A magma reservoir potentially hidden behind an underwater volcanic crater could have civilization-ending results if it ever erupts, according to Japanese scientists.

Experts from the Kobe University Ocean Bottom Exploration Center (KOBEC) have confirmed that a giant caldera or large crater exists in the Japanese Archipelago. The crater, measuring 32 cubic kilometers, is said to be the largest of its kind and the result of an explosive underwater eruption 7,300 years ago, according to their latest study.

Sitting between the Pacific and Philippine Sea Oceanic plates, Japan is a hotbed for seismic activity, which is why scientists are keen on updating methods of predicting natural disasters. The KOBEC team has been carrying out detailed surveys of the area and published their findings in Scientific Reports.

A process known as deformation, where subsurface rocks subtly change shapes, is occurring beneath the surface of Yellowstone which alerts experts.

Researchers state deformation occurs when there is a change in the amount of pressure in the magma chamber and experts are keeping an eye on the development.

Seismologists from UNAVCO, a nonprofit university-governed consortium, are using "Global Positioning System, borehole tiltmeters, and borehole strainmeters" to measure minute changes in deformation at Yellowstone.

Comment: All signs point to great changes occurring on our planet, to think that Yellowstone's behaviour is shifting along with it wouldn't be too much of a stretch of the imagination, and the data shows that it is: Also check out SOTT's monthly documentary: SOTT Earth Changes Summary - January 2018: Extreme Weather, Planetary Upheaval, Meteor Fireballs

Another large eruption registered at Turrialba volcano in Costa Rica

Turrialba Volcano Costa Rica

Turrialba Volcano Costa Rica
The Turrialba Volcano registered yet another important eruption, this Monday, February 12 at approximately 4:30 a.m. with a column that reached 1000 meters above the crater and 4,340 meters above sea level (14,235.2 ft.).

The impressive was even visible from the Irazu Volcano as you can see in the video included below. The emission of ash is continuous and of variable volume and has been constant for over one week now.

Ash is being dispersed by the winds to the Ash is being dispersed by the winds to the southwest and several communities have reported ashfall in the entire metropolitan area (Cartago, Alajuela, Heredia, San Jose).

Curious Hindustan villagers Richard Bissoon and Yoge Deochan visit the site of the mud volcano at the Devil's Woodyard, Hindustan New Grant which erupted on Monday night .
A few homes in a community in the south of Trinidad have been evacuated following at least two eruptions at the Devil's Wood Yard mud volcano this morning.

The rumbling began around 4 a.m. at the volcano in Hindustan Village near New Grant, Princes Town, and another eruption was reported after 9 a.m.

The Office of Disaster Preparedness and Management (ODPM) said it is closely monitoring the situation, along with the Environmental Management Agency (EMA), the Geological Society of Trinidad and Tobago, the University of the West Indies (UWI) Geological Society, the UWI Seismic Research Centre and the Princes Town Regional Corporation.

Police and fire officials also converged at the site.

Molten lava flows down the slopes of Mayon volcano during its mild eruption as seen from Legazpi city, Albay province, southeast of Manila, Philippines Tuesday, Jan. 30, 2018
A heavy shroud of ash from erupting Mount Mayon in the Philippines halted vehicles in at least two towns due to poor visibility as the volcano blew more lava and columns of ash from its crater, officials said Tuesday.

The Philippine Institute of Volcanology and Seismology said one large lava eruption lasted more than an hour and a half late Monday. Mayon belched an ash plume that reached 1.5 kilometers (one mile) above the crater and caused significant ash fall in the towns of Camalig and Guinobatan.

Authorities urged residents to seek treatment for skin irritation and other health issues and immediately clean their roofs and cars because of the corrosive effect of the volcanic ash, Office of Civil Defense regional director Claudio Yucot said.

Unexpected find by robots exploring undersea volcanic eruption

Back in 2012, the Pacific ocean experienced the biggest volcanic eruption that the planet had seen in a hundred years. An enormous plume of volcanic material bubbled up out of the water with fantastic force, in a dramatic show that, sadly, nobody managed to catch on camera.

