A powerful earthquake has struck the border area between Afghanistan, Pakistan and India, with tremors felt in Delhi and Islamabad.

The quake was intially measured at magnitude-6.6 and depth 210km by the USGS, though there were no immediate reports of casualties.

Reports from across South Asia described buildings swaying for more than a minute with tremors felt in the Pakistani city of Lahore some 630km from the epicentre.

Pakistani official Arif Ullah said the magnitude-7.1 quake was centered near Afghanistan's border with Tajikistan. Germany's GFZ Research Center for Geosciences set the quake's magnitude at 6.5.

Reports of mysterious tremors in eastern North Carolina attributed to sonic booms from military activity

Did you feel a bit of a shake Friday afternoon? You're not alone.

WECT received several emails and messages on social media about a possible tremor in the Myrtle Grove area, as well as in Leland.

However, the United States Geological Survey's website showed no earthquake activity in North Carolina.

Our First Alert meteorologists did manage to see what appears to be remnants of a sonic boom wave on radar just off the coast of the Cape Fear region.

Movement of water around the world contributes to Earth's rotational wobbles says NASA

Earth does not always spin on an axis running through its poles. Instead, it wobbles irregularly over time, drifting toward North America throughout most of the 20th Century (green arrow). That direction has changed drastically due to changes in water mass on Earth.

Using satellite data on how water moves around Earth, NASA scientists have solved two mysteries about wobbles in the planet's rotation -- one new and one more than a century old. The research may help improve our knowledge of past and future climate.

Although a desktop globe always spins smoothly around the axis running through its north and south poles, a real planet wobbles. Earth's spin axis drifts slowly around the poles; the farthest away it has wobbled since observations began is 37 feet (12 meters). These wobbles don't affect our daily life, but they must be taken into account to get accurate results from GPS, Earth-observing satellites and observatories on the ground.

In a paper published today in Science Advances, Surendra Adhikari and Erik Ivins of NASA's Jet Propulsion Laboratory, Pasadena, California, researched how the movement of water around the world contributes to Earth's rotational wobbles. Earlier studies have pinpointed many connections between processes on Earth's surface or interior and our planet's wandering ways. For example, Earth's mantle is still readjusting to the loss of ice on North America after the last ice age, and the reduced mass beneath that continent pulls the spin axis toward Canada at the rate of a few inches each year. But some motions are still puzzling.

Earthquake strikes major volcano in Iceland

There was a major earthquake on the northern edge of the Bárðarbunga volcanic craters at around midnight last night.

The quake measured 4.2 on the Richter scale and is therefore the largest quake to have hit the famous volcano since it stopped erupting in February last year.

According to Bjarki Fries, a natural disasters specialist with the Icelandic met office, the earthquake emanated from 3.5 kilometers underground. Around 15 aftershocks have already been measured, the most powerful of which was a 3.5 quake at 01.00 this morning.

Met office earthquakes specialist Martin Hensch told RÚV that there is no evidence of lava movements or of any eruption activity connected to the earthquakes, but that the situation will be monitored carefully. There were two quakes in the same location on April 3, measuring 3.4 and 3 on the Richter scale.

The recent eruption at Bárðarbunga, often known as Holuhraun, lasted from late August 2014 to late February 2015, and despite not affecting aviation or physically threatening any human settlements, it caused dangerous levels of pollution around Iceland and produced more new lava than almost any other eruption in Iceland since the Vikings first arrived.

Magnitude 6.7 earthquake strikes Vanuatu; THIRD large quake in region this week

An earthquake measuring 6.7 has struck the northwest of Vanuatu, the third large earthquake in the same region this week.

The United States Geological Service said the earthquake struck 109km west of Sola, in Torba province, at a depth of 33km.

The Pacific Tsunami Warning Centre said the quake posed no tsunami threat.

Thursday afternoon's quake came less than 24 hours after another 6.9 magnitude struck slightly to the west in Santo at a depth of 10km.

