The U.S. Geological Survey says a magnitude-6.5 earthquake has struck off the coast of Chile. The quake was recorded at 5:49 a.m. local time (EDT; 0949 GMT) Monday, at a shallow depth of 10 kilometres, some 600 kilometres from the city of Puerto Quellon. No tsunami warning was issued. Chile's naval seismology office says it was not felt on land. U.S. seismologists originally estimated the magnitude at 6.8. Chile is one of the world's most earthquake-prone countries. A magnitude-8.8 quake and the tsunami it unleashed in 2010 killed 551 people and destroyed 220,000 homes. It was so strong it changed time, shortening the Earth's day slightly by changing the planet's rotation. The strongest earthquake ever recorded also happened in Chile, a magnitude-9.5 in 1960. - CTV News

USGS Technical data

Tornadoes touched down in three states on Sunday, ripping roofs off homes and turning trees to matchsticks, as severe weather swept the region. A large "violent and extremely dangerous" tornado was spotted on the southwest side of Wichita, Kansas, the National Weather Service said. A second confirmed tornado was seen near Edmond, Oklahoma, said the weather service. Another tornado was spotted in nearby Luther, Oklahoma, but it was not immediately clear whether that was the same twister. A third tornado touched down near Wellston, Oklahoma, taking out power lines and damaging several homes, according to video from CNN affiliate KFOR. The affiliate's helicopter pilot estimated the funnel cloud to be about a half-mile wide. "It's tearing up everything," the pilot said. "Just ripping everything up in its sight."


Aerial video from KFOR and CNN affiliate KOCO showed severe damage near Wellston and near Carney, Oklahoma. Roofs were ripped from homes, branches stripped from trees and roads were filled with debris. Tornadoes were also reported east of Dale, west of Paden, and near Prague in Oklahoma. Part of Interstate 40 in Shawnee, Oklahoma, was shut down in both directions Sunday night after a tornado touched down, overturning multiple tractor-trailers. Still more tornadoes were spotted in Iowa, near Earlham, Huxley and east of Dallas Center, according to the weather service. It did not mince words, telling people to take cover there, as elsewhere. "You could be killed if not underground or in a tornado shelter.

A massive earthquake swarm has occurred in the region of Petropavlovsk-Kamchatskiy, Russia. More than 20 earthquakes have struck the region in the last 22 hours- the strongest of which was a 5.9 magnitude earthquake, which rattled the seafloor at a depth of 16.5 km deep. The latest seismic flare-up along this region reflects growing agitation on one of the planet's largest tectonic plates- the Pacific plate. Increasing seismic volatility along this region of Kamchatka could have serious ramifications for every tectonic plate that comes into contact with the Pacific plate- from the South Pacific to South America. A similar, more intense earthquake swarm occurred along the periphery of the Pacific Plate near the Santa Cruz Islands in February of this year. Is the Pacific plate on the verge of a large-scale change?

Migratory murder on Egypt's coast

May 2013. Disturbing evidence has emerged from the Mediterranean coast of Egypt: Bavarian Broadcasting have documented a total of 700 kilometres of nets set to catch birds. The birds are then offered as a delicacy in markets and restaurants across Egypt.

The nets are very difficult to avoid for many migratory birds as they form a barrier across their flight path either across the Mediterranean or the Sahara when they are looking for a place to rest. The exact number of birds caught in this way can only be estimated, but experts believe that tens of millions are killed each year.

That songbirds are on the menu (and targeted by many hunters) in many countries of southern Europe and North Africa is nothing new. The existence of fishing nets on the coast of Egypt has long been known, but what is new is the scale of netting, which now extends from Libya across almost the entire coastline of the Egypt to the Sinai - interrupted only in a few places by military installations or major cities.

Red tide' and a loss of sea grass account for some manatee deaths, but researchers believe undiscovered factors are also at play.

A record number of endangered manatees are dying in Florida's algae-choked waterways. So far this year, 582 manatees have died, more than any year on record, according to preliminary numbers from the Florida Fish and Wildlife Conservation Commission (FWC).

Pat Rose is an aquatic biologist and the executive director of the Save the Manatee Club, an organization devoted to preserving the animal. In his interview with TakePart, Rose reports the estimated minimum population of these gentle beasts is only 3,100 adults. That means their population has decreased by more than 10 percent in just four months.

A total of 247 of these have died in the southwest of the state due to an explosion of a red-hued algae called Karenia brevis, also known as a red tide.

This pesky microorganism produces neurotoxins that can kill manatees by causing them to seize to the point where they can't make it to the surface - or even lift their head out of the water - to breathe.

The large marine mammals are also dying in the eastern part of the state, in Brevard County near Orlando. Rose says a gradual die-out of sea grass, upon which the manatees feed, has combined with blooms of brown algae and likely other unknown factors to kill nearly 150 more manatees. Since 2010, about 30,000 acres of sea grass have been wiped out.

Luckily, it appears that both events are winding down, and the rate of manatee deaths appears to be slowing. But that's cold comfort for Rose, since the number of threats to manatees appears to be growing, and little is being done to address the problem.

Traditionally, boat collisions have been the biggest killer of manatees; they're vulnerable since they're large, slow-moving and often hang out on the surface. Until this year, at least 41 percent of all manatee deaths resulted from these collisions, and likely more, because not all of these deaths are reported or detected.

When it comes to mysteries, there's no better place for hiding them than the bottom of the ocean. In fact, according to the National Oceanic and Atmospheric Administration (NOAA), as much as 95% of the world's oceans remain unexplored.

