A magnitude 6.3 earthquake has struck northeast of Baghdad. It has been felt in Iraq, Kuwait, and northern Iran.

The quake hit the Iran-Iraq border region and had a depth of 10 kilometers, according to the European-Mediterranean Seismological Centre (EMSC).

The EMSC reported that the quake was widely felt more than 500 kilometers away from its epicenter.

Comment: Sputnik reports the number of injured has reached 361:
"The number of people, who asked for medical treatment, amounts to 361," Kolivand said, quoted by the Fars news agency.

Earlier media reports said that people had been injured in the cities of Gilan Gharb, Sarpol Zahab and Qasr-e Shirin.

The European-Mediterranean Seismological Center (EMSC) said that the Iraqi-Iranian border region had been hit by the 6.3-magnitude earthquake. The tremors were registered at 16:37 GMT, 163 kilometers (over 100 miles) northeast of the Iraqi capital of Baghdad and 20 kilometers southwest of the Iranian city of Sarpol Zahab.

Iran has faced several powerful quakes recently. Last year, a disastrous 7.2-magnitude quake killed and wounded hundreds. Earthquakes are common in mountainous Iran, due to the convergence of four major tectonic plates in the region.


Earthquake at 6.1 magnitude strikes off Colombia coast

An earthquake measuring 6.1 magnitude struck off the Colombian coast on Saturday, and while there was no major tsunami threat, there was a possibility of tsunamis along the nearby coast, the European earthquake monitoring agency EMSC and the Pacific Tsunami Warning Center said.

The quake epicenter was 36 km (22 miles) southeast of Mountain, Colombia, and at a depth of 10 km (six miles).


Seismic records show Newfoundland was literally shaking from vicious windstorm

Giant waves in Canada

Seismometer in St. John's shows how intense Thursday's winds were

The waves crashing into the rugged shoreline of Newfoundland and Labrador this week led to waves of a different kind.

The squiggly black lines produced by a Natural Resources Canada seismometer show the seismic activity of a vicious windstorm that whipped across the province on Wednesday and Thursday.

The wind and waves were so strong, the island was shaking.

"What we saw over the past 48 hours was quite a dramatic change in [activity]," said John Cassidy, an earthquake seismologist with Natural Resources Canada.

"It was very noticeable and in our seismic data, our plots, it just jumped off the page. You could just see that shaking."

Comment: The windstorm that struck Newfoundland and Labrador was the "most intense storm" on the planet, according to a meteorologist in Gander. Wild, whipping winds gusting upwards of 130 km/h caused huge waves, delays, cancellations and closures across the province reports CBC.

According to the Weather Network the effects of the incredibly strong low pressure system that moved through Atlantic Canada would cause more than ripples across the Atlantic Ocean this week, causing giant waves to track towards Europe and Africa.

6.7-Magnitude undersea earthquake off Fiji, but no tsunami

A 6.7-magnitude earthquake struck off the coast of Fiji Monday, the United States Geological Survey said, but it was too deep to cause any damage.

It was centred 534 kilometres (331 miles) deep and 283 kilometres east of the capital Suva where residents said they did not notice any shaking.

The Pacific Tsunami Warning Center said there was no tsunami threat from the tremor which occurred at 9:25 am (2025 GMT Sunday).

The area is prone to deep undersea earthquakes and was hit with a 7.8-magnitude tremor two months ago.

The quake, at a depth of 33km (20 miles), was centred 161km (100 miles) east of Kira Kira in the Solomon Islands.

The Solomon Islands, a nation of hundreds of islands in the South Pacific, has many World War Two-era sites.

The earthquake, which struck at 3.26am (GMT), was reviewed to a magnitude 6.2 and a revised depth of 10.6km (6.5miles).

Affected areas include Kirakira, the provincial capital of the Makira-Ulawa Province in the Solomon Islands.

The earthquake's epicentre was 132 km (82.3 miles) west of the city, which has a population of 11,222.

It is located on the north coast of Makira, the largest island of the province.

The area is known for its stunning natural beauty and ample beaches.

Comment: The USGS also registered a strong and shallow (10.0 km depth) M6.3 earthquake hit Southern East Pacific Rise on November 15, 2018.

Better Earth

Seismic study reveals huge amount of water is dragged into Earth's interior

under water
Slow-motion collisions of tectonic plates under the ocean drag about three times more water down into the deep Earth than previously estimated, according to a first-of-its-kind seismic study that spans the Mariana Trench.

The observations from the deepest ocean trench in the world have important implications for the global water cycle, according to researchers in Arts & Sciences at Washington University in St. Louis.

"People knew that subduction zones could bring down water, but they didn't know how much water," said Chen Cai, who recently completed his doctoral studies at Washington University. Cai is the first author of the study published in the Nov. 15 issue of the journal Nature.

"This research shows that subduction zones move far more water into Earth's deep interior - many miles below the surface - than previously thought," said Candace Major, a program director in the National Science Foundation's Division of Ocean Sciences, which funded the study. "The results highlight the important role of subduction zones in Earth's water cycle."

Comment: When we consider that major seismic activity has been risen by 2000% since the 1900s, are there any implications for the water on our planet?

Don Vitale had just walked into his house Tuesday evening when he heard a boom that sounded like a thunderstorm in the distance.

Then, a few minutes later, he heard a louder boom, and a pan on the stove rattled.

Vitale, who moved into his Carroll Township home about six years ago, wondered what it was. Then a neighbor called him: "Did you hear that?" Vitale said that he did.

"That's an earthquake," the neighbor told him.

It's been 10 years since an earthquake swarm rattled the Dillsburg area of northern York County. It started with a 2.0 tremor on Oct. 5, 2008, and the booming and rattling occurred periodically until early 2010. The tremors were centered in an area along Old York Road and Brandon Lane in Carroll Township.
