8.5 magnitude earthquake hits Oaxaca, Mexico, cutting power and sparking mysterious lights

The death toll from an 8.2-magnitude earthquake that hit Mexico has reached at least 32, according to tallies from local authorities.

Twenty-three of the confirmed fatalities were in the state of Oaxaca, according to its governor. Seventeen of those deaths occurred in the town of Juchitan.

Seven people were killed in the state of Chiapas, where a state of emergency has been declared, according to a spokesman for emergency services cited by Reuters.

Two children were killed in neighboring Tabasco state, according to its governor. One was crushed by a collapsing wall, while the other - an infant on a respirator - died after the quake triggered a power outage in the hospital.

The epicenter of the quake was at a depth of 33 km (21 miles), 123 km (76 miles) southwest of the town of Pijijiapan, not far from the Guatemalan border.

Comment: Hospital ventilators failed as the earthquake struck:
The quake caused widespread power outages and as a 0.7-metre wave hit the country, the Pacific Tsunami Warning Centre confirmed more hazardous tsunamis were possible within three hours.

The death toll includes two children in Tabasco state.

Tabasco Govenor Arturo Nunez said one of the children died when a wall collapsed, and the other was a baby who died in a children's hospital that lost electricity, cutting off the supply to the infant's ventilator.
Earthquake lights, a commonly reported phenomenon, were seen:
One person took a video of the earthquake light phenomenon which often happens after an earthquake strikes.


Little is known about why they occur and some believe it may be as a result of power supplies being hit while others claim that they have been reported for thousands of years.

Seismologist Stephen Hicks said: 'Earthquake lights have never been proven. Simpler explanation is small explosions in electric generators and power systems.

The lights are similar to auroras and can sometimes continue for several minutes after or before the quake.

For example in 1975, the mystery lights appeared during and immediately after the main shock in the Kalapana earthquake in Hawaii.

They come in many colours and forms and people have reported seeing them for hundreds of years but only recently have scientists come a little closer to establishing why they appear.
More on the light phenonmenon:
Another explanation claims that the tectonic movement of rocks including quartz, generates a piezoelectric field which produces flashes of light.

A 2014 study said the stress of the tectonic plates can break apart pairs of negatively-charged oxygen atoms, pushing them towards the Earth's surface and forming a light-emitting plasma when it combines with air.

6.1 magnitude earthquake hits off the Bonin Islands, Japan

A 6.1-magnitude earthquake hit off Japan's Bonin Islands on Thursday but there was no tsunami risk, seismologists said.

The quake hit at a depth of 450 kilometres (280 miles) at 02:27 am (17.27 GMT) 770 kilometres south of Shimoda, according to the United States Geological Survey.

Japan Meteorological Agency said the quake poses no tsunami risk.

A 9.0-magnitude earthquake in March 2011 triggered a massive and deadly tsunami, which smashed into a power station and sparked the world's worst atomic accident since Chernobyl in 1986.

Tokyo Electric is working to clean up and dismantle the reactors in a process that is expected to take at least four decades.

A number of earthquakes were detected at Bárðarbunga in Vatnajökull tonight, according to the Icelandic Met Office. The largest quake was 4.1 in magnitude, with another one following at 4.0.

The quakes were a total of 21, with three of them over 3.0 in magnitude. There are currently no signs of increased volcanic activity in the area, although it has seen a large number of quakes over the past years.

Bárðarbunga is located north-west of Vatnajökull, Iceland's largest glacier. It is considered a highly active volcanic area, having last erupted between the years 2014-2015.

Over 100 aftershocks rattle Idaho as earthquake swarm continues

More than 100 aftershocks have rattled southeastern Idaho since a 5.3 magnitude quake hit near the town of Soda Springs late last week, and experts say they could continue for another week or so.

The 5.3 quake hit was the second in the series, and it hit about 6 p.m. Saturday. There were no reports of injuries or damage, though officials say 17,000 people reported feeling the 5.3 quake from as far away as Salt Lake City, Utah.

Soda Springs resident JoAnna Ashley was in nearby Georgetown visiting her parents when the biggest earthquake hit. She grabbed onto the shaking refrigerator and watched as a bottle of tiki torch fuel perched on top wobbled toward the edge. Her kids, ages 5 and 8, grabbed onto Ashley during the shaking.

"They didn't scream, but were all, 'Momma, what's happening?' in that worried voice," Ashley said.

The swarm won't stop: 62 earthquakes strike southeast Idaho in one day

The strongest earthquake to hit the region in years as well as 61 smaller quakes occurred Saturday night to Sunday night in Southeast Idaho, startling tens of thousands of residents.

Authorities said it does not appear that the quakes have caused any injuries to people or damage to structures (ADVICE ON WHAT TO DO IF AN EARTHQUAKE HITS YOUR TOWN IS AT THE END OF THIS ARTICLE).

The quakes were felt in Caribou County, where all 62 occurred, as well as in cities in northern Utah and throughout Southeast Idaho. It's unknown when the earthquake swarm will end. Earthquake swarms have been known to continue for weeks or even months.

In recent decades Southeast Idaho has seen infrequent instances in which one to three weak earthquakes occur near the Western Wyoming border. Local authorities say they cannot ever remember any earthquake swarm in Southeast Idaho that comes even close to the current series of temblors shaking the region.

Idaho earthquake
An 5.3 earthquake followed by half a dozen aftershocks have struck Idaho near the state border with Wyoming, some 28 km east of Soda Springs which has a population of roughly 3,000 people, the USGS announced.

The earthquake which struck just before 6pm was registered at a preliminary 10 kilometers (6.2 mi ) depth.

Several aftershocks measuring from 3.1 to 4.1 magnitude have been recorded following the initial quake.

It is not yet known if the earthquake caused any damage or injuries, but Fox 13 local news reports that it received several calls and messages from people who felt tremors as far as the state of Utah.

An ongoing earthquake swarm at Yellowstone volcano is now one of the biggest ever recorded, with over 2,300 tremors since it began in June.

As of August 30, 2,357 earthquakes had been recorded. The most powerful in recent weeks was magnitude 3.3; it took place on August 21.

The most powerful in the current swarm was a magnitude 4.4, which was recorded on June 15. Most of the earthquakes were in the magnitude 0 or 1 range, with a further 181 recorded at magnitude 2 and 11 at magnitude 3. Another 53 were less than 0, meaning they were very small events that could be detected only with sensitive earthquake-monitoring instruments.

Jamie Farrell, a research professor at the University of Utah, which is involved in monitoring seismic activity at Yellowstone, told Newsweek that the swarm was "nothing out of the ordinary" and that it had "slowed down significantly but does occasionally have little bursts of activity that lasts for a few hours."
