EARTH CORE ERUPTION
Tonga volcano spews spectacular plume into South Pacific sky
Mar 19, 2009 11:10 AM in
An undersea volcano in the South Pacific is spewing stunning columns of smoke, steam and ash thousands of feet into the air.
The eruption began Monday after a series
of earthquakes near Tonga, a 170-island archipelago between Australia and
Tahiti, residents told the Associated Press. There were magnitude-5.0 quakes
there Sunday night and Monday afternoon, according to the U.S. Geological
Though the Wellington Volcanic Ash Advisory Center (VAAC) issued an advisory for the area, the plume isn’t endangering* island residents and so far hasn’t hurt fish or other animals, according to the AP.
Yesterday a plume rose to between 15,000 and 25,000 feet (4.6 to 7.6 kilometers), the Smithsonian's Global Volcanism Program reported. "It's a very significant eruption, on quite a large scale," Tonga's chief geologist, Kelepi Maf, told the Times of London. This is not unusual for this area and we expect this to happen here at any time."
It’s unclear whether the earthquakes are linked to the eruption. Sally Kuhn Sennert, who writes the weekly volcano report for the Smithsonian, didn’t immediately return a call and email for comment.
But Simon Turner, a geochemist at Macquarie University in Sydney, told the Times that the quakes and volcano eruption probably aren’t linked. "If this eruption was caused by the earthquake, it would mean magma coming 110 kilometers (68 miles) to the surface in a few days," Turner told the newspaper. "I think that would be fairly unlikely."
Tonga is part of the ''ring of fire,” an arc of earthquake and volcanic zones in the Pacific. We’ve got more on what causes a volcano to erupt and the ring of fire.
Major earthquake off Tonga: US geological survey A major 7.9-magnitude earthquake struck off the Tonga islands region, seismologists said Friday, issuing a tsunami warning for Tonga, Samoa and Fiji. The quake, which hit at 6.17 am (1817 GMT), was centred 210 kilometres (130 miles) south-southeast of the Tongan capital Nuku'Alofa and 480 km east-southeast of Ndoi Island, Fiji. It struck at a depth of 10 km, the USGS said. A Tsunami warning was issued by the Pacific Tsunami Warning Centre for Tonga, Niue, Kermadec Islands, American Samoa, Samoa and Fiji. The centre said it did not yet know if a tsunami had been generated by the quake. "An earthquake of this size has the potential to generate a destructive tsunami that can strike coastlines in the region near the epicentre within minutes to hours. Authorities in the region should take appropriate action in response to this possibility," it said. There were no immediate reports of damage. The quake occurred near fault lines in the Pacific "Ring of Fire" where continental plates in the earth's crust meet and earthquakes and volcanic activity are common.
N.Z. Monitoring Tsunami Risk From Tonga Earthquake (Update1) March 20 (Bloomberg) -- New Zealand government officials are assessing the risks of a tsunami following an earthquake in the Tonga Islands region. The magnitude 7.9 temblor struck about 7:18 a.m. local time and was centered about 210 kilometers (130 miles) south-southeast of Tonga’s capital Nuku’alofa. Sea level readings confirm that a tsunami was generated, the Pacific Tsunami Warning Center said in an e-mailed statement. New Zealand has “convened the tsunami expert panel and all available New Zealand and international data about the earthquake and sea levels is being closely monitored and analyzed,” John Hamilton, director of the nation’s Civil Defence Ministry said in a statement.
SS: this was another earth core eruption .. the massive quake is the magma passing between the plates .. when the magma passes between the plates it picks up water which causes it to become very explosive .. it rushes up from the earth's core very quickly .. this same phenomena has been recorded in these archives on multiple instances .. the beached whales are in the same exact place as those that beached themselves before the GREAT INDONESIAN MEGAQUAKE ..
SS: the quakes magnitudes were once again played with by the USGS the next day to 7.6M .. this is their ways that have been recorded numerous times in these archives they play with the magnitudes after the fact .. i have learned in most cases the first magnitudes are the most best correct magnitudes and the later adjustments are them second guessing and watering them down .. so it is the policy of these secret order archives to go with initial magnitudes and write off most later adjustments as not as credible ..
SS: chaiten below was a 10,000 year old dormant caldera until last year, now it is active .
Volcano's sulfur dioxide pushing some farmers near Hawaii's Kilauea volcano out of business
March 9, 2009 - 5:37 AM
" Sulfur dioxide is not new on the
Big Island, where Kilauea has been erupting continuously since 1983. But last
March, the volcano began releasing two to four times more sulfur dioxide, and a
second, simultaneous eruption began at the summit's Halemaumau crater.
Sulfur dioxide volumes have reached levels unseen since scientists began keeping data in 1979. "

Some of the nearly 200 whales and several dolphins which have
beached themselves on King Island off southern Australia, seen here on March 2.
A total of 192 pilot whales and several dolphins got stranded on the island on
Sunday evening and around 140 had died while 14 had been refloated.
Chilean Volcano Erupts Three Times In 24 Hours
Published: February 26, 2009
Chaiten, Chile—Chile’s Chaiten volcano erupted again, on Tuesday, the third time in less than 24 hours.
The blast forced the remaining residents to flee their homes…
Vulcanologists are warning that this most recent explosion could push the lava flows in reach of the city.
It was devastated last May, when the volcano erupted for the first time in 9,000 years.
