Anak Krakatau spewed hot ash during an eruption on Friday.
ANYER, Indonesia—The volcano that unleashed a tsunami and killed more than 400 people has collapsed to about a third of its previous height and is ejecting superheated magma into the sea, magnifying the power of the eruptions and sending ash more than a mile into the air.
The volcano, called Anak Krakatau, partially collapsed in a violent spasm on Dec. 22, causing a massive landslide that sent high waves barreling toward both shores of the Sunda Strait, the narrow passage between the islands of Java and Sumatra. The volcano’s cone is now about 360 feet above sea level, Indonesian officials said Saturday, reduced from more than 1,000 feet before the collapse.
Volcanoes erupt or collapse when a buildup of pressure inside becomes too much for the cone to sustain. Anak Krakatau has been erupting since June and scientists say it is impossible to tell what it will do next, but it could erupt violently or the stress on the rock could force another collapse and send a landslide into the strait, triggering another tsunami.

The earlier collapse pushed Anak Krakatau’s active vent underwater, creating a constant reaction with the sea that instantly turns water to steam. As it expands, the steam blows apart the molten rock.
“The big difference is unlike prior to the collapse, the erupting magma is being exposed directly to seawater, so the eruptions are more explosive and actually creating its own ‘volcano thunderstorm’ from all the steam, ash and volcanic gases,” said Erik Klemetti, a volcano expert at Denison University in Granville, Ohio. “It is inherently unstable as it’s just made of layers of lava and ash and debris.”
On Friday, it was sending ash more than a mile skyward in eruptions as frequently as every minute, officials said. Anak Krakatau has been barely visible from shore for the past week, partly due to storms. But even when the sky clears, the plume of ash generated by the underwater reaction, known as a pyroclastic cloud, smothers the silhouette. After dark, lightning strikes caused by energy released from the eruption can be seen every few seconds.
Perhaps most likely, scientists say, the volcano will erupt slowly and grow foot by foot, piling fresh lava on top of old. Over time, the cone will again push higher above the surface. Officials said Saturday the volcano’s smaller size makes the chance of another large collapse unlikely.

Yet our stupid politicians continue to believe the hype (ie Gorsian BS), and are concocting carbon tax laws that will eat at our national and personal wealth.

How about sunspot activities. If you plot a graph of sunspot activity and global temperatures, you'd see they mirror each other pretty closely. When they vary, is when there is an increase in vulcanism. The last deep solar minimum (little to no sunspot activity) started in the early 14th century and ended in the late 15th century. That time period is known as the Little Ice Age. From the late 15th century to the mid 20th century, sunspot activity gradually increased and low and behold, so did global temperatures. In the mid 20th century, sunspot activity surged and guess what? The term greenhouse effect was coined in an attempt to explain the cause of the global temperatures rise. During this period; the polar ice cap shrunk, glaciers receded, and oceans warmed. But so far we could still, if we stretch the point; blame it on the industrial revolution and the increase in greenhouse gases. But now, even though our country's CO2 emissions have dropped, worldwide CO2 emissions are higher than ever with China alone emitting more than the US and all of Europe combined. So what has the effect been on global temperatures? Are they rising? No! They peaked in 2009 and have been declining ever since. And low and behold, sunspot activity peaked in 2009 and has been declining at a rapid rate ever since until now they are nearly non existent. NASA says we are in a deep solar minimum. Solar minimums come and go usually lasting less between 3 to 6 months. This one has so far lasted 10 years. During this time global temperatures have been decreasing, the polar ice cap has been increasing with the ice sheet starting earlier each year, lasting later each year, and extending farther each year. The Pacific Ocean (the most monitored large body of water on the planet) has dropped more than a degree. That is a HUGE drop. NASA has a probe near the sun studying it, but cannot predict how long this solar minimum will last.
So whatever effect humans have on global climate; our sun trumps us by a long shot!!!!

Preaching to the choir here. I have tried to talk logic into the climate alarmists around me. Extremely difficult to get the message through. Thank God most don't vote. But unfortunately there are many who think Bill Nye is someone who has real knowledge. He's a snake oil salesman along with Gore.

At the least, perhaps Al Gore and his band of loonies can get an injunction against ALL Volcanoes to cease and desist.

Yes, it's doing what volcanoes do, but the carbon tonnage from one volcano doesn't come close to man's doing.

More ego filled delusional posts I see, well here are some facts for ya...When you realize that volcanism contributes 645 million tons of CO2 per year – and it becomes clearer if you write it as
0.645 billion tons of CO2 per year – compared to humanity's
29 billion tons per year, it's overwhelmingly clear what's caused the carbon dioxide increase in Earth's atmosphere since 1750.

But the carbon released by both human activity AND vulcanism; can make a drop in the bucket compared to what our sun does. Human activity has ZERO effect on sunspot activity!

So what? Carbon increase is still going up while global climate is cooling. And the warming trend started in the 15th century, not the 18th century. That CO2 has been increasing since 1750 instead of the late 1400s when the warming trend began, just emphasizes that it is NOT due to CO2. So the amount of carbon, whether from humans or not; is immaterial. {I tried to post the documentation from the NOAA, but their site is temporarily down.}
You got that right. Unfortunately, more and more people think it is important as a new poll reveals. I can't wait for the suit against the Government hits the Supreme Court. Maybe then the sides of the issue will have to bring out all their data and it gets sorted out in public... would take forever, but then this has been going on forever.

Are you kidding me, I cannot even debate such a stance, with that comment you don't even understand the issue, you have a nice day.
Trump closed the EPA site maybe he did it to NOAA also
