, a technician with Lauderdale Speedometer and Compass, a Fort Lauderdale company that repairs compasses.

New Zealand: Oyster Virus Shuts Hatchery

A herpes virus that has devastated North Island oyster farms and so far cost about $12 million in potential sales has shut the pioneering Nelson hatchery that supplies 20 per cent of New Zealand's stock.

No explanation has yet been found for how the virus, which has killed about half of Northland's farmed pacific oysters due for harvest next year, got into the Cawthron Institute's hatchery at The Glen.

But there was nothing to suggest that the hatchery itself, opened with great fanfare in mid-2009, was the source of the outbreak, Cawthron business development manager Mike Mandeno said yesterday.

"It's a temporary setback for us in terms of producing more stock. We'll be trying again at the end of the month."

Juvenile-farmed Northland oysters began dying towards the end of last year and the cause was identified by MAF scientists as a form of herpes which poses no risk to humans but which has been blamed for killing large numbers of oysters in France over the past three years. It is also found in many other countries, including Australia.

Mt. Bulusan Erupts: Major Volcano Eruption In Philippines

Philippines volcano Mount Bulusan erupted on Monday morning at 9:15 a.m. local time, per the ABS-CBN News Channel.

Ash and steam from the explosion reached as high as 2 kilometers, according to the report.

The Philippine Daily Inquirer posted this photo of the Mount Bulusan eruption to Posterous.

Journalist Harold Geronimo of Manila, Philippines, was the first to report the eruption on Twitter, sending this tweet from his Blackberry minutes after the eruption.

Mount Bulusan had increased volcanic activity in November 2010, spewing ash and steam over several days (the photo above is from Nov. 2010). Families were evacuated at the time.
