An earthquake measuring 6.0 on the Richter scale has been recorded off the east coast of Japan, Reuters reports, citing the United States Geological Survey (USGS).

The quake's epicenter was recorded out at sea and is located parallel to the Fukushima prefecture.

The nation's meteorological agency is reporting a depth of 10 kilometers, with the earthquake measuring at least 6.0 on local seismic recording equipment.

The snowy cone of Llaima volcano, Chile.
An unusual swarm of more than 600 earthquakes - never seen in years - has struck below Llaima volcano in Chile reports rio bueno noticias.

According to Sernageomin (Chilean National Geology and Mining Service) reported through Ovdas (Volcanological Observatory of the South Andes), a series of LP-type low frequency tremors, commonly associated with the dynamics of fluids inside the volcanic system, have been recorded at the volcano since Sunday 1 October.

Ovdas reported that despite the increase in seismic activity at the volcano, the accumulated energy is still considered low and the alert level remains at green. Llaima Volcano is one of the largest and most active volcanoes in Chile.

Volcanic and seismic activity appears to be increasing in the Pacific Ring of Fire.

An earthquake with a preliminary magnitude of 6.0 struck off northeastern Japan on Wednesday. There were no immediate reports of damage or injuries, and no risk of tsunami.

The Japan Meteorological Agency said the quake struck at 5:22 a.m. (8:22 GMT) off the Pacific coast of Iwate and Aomori prefectures at a depth of about 30 kilometres (20 miles). The U.S. Geological Survey measured the magnitude at 5.9.

It shook the same region hit by a deadly earthquake and tsunami in 2011. The shaking was felt in Tokyo, 570 kilometres (350 miles) southwest of the epicenter.

The USGS measured a 6.4 earthquake to the south of Fiji, and the southwest of Tonga, at 98 kilometres deep, 846km south east of Suva, at 1619 Fiji Time on 26 September 2017.
The Pacific Tsunami Warning Centre says there is no threat of a tsunami from a 6.4 earthquake which struck near Fiji and Tonga.

The US Geological Survery measured the quake, which occurred today at 1619 Fiji Time, at a depth of 98 kilometres.

According to disaster response authorities in Fiji, the quake's epicentre was 846km south east of Suva, which is just to the west of the Tongan trench.

The co-ordinates of the quake are 23.713°S 176.937°W.

A powerful 6.0-magnitude earthquake has struck off the coast of Papua New Guinea.
A 6.0-magnitude earthquake struck off Papua New Guinea on Tuesday, according to the United States Geological Survey, but no Pacific-wide tsunami warning was issued.

The tremor hit at a depth of five kilometres (three miles) near the sparsely-populated East New Britain region, some 210 kilometres southeast of the town of Kokopo, the USGS said.

The Hawaii-based Pacific Tsunami Warning Center did not issue a tsunami warning.

Earthquakes are common near Papua New Guinea, which lies on the 4,000-kilometre-long Pacific Australia plate.

It forms part of the "Ring of Fire", a hotspot for seismic activity due to friction between tectonic plates.

A magnitude 5.7 earthquake has struck off the coast of Chiapas, Mexico, according to the European Mediterranean Seismological Centre (EMSC).

The tremor hit at a depth of 60km on Sunday, EMSC reports. The epicenter lies 157km southwest of the city of Tuxtla Gutiérrez, the agency said.

There have been no immediate reports on destruction and casualties yet.

China detects 'natural' N. Korea earthquake - fears of nuclear test unfounded

A magnitude 3.4 earthquake, at a depth of 0 kilometers, was recorded near the Kilju area of North Korea Saturday. Although initial reports suggested it may have been the result of a nuclear test, it seems likely the quake was naturally occurring.

The quake occurred at approximately 08:30 GMT (16:29 local time) Saturday, CENC reported. Kilju is home to the Punggyeri nuclear site, where North Korea's sixth and largest nuclear test was conducted on September 3.

There were conflicting reports as to the strength of the quake, with South Korea's weather agency reporting that it measured 3.0 on the Richter Scale, as cited by the country's Yonhap news agency.

Is California next? Concerns increase as a series of killer quakes hit the Pacific 'Ring of Fire'

After a 6.1 magnitude earthquake hit New Zealand on Wednesday followed by temblors off the coasts of Japan (6.1), Vanuatu (6.4), and Indonesia (5.7) early Thursday morning, others along the Ring of Fire, including California, are wondering if they could be next. But, experts say offshore quakes happen in the region all the time, and go unnoticed
In the span of just 24 hours, a series of powerful earthquakes rocked several locations along the Pacific one by one this week, all in a seismic region known as the 'Ring of Fire' - and, others in its path, including California, are now wondering if they could be next.

Roughly 90 percent of the world's earthquakes occur in this belt, which loops from New Zealand to Chile, passing through the coasts of Asia and the Americas on the way.

Now, after a 6.1 magnitude earthquake hit New Zealand on Wednesday followed by temblors off the coasts of Japan (6.1), Vanuatu (6.4), and Indonesia (5.7) early Thursday morning, experts admit the Pacific is experiencing 'unusual' seismic activity, leaving the West Coast on edge.

But, this doesn't necessarily mean California or other areas of the West Coast will be affected by the events.

Earthquake warning sirens are currently sounding in Mexico City while the head of the city government has advised that emergency protocols have been activated following a 6.4 temblor in the city of Ixtepec in the southern state of Oaxaca.

Initial reports from the Mexican Seismological authority said the quake struck at 07:53 am local time at a depth of 10 kilometers with an epicenter approximately 12 km north of the City of Ixtepec. This is around 530km south of Mexico City.

In an update, the service downgraded it to a 6.1 magnitude earthquake, placing its epicenter seven kilometers west of the town of Union Hidalgo in Oaxaca at a depth of 75km.

So far there have been no reports of injuries, fatalities or damage, reports news outlet 24 Horas.

Comment: The earthquake in Mexico has had some eerie effects. This video was posted showing how the area was still reverberating from the quake, giving the appearance of the ground 'breathing'

The US Geological Survey says a new earthquake has struck Mexico with a magnitude of 6.2 and was centered in the southern state of Oaxaca.

That's the region most shaken by a magnitude 8.1 quake that hit last week.

It also swayed buildings in Mexico City, which is trying to recover from a magnitude 7.1 temblor that struck on Thursday, killing at least 295 people.

It's not immediately clear if the new quake caused damage or injury.

Comment: There was also a 5.8 earthquake off the Mexican coast about 2 hours prior to the above event according to Earthquake Track
