Popocatépetl volcano in Mexico registers 68 exhalations in 24 hours

volcano
Mexico's National Center for Disaster Prevention (Cenapred) reported that in the last 24 hours, the Popocatépetl volcano registered 68 exhalations accompanied by water vapor, gas and light amounts of ash, as well as four volcanotectonic earthquakes.

Cenapred reported that the Alert Traffic Light is in Phase 2 Yellow, which is why the Popocatépetl could continue with explosive activity of low to intermediate scale, mild to moderate ash rains in nearby populations are expected, as well as possible pyroclastic flows and short range mudflows.

The National Center for Disaster Prevention asked the population not to approach the volcano, and much less the crater, due to the danger involved in the fall of ballistic fragments and indicated that in case of heavy rains should move away from the bottoms of ravines by the danger of landslides and mudflows.

Thousands of people have been urged to evacuate after an increased eruption of Guatemala's 12,300ft 'Volcano of Fire'.

Dramatic pictures show glowing lava spewing from the summit of the volcano, located among the departments of Escuintla, Chimaltenango and Sacatepéquez in the south-central part of the country.

Disaster coordination authorities have asked ten communities to evacuate and go to safe areas.

This morning, David de Leon, spokesman for the National Coordinator for Disaster Reduction, said monitoring of the volcano's activity yesterday showed the intensity of the eruption was being maintained.

Campi Flegrei
An ancient Italian supervolcano that hasn't erupted in 500 years may be starting a stage of activity that could lead to a colossal eruption, spelling potential disaster for communities lying in its path.

Campi Flegrei may have entered a new magma cycle, according to newly released findings that suggest the feature's "subvolcanic plumbing system" is commencing "a new build-up phase." The researchers warn this could give rise "at some undetermined point in the future," to "a large volume eruption."

A large volcanic area west of Naples which has 24 volcanic craters, Campi Fieri, has "produced two cataclysmic caldera-forming eruptions and numerous smaller eruptive events over the past 60,000 years," according to the new paper. Calderas are vacant spaces left after rock explosions during eruptions.

Comment: Considering seismic and volcanic activity around the world is on the rise, the 'near future' may come sooner than the researchers think: For more on the dramatic changes happening on our planet, check out SOTT radio's: Behind the Headlines: Earth changes in an electric universe: Is climate change really man-made?

Bread-crust bubbles: Scientists discover new type of volcanic ash

LAVA BUBBLES Researchers have discovered a new kind of ash, dubbed bread-crust bubbles, which are tiny spheres of ash no more than a millimeter in diameter that form deep underground.
Bread-crust bubble
Bred krəst ˈbəb(ə)l n.

Tiny, gas-filled beads of volcanic ash with a scaly surface.
Scientists have identified a new type of volcanic ash that erupted from a volcano in central Oregon roughly 7 million years ago. The particles are similar to larger bread-crust bombs, which form as gases trapped inside globs of lava expand, cracking the bombs' tough exterior. Bread-crust bubbles, each no more than a millimeter wide, have a distinctly crackled surface that can reveal secrets about how volcanoes erupt, researchers reported November 4 at the Geological Society of America annual meeting in Indianapolis.

The researchers had been sifting through other types of volcanic ash in the lab when they spotted the strange ash formations. Viewing the bits of ash through a scanning electron microscope revealed their crusty texture, indicating the gas bubbles expanded rapidly on their way up to Earth's surface, but did not pop. Analysis of the texture also indicated the bubbles' depth when they first exploded in the foamy magma. In the case of the Oregon sample, says volcanologist Ben Andrews of the Smithsonian Institution in Washington D.C., the frothy ash formed roughly 500 to 2,000 meters deep - a short distance, geologically - and erupted from the volcano at a rate of about 30 to 80 meters per second.

Comment: Perhaps this will provide some insight into the different kinds of volcanic activity that has occurred on our planet, and what we can expect should we start seeing this kind of ash again.

Volcano Ebeko on Kuril Islands, Russia spews ash 2.8 miles

Volcano Ebeko
The volcano Ebeko on Paramushir Island, in Russia's Kuril Islands archipelago, spewed out a column of ash to a height of 4.5 kilometers (2.8 miles), the press service of the Russian Emergencies Ministry's department in the Far Eastern Sakhalin Region said in a statement on Sunday.
"On November 4, the emergencies control center of the Russian Emergencies Ministry's department in the Sakhalin Region received information that the Ebeko volcano was seen spewing ash to a height of up to 4.5 kilometers. The plume of ash has moved to the northeast of the volcano, to a distance of up to five kilometers," the statement read.

See another blockbuster confirmation of the Younger Dryas cosmic impact below. I keep a pretty close eye on our subject but had no idea such intricate, original and thorough work was underway in the Czech Republic. Gunther Kleteschka has appeared on several YDB papers, but has clearly been busy in his own laboratory collecting entirely new, informative and well dated expressions of the YDB boundary in lake sediments. His work and that of his local colleagues is clearly exciting and in keeping with the predictions made by the Younger Dryas Impact Hypothesis.

USGS: Yellowstone supervolcano threat level changed to 'high'

yellowstone volcano
The United States Geological Survey has increased the Yellowstone supervolcano threat to "high." This is the first time that the USGS has updated its volcano threat assessments list since 2006.

The USGS said that 11 of the 18 volcanoes they have classified as a "high threat" or a "very high threat" are located in Washington, Oregon, or California, "where explosive and often snow - and ice-covered edifices can project hazards long distances to densely populated and highly developed areas."

According to the Epoch Times, the danger list is topped by Kilauea in Hawaii, which has been erupting continuously in 2018. Mount St. Helens as well as Mount Rainier in Washington, Alaska's Redoubt Volcano, and California's Mount Shasta are also in the top five, according to what the USGS has said.

Lava from the Kilaeua volcano can be seen flowing into the Pacific Ocean near Kapoho Bay and Vactionland on the Big Island. Scientists said that the lava flow's impact on the local marine life could be felt for decades, if not a century
Hawaii's Kilauea volcano tops the list of 161 active or potentially active volcanoes assessed by the USGS.

The government agency looked at 24 hazard and exposure factors to assesses the volcanoes and update a volcanic threat assessment published by scientist John Ewert and colleagues 13 years ago.

The US has seen 120 eruptions and 52 episodes of notable volcanic unrest at 44 US volcanoes since 1980, the USGS said.

And of the 161 volcanoes, the assessment classed 18 as very high threat, 39 high threat, 49 moderate threat, 34 low threat, and 21 very low threat volcanoes.

Comment: As we enter solar minimum, Earth's rotation has slowed and a continuous increase in cosmic radiation has been recorded, in turn, there's been a rise in volcanic and seismic activity (amongst many other phenomena). And since we have yet to reach the lowest point of the solar cycle, we can only expect these events to become more frequent and extreme.
