EMSC is reporting M8.0 at a depth of 10 km (6.2 miles). Tsunami warnings, watches and advisories were issued following the quake. Over the next 3 hours, the USGS registered more than 20 aftershocks with magnitudes ranging from 2.5 to 5.3.
The epicenter was located 260.2 km (161.7 miles) SE of Chiniak (population 47) and 576.7 km (358.3 miles) S of Anchorage (population 291 826), Alaska, United States.
There are no people living within 100 km (62 miles). Some 14 000 people are estimated to have felt 14 000 light shaking.
Après l’introduction de nouvelles sanctions contre lui,
Pyongyang a déclaré vouloir «se venger» des États-Unis. La Corée du Nord a promis
d'introduire des contre-mesures sérieuses en réponse aux sanctions des
États-Unis, relate la chaîne SkyNews.
«Nous
nous vengerons mille fois des États-Unis et des actions ignobles et illégales
commises contre notre pays et notre peuple», déclarent des autorités
nord-coréennes.
Par ailleurs, Pyongyang indique que Washington essaye de
saper le fondement de la Corée du Nord.
«S'ils
croient que ce sera sans danger pour eux parce qu'ils se trouvent de l'autre
côté de l'océan, ils se trompent sérieusement», ont conclu les autorités
nord-coréennes.
Le
Conseil de sécurité de l'Onu a adopté une résolution durcissant les sanctions à
l'encontre de Pyongyang. L'initiative a été soutenue par les 15 États y
siégeant, dont la Russie et la Chine.
Ce document introduit notamment une interdiction sur les
exportations nord-coréennes de toute une série de minéraux et d'aliments, dont
le charbon, le fer, le plomb et les fruits de mer, ce qui réduira d'un milliard
de dollars les recettes de Pyongyang, qui atteignent actuellement près de trois
milliards de dollars. Le texte de cette résolution contient d'autres
restrictions, y compris des mesures à l'encontre de personnes morales et
physiques liées aux programmes nucléaires et de missiles de la Corée du Nord.
Ces sanctions font suite aux tests de missiles effectués par
Pyongyang.

------------------------------------------------------------ *** US EASTERN TIME *** ------------------------------------------------------------ Cities preparing for chaos during August 21 Solar Eclipse
Aug. 1, 2017: The upcoming solar eclipse, the first in 99 years to sweep across the continental United States, has so many fans that disaster-level preparations are being put in place because of the large number of travelers predicted to jockey for prime viewing spots.
As many as 7.4 million people are expected to pack into a 70-mile-wide band across the U.S. to watch the moon’s umbra block out the sun for a two-minute window on August 21, according to solar eclipse education website GreatAmericanEclipse.com. The path of totality, the area where the sun is completely blocked out, stretches from Oregon to South Carolina.
Since the beginning of 2017, hundreds of people have already reported loud vibrating noises around the world.
Here a small compilation and the most mysterious booms!

January 5 2017, UK – Really loud vibrating
noise heard and felt across Liverpool in the early hours.
Really strange noises were heard across
Liverpool in the early hours of this morning and there are now questions over
what it might be. Houses in Kensington were left shaking during 15
minutes, which one resident says could have been a horn on a ship. Others
living near the area also experienced the vibrating and heard the noise but
came up with different answers as to where the sounds were coming
from. Was it coming from the sky? Echo
January 4 2017, USA – Loud booms heard in
Grandview, Belton and Raymore, Missouri.
People across Grandview, Missouri reported
hearing a blast Tuesday night, with some people up to 13 miles away
saying they felt it. The explosion was followed by a series of smaller
ones.. all coming from a lawncare business, J.W.’s Lawn and Garden Equipment.
City officials say ammunition may have caused the blasts.
January 3, 2017, USA – Mystery boom rattles
houses in the Southington, Wolcott and Cheshire areas in Connecticut
Authorities investigated a loud bang after
residents reported the noise shook homes in the Southington, Wolcott and
Cheshire areas, but found no explanation. Southington police
said they received between 30 and 40 calls reporting a loud explosion around
10:30 a.m. Many of the calls came from the southwest part of town. Both the
police and fire departments responded to investigate the calls, but
found nothing out of the ordinary.
December 1 and December 6 2016 – Update:
January 6 2017, USA – Nighttime booms, house shaking, red flash in Louisana
skies – Fireball sonic boom?
In early December, weeks before New Year’s
fireworks could be considered a culprit, a pair of massive nighttime explosion
sounds rattled homes and startled residents across the Carrollton area.
The noise was loud enough that it sent New
Orleans police officers searching for gunshot victims, but they turned up
nothing — and a survey of other public agencies since then likewise leaves
the source of the sounds a mystery. Uptown Messenger
The mysterious booms are reported around the
World and most of them remain unsolved.
A "fire hose" of lava is pouring into the Pacific Ocean at Hawaii Volcanoes National Park after the recent collapse of a large section of lava called a delta, or bench.
HAWAII VOLCANOES NATIONAL PARK (BIVN) - The
Hawaiian Volcano Observatory's Scientist-in-Charge, Tina Neal, talks about the
26-acre delta that suddenly fell into the ocean on New Year's Eve.
HAWAII VOLCANOES NATIONAL PARK – Tina Neal,
Scientist-in-Charge of the USGS Hawaiian Volcano Observatory, talks about the
New Year’s Eve lava delta collapse at the Kamokuna ocean entry inside the
Hawaii Volcanoes National Park. Neal’s presentation was part of a special
“After Dark In The Park” event kicking off January’s Volcano Awareness Month.
On December 31, nearly all of the 26-acre lava
delta suddenly fell into the sea, along with more than four acres of older
coastal cliff area, which included the former lava viewing site. The viewing
area within the Hawaii Volcanoes National Park was closed for two days
following the incident and was reopened Tuesday.
The January 3 talk marked 34 years and counting
for the eruption at Pu‘u ‘Ō‘ō.
We will have more from Neal’s presentation,
which included a brief description of Kilauea’s East Rift Zone eruption,
including the June 27 lava flow and the current 61g flow to the ocean, as well
as the lava lake at the summit.

