Supernova theory explains global warming, extinction events, ice ages says engineer

Do Supernova Events Cause Extreme Climate Changes?
"Global warming will not be reduced by reducing man made CO2 emissions" - Dr. William Sokeland

In recent years, mass die-offs of large animals - like the sudden deaths of 211,000 endangered antelopes within a matter of weeks - have been described as "mysterious" and remain largely unexplained.

Determining the cause of the retreat to ice ages and the abrupt warmings that spawned the interglacial periods has remained controversial for many decades.

Dr. William Sokeland, a heat transfer expert and thermal engineer from the University of Florida, has published a paper in the Journal of Earth Science and Engineering that proposes rapid ice melt events and ice age terminations, extreme weather events leading to mass die-offs, and even modern global warming can be traced to (or at least correlate well with) supernova impact events.

The perspectives and conclusions of researchers who claim to have found strong correlations that could explain such wide-ranging geological phenomena as the causes of glacials/interglacials, modern temperatures, and mysterious large animal die-offs should at least be considered...while maintaining a healthy level of skepticism, of course.

Discovery - if that is potentially what is occurring here - is worth a look.

The star marks the epicenter of the earthquake detected Friday morning near Scottsboro.
What's believed to be the strongest earthquake to be detected in north Alabama this year occurred Friday morning near Scottsboro.

According to the U.S. Geological Survey, a magnitude 2.9 earthquake was detected about 10:38 a.m.

While that's a minor earthquake likely not to be noticed, it's the strongest one of the year so far. The previous strongest quake was magnitude 2.7 near Decatur.

It's also the fourth quake this year detected in northeast Alabama. Two were near Fort Payne in DeKalb County and another near Scottsboro in Jackson County.

It's at least the eighth earthquake in 2017 detected in the northern half of the state.

Friday's quake was detected nine miles northeast of Scottsboro and 24 miles north northwest of Fort Payne, according to the USGS. It occurred more than 5.6 miles below the earth's surface, the USGS said.

Shallow earthquake at 6.1 magnitude hits off the coast of Japan


Shaken: The 6.1 magnitude earthquake struck 424 miles off Japan's island of Kyushu
An earthquake of magnitude 6.1 struck off southern Japan on Thursday, the United States Geological Survey said.

The quake struck 424 miles off Japan's island of Kyushu at a depth of 6.2 miles, the agency said.

There are no immediate reports of damage or casualties.

This comes two weeks after a similar earthquake, at 6.3 on the Richter scale, hit 180 miles east of Iwaki, south of Fukushima, Japan.

It occurred 50 miles deep on the Japan trench, which is part of the area of seismic activity known as the Pacific Ring Of Fire.

A magnitude 6.4 earthquake has struck off the coast of Tonga
The large quake struck at 12am local time (12pm UK time) around 100km south east of the village of Pangai.

There were no immediate reports of damage from the quake on Wednesday.

The quake struck 206km east northeast of the Tonga capital and was a shallow 14 km deep, the US Geological Survey (USGS) said.

Tonga is located in the Ring of Fire, an earthquake danger zone where 80% of all tremors globally strike.

No immediate tsunami warning has been issued.

New fears Bali's Mount Agung could erupt at any moment as volcanic activity soars and magma rises to the surface


There are fresh fears that Bali's Mount Agung (pictured) could erupt after the volcano reached peak earthquake activity, with thousands of tremors a day
There are fresh fears that Bali's Mount Agung could erupt after the volcano reached peak earthquake activity today.

Up to 1,000 tremors have been recorded in the area each day, with the frequent movements indicating a flow of magma towards the surface, Perth Now reports.

It comes as Indonesia's Mount Sinabung erupted on Sunday, causing evacuations and spewing ash half a kilometre into the air.

The activity at Mount Agung is being closely monitored by airlines, with travel to Bali expected to be severely affected should an eruption occur.

An emergency operations centre has been set up at Bali's International Airport, with travel insurance companies also imposing restrictions on policies in the wake of the warnings.

La Palma volcano in the Canary Islands hit by hundreds of earthquakes in 15 hours


La Palma was hit by 44 earthquakes over a magnitude 2.1 from Friday evening
A shock map has been released by Spanish authorities showing where the tremors hit in the area surrounding the deadly Cumbre Vieja.

There were 44 earthquakes recorded up to 2.1 magnitude hit between Friday at 1.52pm and Saturday to 4.17am.

But experts believe the total number, including ones too small to be located, within the seismic storm was 352.

The quakes follow another seismic storm the weekend before. which saw around 50 tremors in three days, between 1.5 and 2.7 on the Richter Scale.

