M6.3 earthquake hits Chile at intermediate depth, very strong shaking in Arica

– January 21, 2018

A strong earthquake registered by the CSN Chile as M6.3 hit northern Chile at 01:06 UTC on January 21, 2018 (22:06 local time, January 20). The agency is reporting a depth of 105.3 km (65.4 miles). USGS is reporting M6.3 at a depth of 110.8 km (68.8 miles); EMSC M6.4 at 110 km. The quake was preceded by M3.0 at 22:45 UTC, January 20.

According to the USGS, the epicenter was located 76.6 km (47.6 miles) S of Putre (population 0), 85.2 km (52.9 miles) ESE of Arica (population 185 999), Chile and 117.8 km (73.2 miles) SE of Tacna (population 280 098), Peru.

There are 230 000 people living within 100 km (62 miles) and less than 1 000 within 10 km (6.2 miles).

According to the USGS, some 128 000 people are estimated to have felt moderate shaking.

However, CSN Chile reports very strong shaking in Arica and in the village of Codpa. Strong shaking was reported in Cuya, Pocon Chile and Putre.


Major 7.3 magnitude earthquake outside Peru sparks tsunami warning: One dead, 20 injured

Zoie O’Brien – January 14, 2018

A 7.3 magnitude earthquake has hit the coast of Peru in the Ring of Fire region, sparking tsunami fears. The massive quake hit 31km south-southwest of Acari, according to the US Geological Survey (USGS).

One person died and 65 people have been injured after the seismic movement which had an epicenter in Lomas.

Houses in the Arequipa region have been destroyed and electricity is out.

In the town of Yauca, Justo Palomino Yucra, 55, was crushed to death.

Provincial mayor of Caravelí, Santiago Neyra confirmed the death following the earthquake.

The Pacific Tsunami Warning Centre said tsunami waves are possible within 300 km of the epicenter along the coast of Peru.

National Weather Service officials also claimed there is a tsunami risk, around 186 miles from the centre.


Will 2018 Bring Massive Earthquakes? Earth Could Enter High Seismic Activity Period

– January 1, 2018

As the new year dawns on us, the first horrible news is already out for the year. Scientists are predicting a massive increase in the number of large earthquakes in 2018.

Scientists have found an alarming link between slowing seismic activity of Earth and an increase in the number of surface tremors. There are periods where minute fluctuations in the speed of Earth’s rotation cause a change in the length of days and nights. These changes add up and cause a period of measurably slower speed in Earth’s rotation around its own axis. It is believed these changes could trigger increased seismic activity.

A team of researchers from University of Colorado (CU) in Boulder found during the past 100 years, Earth’s slowdowns have correlated surprisingly well with periods with a global increase in magnitude 7.0 and larger earthquakes.

Usefully, the spike, which adds two to five more quakes than typical, happens well after the slow-down begins.

“The Earth offers us a 5-years heads up on future earthquakes, which is remarkable,” says Roger Bilham, professor at CU and lead author of study along with Rebecca Bendick at the University of Montana in Missoula in a study related released on journal Science.


Major M7.6 earthquake hits off the coast of Honduras, small tsunami observed

A very strong and shallow earthquake registered by the USGS as M7.6 hit north of Honduras at 02:51 UTC on January 10, 2018 (20:51 local time, January 9). The agency is reporting a depth of 10 km (6.2 miles). EMSC reported M7.6 at a depth of 15 km (9 miles). Minor sea level fluctuations have been observed and may continue during the next couple of hours.

According to the USGS, the epicenter was located 201.9 km (125.5 miles) NNE of Barra Patuca (population 2 758) and 245.2 km (152.4 miles) N of Puerto Lempira (population 4 856), Honduras.

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

Some 58 000 people are estimated to have felt moderate shaking and 3 318 000 light.

Minor tsunami waves have been observed (up to 30 cm / 0.98 feet) and may continue over the next few hours, PTWC said 04:48 UTC.

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


Powerful earthquakes to ravage Earth in 2018 as planet’s rotation temporarily slows

Jeff Parsons – January 2, 2017

The world is entering a period of higher seismic activity this year that will bring more earthquakes with it, scientists have predicted.

While that’s undoubtedly bad news for those living within affected areas, the ability to accurately predict when and where earthquakes will occur is growing all the time.

This prediction comes from the fact that the Earth is currently experiencing a periodic slowdown of its rotation.

Historically, these slowdowns have coincided with peak times for earthquakes and seismic activity.

“So far we have only had about six severe earthquakes [in 2017]. We could easily have 20-a-year starting in 2018,” said Dr Roger Bilham from the University of Colorado.


