The earthquake struck 25 kilometres south of Gisborne, but was felt across the island just one day after a deadly volcano eruption on White Island
A strong 5.3-magnitude quake shook New Zealand's North Island, just hours after a lethal volcanic eruption killed five and left eight others missing. No damage or casualties have been reported following the latest tremor.

The quake struck at a shallow depth of some 25km (15 miles) around Gisborne on Tuesday, about 150km (93 miles) south of the recently erupted submarine volcano on White Island.

While local news reports said the seism could be felt in neighboring towns - including Cambridge, Hunterville, Dannevirke and Wellington - there are currently no reports of damage or injuries, nor any danger of a tsunami, according to Gisborne Civil Defense Manager Wiremu Tamati.

M3.2 earthquake rattles homes in Somerset, England

somerset quake
An earthquake has struck in the west of England, causing homes to shake in several villages, the British Geological Survey has said.

The 3.2 magnitude quake's epicentre was recorded near the town of Bridgwater in Somerset, the BGS confirmed.

Residents reported the "whole house rattled", with another another saying there was a "big rumble and [the] house [was] given a definite shove".

The quake hit at 22:49 GMT at a depth of three miles (5km), the BGS said.

'Bed shake'

Comment: Bridgwater is 121 miles (2 hours by car) from the Surrey fracking operation, and even further away from the one in Blackpool, where unusual but likely fracking-related quakes have been occurring with a worrying regularity. It's worth noting that also recently there was an unusually strong earthquake in France that caused a crack in the Earth's crust, leaving scientists puzzled.

A powerful earthquake has hit Albania in the middle of the night, forcing people to run into the streets. Dozens of people have been reported injured and several buildings collapsed, while others appeared to crack.

The 6.4-magnitude quake struck between the port town of Durres and the capital Tirana, at a depth of 10km (6.2 miles), according to the US Geological Survey.

Witnesses said residents were rushing out of their houses in panic, but an unknown number of people could still be trapped inside buildings.

One person has died after jumping from a building, Defence Ministry spokesperson confirmed.

Officials said that the most damage was seen in Durres, while at least 50 people in Tirana had to be hospitalized.

Rescue crews with excavators searched for survivors trapped in toppled apartment buildings and hotels Tuesday after a powerful pre-dawn earthquake in Albania killed at least 18 people and injured more than 600.

The magnitude-6.4 quake was felt across the southern Balkans and was followed by multiple aftershocks, with several above magnitude 5. In nearby Bosnia, another temblor with a preliminary magnitude of 5.4 struck southeast of the capital Sarajevo, causing only minor damage.

The quake in Albania knocked down apartment buildings and hotels while people slept, and rescue crews worked into the evening to free people believed trapped. There was no indication as to how many people might still be buried in the rubble, as neighboring countries and European Union nations sent search-and-rescue crews to help.

Local television stations showed footage in the early hours after the quake of a young boy being rescued from a collapsed building in the coastal town of Durres, 33 kilometers (20 miles) west of the capital Tirana. An excavator moved a broken slab of concrete and the boy cried and shouted in pain as local men pulled mangled reinforcement bars out of the way trying to try to free his leg from the rubble.

Hours later, live TV footage showed people cheering as another child was found alive in a collapsed building in Durres where a body had been located earlier. In total, 43 people had been rescued from the rubble of buildings by Tuesday evening.


Health Minister Ogerta Manastirliu said more than 600 people had been treated for injuries, including nine hospitalized with life-threatening injuries.

"It is a dramatic moment where we should preserve calm, (and) stay alongside each other to cope with this shock," Prime Minister Edi Rama said.

The U.S. Geological Survey said the quake, which struck just before 4 a.m. local time, had an epicenter 30 kilometers (19 miles) northwest of the capital, Tirana, at a depth of 20 kilometers (12 miles). Scores of aftershocks were recorded, including three with preliminary magnitudes of between 5.1 and 5.4.

The worst-hit areas were Durres, where 11 of the dead were found in collapsed buildings, and the northern town of Thumane, where another five bodies were pulled from the rubble, the Defense Ministry said. In total at least three hotels, a residential villa and an apartment building collapsed in Durres, and one apartment building in Thumane.

One person died after jumping from his home to escape in Kurbin, 50 kilometers (30 miles) north of the capital, while another person was killed on a road that collapsed in the northern town of Lezha.

"Search and rescue work continues at all sites where buildings have collapsed," Defense Minister Olta Xhacka said in a televised statement. "But these are extremely difficult operations, where you have to work slowly because there is a high risk of further collapse, endangering not only residents, but also those trapped, and the rescuers themselves."

Seismologist Rrapo Ormeni of Albania's Institute of Geosciences, Energy, Water and Environment, said a 6.4 quake was considered a strong one.

"Damage at the epicenter will be considerable because of its high energy, the magnitude it has," Ormeni said. "Such quakes are felt in a wider area due to (their) major depth and magnitude. It has been felt all around the territory of our country but also abroad, up to Bulgaria, Bosnia, Italy and other (countries)."

The quake was also felt in neighboring Kosovo, Montenegro, North Macedonia, Greece, and parts of southern Serbia.

Authorities called on people in the most affected areas to stay out of their homes and avoid driving to allow emergency vehicles free access. Many residents reported cracks in their apartment walls.

All government agencies were on alert and "intensively working to save lives at the fatal spots in Durres and Thumane," Rama said. About 400 soldiers were setting up tents in Durres and in Fushe Kruje near Thumane in the north to house survivors left homeless by the quake.

Rama said neighboring countries, the European Union and the United States had offered help. By Tuesday evening, rescue teams from neighboring Kosovo, Montenegro, Italy, Greece and Romania had arrived.

