Volcanic eruptions

New explosion of ash at Costa Rica’s Turrialba Volcano

L. Arias

Costa Rica’s Turrialba Volcano, located 50 kilometers east of San José, erupted at 1:12 p.m. on Monday and launched ash and vapor into the air for about 10 minutes, experts with the University of Costa Rica (UCR) and the National University (UNA) reported.

This is the second event this month after another 10-minute explosion recorded on Dec. 7. also spewed ash and gases into the air.

Experts from UNA’s Volcanological and Seismological Observatory of Costa Rica (OVSICORI) reported the explosion reached just under 400 meters in height.

UCR’s Mauricio Mora at 2:30 reported there were no more explosions. Mora was conducting an inspection in the volcano’s surrounding areas and said experts are evaluating whether the explosion was an isolated event or is part of an eruptive process.

Volcano Eruption in Japan on December 07 2015 08:00 AM (UTC).

Mount Aso in southwestern Japan’s Kumamoto prefecture had a small-scale eruption Monday morning, its first since Oct 23, the weather agency said. The eruption spewed smoke about 700 metres above the No. 1 crater of Mt Nakadake, one of the five peaks that constitute Mt Aso, the Japan Meteorological Agency said. There have been no reports of people injured so far. The agency maintained its volcanic alert level at 2 on the scale of 5, warning people not to approach the crater. Rocks could fall within one kilometre of the crater, it said. “An eruption of this level can happen at any time,” an official of the agency’s Fukuoka Regional Headquarters said. The alert level for Mt Aso was raised to 3 following its eruption on Sept 14, which warned against approaching the mountain, but it was lowered by one notch on Nov 24 amid diminished volcanic activity.

New Island Grows Twelve Times Bigger Since Popping Up Two Years Ago

I cover science and innovation and products and policies they create.

A NASA image from 2014

It’s not exactly a Pacific beach resort just yet, but the Japanese Coast Guard reports that a volcanic island that first popped up in the middle of the ocean two years ago has already grown to twelve times its initial size.

Molten rock cooled by the ocean first poked out of the water in November, 2013, when it was initially spotted next to island Nishinoshima, which it eventually grew to engulf.

A New Volcanic Island Swallows Its Older Sister

 

Tens of thousands of years ago, an undersea volcano a thousand kilometers south of Tokyo reached a milestone: Its peak reached the surface of the Pacific Ocean. It became an actual island. For millennia it slept, but in the 1970s a series of eruptions grew the island, which was named Nishinoshima. It was tiny, just a couple of hundred meters across.

But then there were a series of eruptions just south of the island in November 2013, in a still-submerged part of the volcano. This created a second peak, which poked through the water’s surface to become a new island just a few hundred meters from Nishinoshima.

That wouldn’t last: The new island grew as the volcano continued to erupt, and just before New Year’s Day 2014, the new island grew so big it actually connected to the old island. Now there is just one … and it’s still erupting, as you can see in this lovely image taken by the Landsat 8 satellite on March 20, 2014:

MEDAN – Mount Sinabung in Karo regency, North Sumatra, erupted forcefully once again on Wednesday and may threaten the opening of the Lake Toba Festival by Tourism Minister Arief Yahya in Berastagi, also in Karo, slated for Thursday.

No casualties were reported following the eruption, but pyroclastic flows drifting to the southeast affected a number of villages that have long been abandoned by residents.

“The current wind direction is directed to the southwest, but if it blows to the east the Lake Toba Festival will be disrupted as the spread of ash would reach Berastagi,” Mt. Sinabung Observation Station staff member Deri Hidayat told The Jakarta Post.

Deri said the volcano discharged the clouds at 1:47 a.m. and 9:28 a.m.

He added the pyroclastic clouds, which drifted as far as 3.5 kilometers, affected Bekerah and Simacem villages.

He said both villages had long been left empty as they were inside a designated danger zone.

Deri added that Mt. Sinabung had also emitted volcanic ash to a height of 2,000 meters toward the southwest. He said the spread of ash could disrupt the Lake Toba Festival if the wind changed direction in coming days.

Residents from communities near Ecuador’s Tungurahua volcano faced a massive cleaning operation on Thursday (19 November) after the volcano erupted, covering houses and fields with smoke and ash. Authorities issued an orange alert as emissions reached 2,500 metres above the crater.

In nearby Queros, one of the most affected communities, officials registered 10kg of ash per square metre.

As he swept the street near his house, resident Luis Vaca said the volcanic material was damaging crops. “Ash is falling everywhere; it’s strong, especially in the countryside where it’s falling more heavily. It’s damaging the crops. It would be good if the president came to visit us,” he said.

The Economic Collapse

Are You Prepared For The Coming Economic Collapse And The Next Great Depression?

The Ring Of Fire - Photo from Wikipedia

Have you noticed that seismic activity along the Ring of Fire appears to be dramatically increasing?  According to Volcano Discovery, 39 volcanoes around the world have recently erupted, and 32 of them are associated with the Ring of Fire.  This includes Mt. Popocatepetl which sits only about 50 miles away from Mexico City’s 18 million inhabitants.  If you are not familiar with the Ring of Fire, it is an area roughly shaped like a horseshoe that runs along the outer perimeter of the Pacific Ocean.  Approximately 90 percent of all earthquakes and approximately 75 percent of all volcanic eruptions occur along the Ring of Fire.  Just within the last 24 hours, we have witnessed a 4.4, a 5.4 and a 5.7 earthquake in Alaska, a 6.8 earthquake in Chile and 20 earthquakes in Indonesia of at least magnitude 4.3.  And as you will see below, this violent shaking along the Ring of Fire seems to continue a progression of major disasters that began back during the month of September.

