Earth moved 140cms (4 feet and 7.12 inches) after Chile earthquake: Scientists


Satellite images show earth displaced by 140cm after the 16 September quake in Chile
The Earth was displaced by 140cms after a massive 8.3 earthquake rocked Chile's north coast on September 16, according to satellite images taken before and after the temblor, which were analysed by scientists, using a technique — called Synthetic Radar Aperture Interferometry (InSAR) .

This technique combines before and after satellite images into colorful maps — called interferograms.

The rainbow-colored fringes, which can be similarly interpreted as the elevation contours on a map, help scientists approximate how far the ground moved on a fault following an earthquake. The European Space Union launched the spacecraft that took these images, called Sentinel-1, in the Spring of 2014. It orbits about 430 miles above Earth and uses radar to sense ground movements.


4.7-magnitude earthquake strikes northwest Nevada; third in 10 months

The U.S. Geological Survey reports that a 4.7-magnitude earthquake hit the northwest corner of Nevada on Saturday night — the third earthquake of this size to hit the region in the past 10 months.

The USGS says the earthquake, which had its epicenter about 38 miles southeast of Lakeview, Oregon, hit at 7:44 p.m.

There are no reports of damage in the region.

On Sept. 14, a 4.7-magniture earthquake hit the Shelton National Wildlife Refuge near the Oregon and California borders.

That earthquake was the second of 4.7 magnitude to hit the Sheldon wildlife refuge. The first one, recorded on Nov. 6, 2014, was the largest one to hit since the thousands of earthquakes started in July 2014.

Officially, 6.7 inches of snow blanketed the city of Fairbanks Friday, turning the city into a winter wonderland just days into fall. Not only was this the city's first measurable snow of the season, but this was the city's third heaviest calendar-day September snow on record, topped only by Sep. 13, 1992 (7.8 inches) and Sep. 29, 1972 (7 inches). This was the city's heaviest September snow event since a four-day, 17.3-inch snow blitz from Sep. 11-14, 1992.

Fairbanks only averages 1.9 inches of snow during the month of September. Two observers in College Hills north of downtown Fairbanks measured 9 inches of snow as of Friday afternoon, according to the National Weather Service.

The Alaska DOT reported about 10 inches of snow in the hills near Nenana west-southwest of Fairbanks along the Parks Highway, the primary link between Fairbanks, Denali National Park and Anchorage.

A moderate earthquake jolted residents in Cartago and San José provinces at 8:45 a.m. Saturday. No damage was reported.

The National University's Volcanological and Seismological Observatory of Costa Rica (OVSICORI) reported the temblor as a magnitude-4.6. The University of Costa Rica's National Seismological Network (RSN) registered a magnitude of 4.5.

Both agencies reported the epicenter in the province of Cartago, 17 kilometers east of Turrialba canton. The quake struck at a depth of 19 kilometers and was felt across most of the Central Valley.

People reported via OVSICORI's and RSN's social media accounts that the temblor as "very strong" in the Cartago communities of Agua Caliente, Turrialba, Tejar and Tres Ríos. Reports from San José came mostly from residents east of the capital in Curridabat, Zapote, San Pedro and Patarrá.

Scooter, before and after the attack
Two dogs suffered injuries consistent with a wolf attack last month in a part of Oregon with no recent confirmed wolf activity.

A veterinarian expects both dogs to make full recoveries, according to the Oregon Cattleman's Association.

And the Oregon Department of Fish and Wildlife said DNA analysis of samples from the injured dogs may help confirm the attacker was wolf.

On Tuesday, August 25, Buck and Chelsea Matthews found their dog Scooter on the porch of their home in rural Wallowa County with teeth marks on its neck.

"Scooter was laying by the front door when I headed out in the morning," Buck said in an Oregon Cattleman's Association press release on the incident. "I thought he was dead. He was laying on his side obviously injured and bleeding from his back and front legs."
