Fire Earth

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

Volcanic Activity Report:  5  – 11 August 2009

VoW: Kilauea

Kilauea
Since the vent collapse in late June, Kilauea’s summit plume had been wispy, translucent and low in SO2 content, resulting in improved air quality in Kona and Ka‘u. However, the summit vent has picked up in activity again this week. (Photo courtesy of Hawaiian Volcano Observatory). Source: Click Here.

VolcanoWatch Weekly [30 July 2009]

Posted by feww on July 30, 2009

Volcanic Activity Report: 22 July – 28 July 2009

VOW: Batu Tara

batu tara July 27 2009
Batu Tara remained active in late July 2009. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this photo-like image the volcano releasing a faint plume on July 27, 2009. The distinct segments of the plume suggest that the volcano has released ash and/or steam in pulses. The plume blows toward the northwest over the Flores Sea.  NASA image courtesy MODIS Rapid Response Team, Goddard Space Flight Center. Caption by Michon Scott.

Batu Tara remained active in mid-May 2009. On May 17, 2009, as the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this image, the tiny volcanic island released a plume of ash and/or steam. The volcano’s plume forms a counter-clockwise arc north of the volcano. East of that plume is another, fainter plume, almost certainly of the same origin, blowing westward over the Flores Sea.

Notes:

KVERT reported that during 17-18 and 20-24 July seismic activity from Shiveluch was above background levels. According to news sources, an ash plume rose to an altitude of 7 km (23,000 ft) a.s.l. late on 25 July. Increased seismicity, powerful ash bursts, and avalanches were also reported.

Based on information from JMA, the Tokyo VAAC reported that on 22 July explosions from Sakura-jima produced plumes that rose to altitudes of 1.8-2.4 km (6,000-8,000 ft) a.s.l. and drifted E and SE. On 23 July and 27 July pilots observed ash plumes. (Source: GVP)

Week 33 Volcano Watch

Posted by feww on August 21, 2008

13 August-19 August 2008

New Activity/Unrest:

Piton de la Fournaise. The massive Piton de la Fournaise on the island of Réunion is one of the world’s most active volcanoes. It is seen here in 1977 with a fresh black lava flow descending the outer NE flank of the shield volcano to the sea. An unvegetated summit lava shield (upper left) was constructed within an 8-km-wide caldera that is breached to the sea. Its sloping northern rim is marked by the diagonal vegetation line at the left. More than 150 eruptions have occurred since the 17th century, mostly from vents within the caldera. (Caption:Global Volcanism Program ).

Week 32 Volcano Watch

Posted by feww on August 13, 2008

6 August-12 August 2008

New Activity/Unrest:

Kasatochi Volcano is one of many mostly submarine volcanoes whose summit emerges from the waters of the Bering Sea off the southwest coast of Alaska. After earthquakes and other seismic activities starting on or around August 7, Kasatochi began erupting large plumes of ash and gases. On August 8, 2008, skies were cloudy when the MODIS on NASA’s Terra satellite passed overhead and captured this natural-color image. The bright clouds provided good contrast for the volcanic plume, which is dark brown.

The ash plume spread southeastward from the volcano over the Pacific Ocean. Weather patterns caused the plume to diffuse as it swirled counterclockwise. Beneath the plume, which is dark brown, a few breaks in the clouds reveal that the normally deep blue waters of the Pacific are turquoise-colored. This brightness may be the result of ash or rocks debris settling on the water’s surface. According to an article in an Anchorage newspaper, the ash cloud forced cancellation of scores of flights into and out of Alaska, stranding as many as 6,000 passengers. (Caption NASA)
