Fresh shallow earthquake of magnitude 6 rocks Papua New Guinea

earth
An earthquake measuring 6 on the Richter Scale hit Papua New Guinea on Wednesday, officials said.

The fresh earthquake was felt just two days after 7.5 magnitude earthquake hit the area.

The earthquake triggered landslide which left at least 31 people dead and another 300 injured.

As per the US Geological Survey (USGS) website, the fresh earthquake hit at a depth of 10 kms.

The earthquake was felt at 2:45 local time.

No casualty has been reported so far.

This region is located on the so-called Pacific Ring of Fire.

This region is known for intense seismic and volcanic activity.

3.2 magnitude quake rocks Northern England shaking houses - the second to strike in 2 weeks

MAPPED: The quake's epicentre was on the edge of Cumbria's famous Lake District park

MAPPED: The quake's epicentre was on the edge of Cumbria's famous Lake District park
An earthquake has hit Cumbria, shaking the north of England.

The tremor had a magnitude of 3.2, the British Geological Survey said. While that is relatively weak, it can be enough to cause some damage to buildings.

Today's tremor is the second earthquake to hit the UK in as many weeks. Earlier this month, an earthquake near Swansea caused some confusion and problems, with shakes and noises spreading across the south-west.

Comment: As noted in: UK struck by 21 earthquakes in 50 DAYS including biggest in 10 years
Following last week's 4.6 magnitude earthquake in the UK, which was felt from Cornwall to Liverpool, a British Geological Survey tweet stated that, "Events of this magnitude only happen in the UK every 2-3 years."

Actually, there have been about 7 similar-strength quakes in the UK in the last 3 years alone...

22 May 2015 - A 4.2 magnitude earthquake 'causes homes to shake' in Kent, UK
25 May 2015 - Magnitude 3.0 earthquake recorded in North Wales
29 Jan 2015 - Britain's second earthquake in 48 hours strikes in East Midlands
7 Mar 2016 - Earthquake 'shook houses' in south-east England
3 Jan 2017 - 3.9 magnitude tremor strikes off UK coast - biggest quake for nearly a decade
4 July 2017 - Earthquake recorded off Shetland was largest in UK for nine years
5 Aug 2017 - Scottish Highlands are rocked by their biggest earthquake for 30 years

We are seeing a marked increase in seismic activity around the world lately, could it be related to scientists' predictions that major earthquakes for 2018 due to slowdown in Earth's rotation?
Whether earthquakes, volcanoes, sinkholes or landslides, there appears to have been a surge in activity recently:

A British Geological Survey chart shows the seismic activity during the UK earthquake last week
SHOCKING figures show there have been 21 earthquakes in the UK in the last 50 days, including the biggest in ten years, with the majority striking Wales.

The news that Brits are living on shaky ground comes after a 4.6 quake struck in Wales last week, and was reported to be the strongest to have hit the UK in 10 years.

The British Geological Survey has registered the specific location of the quake to be the village of Cwmllynfell near Swansea.

BGS figures show that four others struck in Cwmllynfell the same day.

The 4.6 quake at 2:31pm was followed by a 1.8 quake at 2.35pm, a 1.2 quake at 3.09pm, a 1.5 quake at 4.27pm and a 2.2 quake at 11.17pm.

The most recent quake to send shockwaves across our shores struck in Llanfechell in Wales on February 18.

It measured just 1.1 on the richter scale.

Out of the 21 quakes 10 of them were in Wales, with an assortment of villages that make up the area of Llanwenog feeling a 0.9 magnitude quake on January 11, and the village of Llangybi experiencing a 1.0 earthquake on January 6.

There were three earthquakes in England with Shropshire feeling a 1.5 quake on February 10, and Cumbria feeling a 1.0 quake January 29.

Comment: Following last week's 4.6 magnitude earthquake in the UK, which was felt from Cornwall to Liverpool, a British Geological Survey tweet stated that, "Events of this magnitude only happen in the UK every 2-3 years."

Actually, there have been about 7 similar-strength quakes in the UK in the last 3 years alone...

