A 6.2-magnitude earthquake struck Papua New Guinea today, the US Geological Survey said.

The quake hit just after 4pm local time at a depth of 19 miles some 75 miles south of Kokopo, the capital of PNG's East New Britain province, the USGS said.

Despite the earthquake strike close to the shore no tsunami warning was issued, authorities said.

Geoscience Australia senior seismologist Trevor Allen said coastal communities near the epicentre would have felt 'quite strong ground shaking' as the tremblor was close to the shore.

But, he said, the area was relatively sparsely populated and flexible building design locally helped limit exposure to damage from quakes.

6.0-magnitude earthquake hits off coast of Mindanao, Philippines

The island nation is located in a seismically active zone known as the Ring of Fire, which regularly endures both powerful and minor earthquakes.

A strong 6.0-magnitude tremor has struck 205 kilometres southeast of Davao, a city on the southern Philippine island of Mindanao, the European-Mediterranean Seismological Centre reported.

The earthquake occurred at a depth of 10 kilometres at 13:40 UTC. No casualties or damage have been reported so far.​ There has been no tsunami alert issued with regard to the seismic activity.

The Philippine Institute of Volcanology and Seismology measured the quake at 6.1 magnitude. It registered a series of six aftershocks measuring 4.6 magnitude and lower. The national agency said no damage was expected.

In December, at least seven people were killed as a result of a magnitude 6.8 tremor that hit the southern island.

A 6.3-magnitude earthquake jolted Bali resort island earlier Thursday, but there was no potential for tsunami, the meteorology and geophysics agency said.

The quake struck at 01: 12 a.m. Jakarta time Thursday (1812 GMT Wednesday) with epicenter at 69 km northeast Bangkalan of East Java province and the depth at 636 km under sea bed, Jerisman Purba, an official in charge of the agency, said.

"The center of the quake is very deep. It did not potentially trigger tsunami, so we did not issue a warning for that," he told Xinhua by phone.

Affected countries: Turkey and Greece

Earthquakes today have emerged around the Pacific Ring of Fire, where most of the world's seismic activity takes place. The United States Geological Survey (USGS) has recorded a total of 58 earthquakes, many of which touched down in clusters.

The world saw nearly 60 earthquakes today, most of which came in at middling magnitudes.

However, the USGS also recorded several potentially damaging higher magnitude tremors.

According to the organisation, today's biggest earthquake measured in at a magnitude of 5.8 and struck Greece earlier this morning.

The earthquake, one of six to strike the area from 1.30am today, rocked the Mediterranean sea to the east of Karpathos.

An earthquake with a magnitude of 6.0 jolted 70 km west of Kirakira, Solomon Islands, at 13:49:50 GMT on Wednesday, the U.S. Geological Survey said.

The epicenter, with a depth of 86.63 km, was initially determined to be at 10.3749 degrees south latitude and 161.2802 degrees east longitude.

Comment: This is the second M6+ earthquake to hit the region since a M6.3 struck on January 27. The recent uptick in seismic activity continues!

Shallow magnitude 6.1 aftershock hits near Cayman Islands - USGS

M6.1 earthquake hits off the Cayman islands on January 28 2020

A shallow 6.1-magnitude quake struck some 53 km off the coast of the Cayman islands at the depth of just 10 km. It came shortly after a powerful 7.7- quake off Jamaica triggered a tsunami warning across the Caribbean.

The Pacific Tsunami Warning Center (PTWC) said that it's unlikely the aftershock, which was reported at 21:55 GMT on Tuesday, would trigger any tsunami waves, but did not rule out the possibility outright in its initial statement.

"Based on all available data...there is no significant tsunami threat from this earthquake. However... there is very a small possibility of tsunami waves along coasts located near the epicenter," the PTWC said.

The initial magnitude of 6.5 reported by The US Geological Survey (USGS) was later downgraded to 6.1. The aftershock hit west of the first, 7.7-strong quake, that sent ripples across the region, prompting a tsunami alert for Mexico, Cuba, Jamaica, the Cayman Islands and several other countries. That tsunami warning was eventually lifted.

A tsunami warning has been issued for parts of the Caribbean after a huge earthquake struck.

Jamaica, Cuba and the Cayman islands were all said to be at risk.

The US Geological Survey said the 7.7-magnitude quake hit off the northwest coast of Jamaica, prompting the US Tsunami Warning Center to issue an alert.

It was so big that schools in Jamaica and buildings in Miami - 580 miles away - were evacuated.

Possible magma accumulation on Reykjanes peninsula, Iceland

Possible Magma Accumulation on Reykjanes Peninsula
Authorities have declared a state of uncertainty due to possible magma accumulation on the Reykjanes peninsula in Southwest Iceland. The aviation colour code has been raised to yellow for the region, which includes Keflavík International Airport. An earthquake swarm has been ongoing in the area and inflation has been detected in the last few days.

A statement from the Icelandic Met Office asserts that, while earthquake swarms are not unusual in the area, "[t]he fact that an inflation is occurring alongside the earthquake swarm is a cause for closer concern and closer monitoring." The inflation is occurring just west of Þorbjörn mountain, near the town of Grindavík, and is unusually rapid, around 3-4 mm per day. It has accumulated to 2cm to date and is most likely a sign of magma accumulation at a depth of just a few kilometres. It is not certain that magma accumulation is causing the inflation, but if such is the case, then, according to the Met Office, "the accumulation is very small."
