Minor damages after earthquakes 6.2 and 5.8 hit Ecuador coast

Two earthquakes shook the coastal area of Ecuador on Friday, leaving several structures damaged.

A first 6.2 magnitude earthquake hit the city of Guayaquil at 8:40 a.m. local time and was felt strongly in other provinces. It was recorded to have a depth of 47.11 kilometers.

The earthquake occurred 20 minutes before a simulation exercise was planned in that city to prepare citizens on how to deal with these types of emergencies.

On the same day, at 11:23 p.m. local time, a 5.8 magnitude earthquake hit the city of Balao in the same province, Guayas. The quake was closer to the surface, with 8.4 km of depth. No deaths have been reported.

Fracking Earthquakes: Government sponsored scientist reveals link and cover up

Fracking Earthquakes: Government sponsored scientist reveals link and cover up
Hydraulic fracturing is a natural gas extraction method that has become extremely controversial for its environmental impacts. Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside. Water, sand, and chemicals are injected into the rock at high pressure, which allows the gas to flow out to the head of the well. Wastewater produced from this process is highly toxic and filled with a variety of chemicals.

In many cases, people who live near fracking sites have been able to set fire to the water and air that comes through their pipes. It has also been found to contaminate drinking water. Unfortunately, fracking is still somewhat popular publicly because people know very little about it and it is also popular politically because all of the politicians have a hand in it.

Due to an increased prevalence of seismic activity in the vicinity of fracking areas, many activists have pointed that this process may cause earthquakes as well. While environmentalists have been hoping to raise awareness about this problem for years, new testimony from one of the country's top seismologists gives us a glimpse into why the scientific community has been largely silent about this issue.

Tsunami waves observed after 7.0 earthquake hits near France's New Caledonia

A magnitude 7.0 earthquake has struck in the Pacific near the overseas French territory of New Caledonia, the US Geological Survey (USGS) reports. Tsunami waves have been observed after the quake, the Pacific Tsunami Warning Center (PTWC) reports.

The quake was centered 82 km (51 miles) east-northeast of Tadine, on Mare Island, which has a population of over 5,600. The epicenter was 10 km (6 miles) deep. The numbers have been revised by USGS from earlier reports, which placed the epicenter 68 km from Tadine and 25 km deep, and reported its magnitude as 7.3.

The PTWC has warned of "hazardous tsunami waves" possible for coasts within 300 km of the epicenter, which puts the Loyalty Islands archipelago, with a population of over 17,000, within range. It later issued a message saying tsunami waves "have been observed."

Shallow 6.4 magnitude earthquake strikes near New Caledonia

An earthquake of magnitude 6.4 struck in the Pacific Ocean, 74 kilometers (46 miles) east of the Loyalty Islands, New Caledonia on Sunday.

The quake struck this morning about 45 miles east of the Tadine, in the Loyalty Islands.

The United States Geological Survey (USGS) reported the tremor at 8:25 pm in the evening, or 9.25am 25 GMT, at a shallow depth of 13km (8 miles).

The Pacific Tsunami Warning Centre said in a statement that a destructive Pacific-wide tsunami was not expected and there was no tsunami threat to Hawaii.

The quake was initially recorded as 6.6 magnitude, but is now being reported as 6.4.

Scientists predict upsurge in major earthquakes for 2018 due to slowdown in Earth's rotation

Scientists say number of severe quakes is likely to rise strongly next year because of a periodic slowing of the Earth's rotation

Scientists have warned there could be a big increase in numbers of devastating earthquakes around the world next year. They believe variations in the speed of Earth's rotation could trigger intense seismic activity, particularly in heavily populated tropical regions.

Although such fluctuations in rotation are small - changing the length of the day by a millisecond - they could still be implicated in the release of vast amounts of underground energy, it is argued.

The link between Earth's rotation and seismic activity was highlighted last month in a paper by Roger Bilham of the University of Colorado in Boulder and Rebecca Bendick of the University of Montana in Missoula presented at the annual meeting of the Geological Society of America.

Comment: This is what we've been saying for years, though in a different form: our idea was that the current slowdown in rotation is more 'unique' than a multi-decade event - more like a multi-millennium event.

The first quake hit near Soledad, Calif., at 5:17 p.m. with a magnitude of 2.9 and a depth of 5 kilometers. About two hours later, a second quake, with a 3.2 magnitude and a depth of 5 kilometers, shook Soledad once more. At 8:09 p.m., a 3.8 quake of the same depth followed.

Shallow 6.3 magnitude earthquake hits Tibet

A magnitude 6.3 earthquake has hit southern China near the border with India, the United States Geological Survey (USGS) reports.

The quake hit at a shallow depth of 10 kilometers (6.2 miles), some 58km from the Nyingchi prefecture, with a population of almost 200,000 people. No casualties or property damage was immediately reported.

The quake, initially reported as magnitude 6.7, hit the Tibet area, one of the most seismically active spots on Earth. The boundary between the Indian and Asian tectonic plate lies below the Himalayan-Tibetan region, with their collisions resulting in powerful earthquakes.

The region saw one of the most powerful earthquakes in the past century in 1950. Known as the Assam-Tibet earthquake, the 8.6 event killed some 4,800 people and caused destruction in both India and China.

A 5.4 magnitude earthquake that was South Korea's second-strongest in decades damaged infrastructure, injured dozens of people and left about 1,500 homeless, officials said Thursday.

No deaths have been reported since the quake rattled the southeastern coastal region around the port city of Pohang on Wednesday afternoon.

As of Thursday morning, 1,536 people had been forced to evacuate their homes and 57 people were injured, the Ministry of the Interior and Safety said in a statement.

More than 1,000 houses and dozens of other buildings and cars were damaged or destroyed, and cracks and other damage were found in military facilities, bridges, port facilities and water supply facilities. Media images showed crumbled walls piled on damaged cars, broken windows and cracks in buildings.