Earthquake swarm rattles San Francisco Bay Area

Epicenter of a magnitude 3.6 earthquake Friday in the East Bay area.
Several magnitude 2 and 3 earthquakes rumbled through the San Francisco Bay Area on Friday. It's the latest seismic activity to add to a swarm of 60 earthquakes greater than magnitude 1 to hit the Danville area in the past week.

The largest in the sequence, a magnitude 3.6 earthquake, came at 12:19 p.m. Friday. The U.S. Geological Survey received reports from more than 1,000 people who said they felt the quake, extending from the East Bay and into San Francisco. The quake was quite shallow, less than a third of a mile under the surface of the earth.

A magnitude 2.8 aftershock was felt two minutes later.

Earthquake swarms like the one that began on Feb. 16 in the Danville area have been common over the past few decades, occurring in 1970, 1976, 1990, 2002, 2003 and 2015. They occur in the San Ramon Valley corridor along Interstate 680 between Walnut Creek and the Dublin and Pleasanton areas, said U.S. Geological Survey research geologist Belle Philibosian.

The Calaveras fault runs right along the San Ramon Valley. In the Danville area, the fault zone transitions and steps over to the Concord fault, which continues north into Concord, Philibosian said. There is a complex zone of small faults in this transition area.

While the San Andreas and Hayward faults are well known to many in the Bay Area for their seismic risk, the Calaveras and Concord faults also pose a substantial risk. The Calaveras fault is as long as the Hayward fault, for instance, and can produce a magnitude 7 earthquake, Philibosian said.

Comment: Some other earthquake swarms recorded from around the world recently include:

According to experts with the US Geological Survey, the latest swarm began on February 8 in a region roughly eight miles northeast of West Yellowstone, Montana – and, it’s increased dramatically in the days since
A new swarm of earthquakes has cropped up at the Yellowstone supervolcano, with more than 200 small temblors detected in the last 10 days alone.

According to experts with the US Geological Survey, the latest swarm began on February 8 in a region roughly eight miles northeast of West Yellowstone, Montana - and, it's increased dramatically in the days since.

But for now, scientists say there's no reason to worry.

While the earthquakes are likely caused by a combination of processes beneath the surface, the current activity is said to be 'relatively weak,' and the alert level at the supervolcano remains at 'normal.'

Comment: We're seeing a marked increase in various kinds of geological activity lately, could it be related to scientists' predictions that major earthquakes for 2018 due to slowdown in Earth's rotation?

Shallow magnitude 6.1 earthquake rattles large swathes of Mexico

Earthquake seismograph
A STRONG 6.1-magnitude earthquake has rattled large swathes of Mexico, sending people fleeing into the streets fearing for their lives.

The powerful earthquake struck at a depth of 10 km at 12.56am local time (6.56am GMT), according to the US Geological Survey.

The epicentre was 43 km (27 miles) east of Oaxaca with shockwaves felt as far as Mexico City, USGS said.

Earthquake alarms were sounded in Mexico City - home to almost nine million people - giving residents time to evacuate their homes.

There are no immediate reports of damage to buildings, injuries or deaths.

Taking to Twitter, one wrote: "In Mexico City the earthquake alarms went off and gave us approximately 30 seconds to get out. We could feel it. It seems everything is ok."

The tremor comes just 48 hours after a 7.2-magnitude earthquake hit south-western Mexico, damaging buildings but causing no deaths.

Pictures posted to Twitter show anxious residents standing in the streets after the alarm was raised in the early hours of Monday morning.

EPICENTRE: The quake struck eight miles from Swansea city centre
A massive earthquake has struck Wales with tremors felt from Cornwall to Liverpool.

The 4.2 magnitude quake occurred near Swansea, south Wales, around 2.30pm at a depth of six miles.

Residents across the UK - from Bristol to Cornwall - have reported tremors in its aftermath.

Comment: A Sott.net reader wrote in to tell us that she felt it too:
I felt this tremor, nothing major, just felt like a the house jolted.
The British Geographical Survey says an event of this magnitude only happens in the UK every 2-3 years. Actually, there have been about 7 similar-strength quakes in the UK in the last 3 years alone...
