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

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.

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.

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?

Mount Kusatsu-Shirane erupts
A Self-Defense Forces member died and a dozen other people were injured after a volcano erupted near a ski resort in Gunma Prefecture Tuesday morning, spewing cinders and possibly causing an avalanche.

Stones from the eruption of Mt. Kusatsu-Shirane hit a gondola lift and injured at least four people on board with shattered glass, according to local rescuers. The 9:59 a.m. eruption of the 2,171-meter mountain is the first since 1983, according to the Meteorological Agency.

The stones also crashed through the roof of a rest house where about 100 people had evacuated, the rescuers said.

Video footage from the top of the resort's gondola showed skiers gliding down the slopes as black rocks plummeted from the skies and snow billowed up as they struck the ground, sometimes just missing skiers. A cloud of black smoke later drifted in


Comment: Latest is 16 people were injured.
