****** Climate altering VOLCANIC ERUPTIONS are now happening regularly. ******

Things are speeding up ....

This is what happened in the last twenty years of the 2000's.

Mount St Helen's 1980

Volcanic eruptions enhance the haze effect to a greater extent than the greenhouse effect, and thus they can lower mean global temperatures. It was thought for many years that the greatest volcanic contribution of the haze effect was from the suspended ash particles in the upper atmosphere that would block out solar radiation. However, these ideas changed in the 1982 after the eruption of the Mexican volcano, El Chichon. Although the 1980 eruption of Mt. St. Helens lowered global temperatures by 0.1OC, the much smaller eruption of El Chichon lowered global temperatures three to five times as much. Although the Mt. St. Helens blast emitted a greater amount of ash in the stratosphere, the El Chichon eruption emitted a much greater volume of sulfur-rich gases (40x more). It appears that the volume of pyroclastic debris emitted during a blast is not the best criteria to measure its effects on the atmosphere. The amount of sulfur-rich gases appears to be more important. Sulfur combines with water vapor in the stratosphere to form dense clouds of tiny sulfuric acid droplets. These droplets take several years to settle out and they are capable to decreasing the troposphere temperatures because they absorb solar radiation and scatter it back to space.

Mount Pinatubo in the Philippines 1991

The second-largest volcanic eruption of this century, occurred at Mount Pinatubo in the Philippines on June 15, 1991. The eruption produced high-speed avalanches of hot ash and gas, giant mudflows, and a cloud of volcanic ash hundreds of miles across.

On July 16, 1990, a magnitude 7.8 earthquake (comparable in size to the great 1906 San Francisco, California, earthquake) struck about 60 miles (100 kilometers) northeast of Mount Pinatubo on the island of Luzon in the Philippines, shaking and squeezing the Earth's crust beneath the volcano. At Mount Pinatubo, this major earthquake caused a landslide, some local earthquakes, and a short-lived increase in steam emissions from a preexisting geothermal area, but otherwise the volcano seemed to be continuing its 500-year-old slumber undisturbed.

In March and April 1991, however, molten rock (magma) rising toward the surface from more than 20 miles (32 kilometers) beneath Pinatubo triggered small earthquakes and caused powerful steam explosions that blasted three craters on the north flank of the volcano. Thousands of small earthquakes occurred beneath Pinatubo through April, May, and early June, and many thousand tons of noxious sulfur dioxide gas were also emitted by the volcano.

When even more highly gas charged magma reached Pinatubo's surface on June 15, the volcano exploded in a cataclysmic eruption that ejected more than 1 cubic mile (5 cubic kilometers) of material. The ash cloud from this climactic eruption rose 22 miles (35 kilometers) into the air. At lower altitudes, the ash was blown in all directions by the intense cyclonic winds of a coincidentally occurring typhoon, and winds at higher altitudes blew the ash southwestward.

Fine ash fell as far away as the Indian Ocean, and satellites tracked the ash cloud several times around the globe.

PINATUBO (1991) -- Mt. Pinatubo erupted in the Philippines on June 15, 1991, and one month later Mt. Hudson in southern Chile also erupted. The Pinatubo eruption produced the largest sulfur oxide cloud this century. The combined aerosol plume of Mt. Pinatubo and Mt. Hudson diffused around the globe in a matter of months. The data collected after these eruptions show that mean world temperatures decreased by about 1 degree Centigrade over the subsequent two years.

Latest Footage from Indonesia

You forgot the Aleutians, which are about to blow.

This is somber footage from "Russia Today"

OK, I haven't been following them religiously so there could be many I have missed.

What I notice is the media keeps trying to say oh that was big but just sky of the stratosphere which is what they said about the Russian volcanoes in October yes 33,000 feet high just sky of the stratosphere. They said the same about Ice lands earlier this year can you believe what they say?

You find the odd report that contractions what they say and does say into the stratosphere.

This below about Russians volcanoes in Oct says the ash was six miles high. Not sure what that equates to?

There is absolutely no question that this latest volcano is in the stratosphere. If 33,000 if just shy of the stratosphere, then this one is well into it at between 55.000 and 60,000 feet.

What's more this is a tropical eruption, the most dangerous to get into the stratosphere.

An eruption into the stratosphere near the poles does not do that much harm because the magnetic field pulls the ash to the poles and back down again.




Mount Merapi Volcano: "Worst eruption since 1872"

Mount Merapi continues to ravage central Indonesia with its strongest eruption since 1872.

The Darwin, Australia Volcanic Ash Advisory Center says the ash clouds has reached 55,000 to 60,000 feet, and drifted hundreds of miles downwind.
