Geoscience Australia registered a shallow M6.0 earthquake (depth 0 km) south of Kermadec Islands at 09:13 UTC on September 7, 2015. USGS is reporting M6.4 at a depth of 35.4 km (22 miles).

According to the USGS, epicenter was located 191 km (119 miles) SSE of L'Esperance Rock and 725 km (450 miles) NE of Whakatane, New Zealand.

There are no people living within 100 km (62 miles) radius.

USGS issued green alert for shaking-related fatalities and economic losses. There is a low likelihood of casualties and damage.

Overall, the population in this region resides in structures that are resistant to earthquake shaking, though some vulnerable structures exist.

At 08:46 UTC today, a very deep earthquake registered as M6.1 by Geoscience Australia hit south of Fiji islands. The agency is reporting depth of 573 km (356 miles). USGS reported this quake as M5.3 at a depth of 547.3 km (340.1 miles). Epicenter was located 451 km (280 miles) SSW of Ndoi Island, Fiji and 673 km (418 miles) WSW of Nuku'alofa, Tonga, according to the USGS.

CT scan of Earth links deep mantle plumes with volcanic hotspots

University of California, Berkeley, seismologists have produced for the first time a sharp, three-dimensional scan of Earth's interior that conclusively connects plumes of hot rock rising through the mantle with surface hotspots that generate volcanic island chains like Hawaii, Samoa and Iceland.

Essentially a computed tomography, or CT scan, of Earth's interior, the picture emerged from a supercomputer simulation at the Department of Energy's National Energy Research Scientific Computing Center (NERSC) at the Lawrence Berkeley National Laboratory.


While medical CTs employ X-rays to probe the body, the scientists mapped mantle plumes by analyzing the paths of seismic waves bouncing around Earth's interior after 273 strong earthquakes that shook the globe over the past 20 years.

Previous attempts to image mantle plumes have detected pockets of hot rock rising in areas where plumes have been proposed, but it was unclear whether they were connected to volcanic hotspots at the surface or the roots of the plumes at the core mantle boundary 2,900 kilometers (1,800 miles) below the surface.

A 4.3 magnitude earthquake has hit the wildfire zone in north central Washington.

The quake, which was six miles deep, hit 26 miles east of Okanogan and 25 miles north of Grand Coulee at 9:42 a.m. Tuesday, according to the Pacific Northwest Seismic Network.

KIRO 7 meteorolgist Morgan Palmer said an earthquake of that depth was considered shallow and was likely felt as a jolt.

The Pacific Northwest Seismic Network asks if you felt the earthquake, to fill out the form here.

COMPTON, Calif., Aug. 31 (UPI) -- No injuries or major damage was reported Monday after earthquakes rattled cities in California, Oklahoma and Oregon.

Around noon local time, a 2.9-magnitude earthquake rattled a location two and a half miles southwest of Compton, Calif. This report comes after news of a 2.6-magnitude earthquake that struck at 5:11 a.m. local time Sunday along the Hayward Fault in California's East Bay. Local residents reported feeling the quake, which is the latest in a series of rumbles along the fault scientists said could be precursors to a large temblor coming soon, KRON in San Francisco reported.

A shallow magnitude 3.5 earthquake was reported Saturday morning 11 miles from Fort Bragg according to the U.S. Geological Survey. The temblor occurred at 1:13 a.m. Pacific time at a depth of 1.9 mile.

According to the USGS, the epicenter was 30 miles from Ukiah 63 miles from Clearlake and 71 miles from Healdsburg.

In the past 10 days, there have been two earthquakes of magnitude 3.0 or greater centered nearby.

Scientists studying swarm of earthquakes in Northern Nevada - 5,700 since last July

Scientists at the Nevada Seismological Laboratory say there has been a "swarm" of more than 5700 earthquakes in northwestern Nevada since last July. They include 21 4.0 temblors.

In 2008, the community of Mogul, west of Reno, also experienced an earthquake swarm.

Graham Kent is Director of the lab on the University of Nevada-Reno campus. He says the number of tremors in that swarm pales in comparison to this one.

"A magnitude 5.0 was the largest and a couple fours's and a bunch of three's and you look back at it and go 'wow!' that was hardly anything."

Kent said this kind of seismic activity is rare anywhere. He says the location of the swarm, which is below an antelope preserve, makes it a perfect place to study earthquake behavior.

"This is a great petri dish. So, now we have this kind of gold-medal swarm going and it doesn't affect a lot of people. So, what we can learn from this, hopefully we can apply the next time there's a swarm underneath a community."

More than 200 quakes 3.0 and stronger have been measured in the Sheldon National Wildlife Refuge since last July.

Seven of them were 4.5 or stronger.

Tremors were felt in several parts of India after an earthquake hit Nepal on Sunday. The fresh quake struck 89 km east of Kathmandu. According to The National Seismological Centre in Kathmandu, the quake, measuring 5.1 on the Richter scale with the epicentre at Dolakha was recorded at 2.47 pm (local time).

The US Geological Survey in a statement noted that the "earthquake magnitude was 5.0 and it occurred near Namche Bazar at 09:02:09.00 UTC on 23 August, 2015."

The tremors were felt in Delhi, following which people rushed out of their homes. Mild tremors also were felt in parts of Bihar, West Bengal and Sikkim.

A devastating earthquake measuring 7.8 on the Richter scale on 25 April had killed roughly 9,000 people and injured more than 20,000 in Nepal.

Hawkkey Davis' latest video compilation of extreme weather events (and general environmental chaos) from the past month or so.

The Solomon Islands, Alaska's Aleutian Islands, the Bay Area, Indonesia, Queensland and Maryland are rocked by earthquakes; Reunion Island (the site of the alleged MH370 'wreckage' found earlier this month) and Mexico by volcanoes. The Queensland quake was the biggest in a century. Flash floods in Arizona, northwest China, Iran, Pakistan, Florida, India, Myanmar, Colorado, and Argentina. Wildfires in France, Spain, Montana and California. The Dead Sea tourism industry is threatened by unprecedented sinkholes. All this, plus storms, tornadoes, sand, fireballs, record-breaking heat and more!

The tremor registered a 4.0 magnitude on the Richter scale and woke many California residents with a start this morning

Residents of San Francisco are pretty accustomed to experiencing tremors.

But even the most jaded of Californians were shaken this morning when a 4.0 tremor rocked through the city, waking many locals.

A weatherman was mid-report when the quake struck and was caught on film reacting as the studio clearly shook.

As he tries to steady himself he can be heard saying: "Oh my goodness! We have an earthquake!"

At first he appears slightly amused but as the tremor continues unabated he starts to look more alarmed and adds:

"This is a good one!"
