Cluster of small earthquakes shake New Zealand as M6.8 quake rocks Kermadec Islands

An earthquake expert says a cluster of small quakes which has rocked parts of the country is unlikely to be related to a major shake near the Kermadec Islands.

A Geonet spokesman said there is no definite way to tell but Kiwis should not think the shaking throughout the country is related to the Kermadec quake.

The spokesman also told the Herald there should be little concern the Kermadec quake would trigger a big quake in New Zealand.

"You can't make any guarantees but there's no reason to think this would trigger something on the Alpine Fault or any other major fault in New Zealand," the spokesman said.

A magnitude 6.8 earthquake struck south of the Kermadec Islands at 4.19pm and the Ministry of Civil Defence warned it could trigger a tsunami.

However, the Ministry was quick to quash any possibility of a tsunami impacting New Zealand as a result of the earthquake.

A strong 6.4-magnitude earthquake shook the southern Philippines on Saturday (Sept 8), sending frightened residents fleeing from buildings, officials and eyewitnesses said.

The quake struck off the coast of the southern town of Manay at about 3.16pm at a depth of 14km, the Philippine Institute of Volcanology and Seismology (Phivolcs) said in a statement. The institute said it expects the earthquake to have caused some damage but it and the local civil defence office said there were no immediate reports of serious destruction.

"A lot of people ran from their homes because a lot of items were falling inside," Phivolcs science researcher John Deximo told AFP.

A series of powerful earthquakes has struck the South American east coast, with Panama, Chile and Ecuador all suffering jolts of between 5.6 and 6.2 magnitude within less than an hour of each other.

Panama was hit by a 5.6-magnitude earthquake at 1:47am GMT. According to the US Geological Survey, its epicenter was located at a depths of 10km, some 15km from the small town of Yaviza.

Less than 30 minutes later, at 2:12am GMT, a powerful 6.2-magnitude jolt hit central Ecuador, some 94km (58 miles) south of the city of Ambato at a depth of 112km (69 miles).

So far, at least one person has been injured, Ecuador's authorities said, noting some damage to homes and reported landslides on roads. Power outages are also being reported. The jolts were felt as far away as the capital, Quito, and the city of Guayaquil. According to the Ministry of Risk Management, the jolts were felt the strongest in Cumanda, Chimborazo province.

A major earthquake with magnitude 7.8 (ml/mb) was detected on Friday, 101 kilometers (63 miles) from Suva in Fiji. The 7.8-magnitude earthquake was detected at 03:49:14 / 3:49 am (local time epicenter). The epicenter was at a depth of 608.59 km (378 miles). Exact location, longitude 179.3315° East, latitude -18.4935° South, depth = 608.59 km. A tsunami warning has been issued near Suva in Fiji (Does not indicate if a tsunami actually did or will exist). Event ids that are associated to the earthquake: us2000h9e2, pt18249001, at00pen5a4. Id of event: us2000h9e2. Global time and date of event 06/09/18 / 2018-09-06 15:49:14 / September 6, 2018 @ 3:49 pm UTC/GMT.

Nearby country/countries, Fiji (c. 876 000 pop) (That might be effected). Event epicenter was 102 km (63 miles) from Suva (c. 77 400 pop), 47 km (30 miles) from Levuka (c. 8 400 pop). Closest city/cities or villages, with min 5000 pop, to hypocenter/epicentrum was Suva, Levuka.

Earthquakes 7.0 to 7.9 may cause serious damage. There are an estimated 15 major quakes in the world each year. In the past 24 hours, there have been two, in the last 10 days two, in the past 30 days four and in the last 365 days six earthquakes of magnitude 3.0 or greater that have been detected nearby.

Another strong earthquake hits Japan - 2 dead, 143 injured - Collapsed buildings and massive landslides in Hokkaido

The earthquake turned this road into liquid in Sapporo, northern Japan
Though not a particularly strong earthquake for Japan, a magnitude 6.7 earthquake there today has caused extensive damage and reports of deaths are beginning to emerge. The quake struck northern Japan, while the US Geological Survey reports that it occurred at a depth of 39 kilometers.

Of course, a quake's magnitude on the Richter Scale doesn't tell us everything about its potential to cause damage. All kinds of waves are generated by earthquakes, and a combination of environmental and infrastructural factors will determine how much damage it causes on the surface.

Today's quake comes a day after Typhoon Jebi, officially the strongest typhoon to hit Japan in a quarter century, swept across the country's main island, further damaging infrastructure and causing at least 11 deaths. Japan underwent another major earthquake just two months ago, resulting in three deaths and leaving over 200 people injured.

In the following footage showing the moment the quake struck, note the now familiar 'earthquake lights' on the horizon. These are likely a plasma phenomenon related to powerful ground-to-sky electric discharge during intense seismic activity:

Magnitude 4.4 earthquake shakes Southern California

Two earthquakes have hit La Verne, east of Los Angeles
A magnitude 4.4 earthquake rattled a wide area of Southern California on Tuesday night. But there were no immediate reports of damage or injuries.

The temblor struck about 7:33 p.m. and was centered about three miles north of La Verne, a San Gabriel Valley city about 25 miles east of downtown Los Angeles, according to a preliminary report by the U.S. Geological Survey.

It was followed a minute later by a magnitude 3.4 quake.

The quake was about four miles deep, but it was felt sharply near the epicenter.

Vickie Carillo and her son were sitting on the couch of their La Verne home, watching "Jaws 2," when the quake struck. "It was like if somebody had grabbed it and was shaking the house," Carillo told the Los Angeles Times.

Carillo said she screamed. Her family picked up their two Jack Russell terriers and ran outside, where they joined about a dozen neighbors.

A powerful undersea earthquake measuring a magnitude 7.1 struck near New Caledonia in the South Pacific on Wednesday, creating small tsunami waves, the Pacific Tsunami Warning Center said.

The quake struck at a shallow depth of 10 km (six miles) some 372 km (230 miles) east of the New Caledonian capital Noumea. It was initially reported as magnitude 7.

The center said there was no Pacific-wide tsunami threat but added that waves 17 cm (7 inches) high reached the shores of the Loyalty Islands, 250 km (155 miles) east of the epicentre.

No damage was reported.

"We felt it and they felt it more strongly on the Loyalty Islands," Civil Defense spokesman Olivier Ciry told Reuters by phone from Noumea.

"But there is nothing to say. There is no damage, no tsunami and we don't expect anything else," he said.

An earthquake centered east-northeast of Anatahan in the Northern Mariana Islands rocked the region this morning at 8:35 a.m., the U.S. Geological Survey states.

The 6.4 magnitude earthqauke struck about 33 miles deep at about 99 miles east-northeast of Anatahan, the agency states. USGS downgraded the magnitude, which was initially assessed as 6.6.

The earthquake could was felt on Guam and lasted about 30 seconds, with two strong jolts.

The Offices of Guam Homeland Security and Civil Defense, in a release, said there were no reports made to 911 of damages or injuries from the earthquake.

At least two people were killed and 241 others injured when a 5.9-magnitude earthquake struck in western Iran's Kermanshah province early Sunday, government news agency IRNA reported.

The epicenter of the quake was 6 miles from Tazehabad and 19 miles from Javanrud. Both cities are close to the Iran-Iraq border. The earthquake struck at a depth of some 10 kilometers (6 miles).

Iran's Emergency and Natural Disaster Agency told state-run Press TV that five rescue teams have been sent to the area.

Press TV, an English-language television station in Iran, tweeted that people were rushed to the hospital, though there were no immediate casualty figures.
