4.0 earthquake hits along New Madrid fault in Missouri; felt across the Mid-South

Image
Shortly before 11pm local time Wednesday night, an earthquake occurred along the New Madrid Fault Zone in far southeastern Missouri. The epicenter of the quake was near Steele, Missouri. Nearby cities include Blytheville, Arkansas and Hayti-Caruthersville, Missouri. The USGS reports it as a magnitude 4.0, occurring about 11 miles below the surface of the Earth.

KFVS-TV in nearby Cape Girardeau, Missouri reports it being felt as far away as Carbondale, Illinois. People on the station's Facebook page report feeling the shaking as much as 100 miles from the center. No damage or injuries have been reported with this quake. Typically, earthquakes in this part of the world with a magnitude of 4.0 don't do damage. However, earthquakes just a little stronger have been known to do minor damage within 25 miles of the epicenter.

Magnitude 6.0 earthquake strikes off coast of Fiji

A strong earthquake struck off the coast of Fiji Wednesday evening but poses no tsunami threat to Hawaii.

The preliminary magnitude 6.0 temblor struck 162 miles southeast of Lambasa, Fiji at 6:10 Hawaii time at a depth of 332 miles, according to the U.S. Geological Survey.

The quake did not generate a tsunami alert from the Pacific Tsunami Warning Center and no injuries were immediately reported.

Geologists try to map potential seismic hazard risks of New Madrid region of US

Image
April 2015 - NEW MADRID - The most recent update of the U.S. Geologic Survey earthquake hazard maps shows a big bull's-eye over the Bootheel. But the agency says there's no reason to panic. "We don't know that an earthquake is imminent — we can't predict earthquakes. But we do expect the past behavior in the New Madrid region to be a representation of how things might happen," said Robert Williams, Central and Eastern U.S. regional coordinator for the USGS in Golden, Colorado. "This is a ground motion hazard map, not a map showing the expectation of where earthquakes will actually hit," Williams said. The map shows there's a 2 percent chance over the next 50 years the area will exceed 80 percent of the acceleration of gravity. The USGS builds its earthquake hazard maps for engineers based on quakes that have occurred, Williams said. "But it's estimating the chance of exceeding ground motions in the next 50 years." Williams said the 50-year period is a common engineering design time interval for the life of a building. "Obviously you have to have an earthquake to get the ground motions, but doesn't try to say exactly where the earthquakes are going to occur and when they'll happen, just an estimate of future ground motions."

Huge sinkhole creates safety concerns in Riverdale, New York

A gaping sinkhole has opened up in Riverdale, creating safety issues for people in the neighborhood.
A gaping sinkhole has opened up in Riverdale, creating safety issues for people in the neighborhood.

Crews began repairs at Oxford Avenue and West 236th Street Monday. They say the massive hole started as a water main break late last week.

The Department of Environmental Protection told News 12 that the hole was repaired yesterday afternoon. However, the spot was still cordoned off on Tuesday creating a tricky four-way intersection for drivers.

Assemblyman Jeff Dinowitz's office looked more into the cause of the hole, and says the DEP inspectors determined that there were leaks to the 12-inch cast iron water main running underneath the street.

Sinkhole opens up and swallows man in Pennsylvania, but who pays to fix it?

A man was trapped in a sinkhole Friday night under the Mansfield Bridge, between Grassport and McKeesport.
A sinkhole has been covered alongside the W.D. Mansfield Memorial Bridge underpass carrying West Fifth Avenue traffic from McKeesport onto Monongahela Avenue in Glassport.

But it's uncertain who's responsible for its maintenance, three days after a man was injured falling into the sinkhole as it opened up under him.

"That is not the department's roadway," PennDOT District 11 spokesman Steve Cowan said. "My documents do not show who is the owner of the road, but I would think it would either be the municipality or the county."

Unidentified 'booms' have been waking up Berkeley for a month and nobody knows why

Strange, loud noises have been scaring pets, waking up children and triggering car alarms for more than a month in Berkeley, California, but local residents and police are still at a loss when it comes to identifying what's now called the "Berkeley Boom."

The first "booms" were reported to authorities on February 26, according to Berkeleyside. The noises haven't been heard every night, but streams of tweets have gradually documented their recurring nature, with people in neighboring Oakland and Emeryville also saying they've heard the sounds.

"I'd say it was around one in the morning, scared the hell out of me. I jumped out of bed," local resident Rachael Marzoline said to local KPIX 5, referring to the sound she heard on the evening of March 29.

Chile's Villarrica volcano explodes to life again

After a short period of rest, the Villarrica volcano in southern Chile recently exploded to life again, sending a plume of boiling ash high into the atmosphere.

The eruption triggered an increase in the alert level near the volcano to orange, the second highest rating.

The 2860-metre-high snow-capped stratovolcano, located 750 kilometres south of the capital Santiago, is one of the most active in Chile.

The latest series of eruptions began on 7 February with several minor explosions and ash plumes triggering a yellow alert.

A further pre-dawn eruption on 3 March sparked the evacuation of thousands of people from within a 10-kilometre radius of the volcano.

That eruption covered the mountain's eastern flank with a huge volume of volcanic material.

Villarrica is one of Chile's most active volcanoes with at least 66 recorded eruptions since the arrival of Europeans.

This image of Villarrica's latest eruption was taken from an altitude of about 700 kilometres by the Advanced Land Imager onboard NASA's EO-1 satellite on 18 March, 2015.

An early morning earthquake that struck two kilometers north of Vara Blanca, Heredia, produced more than 70 aftershocks, according to the National Seismological and Volcanological Observatory (OVSICORI).

The initial quake, measuring 4.6-magnitude on the Richter scale, struck at 3:09 a.m. Aftershocks continued until 5:17 a.m., according to OVSICORI.

Significant shaking was reported in various sectors of Heredia, as well as in Naranjo, La Garita, El Coyal and Poas in Alajuela, and the western San Jose suburbs of Escazu and Santa Ana.

There were no reports of injury or damage.

Incredible images of super typhoon Maysak from satellite

'Commands respect even from space,' Astronaut Samantha Cristoforetti says

Super Typhoon Maysak as seen from space, March 31, 2015.
Super Typhoon Maysak — which left at least five people dead after slamming into the Micronesian island of Chuuk — is expected to weaken as it approaches the Philippines, forecasters say. But it looked plenty powerful Tuesday, when astronauts aboard the International Space Station captured some incredible images of the enormous storm.

Italian astronaut Samantha Cristoforetti took several photos of the typhoon Tuesday, when Maysak's maximum sustained winds were 160 mph.

Mystery earth-shaking booms rattle central New Jersey residents

Image
Mysterious, earth-shaking booms have been reported in recent weeks by dozens of Bordentown and Hamilton residents, and authorities are at a loss to explain them. The most likely culprit, Joint Base McGuire-Dix-Lakehurst, says it wasn't them. While the military base routinely hosts artillery training on weekends and warns residents in advance, the mystery booms have come at odd hours and on weekdays when the range is inactive.

The latest boom jolted residents at 10 p.m. Monday. A closed Facebook group for Bordentown Township residents lit up with people asking each other, "Did anyone just feel that loud rumble? Was in the garage and the garage doors both rattled hard and I could feel the rumble under my feet," was one of a dozen replies. A similar online conversation unfolded on March 19 after the noise was heard around 9 p.m. Another series of reports occurred on March 17, a Tuesday. Some have reported hearing several booms in succession during the span of an hour.