Yellowstone's supervolcano: Threat is greater than previously thought

Yellowstone supervolcano caldera
Scientists from the US Geological Survey who breezily informed the public that there's "nothing to worry about" with regards to the Yellowstone caldera, a supervolcano that should it erupt could cause potentially hundreds of thousands of deaths, should be eating their words.

Since about mid-July, the earth beneath the volcano has been shifting in a sign that magma could be rushing into the caldera's main chamber. Since then, there have been roughly 2,500 small-scale earthquakes recorded near the volcano, the largest stretch on record. Previous estimates had assumed that the process that led to the eruption took millenniums to occur.

The same estimates that USGS based their warning on.

As the New York Times explains, the Yellowstone caldera is a behemoth far more powerful than your average volcano. It has the ability to expel more than 1,000 cubic kilometers of rock and ash at once, 2,500 times more material than erupted from Mount St. Helens in 1980, which killed 57 people. That could blanket most of the United States in a thick layer of ash and even plunge the Earth into a volcanic winter.

As the Times points out, scientists expect a supervolcano eruption to scar the planet once every 100,000 years.

To reach their conclusion, the team of scientists spent weeks at Yellowstone's Lava Creek Tuff - a fossilized ash deposit from the volcano's last supereruption, where they gathered samples and analyzed the volcanic leftovers. The analysis allowed the scientists to pin down changes in the lava flow before the last eruption. The crystalline structures of the rocks recorded changes in temperature, pressure and water content beneath the volcano just like tree rings do.

USGS: 2.9-magnitude earthquake detected near North Korean nuclear test site

"We cannot conclusively confirm at this time the nature (natural or human-made) of the event," the USGS said


The US Geological Survey (USGS) detected a 2.9-magnitude earthquake in area close to North Korea's nuclear test site on Thursday evening, but is currently unable to explain the nature of the seismic event.

"This event occurred in the area of the previous North Korean Nuclear tests. The event has earthquake-like characteristics, however, we cannot conclusively confirm at this time the nature (natural or human-made) of the event," the USGS said in a brief statement.

The epicenter of the seismic event is located approximately 25 km away from Sungjibaegam, a town close to the Punggye-ri nuclear test site, at the depth of five kilometers.

The situation on the Korean Peninsula remains tense amid Pyongyang's active development of its missile and nuclear programs and the US-South Korean military drills. In July, North Korea carried out two tests of ballistic missiles, and on August 29 and September 15 it launched two missiles, which flew over Japan's territory. On September 3, Pyongyang announced a successful test of a hydrogen bomb.

Washington, Seoul and Tokyo believe that Pyongyang is preparing to perform another test of a ballistic missile or even a nuclear test soon.

Strong shallow 6.7 earthquake strikes near Bouvet Island in the South Atlantic

A strong earthquake with a preliminary magnitude of 6.7 has struck the Atlantic Ocean far south of Africa, centered near the Norwegian island of Bouvet, seismologists say. No tsunami alerts have been issued.

The earthquake, which struck at 6:43 p.m. local time (18:53 UTC) on Tuesday, was centered about 370 kilometers (230 miles) east of Bouvet Island, which is considered to be the most remote island in the world. It has no permanent population.

The U.S. Geological Survey (USGS) said Tuesday's earthquake had a preliminary magnitude of 6.7 and struck at a depth of 10 kilometers (6.2 miles), making it a shallow earthquake. The quake's epicenter is roughly halfway between South Africa and Antarctica.

40 earthquake tremors in 48 hours hit La Palma, Canary Islands


A scientific team will visit La Palma to keep track on the tremors
Fears of a volcano erupting on the Canary Islands has sparked panic as the Spanish archipelago was hit by more than 40 earthquake tremors in just 48 hours.

La Palma was rocked by more than 40 seismic movements of low magnitude and intensity between 1.5 and 2.7 on the Richter scale, according to the data of the National Geographic Institute.

The biggest earthquake, recorded at around 1pm on Saturday, had a magnitude of 2.7 and took place in the area of the Natural Park Cumbre Vieja, 28 kilometres deep.

The second largest quake, of 2.6, took place at 1.23pm on Sunday in the same area, while the third quake erupted at midnight on Monday, reaching a magnitude of 2.1, according to the Volcanological Institute of the Canary Islands (Involcan).

The earthquakes have sparked panic across the Canary Islands, with volcano experts pulled in to examine the unusual seismic activity.

María José Blanco, director of the National Geographic Institute in the Canary Islands, said the island has "never recorded a similar swarm" and although the energy levels are low and very deep, it is different from the seismic activity they have recorded so far.