Another quake of the same magnitude struck the area on Sunday.

Swarm of small earthquakes hit northwestern Arizona

A series of small earthquakes swarmed the state's northwest corner after an initial magnitude 2.3 earthquake on the Arizona strip March 29, officials said Tuesday.

The earthquake that struck near Littlefield, Ariz., a community about 20 miles southwest of St. George, Utah, was the first of 18 small-magnitude tremors that lasted through Sunday, according to the Arizona Geological Survey.

The largest event was a 2.6 magnitude quake at about 8:36 a.m. Sunday. The Arizona Geological Survey has not reported any injuries or damage from the series of tremors.

While the amount of quakes to hit the area may seem unusual, Geological Survey researcher Michael Conway said the state has seen swarms before.

Conway said the area is "tectonically active," but this was the first time a swarm has been recorded in the northwest corner of the state, bordering Utah and Nevada.

"Active faults in the vicinity of the earthquake swarm include the Mesquite/Overton Arm," according to an Arizona Geological Survey statement. The area has extensive earthquake history.

Strong earthquake hits Indian ocean, south of Bandung, Indonesia

The earthquake, which struck at 9:45 p.m. on Wednesday, was centered 152 kilometers southwest of Tasikmalaya, or 163 kilometers south of Bandung. It struck about 10 kilometers deep, making it a shallow earthquake, according to BMKG, which is Indonesia's seismological agency.

BMKG, which measured the earthquake at a preliminary 6.1, said there was no tsunami threat as a result of the tremor. The earthquake was felt throughout parts of Java Island but there was no immediate word on whether it had caused any damage or casualties.

Indonesia is on the so-called 'Pacific Ring of Fire', an arc of fault lines circling the Pacific Basin that is prone to frequent and large earthquakes. In December 2004, a magnitude-9.1 tremor, one of the most powerful earthquakes ever recorded, struck off the west coast of Sumatra, unleashing a massive tsunami that struck scores of countries in the region and killed at least 227,898 people.

Magnitude 6.9 earthquake strikes northwest of Vanuatu

The earthquake struck 109km west-south-west of Sola, Vanuatu, USGS said.

An earthquake of magnitude 6.9 has struck near the Pacific island nation of Vanuatu, the US Geological Survey (USGS) says.

The earthquake struck 109km west-south-west of Sola, Vanuatu, at 6.58pm (NZT) at a depth of 33.7 km, the USGS said.

The Pacific Tsunami Warning Centre did not issue a Pacific-wide tsunami warning.

"Based on all available data a destructive Pacific-wide tsunami is not expected," the centre said.

A similarly-sized quake struck the same area on Sunday without causing any damage.

7.2 magnitude quake strikes off Vanuatu islands

A 7.2-magnitude earthquake rocked off Vanuatu in the Pacific on Sunday, the US Geological Survey said.

No casualties or damage have been reported.

The Vanuatu islands are part of the so-called Ring of Fire — a horseshoe-shaped region in the Pacific Ocean formed by volcanoes and tectonic faults. Ninety percent of all earthquakes occur in the Ring.

Strong 6.2 magnitude earthquake shakes Alaska, no tsunami warning

An earthquake with magnitude 6.2 occurred near Port Heiden,100 kilometers northeast of Chignik Lake, southwestern Alaska.

A strong 6.2 magnitude earthquake shook a lightly populated remote region of southwestern Alaska, the US Geological Survey that monitors quakes worldwide reported.

The quake struck at 0550 GMT on Saturday on the Aleutian arc some 654 kilometers southwest of Anchorage, and 100 kilometers northeast of Chignik Lake, Alaska.

The National Tsunami Warning Center said that no watch, warning or advisory would be issued for the quake.

"A tsunami is NOT expected to be generated by this earthquake," the Center said.

The earthquake epicenter was 58 miles below the surface, the Alaska Earthquake Center reported.

"One might think that Americans...would be better equipped with suspicion." Obviously some are, or they wouldn't be getting fired.