Up to 12 inches of rain below 8,500 feet is expected, and massive amounts of snow — up to 6 feet — above that elevation. A fourth, colder storm two days behind will drop yet more heavy snow. “It’s a once-in-10-year event,” said Zach Tolby, a meteorologist with the National Weather Service in Reno. “It’s the strongest storm we’ve seen in a long time, the kind of setup we look for to get significant flooding.”
The White House has published a 25-page report
on ‘National Near-Earth Object Preparedness Strategy,’ detailing preparations
in the event that a celestial object such as a ‘killer asteroid’ is found to be
on a collision course with Earth.
The report was written by the Interagency
Working Group (IWG) for Detecting and Mitigating the Impact
of Earth-bound Near-Earth Objects (DAMIEN). The document's purpose is to
"seek to improve our Nation's preparedness to address the hazard
of near-Earth object (NEO) impacts by enhancing the integration
of existing national and international assets and adding important
capabilities that are currently lacking." It outlined seven strategic
goals, including to improve the detection and characterization of NEO's,
to improve modeling and predictions of their behavior,
to develop methods to deflect and disturb them, to develop
emergency procedures in an impact scenario, to establish impact
response and recovery procedures, to leverage and support international
cooperation in the event of a potential NEO impact, as well
as to coordinate communications of related US government agencies and
establish a series of procedures if a potential NEO impact is detected.
The White House's
National Near-Earth Object Preparedness Strategy Report
The report comes in the wake
of December 2016 comments from NASA senior scientist Joseph Nuth
saying there is "not a hell of a lot we can do about" an
asteroid strike. Nuth claimed that if a NEO of significant size is found
to be on a collision course with Earth, there would not be ample
time to construct a deflection device.
In August 2015, NASA published a report saying
that all known Potentially Hazardous Asteroids have a "less than a
0.01% chance of impacting Earth in the next 100 years." However,
it is always possible that a previously undetected "killer asteroid"
could appear. The B612 Foundation, a NEO-hunting nonprofit, says that there are
"1 million smaller asteroids that might only wipe out a city or
perhaps collapse the world economy" that NASA has not identified.
The report identifies potential NEO impacts
as a low-probability, high consequence hazard that "[poses] a
significant and complex challenge." Even fairly small asteroids, such
as the Chelyabinsk meteorite that burst over Russia in 2013, can
cause enormous amounts of damage. A large one, such as the Chicxulub
meteor that struck Earth some 66 million years ago, could kill most life
on the planet's surface.
A swarm of more than 250 small earthquakes has
struck since New Year’s Eve near the California-Mexico border, causing unease
among residents and attention from scientists.
The earthquakes struck in the southern end of
the Brawley Seismic Zone, a seismically active region where tectonic plates are
moving away from each other and the Earth’s crust is getting stretched out “and
basically adding land,” said Caltech seismologist Egill Hauksson.
The Brawley Seismic Zone is particularly
important to watch because it is the region that connects the San
Andreas and Imperial faults, both of which can produce damaging earthquakes. The
seismic zone extends for about 30 miles from the city of Brawley, across the
Salton Sea’s southern half, and ends near Bombay Beach.
The Brawley Seismic
Zone, which stretches between Brawley to an area near Bombay Beach, is
important to watch because it is a region that connects the San Andreas and
Imperial faults, which can produce major earthquakes.
The southern Brawley Seismic Zone is close in
proximity to the Imperial fault. The Imperial fault has caused two major
earthquakes in recent decades.
In 1979, a magnitude-6.5 earthquake sent
violent shaking into El Centro, injuring 91 and causing so much damage to the
concrete Imperial County Services Building that it had to be demolished.
The magnitude-7.1 earthquake that hit El Centro
in 1940 claimed nine lives and swayed buildings as far away as Los Angeles.
Irrigation systems were damaged, and railroad tracks were left warped where
they crossed the fault.
Earthquake swarms that occur in the other end
of the Brawley Seismic Zone — to the north — could trigger a major event on the
San Andreas fault, one of California’s most dangerous, that could send
catastrophic shaking into Riverside, San Bernardino and Los Angeles counties.
More than 250
earthquakes have rattled the Brawley Seismic Zone near the California-Mexico
border since December 31, 2016 and it is not stopping.
In late September, one such swarm began in the
northern Brawley Seismic Zone, with three measuring above magnitude 4. That
event led the U.S. Geological Survey to warn that chances of a magnitude 7 or
greater earthquake on the San Andreas fault had risen as a result of the swarm.
Another swarm of small earthquakes, topping out
at magnitude 3.5, struck the town of Niland near the eastern shore of
the Salton Sea on Halloween.
Brawley Mayor Sam Couchman said the earthquakes
have placed the city of 26,000 on edge since Saturday afternoon.
“We’re just kind of listening to it, and
when you can hear it coming, it’ll rattle things. Last night, we had the rain,
the earthquakes, and the fireworks. All we needed were frogs and locusts.”
