Borneo buffeted by strong, shallow M6.0 temblor but no tsunami threat: USGS

AFP-JIJI
 
A strong 6.0 magnitude earthquake struck Indonesia early on Monday, the U.S. Geological Survey (USGS) said, but no immediate damage or casualties were reported.

The quake, which was relatively shallow, struck the northeastern corner of Kalimantan on the Indonesian part of Borneo island, 34 km (21 miles) north of the coastal city of Tarakan, according to the USGS.

The agency reported the quake hitting at a depth of 22 km.

Indonesia’s tsunami warning center said there was no potential for the quake to trigger tsunami. There were also no immediate reports of damage.

Magnitude-6.8 earthquake strikes Chile,Buildings Sway no damage reported



Magnitude-6.8 earthquake strikes Chile, no damage reported

earthquake


SANTIAGO, Chile (AP) — A strong magnitude-6.8 earthquake struck north-central Chile on Saturday, causing buildings to sway in the capital of Santiago, but there were no immediate reports of injuries or damage.

The U.S. Geological Survey said the quake struck at 4:31 a.m. about 29 miles (47 kilometers) southwest of Ovalle, a city 185 miles (300 kilometers) northwest of Santiago, at a depth of 22 miles (36 kilometers).

Chile’s Navy first alerted, but later discounted, the possibility of a small tsunami.
“The situation in the region of the epicenter is now in a state of normality,” Ricardo Toro, the head of Chile’s emergency services, said in a press conference.

A magnitude 6.8 earthquake shook central Chile Saturday with no damage or injuries reported so far. The tremor comes just two months after another quake hit the same area.

Buildings reportedly swayed in capital city of Santiago, but no tsunami alert has been issued. The U.S. Geological Survey said the earthquake struck 30 miles southwest of Ovalle, a city nearly 185 miles northwest of Santiago, at a depth of 22 miles.

A series of three earthquakes shook Arizona Sunday night. The epicenters were just north of Black Canyon City in central Arizona off Interstate 17.





4.1-magnitude Arizona earthquake shakes metro Phoenix

 

Residents reported shaking across metro Phoenix on Sunday night amid at least three quakes that struck near Black Canyon City.

 

 
A string of earthquakes north of Phoenix gave the Valley a rare jolt Sunday night, and the largest – a magnitude 4.1 just before 11:30 p.m. – rattled homes across the region.

The series of at least three Arizona earthquakes generated no reports of notable damage, but left people swaying or stunned from Black Canyon City, closest to the epicenter, to Camp Verde and across metro Phoenix as far as Queen Creek.

Michael Conway of the Arizona Geological Survey said Monday morning that scientists had not identified the causative fault line yet. Because the earthquake was small and did not rupture the ground, it will be hard to identify where it originated, Conway said.He also said there will be aftershocks over the next few days, many of them too small to feel.

(Reuters) - Magma levels are slowly rebuilding inside Mount St. Helens, a volcano in Washington state that erupted in 1980 and killed 57 people, although there was no sign of an impending eruption, U.S. scientists said.
The roughly 8,300-foot volcano erupted in an explosion of hot ash and gas on May 18, 1980, spewing debris over some 230 square miles and causing more than a billion dollars in property damage. Entire forests were crushed and river systems altered in the blast, which began with a 5.2 magnitude earthquake.
"The magma reservoir beneath Mount St. Helens has been slowly re-pressurizing since 2008," the U.S. Geological Survey said in a statement on Wednesday. "It is likely that re-pressurization is caused by (the) arrival of a small amount of additional magma 4 to 8 km (2.5 to 5 miles) beneath the surface."

According to new research, ongoing hydraulic fracking operations will only exacerbate seismic activity.

Fracking-linked earthquakes likely to worsen – seismologists

Published time: May 02, 2014 03:40

Ongoing hydraulic fracking operations will only exacerbate seismic activity, leading to heightened earthquakes in areas where wastewater is injected deep underground, according to new research.
To unleash natural gas, hydraulic fracturing - or fracking - requires large volumes of water, sand, and chemicals to be pumped underground. Scientists attending the Seismological Society of America (SSA) annual meeting said Thursday that this storage of wastewater in wells deep below the earth’s surface, in addition to fracking’s other processes, is changing the stress on existing faults, which could mean more frequent and larger quakes in the future.
Researchers previously believed quakes that resulted from fracking could not exceed a magnitude of 5.0, though stronger seismic events were recorded in 2011 around two heavily drilled areas in Colorado and Oklahoma.
“This demonstrates there is a significant hazard,” said Justin Rubinstein, a research geophysicist at the US Geological Survey (USGS), according to TIME magazine. “We need to address ongoing seismicity.”
Not all of the more than 30,000 fracking disposal wells are linked to quakes, but an accumulating body of evidence associates an uptick in seismic activity to fracking developments amid the current domestic energy boom.
The amount of toxic wastewater injected into the ground seems to provide some clarity as to what causes the earthquakes. A single fracking operation uses two to five million gallons of water, according to reports, but much more wastewater ends up in a disposal well.
