According to seismologists, the earthquake occurred at a depth of 44 kilometres.

A 6.5-magnitude earthquake has struck near the coast of Northern Chile. No tsunami alert has been issued.

No possible casualties or damage have been reported so far.

​Chile is situated in the easternmost part of the Ring of Fire, a seismically active zone in the Pacific Ocean, where many earthquakes and volcanic eruptions occur, including powerful ones.

Comment: Less than a week ago a M6.2 earthquake hit Chile. There has been an increase in seismic activity worldwide recently.

Seismic activity near Yellowstone Lake has seen a big increase over the past 24 hours.
The southwest side of Yellowstone Lake, the largest body of water in Yellowstone National Park, is experiencing quite an uptick in seismic activity today, Thursday, September 10.

According to the United States Geological Survey (USGS), Yellowstone experiences about 1,500 to 2,500 located earthquakes per year, many occurring in swarms, or earthquakes that cluster in time and space. Most swarms are small, containing 10-20 earthquakes, and short, lasting for one to two days.

Today's seismic activity is a little abnormal in that as of 4 pm Thursday, 93 earthquakes, and counting, have occurred all within this area of Yellowstone Lake since Wednesday night, according to USGS data. All but seven of the earthquakes have been under 2.5 magnitude. None have reached 3.0 magnitude.

In the same area depicted in the map below, 108 earthquakes have been recorded over the past 30 days, including today's activity. That means only 15 earthquakes were recorded in the area before today.

The quake was felt at about 09:45 BST in the town of Leighton Buzzard
Carly Jan Smith, 31, in Dunstable, said it was "really strong" and lasted for about two seconds. Her whole room went from "side to side", she said.

The British Geological Survey said it struck just north of Leighton Buzzard.

Bedfordshire Police said there were no reports of injuries, although it had received a large number of calls.

Dr Richard Luckett, of the British Geological Survey, confirmed the quake, saying: "It was very minor on a global scale, but still quite large for the UK.

Shallow 6.2 magnitude earthquake rocks Vanuatu - 2nd of such strength in 28 hours

reader
Two strong earthquakes, within 20 minutes of each other, rocked the Vanuatu capital Port Vila this afternoon.

According to the United States Geological Survey website the first quake, which struck at 6:12pm, measured 6.2 on the Richter scale and occurred at a depth of 10 kilometres with its epicentre about 73 kms north north east of Port Vila.

The second measured 5.7 and hit at 6:29pm it was also at a depth of 10kms but its epicentre was a little closer at 75kms north north east of Vila.

Residents in Port Vila were shaken by quakes but so far there have been no reports of any serious damage.

The Pacific Tsunami Warning Centre reported there was no threat of a Tsunami from either quake.

Comment: Additionally this latest quake was the second magnitude 6.2 to strike near the island within 28 hours, see: Pacific 6.2M earthquake strikes off Vanuatu

It was also the fifth of magnitude 6 + recorded within 2 days across the planet: Earthquake of magnitude 6.3 strikes near Mindanao, Philippines - 4th such strong quake within 24 hours globally

An earthquake of magnitude 6.3 struck 82km east-northeast of General Santos in Mindanao, the Philippines, the US Geological Survey (USGS) said on Sunday (Sept 6).

The quake had a depth of 120.9 km, according to the USGS.

The Philippine Institute of Seismology and Volcanology (Phivolcs) said the offshore quake hit at a depth of 143 km, about 26km southeast of Don Marcelino town at 11.23pm local time.

Comment: This is the fourth magnitude 6+ quake registered within 24 hours across the planet - the other 3 being:

Magnitude 6.5 earthquake strikes northern coast of Chile - 3rd strong quake in 24 hours

The quake was followed by more than a dozen aftershocks -- including one with a magnitude of 6.1.

A magnitude 6.5 earthquake struck near the coast of Northern Chile on Tuesday, the GFZ German Research Centre for Geosciences said, with local news media reporting some damage and minor landslides in areas near the epicenter.

Chile's interior ministry said in a statement that mining companies operating in the area had not reported any issues in the 2-1/2 hours since the initial quake. GFZ has reported several aftershocks of magnitudes between 5.5 and 6.2.

Chile is the world's largest copper producer and most of its large operations are in Antofagasta region, more than 300 km (180 miles) north of the quake's epicenter.

Miner Antofagasta Plc told Reuters that its operations at Los Pelambres, the closest large deposit to the epicenter, some 379 km (236 miles) in a straight line, had not been affected.

Patricio Elgueta, a union chief at state miner Codelco's El Salvador mine 200 km (120 miles) north, said operations continued as normal.

Mine facilities and other infrastructure in Chile are built to withstand large quakes.

The interior ministry's National Emergency Office said there had been some localized power outages and landslides blocking roads.
