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 ).

New Activity/Unrest:
Plume from Kasatochi Volcano, Aleutian Islands

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)

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)
ORANGE/WATCH
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)

Recent activity at the Kilauea volcano has increased atmospheric levels of sulfur dioxide in the districts of Kau and Puna, Hawaii, resulting in a spike of sulfur of 9 parts per million, which is considered to be extremely high. (Source)

The skeletal remains of a young woman killed by the eruption of Mount Vesuvius in A.D. 79. The skeleton, unearthed from the ruins of Herculaneum in 1982, was named the “Ring Lady” because of the emerald and ruby rings found on the woman’s left hand. Two gold bracelets and gold earrings were also found by the woman’s side. (Source: Wikipedia)

Okmok Activity – Color Code RED : Alert Level WARNING
Okmok Volcano Activity Notifications
by AVO
The eruption of Okmok Volcano continued throughout this week with persistent ash emissions rising from 15,000 to 25,000 feet. From July 19 to July 20 the color code was increased to red in response to a more vigorous eruptive episode which produced ash to 30,000 feet. Photographs and an overflight by Alaska Volcano Observatory staff on July 20 and 21 confirmed the existence of multiple vigorous vents on the caldera floor.

Seismicity was characterized by intermittent bursts of volcanic tremor early in the week. This changed to continuous mid-level volcanic tremor on July 23, which persists to the current time. Amplitude of tremor has been generally constant since July 21.
Although there has been little change in the eruption in the past several days, stronger explosive activity could resume at any time with little or no warning.

Cleveland Volcano Activity Notifications
2008-07-25 12:18:38 – Weekly Update by AVO
Based on reports from fishing boats Cleveland Volcano began erupting at approximately 12:00 AKDT (20:00 UTC) on July 21, 2008. This eruptive episode is more intense than that observed over the past several years. Pilot reports and satellite data have documented a persistent low level ash emission from 10,000 to 20,000 feet throughout the week when the volcano was visible through clouds. A large thermal anomaly suggests the presence of an ongoing active lava flow.