Eager to find out exactly what had happened deep below the sea, scientists from the University of Tasmania in Australia have sent a pair of diving robots to examine the volcano (called Havre) and the surrounding area. The results are a lot of fun: according to volcanologist Rebecca Carey who led the study, "what we found on the seafloor was almost entirely different from what we expected".

Whenever a scientist says that something is the opposite of what they were expecting, you know things are interesting. Throw in a giant underwater volcano, and things get even better.

While the volcano's activity wasn't viewed from up close, thanks to its location at the bottom of the ocean, flotsam from the eruption was visible on satellite images that have been taken from space. From this, in 2015 (three years after the eruption), the scientists were able to pinpoint the location of the volcano, and were able to track how the area had surrounding changed from before things went boom.

The Mayon volcano has been emitting flaming lava and giant clouds of superheated ash
Millions of tonnes of ash and rocks from an erupting Philippine volcano could bury nearby communities due to heavy rain, authorities said Saturday, as tens of thousands flee over fears of a deadly explosion.

The official Philippine Institute of Volcanology and Seismology (Phivolcs) issued the warning as heavy rains lashed the area surrounding the Mayon volcano, which has been emitting flaming lava and giant clouds of superheated ash for about a week.

Rainwater could combine with the volcanic ash and rock to form deadly, fast-moving mudflows -- called "lahars" -- that could sweep away entire settlements, authorities said.

A huge column of ash shoots up to the sky during the eruption of Mayon volcano Monday, Jan. 22, 2018 as seen from Legazpi city, Albay province
The Philippines' most active volcano ejected a huge column of lava fragments, ash and smoke in a thunderous explosion Monday, sending thousands of villagers back to evacuation centers and prompting a warning that a violent eruption may be imminent.

The midday explosion sent superheated lava, molten rocks and steam between 3.5 to 5 kilometers (2 to 3 miles) into the blue sky, and then some cascaded down Mount Mayon's slopes and shrouded nearby villages in darkness, Renato Solidum of the Philippine Institute of Seismology and Volcanology and other officials said.

From the crater, the deadly debris billowed about three kilometers (1.8 miles) down on the southern plank of Mayon toward a no-entry danger zone. There were no immediate reports of deaths or injuries, officials said.


Comment: UPDATE (25.01.18)

Mayon volcano, which has been erupting for almost two weeks in the Philippines, still appears to be swelling with magma under the surface, scientists said earlier today. More than 74,000 people are staying in dozens of emergency shelters as the volcano continues to belch lava, ash and superheated gas and rocks. Officials are worried the eruption may last months, affecting the education, health and livelihoods of people in its shadow.

The Philippine Institute of Volcanology and Seismology said tremors, pyroclastic flows and emissions of sulfur dioxide were detected Wednesday and early Thursday. Lava erupting up to 500 meters (1,640 feet) high was spilling down the slope, with one lava flow extending 3 kilometers (1.8 miles) from the crater. Ash plumes still rising up to 5 kilometers (3 miles) high have spread ash onto farms and towns nearby, darkening the skies and forcing villagers to wear masks.

The institute said GPS and other measurements indicated a sustained swelling or inflation of the mountain surface, which was consistent with magma rising and creating pressure. The alert level for Mayon remains four on a scale of five, indicating a violent eruption may be imminent.

String of earthquakes and volcanic eruptions hits Ring of Fire - at least five events in two days

Volcanic eruptions in Japan, the Philippines and Bali. Massive earthquakes in Alaska and Indonesia.


The rash of natural disasters over the past two days have one common denominator: they all occurred along the so-called Ring of Fire, a sprawling horseshoe-shape geological disaster zone.


Comment: A geologist from the US Geological Survey says these events are not connected - yet they all took place in rapid succession in the Ring of Fire, which is constantly active. So what he actually means is that he doesn't know if they are directly connected - although evidently they are connected by the Ring of Fire itself.

While we appreciate that he is trying to be cautious with his words, he should at least acknowledge the obvious: That the events are at least indirectly connected, and that it is possible - even likely - that there is also a direct connection given that they all happened within two days. And if so, what could that mean?
