4.0-Magnitude earthquake rattles Los Angeles: Epicenter near airport

Los Angeles Airport

A 4.0-magnitude earthquake rattled Los Angeles early Monday morning centered in Lennox, a city two miles East of Los Angeles International Airport.

The 4.0 tumbler struck at 4:45 a.m. PT, though the robotic LA Quakebot earlier registered a 3.0-magnitude earthquake in the area at 4:18 a.m. and a 2.5-magnitude earthquake at 4:19 a.m. There have been no reports of major damage or injuries. LAX continues to operate as normal.

6.0-magnitude earthquake hits New Zealand's Gisborne

quake
An earthquake of magnitude 6.0 on the Richter scale jolted Gisborne city of New Zeland on Monday, the United States Geological Survey said.

The epicentre, with a depth of 10.0 km, was initially determined to be at 37.5205 degrees south latitude and 179.6745 degrees east longitude.

No casualties have been reported yet. On March 4, a powerful earthquake of magnitude 6.9 on the Richter Scale jolted Gisborne, New Zealand.

In 2011, a magnitude 6.3 quake hit the city of Christchurch, killing 185 people and destroying much of its downtown.

The earthquake was recorded at about 1:16 UTC. The epicentre of the tremor was located east of the islands. The focus lay at a depth of 10 kilometres.

A 6.6-magnitude earthquake has struck east of the South Sandwich Islands in the South Atlantic Ocean, according to the United States Geological Survey (USGS).
There have been no reports of injuries or damage as a result of the earthquake, as no people live on the South Sandwich Islands. No tsunami alert has been declared, the US National Tsunami Warning Centre stated.
The earthquake's epicentre was more than 1,810 kilometres from King Edward Point, a research station on South Georgia Island and is the capital of the British Overseas Territory of South Georgia and the South Sandwich Islands, according to the Indian National Centre for Seismology.

An earthquake with a magnitude of 6.0 jolted Fiji region at 15:11:18 GMT on Thursday, the U.S. Geological Survey (USGS) said.

The epicenter, with a depth of 597.77 km, was initially determined to be at 21.8731 degrees south latitude and 179.3414 degrees west longitude.

Comment: In the same region of the Pacific Ocean and a little over 5 hours earlier a huge 6.6 magnitude earthquake struck just off the Kermadec Islands.

Huge 6.6 magnitude earthquake strikes just off Kermadec Islands

graph
AN earthquake measuring 6.6 in magnitude has been recorded north-east of New Zealand, within the so-called Ring of Fire, the USGS has reported.

The tremor is the latest in a a series of 34 in the region in the last day, the USGS has said. It struck at a depth of 6.2 miles. There is currently no tsunami alert in force - but a series of quakes did trigger one earlier this month.

Seismic activity is commonplace in the region, located within the so-called Ring of Fire which stretches around the Pacific Basin.

On Monday, the American Geophysical Union tweeted: "An M8.1 #earthquake off the coast of #NewZealand triggered an estimated 300 #landslides on #RaoulIsland, the largest of the #Kermadec Islands.

Taal Volcano (taken October 26, 2020).
TAAL Volcano registered more earthquakes and emitted more gas over the past 24 hours, signs of a looming eruption, the state-run Philippine Institute for Volcanology and Seismology (Phivolcs) said on Wednesday.

Based on the Taal Volcano Network (TVN), 212 quakes, including 168 tremors with durations one to 20 minutes, and 44 low frequency volcanic earthquakes were recorded.

Some 1, 229 tons of sulfur dioxide were emitted by the volcano in Batangas province in the past 24 hours, according to Phivolcs chief Renato Solidum.

Solidum said with the volcano under Alert Level 2, an increased unrest may lead to an eruption and advised "all concerned to remain vigilant".

"The fact that we have volcanic tremors and prolonged background tremor recorded, higher than normal sulfur dioxide emission rate of 923 tons per day, slow but steady inflation of the volcano still indicates magmatic activity at shallow depth beneath the volcano," he said.

A 5.4 magnitude earthquake in Xinjiang Uygur Autonomous Region in northwestern China claimed the lives of three people, media reported on Wednesday.

The tremor occurred on Tuesday at 9:14 p.m. local time (0:14 GMT) about 100 kilometers (62 miles) away from Aksu county. The epicenter of the earthquake lay at a depth of 10 kilometers.

Seismologists recorded 10 repeated aftershocks, the strongest of them had a magnitude of 3.4.

As of Wednesday, three deaths have been registered as a result of the tremor. A total of 65 houses were also reported damaged or destroyed by the earthquake, 16 of which collapsed along with the roof.

Shallow 3.5 earthquake hits northwest France

quake
An earthquake of magnitude 3.5 occurred in the morning on Saturday 20 March 2021 at 10:22 am local time near Rennes, Ille-et-Vilaine, Bretagne, France, as reported by France's Réseau National de Surveillance Sismique (RéNaSS).

According to preliminary data, the quake was located at a shallow depth of 10 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.

Magnitude 7.2 earthquake rocks northeastern Japan

quake
A strong magnitude 7.2 earthquake struck off the coast of northeastern Japan at a depth of 60 km on Saturday evening at 6:09 p.m.

In Miyagi Prefecture, where at least one person was injured, the quake measured up to a strong 5 on the Japanese seismic intensity scale to 7.

Tsunami waves of up to 1 meter may have reached the Miyagi Prefecture coast shortly after 6:30 p.m., according to NHK. All tsunami warnings were lifted by 7:30 p.m.

Due to the tsunami advisory, the town of Watari in the prefecture issued an evacuation order covering 2,527 homes and 6,911 residents.

Two hundred homes in Kurihara, Miyagi Prefecture were without power, NHK said. The quake caused the Tohoku Shinkansen to suspend services. Services were expected to resume around 10 p.m.
