Landslide strikes cliff in Des Moines, Washington - homes at risk

Image
A landslide Friday afternoon endangered three homes overlooking Puget Sound in Des Moines, damaging at least one of them. The homes were evacuated and no injuries were reported after the slide north of Saltwater State Park, South King Fire Lt. Jeff Bellinghausen said. The slide happened just before 4 p.m. along the bluff at 25100 8th Place S., according to South King Fire Department officials. A homeowner noticed the ground moving around 8:30 a.m. on Friday, and occupants were able to get valuables out of their homes before leaving. It wasn't until mid-afternoon that the man's backyard virtually disappeared. "Well it's awful of course, I hate to see it, I feel bad for the neighbors," Dorn Porter said. Most neighbors who live close by say they had no idea anything had happened until they saw emergency responders, and Air 4 hovering above their houses.

At 200-feet across, and 2000-feet down, it will take several days to figure out what caused the slide, and for the land to stop moving. South King County deputies say they'll be monitoring the area throughout the night, and more evacuations are possible. "They just seem to start, and bang, it's gone and it's over and you do what can to shore yourself up," Porter said. The area was already considered a "sensitive critical area," officials said. There have been smaller slides in the past, but nothing as extreme as Friday's slide. "We knew this wasn't something usual, wasn't a normal event," Elisa Dawn Harrison said. Harrison was at the park below when she caught part of the slide on camera. "I just feel bad for anyone who has to go through this." No injuries were reported, but the community worries what may come next. The back deck slid down a hill, and trees and dirt continued to fall down to the beach below. Crews were at the scene to assess the risk of further damage, Bellinghausen said. - Seattle Times

Magnitude 5.5 earthquake rattles Crete

A 5.5 magnitude earthquake has hit northeast of the island of Crete, Greece, according to a preliminary reading by the US Geological Survey.

The tremor struck at 1:34 am local time on Saturday, with the epicenter located 83 miles (133 km) ENE of Iraklion, Crete, Greece.

There are no reported casualties but the quake was strong enough to worry locals in Crete and the neighboring Greek islands.

Earthquakes have historically caused widespread damage across central and southern Greece, Cyprus, Sicily and other neighboring regions. Last year a series of strong earthquakes on the island of Kefalonia damaged hundreds of homes and injured more than a dozen people.

The U.S. Geological Survey says a moderate earthquake struck west of Vancouver Island.

The magnitude 4.9 temblor hit Wednesday about 12:22 p.m. about 90 miles southwest of Port Hardy, British Columbia.

Port Hardy Mayor Hank Bood says the quake was not felt in his community on northern Vancouver Island.

Natural Resources Canada says there were no reports of damage, and none was expected. No tsunami warning was issued.

Magnitude-6.4 earthquake rocks Northern Chile

A major earthquake struck early Monday morning in northern Chile.

The National Seismological Service at the University of Chile initially listed the temblor at a magnitude-6.3. The U.S. Geological Survey listed it as a magnitude-6.4.

The temblor's epicenter was located 48 kilometers (30 miles) east-southeast of Putre, Chile, at a depth of 128 km (180 miles), the USGS reported. It was near the borders with Peru and Bolivia, and occurred at 12:51 a.m. local time.

There were no immediate reports of injuries or damage from the region.

No tsunami was expected as a result of the earthquake, according to the Chilean Navy Hydrographic and Oceanographic Service.

The earthquake was felt in Tacna, Peru, but it didn't affect the electrical system, according to the USGS and Twitter users.

Mexico City shaken by earthquake that struck more than 100 miles away

Mexico City locals flooded the streets after the quake
An earthquake that caused buildings to sway and forced people to flee onto the streets in the Mexican capital happened more than 100 miles away.

The quake hit at 4.30pm local time in the state of Puebla near Tulcingo del Valle - around 100 miles away from Mexico City.

But residents of the faraway capital were forced to flee shaking buildings.

The city is vulnerable to distant earthquakes because much of it sits atop the muddy sediments of drained lake beds that iggle like jelly when quake waves hit.

Mexico City Mayor Miguel Angel Mancera said many evacuations were reported in the capital but officials received no reports of damage or injuries.

The quake had a depth of 31 miles.

A magnitude-8.1 quake in 1985 that killed at least 6,000 people and destroyed many buildings in Mexico City was centered 250 miles away on the Pacific Coast.

Magnitude 6.3 earthquake strikes Papua New Guinea

A magnitude 6.3 earthquake struck off the Papua New Guinea island of New Britain on Monday, the U.S. Geological Survey (USGS) said.

The quake struck 6 miles (9 km), northwest of the town of Rabaul, on the northeast tip of New Britain island, it said. There were no immediate reports of any damage or casualties.

The U.S. Geological Survey has reported an earthquake that shook part of Swain County late Friday night.

The U.S.G.S. tracked the earthquake to Cherokee and said it happened at 11:51 p.m.

According to the U.S.G.S. website, this was a 2.8 magnitude earthquake.

More big earthquakes coming to California, forecast says

A new view of California's earthquake risk slightly raises the likelihood of big earthquakes in the Golden State, but lowers the chance that people in some regions will feel shaking from smaller, magnitude-6.7 quakes.

The new report does not predict when or where earthquakes will strike, nor how big the next quake will be; instead, it provides a better sense of how often earthquakes will occur and how likely faults are to break in the next three decades. This information helps set earthquake insurance rates and building codes in California.

Under the new forecast, the likelihood of a magnitude-8 earthquake in the next 30 years has increased from about 4.7 percent to 7 percent. A magnitude-8 quake would be twice as strong as the devastating 1906 San Francisco earthquake, a magnitude 7.8.

Meanwhile, the analysis said that Californians should expect a magnitude-6.7 quake to occur every 6.3 years somewhere in the state, which is less than the estimate of every 4.8 years from the previous forecast, released in 2007.

According to the new model, magnitude-8 earthquakes are still exceedingly rare in California. An earthquake of that size would require an extraordinarily long break along the San Andreas Fault, something that may happen only every 500 years.

"The model is probably good news for a homeowner, because they are more threatened by a small, local earthquake than a big, rare, distant earthquake," said Ned Field, lead author of the report and a U.S. Geological Survey research scientist in Golden, Colorado.

But earthquake insurance rates and building codes may change to reflect the uptick in great earthquakes, Field said. A magnitude-8 earthquake triggers long and fast shaking that is highly damaging to buildings and structures such as bridges.