Strong Earthquakes Hit San Francisco And Mount St. Helens And Experts Warn They May Be Foreshocks For ‘Something Larger’

Michael Snyder – January 4, 2018

Just when it seemed like things may be settling down, two very unusual earthquakes have hit the west coast within the past couple of days.  A 4.4 magnitude quake struck Berkeley, California just prior to 3 AM on Thursday morning, and a 3.9 magnitude earthquake hit Mount St. Helens in Washington state on Wednesday.  Overall, there have been 68 earthquakes in the vicinity of Mount St. Helens since New Year’s Day, and there have been a total of 629 earthquakes in the state of California within the last 30 days.  Could it be possible that all of this activity is leading up to a historic seismic disaster on the west coast?

The 4.4 magnitude earthquake along the Hayward fault very early on Thursday jolted people out of bed all over the San Francisco area

A strong 4.4 magnitude earthquake has rattled the Bay Area shortly before 3 a.m.

USGS is reporting the quake was centered in Berkeley. On KRON4’s real time earthquake map it shows the epicenter.

The quake struck at 2:39 a.m. and was centered near the Claremont hotel. The earthquake had a preliminary depth of 8 miles, according to USGS.

This wasn’t a soft and gentle earthquake that everyone kind of laughs about after it is over.

Earthquake hits Indonesia’s Java island, deaths reported

Associated Press – December 15, 2017

JAKARTA, Indonesia — A strong earthquake shook Indonesia’s most populous island of Java on Friday night, collapsing buildings and killing at least 1 person.

The quake struck at 11:47 p.m. and triggered a tsunami warning for parts of Java’s coastline that was lifted about two hours later.

Panicking people ran out of buildings in many areas and Indonesian television showed heavy traffic on roads as people fled coastal areas.

A 62-year-old man was confirmed dead in the Ciamis region of western Java and there were reports of more deaths and of injuries in the same region, said National Disaster Mitigation Agency spokesman Sutopo Purwo Nugroho.

He said buildings had collapsed and were damaged in several cities and towns of central and western Java.


Strong and shallow M6.5 earthquake hits Bouvet Island in South Atlantic Ocean – Third earthquake above M6.0 within 24 hours

Strange Sounds

A strong and shallow M6.5 earthquake hit Bouvet Island situated in the southern Atlantic Ocean on December 13, 2017 at a depth of 15.7 km (9.8 mi). In contrast, EMSC is reporting M6.5 BUT A DEPTH OF 300 km (186 miles). This is the third strong earthquake above M6.0 after two hit Iran within the last 24 hours (M6.1 and M6.2), during which at least 58 have been injured.

This third M6.0+ earthquake was preceded by a M6.2 earthquake that hit southeastern Iran at 08:43 UTC (12:13 local time) and a second – a M6.1 earthquake – that hit 12 hours later on December 12, 2017. Meanwhile numerous aftershocks are rattling the region. The M6.1 earthquake also injured at least 58 people.


North Korea’s nuclear tests have damaged Earth’s crust, caused tremors months later

NZ Herald – December 11, 2017

Two tremors detected in North Korea yesterday were likely to be aftershocks from the hermit nation’s reckless nuclear test in early September, a US Geological Survey official confirmed.

The mild 2.9 and 2.4 magnitude aftershocks were confirmed as “tectonic” in origin by the Vienna-based Comprehensive Nuclear-Test-Ban Treaty executive secretary Lassina Zerbo.

The USGS official claimed the tremors originated near the Punggye-ri nuclear test site – the location where North Korea carried out its largest nuclear test to date on September 3.

The official said: “They’re probably relaxation events from the sixth nuclear test. When you have a large nuclear test, it moves the Earth’s crust around the area, and it takes a while for it to fully subside.

“We’ve had a few of them since the sixth nuclear test.”


Siberian Super Volcano Erupts Spewing Scorching Hot Ash 6 Miles Into The Sky

Mac Slavo – December 7, 2017

A Siberian super-volcano is worrying scientists after it’s shocking and sudden eruption flung hot ash six miles into the sky. This volcano is one of the most active in Russia.

Scientists working at the geophysical department of the Russian Academy of Science in north-eastern Russia’s Kamchatka Krai region have confirmed the giant eruption took place at the site of the Shiveluch Volcano yesterday over a 20 minute period.  They also verified and saw the volcano spew piping hot ash 10 kilometers (6 miles) into the sky.  So far, no locals or villages have been affected by this volcano’s eruption, but it’s sparking fears that a larger and more powerful explosion could occur in the very near future.

This eruption comes just days after Mount Agung in Bali in Indonesia began erupting, causing thousands to flee.  The head of the volcano station, Yuri Demyanchuk, said the eruption was powerful.  “It was a powerful outburst, although it wasn’t accompanied by pyroclastic flows. There was much lightning in the ash column,” according to Demyanchuk.