Serbia, North Macedonia, Croatia, Hungary, Germany, France, Estonia, Turkey and the Czech Republic also offered help, while the EU delegation to Albania said additional EU assets were on standby should they be needed.

"My thoughts are with the victims and all the people affected by the disaster," EU Commissioner for Humanitarian Aid and Crisis Management Christos Stylianides said.

At least three apartment buildings and the power distribution station were damaged in Thumane, knocking out power in the morning. The electricity supply was restored later in the day.

An earthquake in September in roughly the same area damaged hundreds of homes.
Update: wsbtv.com on November 28 has this AP report:
Hopes are fading of finding anyone else alive beneath the rubble of collapsed buildings in Albania two days after a deadly quake struck the country's Adriatic coast, with the death toll rising after more bodies were pulled from the ruins overnight.

Prime Minister Edi Rama on Thursday put the death toll at 39, after authorities said six more bodies were recovered from the northwestern town of Thumane, and another two from the port city of Durres, 33 kilometers (20 miles) west of the capital Tirana. More than 650 people were injured in the 6.4-magnitude earthquake that struck before dawn Tuesday.

Authorities say the search operation has ended in Thumane, with no more people believed to be missing in the collapsed buildings there. It continues, however, in Durres.
Update: Global News carries this latest report by AP on November 30:
Search for Albania earthquake victims ends as death toll rises to 50

The search and rescue operation for earthquake survivors in Albania has ended, the prime minister said Saturday, with the death toll at 50 and no more bodies believed to be in the ruins.

Prime Minister Edi Rama said preliminary figures showed more than 1,465 buildings in the capital, Tirana, and about 900 in nearby Durres were seriously damaged in Tuesday's 6.4-magnitude pre-dawn quake.

About 2,000 people were injured. One woman remained in a coma, according to health officials.

Preliminary figures estimate at least 4,000 people are homeless.


About 2,500 people from damaged homes have been sheltered in hotels. Others have been taken to neighboring Kosovo or have moved to eastern areas of Albania.

The prime minister has pledged all homeless will be in "stronger homes" in 2020.


The first seriously damaged building has been demolished, and a dozen others are expected to follow. Assessment experts from Greece, France, Italy, Hungary, Bulgaria, Lithuania and Latvia are involved.

A new draft law will sentence all investors, architects and supervisors to seven to 15 years in prison for violating construction norms. That and corruption in Albania's burgeoning building industry have been blamed for much of the quake's effects.

The government has set up financial compensations for families of the dead, including 1 million Lek ($9,000) per family, special pensions for elders and scholarships for children.

Greek island of Crete hit by 6.0-magnitude earthquake - One day after deadly Albania quake

Crete earthquake map

A 6.0-magnitude tremor rattled the Greek holiday island of Crete this morning and was felt on the southern mainland, a day after tremors were felt across south-eastern Europe
A powerful undersea earthquake has rattled Greece's holiday island of Crete and was felt in the southern mainland.

The 6.0-magnitude tremor this morning left the 'whole island shaking' and houses trembling 'dramatically', witnesses said.

Experts said there were 10million people living in areas where the quake was felt, but there were no initial reports of damage.

'It was a major earthquake, the whole island shook but fortunately so far no damage has been reported,' Crete regional governor Stavros Arnaoutakis told state TV.

One witness at Efthymi in Crete said: 'It went on for a long time. I was outside and I could here the rails on the balconies creaking.'

'Strongest I have ever felt. House shook dramatically, scary ... felt that it wouldn't stop. A very long few seconds!' said another, 30 miles from the epicentre.

With more than 100,000 small to medium aftershocks in Southern California since July experts are wondering when not if the BIG ONE will come

Graph
On the 4th of July 2019, Independence day, a magnitude 6.4 quake rocked Surles Valley, in Southern California, two days later a much more powerfull magnitude 7.1 struck the Ridgecrest area just a few miles away from the Surles Valley quake. Since then, more than 100,000 small to medium aftershocks, known as "swarmageddon," have hit the same area, including a mag 5.5, a mag 5.4 and a mag 5.0, which begs the question when not if will Southern California receive THE BIG ONE?

Since 2015, the Pacific Ring of Fire has been rattled by nearly 600 major quakes, (mag 6 or higher), see map here. Incredibly the Californian Coast has recorded just 3 major quakes in the same period and Oregon 2. The odds of this happening must be very high and surely the West Coast has to be long overdue for the big, it has to be!

To some, the "swarmageddon" 40 miles east of downtown Los Angeles has brought fear that a bigger threat was coming. To others, as long as they don't feel a shake, it is easy to just put it out of their minds. California has small quakes all the time — a magnitude 3 every other day, on average, according to the LA Times. But not all of them act the same, and some bring more danger than others. As officials install more seismic sensors as part of the state's early warning system, experts are getting an increasingly better look at California's smaller earthquakes. According to The Daily Mail, It's reminiscent of activity near the San Andreas Fault three years ago that had some scientists on edge for a possible large triggered earthquake.

Shallow 6.1 magnitude quake rocks off eastern Indonesia, no tsunami alert issued

quake map
A shallow and strong earthquake measuring 6.1 magnitude struck off eastern Indonesia's West Papua province on Saturday evening, but no tsunami alert was issued, the meteorology and geophysics agency said.

The quake jolted at 7:11 p.m. Jakarta time (1211 GMT) with the epicenter at 280 km northeast Tambrauw of the province and a depth of 10 km under sea bed, official in charge at the agency Abdul Rosid said.

"There (is) no potential of tsunami from happening so that we did not issue a warning," he told Xinhua over phone.

Indonesia is prone to quake for its position on the quake-impacted zone so-called "the Pacific Ring of Fire."
