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!

[Top] Activity at the west Waikupanaha ocean entry, where lava reached the ocean this past weekend, continues. The entry spans about 200 yards, with many small lava streams entering the water. [Above] On the east margin of the entry, lobes were advancing over a small black sand beach.  USGS/ HVO [Dated 4 Nov 2009] Click image to enlarge.

HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE
Thursday, November 5, 2009 7:48 AM HST (Thursday, November 5, 2009 17:48 UTC)

KILAUEA VOLCANO (CAVW #1302-01-)
19°25’16” N 155°17’13” W, Summit Elevation 4091 ft (1247 m)
Current Aviation Color Code: ORANGE
Aviation Color Code: ORANGE

Activity Summary for past 24 hours:
Growth and partial collapses of the Halema`uma`u Overlook vent cavity floor continued periodically obscuring and revealing the circulating lava pond surface. Sulfur dioxide emission rates from the Halema`uma`u and east rift zone vents remain elevated. Lava flows are active on the coastal plain. Lava is also flowing through tubes to the coast and entering the ocean at two locations west of Kalapana.

Past 24 hours at Kilauea summit:
The Overlook vent webcam images again showed fluctuating glow and spattering from a single elongated hole deep within the Halema`uma`u vent cavity; the rim of this hole was built progressively inward by spatter making the hole smaller until two more partial collapses occurred early this morning again revealing the circulating and spattering lava pond below. Glow from the vent was visible from Jaggar Museum overnight. This morning, a near white plume is moving southwestward and low over the Ka`u Desert. The most recent sulfur dioxide emission rate measurement was 500 tonnes/day on November 3, which is elevated above the 2003-2007 average of 140 tonnes/day. Small amounts of ash-sized tephra continued to be dropped from the plume near the vent.

Past 24 hours at the middle east rift zone vents and flow field: Magma continued to degas through Pu`u `O`o crater before erupting from the TEB vent, located 2 km to the east. The most recent sulfur dioxide emission rate measurement was 1,400 tonnes/day on November 4, which is close to the 2003-2007 average of 1,700 tonnes/day More …

Kilauea Spews More Lava

kilauea_ali_2009306
The rift zone on the eastern slopes of Hawaii’s Kilauea Volcano has been erupting since January 1983, the longest eruption in recorded history. Pu‘u ‘O‘o and the Thanksgiving Eve Breakout vent—two centers of volcanic activity—emit steam and other gases in this natural-color satellite image. Lava currently reaches the surface at the Thanksgiving Eve Breakout vent and flows southeast (towards the lower right) through a lave tube to the ocean. Small plumes of gas reveal the path of the lava. In general, the youngest lava flows are black, and older, weathered, flows are gray or brown. Surviving vegetation is bright green.

SI / USGS Weekly Volcanic Activity Report
(28October – 3 November 2009)

New activity/Unrest:

Ebeko, Paramushir Island | Galeras, Colombia | Karangetang [Api Siau], Siau I | Manam, Northeast of New Guinea (SW Pacific) | Nevado del Huila, Colombia | Soufrière Hills, Montserrat

GVP Volcano News:

INGEOMINAS reported that on 28 October a pulse of tremor from Nevado del Huila was followed by an ash plume that rose to an altitude of 8.3 km (27,200 ft) a.s.l. On 3 November, residents of Mosoco (20 km SSW) saw collapses from the W side of the dome generate small pyroclastic flows and incandescence at night.

MVO reported that during 23-30 October seismic activity from the Soufrière Hills lava dome was at a slightly lower level that the previous week. Numerous pyroclastic flows occurred in most of the major drainage valleys and rockfalls were concentrated in the S. On 29 October, a 40-m-high spine was seen protruding from the summit. —GVP

Ongoing Activity:

Barren Island, Andaman Is | Chaitén, Southern Chile | Dukono, Halmahera | Karymsky, Eastern Kamchatka | Kilauea, Hawaii (USA) | Kliuchevskoi, Central Kamchatka (Russia) | Krakatau, Indonesia | Popocatépetl, México | Rabaul, New Britain | Sakura-jima, Kyushu | Shiveluch, Central Kamchatka (Russia) | Suwanose-jima, Ryukyu Islands (Japan)

Volcano Watch No. 47

Posted by feww on November 27, 2008

19 November-25 November 2008

New Activity/Unrest:

Featured Volcano: Dukono

Country: Indonesia
Region: Halmahera
Volcano Type: Complex volcano
Summit Elevation: 1,335 m
Latitude:        1.68°N         1°41’0″N
Longitude: 127.88°E          127°53’0″E

One of Indonesia’s most active volcanoes, Dukono is located at the northern end of Halmahera Island. Dukono has a broad profile and is capped by many compound craters. Dukono has displayed more or less continuous explosive activity since 1933, occasionally accompanied by lava flows. Photo by Vivianne Clavel, June 1991. 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 ).

Ongoing Activity:

The Weekly Volcanic Activity Report is a cooperative project between the Smithsonian’s Global Volcanism Program and the US Geological Survey’s Volcano Hazards Program. This page is updated on Wednesdays, please see the GVP Home Page for news of the latest significant activity.

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)
