Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Mayon Volcano Ejects Ash

Mayon Volcano: ‘undergoing an episode of increased activity’

Mayon Volcano Advisory – PHIVOLCS

August 10, 2008 – 12:00 P.M.

At 9:12 A.M. today, Mayon Volcano manifested mild ash explosion that reached an approximate height of 200 m above the summit crater before drifting east-northeast. The ash-ejection was recorded as explosion-type earthquake which lasted for one minute by the seismic network deployed around the volcano. Immediately after the explosion, visual observation becomes hampered by the thick clouds. During the past weeks, seismic activity had slightly increased and crater glow had slightly intensified. Precise leveling surveys conducted at Mayon from May 10 – 22, 2008 compared to February 17 – March 2, 2008 survey also showed inflation of the volcanic edifice.

Mayon Volcano overlooks a pastoral scene some five months before the volcano’s violent eruption in September 1984. Ruins from a nearby church destroyed in an 1814 eruption are visible in the foreground.

Pyroclastic flows at Mayon Volcano, Philippines, 1984. Pyroclastic flows descend the south-eastern flank of Mayon Volcano, Philippines. Maximum height of the eruption column was 15 km above sea level, and volcanic ash fell within about 50 km toward the west. There were no casualties from the 1984 eruption because more than 73,000 people evacuated the danger zones as recommended by scientists of the Philippine Institute of Volcanology and Seismology.

The above observations show that Mayon Volcano is undergoing an episode of increased activity probably related to magma movement and post eruptive behavior of the volcano. Although no major eruption is indicated, steam and ash explosions may occur in the following days.

In view of the above, PHIVOLCS reiterates that Mayon Volcano’s status remains at Alert Level 1. The public, however, is reminded that the 7-km Extended Danger Zone (EDZ) at the southeastern flank of the volcano and the 6-km radius Permanent Danger Zone (PDZ) at other areas remain off-limits due to the continuing threat from sudden small explosions and rockfalls from the upper slopes. Active river channels and those areas perennially identified as lahar-prone around the volcano should be avoided when there is heavy and prolonged rainfall. PHIVOLCS is keeping a tight watch over Mayon and shall immediately report any significant development to all concerned.

Alaska Airlines Defers to Volcanic Ash

Posted by feww on August 11, 2008

Where Alaska Airlines Daren’t Fly!

Alaska Airlines canceled dozens of flights starting Sunday evening as a towering plume of ash created by the eruption of a Kasatochi volcano last week made the flights hazardous. The cancellations affected flights from Alaska and Denver, Los Angeles, Portland, Seattle, San Francisco, and Vancouver, Canada.

Kasatochi is the third Aleutian volcano erupting since late July. Okmok began erupting July 12 and Mount Cleveland erupted July 21. (FEWW)

Kasatochi Volcano Latest Observations (AVO)
2008-08-10 23:23:14
Seismic activity detected on stations near Kasatochi continues to be low. This does not imply that seismic activity at the volcano has ceased, only that we detect very little activity at our existing stations, some 25 miles away. The helicorder plots on our web page appears to show increasing seismic activity over the past few hours, however much of this signal is background noise such as wind. The larger signals (e.g. 19:13 AKDT) are regional earthquakes not associated with the volcano.

A large drifting ash cloud from previous ash emissions on August 7 continue to be observed in satellite data. This ash cloud is drifting over the Gulf of Alaska and parts of SE Alaska, which is possibly the reason for a number of flight cancellations. (AVO)

2008-08-10 14:11:14 – Status Report
The intense seismic activity associated with the Kasatochi eruption has declined but low level activity can be detected on the AVO seismic network on nearby Great Sitkin Island (about 40 km (25 mi) to the east). Vigorous ash emissions (up to 35,000 feet) have not been observed in satellite data for over two days and AVO has received no pilot reports of ash clouds. (AVO)

Coast Guard press release:
The Alaska Volcano Observatory has reported Kasatochi Volcano has erupted just east of Adak Island, an island in the Aleutian Islands chain, causing an ash cloud in the area at an approximate elevation of 45,000 feet.

Due to possible sub-surface eruption , numerous large pumice rafts, volcanic gases, or ash fallout may cause hazards to navigation . All mariners are urged to stay outside of seven nautical miles of Kasatochi Island and to use extreme caution while transiting that area.

Any vessel coming in contact with ash or spotting floating debris is requested to contact the Alaska Volcano Observatory at (907) 786-7497. (USCG)

Stop Polluting Our Air!

Direct action protesters try to stop UK coal-fired power plant for a day

About a 1,000 climate protesters, who aimed to stop the output at Kingsnorth coal-fired power station for a day, demonstrated outside the plant in southeast England on Saturday.

Nearly 2,000 police and civilian security personnel surrounded the protesters. Police in riot gears brandishing batons charged at the protesters and arrested about 50 people.

“We just want to try and send a message to people that we don’t want any more new coal … it’s something that’s not going to help our future at all,” said Helen Atkinson, 26, a medical photographer from Cumbria, northwest England. (Source)

E.ON the German owned company that operates Kingsnorth is planning to construct two new “cleaner coal” units on the Kingsnorth site, which it claims will be 20 percent less polluting than conventional power stations. They would be the first coal-fired power stations to be built in Britain for 24 years. AFP reported.