 

For whatever reason, our planet suddenly seems to be waking up.  Unfortunately, the west coast of the United States is one of the areas where this is being felt the most.  The little city of San Ramon, California is about 45 miles east of San Francisco, and over the past several weeks it has experienced a record-breaking 583 earthquakes

 

A total of 583 small earthquakes have shaken San Ramon, California, in the last three weeks or so – more than five times the record set 12 years ago, according to the latest US Geological Survey updates.

 

“It’s the swarm with the largest number of total earthquakes in San Ramon,” said USGS scientist David Schwartz, who is more concerned about the size of quakes than he is the total number of them. Still, the number tops the previous record set in 2003, when 120 earthquakes hit over 31 days, with the largest clocking in at a magnitude of 4.2.

 

Could this be a prelude to a major seismic event in California?

 

We shall see what happens.

 

Meanwhile, records are being shattered in the middle part of the country as well.

 

For instance, the state of Oklahoma has already set a brand new yearly record for earthquakes

 

The state recorded its 587th earthquake of 3.0 magnitude or higher early this week, breaking the previous record of 585. That record was set for all of 2014, meaning that Oklahoma has now had more 3.0 magnitude or higher earthquakes so far in 2015 than it did in all of 2014. So far this year, E&E News reports, Oklahoma’s averaged 2.5 quakes each day, a rate that, if it continues, means the state could see more than 912 earthquakes by the end of this year.

 

Oklahoma has also experienced 21 4.0 magnitude or greater earthquakes so far this year — an increase over last year, which saw 14.

 

And just over this past weekend there was a very disturbing series of earthquakes in the state

 

Starting with a magnitude-4.1 temblor at 5:11 a.m. close to the Oklahoma-Kansas border, the region experienced a series of six earthquakes within a 75-minute period Saturday morning, the U.S. Geological Survey reported on its website.

 

The largest earthquake Saturday morning was the 4.1, which had an epicenter nine miles northwest of Medford, Okla., 59 miles southwest of Wichita.

 

That was followed by five more quakes near Medford with magnitudes of 2.5, 2.8, 2.5, 3.1 and 2.9 – the last of which came at 6:24 a.m.

 

A seventh earthquake – this one a magnitude-4.2 temblor – was recorded at 12:29 p.m., 10 miles north-northwest of Medford.

 

So why aren’t more Americans alarmed that these records are being broken?

Eaten away by ‘vog’: Acid fog eroding rocks on Mars

Scientists believe they have figured out why rocks on Mars are eroding. They say an acidic fog created by volcanic eruptions on the red planet is the probable culprit.

Planetary scientist Shoshanna Cole came up with the theory after studying a 100-acre area on Husband Hill in the Columbia Hills of the Gusev Crater on Mars using data gathered by a number of instruments on the 2003 Mars Exploration Rover Spirit.

She found that acidic vapors released by eruptions may have been responsible for eating away rocks on the Watchtower Class outcrops on the Cumberland Ridge and Husband Hill summit.

“The special thing about Watchtower Class is that it’s very widespread and we see it in different locations. As far as we can tell, it is part of the ground there,” which means that these rocks record environments that existed on Mars billions of years ago, Cole said in a press release submitted by the Geological Society of America.

End Of The American Dream

The American Dream Is Becoming A Nightmare And Life As We Know It Is About To Change

Popocatepetl - from Wikipedia

 

More than 25 million people live in the vicinity of North America’s 2nd-highest volcano, and in recent weeks this volcano has been steadily rumbling and has been spewing out massive amounts of black smoke and ash.  I have previously written about “the most dangerous mountain in the United States” (Mt. Rainier), but if the volcano that I am talking about today experiences a full-blown explosive eruption it could potentially be a cataclysmic event beyond what most of us would dare to imagine.  Popocatepetl is an Aztec word that means “smoking mountain”, and it is also the name of a giant volcano that sits approximately 50 miles away from Mexico City’s 18 million residents.  “Popo”, as it is called by locals, was dormant for much of the 20th century, but it came back to life in 1994.  And now all of this unusual activity in recent weeks has many wondering if a major eruption may be imminent.

Historians tell us that Popocatepetl had a dramatic impact on the ancient Aztecs.  Giant mud flows produced by massive eruptions covered entire Aztec cities.  In fact, some of these mud flows were so large that they buried entire pyramids in super-heated mud.

But we haven’t witnessed anything like that in any of our lifetimes, so it is hard to even imagine devastation of that magnitude.

In addition to Mexico City’s mammoth population, there are millions of others that live in the surrounding region.  Overall, there are about 25 million people that live in the immediate vicinity of Popocatepetl.  Thankfully, we haven’t seen a major eruption of the volcano in modern times, but at some point that will change.

As most of you already know, Mexico sits on the “Ring of Fire” that stretches along the outer rim of the Pacific Ocean.  Over the past couple of years seismic activity throughout this area has started to really heat up, and according to Volcano Discovery there are dozens of volcanoes associated with the Ring of Fire that have recently erupted.
