A 5.6-magnitude earthquake has occurred in Romania, the US Geological Survey reports.

Romania Hit by 5.6-Magnitude Earthquake, USGS Says
https://sputniknews.com/europe/20160924/1045651653/romania-hit-strong-earthquake.html

The epicenter of the earthquake was located at a depth of about 88 kilometers (55 miles), 7 kilometers west of Nereju in Romania’s Vrancea County, USGS said. Nereju is situated about 145 kilometers (90 miles) north of Romania’s capital, Bucharest.

The quake occurred at about 23:11 GMT on Friday. There were no immediate reports of damages or casualties.

A magnitude 6.5 earthquake has occurred off the coast of southern Philippines

6.5-Magnitude Quake Hits Off Philippines Coast
https://sputniknews.com/asia/20160924/1045651546/strong-magnitude-philippines-earthquake.html

A strong earthquake of magnitude 6.3 struck off the Philippine's Mindanao island on Saturday but was not expected to cause any significant damage, the Philippines' seismic agency said.

The U.S. Geological Survey said the quake, initially reported as a magnitude 6.5, struck at 6:53 a.m. (22:53 GMT on Friday) and was centered 71 miles (114.26 km) east of Davao on Mindanao. It was a deep tremor, 43 miles (69 km) below the seabed, and was not expected to cause a tsunami, the Pacific Tsunami Warning Center said. A magnitude 6.3 quake is considered strong and is capable of causing severe damage, but Renato Solidum, head of the Philippines' seismic agency, said the effects of this one would be mitigated by its location and depth.

There are no recently active volcanoes on the peninsula just south of Reykjavik - most are to the east, such as Krafla, Grimsvötn and Hekla, but the Reykjanes Ridge is part of the SW rift zone, so obviously a place where volcanism could occur. The Reykjanes Ridge is known to have submarine volcanism off the coast of Iceland, with young lava flows discovered in 1992 after seismic swarms. There are many geothermal prospects in this part of Iceland - part of the energy infrastructure of the island nation - along with known basaltic fields. The last known eruption on the of the rift system was in 1879, although there have been numerous eruptions noticed since humans arrived on Iceland in the 9th century, especially at the excellently named submarine Reykjaneshryggur. An eruption in 1830 produced a VEI 3 eruption that might have formed a temporary island. A number of suspected submarine eruptions may have occurred along the Reykjanes near Iceland since 1879. {See a great summary of more eruptions in Iceland in the comments below from Cat Dynamics' Stein Siggurdsson.}

The tremors of this earthquake even reached Belarus, and on its territory it was registered as an 3-magnitude earthquake. Which is very rare for this country.

The exact links between series of tremors and major quakes is still difficult to establish, however this article sheds some interesting lights on recent seismic events at the southern tip of the San Andrea fault line:

'Big One' Looms As Quake Swarm Strikes Southern California "In The Worrry Zone"

http://www.zerohedge.com/news/2016-09-30/big-one-looms-quake-swarm-strikes-southern-california-worrry-zone

Just five months ago, experts warned that "the springs on the San Andreas system have been wound very, very tight. And the southern San Andreas fault, in particular, looks like it’s locked, loaded and ready to go." And now, as The LA Times reports, a rapid succession of more than 200 small earthquakes began rupturing near Bombay Beach, at the southern tip of the San Andreas fault, continuing for more than 24 hours.

The temblors were not felt over a very large area, but, as The LA Times continues, they have garnered intense interest — and concern — among seismologists.

It marked only the third time since earthquake sensors were installed there in 1932 that the area had seen such a swarm, and this one had more earthquakes than the events of 2001 and 2009.


The quakes occurred in one of California’s most seismically complex areas. They hit in a seismic zone just south of where the mighty San Andreas fault ends. It is composed of a web of faults that scientists fear could one day wake up the nearby San Andreas from its long slumber.

The San Andreas fault’s southernmost stretch has not ruptured since about 1680 — more than 330 years ago, scientists estimate. And a big earthquake happens on average in this area once every 150 or 200 years, so experts think the region is long overdue for a major quake.

The swarm actually increased the likelihood of a much more major quake in Southern California, at least temporarily.

According to the U.S. Geological Survey, for the seven-day period following Tuesday, the chances of a magnitude-7 or greater earthquake being triggered on the southern San Andreas fault are as high as 1 in 100 and as low as 1 in 3,000. The chances diminish over time.

Experts said it’s important to understand that the chance of the swarm triggering a big one, while small, was real.

“This is close enough to be in that worry zone,” seismologist Lucy Jones said of the location of the earthquake swarm. “It’s a part of California that the seismologists all watch.”

An earthquake measuring 5.2 on the Richter scale struck off the Alaskan coast on Sunday, the US Geological Survey (USGS) reported.

Alaska Hit by 5.2-Magnitude Earthquake – USGS
https://sputniknews.com/world/20161002/1045914476/alaska-coast-earthquake.html

The quake occurred at 22:07 GMT on Saturday at a depth of 20.9 kilometers (about 13 miles), 236 kilometers (147 miles) south of False Pass, a city in the Aleutian Islands, Alaska, according to the USGS.

No information on casualties or damage from the quake has been provided yet.