And yet some people don't believe in sea monsters.

Well, thanks to the advent of the internet, we can do some of that exploring from the comfort of our computer chairs, and you never know what sorts of strange stuff will turn up. Our pal Samuel Burgan (AKA IceBurg) was doing just that, and found a bunch of bizarre markings on the ocean floor, so he sent a few snapshots our way.

Chilean Navy discovers more than 600 dead animals in Punta de Choros, a small fishing town north of La Serena.

The bodies of sea lions, cormorants and penguins littered a seven mile stretch of beach in Punta de Choros, northern Chile on Sunday. The crime scene is in close proximity to the Humboldt Penguin Nature Reserve.

Two days prior the Movement in Defense of the Environment (MODEMA) reported a band of ten fishing boats off the coastline of Punta de Choros. MODEMA and other environmental groups accused the boats of blast fishing - using explosives to catch mass quantities of fish.

Sernapesca, Chile's National Fishing Service, investigated the scene and determined that all the animals were killed by the same incident. Autopsies report animals with fractured skulls, missing rib cages and multiple abrasions.

Local authorities promptly called in the Investigative Police's (PDI) Environmental Crime Brigade for further investigation. Microbiological and chemical analysis tests are currently being run to determine if blast fishing is the cause of death.

In Chile, blast fishing is illegal. Companies caught fishing in this manner face prison time and fines. The monetary amount depends on the damage to the ecosystem. However, causing the death of penguins during commercial activities is a jailable offense. Officials from Sernapesca told The Santiago Times that the combined offenses amount to a "serious crime."

Fairbanks - Birds of all kinds are arriving in dizzying numbers and many long-time birders say they have never seen such a concentrated wave of migrating birds in the Tanana Valley.

Bud Johnson in Tok estimates there were 100,000 sparrows descending on that area Tuesday. He reported seeing continuous flocks along the sides of the highway, and came home to hundreds of songbirds in his yard. White-crowned, golden-crowned, fox and tree sparrows mixed with juncos, rusty blackbirds and Lapland longspurs. Other viewers saw Lincoln's and Savannah sparrows and gray-crowned rosy-finches.

"I have never seen anything like this ever," Johnson said. "The ground is just in constant movement and the singing (mostly from the white-crowned sparrows) is insane."

Among bird-watchers, there is a phenomenon called "fallout," which is when a large number of migrating birds make landfall because they run into storm systems. Usually this happens along the coast, where exhausted birds touch down on the first solid ground they find. It's possible a combination of the late spring breakup and a current weather front has caused this unusual spring gathering.

"This is turning out to be the most spectacular spring migration I think the Tanana Valley has seen in recent memory," Fairbanks birder Nancy DeWitt wrote in an email. "First, there were the unprecedented numbers of swans and white-fronted geese in the Delta barley fields (many of which are still there) accompanied by the biggest flocks of Canada geese and pintails I've ever seen, now followed by what Steve Dubois says is the largest concentration of sandhill cranes he's seen in his 28 years there.

"Add in the numerous bluebird sightings (I've lost count), cloud after cloud of Lapland longspurs moving through the valley, thick groups of varied thrush at Fort Greely on Saturday night, and now the sparrow fall-out in Tok Bud describes, and I am just beside myself with glee," she said. "I assume most of this is weather related, but what happened and where along the migration route that balled up all these birds? I suppose the fact that a lot of the valley is snow-covered and many ponds and lakes are still frozen is also concentrating birds, but would sure love to know if anyone tracked migration radar data over Canada in the past month.

Christmas music played Friday in the lobby of the McKinley Chalet Resort, just outside Denali National Park and Preserve.

It was fitting, considering the weather outside.

A heavy spring snowstorm dumped enough snow in the area to cancel some local events, keep people from driving and surprise a few tourists.

A winter storm watch remained in effect until this morning.

"The guests are actually enjoying the experience," said Craig Pester, district manager of Aramark's Denali resorts. "We had to change a couple tours around so they didn't get the full experience, but all the guests are very happy. They're kind of making it part of their adventure."

Indeed, the Elliotts who are visiting from South Carolina thought the snow was pretty exciting, as they huddled behind an umbrella. What an Alaska experience, they said.

A visitor from Germany came north for better weather and ended up camping in the snow at Riley Creek Campground. He took it all in stride.

Cold air across so much of Alaska, so late in the year, has delayed summer for the winter weary and left thousands of international travelers in holding patterns. An unexpected bonanza of migrating birds are reportedly hunkered down northwest of Denali National Park and Preserve. In the Delta-Tok region, thousands more cranes, swans, geese, and swallows than usual are waiting out conditions unusual even for Alaska.

Birds often "ball-up" in foul weather, congregating along coastlines and then fly over vast Interior Alaska in waves. Not this year. One local birder told the Fairbanks Daily News-Miner he'd never seen so many stopped over, all at once, in more than 20 years.

Arctic air pushing southward and smaller low-pressure systems have kept cold weather lingering. Up to 6 inches of snow was forecast over the weekend in Anchorage, with accumulation likely in Fairbanks as well, the National Weather Service predicted, though ground temperatures would melt most of it.

Normally, late May sees warmer air from the Gulf of Alaska pulled north across the state, but for now, at least, much of Alaska remains near freezing or colder.

"It is a real fluke. We just haven't gotten into our summer pattern yet," meteorologist Dan Peterson said. Next week, forecasts called for highs in the 50s and 60s from Anchorage, in Southcentral Alaska, north to Fairbanks.
