The relatively strong tremor that threw into panic people in Bulgaria's capital Sofia and nearby Pernik is an aftershock of the 5.8-magnitude quake at the end of May, according to experts.

"What we experienced on Saturday is an aftershock of the earthquake of May 22 this year and has the same epicenter," Professor Nikolay Miloshev, director of the National Institute of Geography, Geophysics and Geodesy, Sofia, explained.

In his words it is not unusual that today's earthquake is related to the May tremor because it was very strong and even then seismologists predicted aftershocks may continue for months.

Saturday's earthquake was estimated as 4.5 on the Richter scale by the European Mediterranean Seismological Centre and as 4.2 on the Richter scale by the Geophysical Institute at the Bulgarian Academy of Sciences (BAS).

Kofu, Yamanashi Pref. - A 20-meter-long crack was found halfway up Mount Fuji in Yamanashi Prefecture after a 6.4-magnitude earthquake hit on March 15, 2011, centered around eastern Shizuoka Prefecture, local authorities revealed Tuesday.

They ruled out the possibility of an eruption.

"No abnormalities have been observed regarding Mount Fuji and the mountain shows no signs of an eruption," an official at the Meteorological Agency said, indicating the crack was caused not by volcanic activity but by the temblor.

At 8:13 Sunday morning a 4.4 magnitude earthquake hit central Labrador, about 150 kilometres south, southwest of Happy Valley - Goose Bay.

There were no reports of damage and none would be expected according to Steven Halchuk, a seismologist with Natural Resources Canada.

"An earthquake of this size is not large enough to cause any damage whatsoever, but if you were close to it you would feel significant shaking," Halchuk told CBC News.

Earthquakes in the area are rare occurrences, according to Halchuk.

"There is a scattering of earthquake activity that extends from the Gulf of St. Lawrence up through Quebec and Labrador past Happy Valley - Goose Bay [but] it's usually small. The last earthquake I can find of this size in the region happened about 50 years ago, in 1962 actually," said Halchuk.

3.1 and 3.9 quakes strike near The Geysers, California

Image
Two earthquakes in quick succession were reported Sunday afternoon near The Geysers, according to the U.S. Geological Survey.

The first was a shallow magnitude 3.1 earthquake two miles from The Geysers, according to the USGS. The temblor occurred at 5 p.m. Pacific time at a depth of 1.9 miles.

According to the USGS, the epicenter was four miles from Cobb, six miles from Anderson Springs, 26 miles from Santa Rosa and 74 miles from Sacramento.

The second was a shallow magnitude 3.9 earthquake three miles from The Geysers, according to the USGS. The temblor occurred at 5:01 p.m. Pacific time at a depth of zero miles.

Continuous earthquake activity recorded in El Hierro volcano

Fishing boats in La Restinga, El hierro Island, Canary Islands
There have not been great changes in El Hierro volcano. Currently no eruption has taken place. There are also no signs of magma movement on tremor plots on seismometers stations that are located on El Hierro Island. The dike intrusion in El Hierro volcano is continues, but at slower rate then before. But that it is continuing means there is continued risk of an eruption where the earthquakes are currently taking place. Currently the rate of earthquake is around 3 to 8 earthquakes during the hour. Most of the earthquakes are around ML1.5 to 3.4 in magnitude. Please note that I am missing all earthquakes with the magnitude of ML0.0 and up to ML1.5. So there might well be a lot more earthquakes taking place in El Hierro volcano then I am seeing on IGN web page.

Magnitude-4.3 Earthquake Rocks Northern California

A magnitude-4.3 earthquake hit just outside Fort Bragg in California on Sunday at about 5:05 a.m. PDT (8:05 a.m. EDT), according to the U.S. Geological Survey, or USGS.

Local police reported neither injuries nor significant damage were caused by the earthquake, the Associated Press said. At this time, no aftershocks have been reported by the USGS.

Quakes of magnitude 4.3 rarely cause significant damage, but they are quite noticeable and occasionally cause damage in areas with poor building codes. About 13,000 earthquakes of this size occur each year.

According to the USGS's listings, Sunday's earthquake is California's largest since early last month. Because California sits on several fault lines, the area is prone to earthquakes. Most quakes in the area, however, are rarely rated above magnitude 3.0, meaning they are normally too small to be felt.

A moderate 5.1 magnitude earthquake has struck the island nation of the Dominican Republic. The epicenter of the earthquake was 113 km (70 miles) W (260°) from San Cristóbal, San Cristóbal, Dominican Republic and just 128 km (80 miles) ESE (106°) from PORT-AU-PRINCE, Haiti. The earthquake had a depth of 19.9 km (12.4 miles) and may have caused some preliminary damages though reports coming in are scant in details.

Some people described the shaking as 'huge'.
North Islanders were again rattled by a strong earthquake yesterday, but experts say the tremor was not related to a much larger quake four days earlier.

GeoNet reported a magnitude 5.7 quake struck 10km south of Turangi at 12.50pm. The quake was 90km deep and, though police said there were no reports of damage, some residents said trinkets had been smashed.

It came four days after a magnitude 7 earthquake, centred at a depth of 230km and offshore from Taranaki, rattled residents from the Bay of Plenty to Canterbury, but caused little damage.

Shaken people took to social media and message boards yesterday to share their experiences, some describing the shake as "huge".
