Volcanic Emissions: Hawaii County Declared Disaster Area

Hawaii County declared agricultural disaster area amid continuing volcanic emissions

The U.S. Department of Agriculture (USDA) has declared Hawaii County in Hawaii as a primary natural disaster area due to losses caused by volcanic emissions that began on January 1, 2011, and continue.

Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Activity Summary for past 24 hours: Overall eruptive activity was low. DI deflation and dropping of the summit lava lake started this morning. Within Pu`u `O`o Crater, glow was visible from sources on the northeast and southeast edges of the floor.  Surface flows southeast of Pu`u `O`o remained active but there were no active surface flows on the pali, coastal plain, or entering the ocean. Seismic tremor levels were low and gas emissions were elevated. (Source: HVO)

This photograph shows the east rim of Pu`u `Ō `ō crater. A collapsed spatter cone revealed a swiftly flowing stream of lava heading northeast, into the tube system that supplies the active flow field. The active flows today were 6 km (3.7 miles) southeast of Pu`u `Ō `ō. Dated 8 February 2012.  (Source: HVO)

Episodes 1–48b (1983–1986) are shown in dark gray; Episodes 48c–49 (1986–1992) are pale yellow; Episodes 50–53 and 55 (1992–2007) are tan; Episode 54 (1997) is yellow; Episode 58 (2007–2011) is pale orange; the episode 59 Kamoamoa eruption (March 2011) is at left in light reddish orange; and the episode 60 Pu‘u ‘Ō‘ō overflows and flank breakout (Mar–August 2011) is orange. The currently active flow (episode 61) is shown as the two shades of red—pink is the extent of the flow from September 21, 2011, to January 26, 2012, and bright red marks flow expansion from January 26 to February 8. The active lava tube is delineated by the yellow line within the active flow field. The contour interval on Pu‘u ‘Ō‘ō is 5 m.  (Source: HVO)

VOW:  Ambrym

Destructive acid rain caused by eruption

According to press reports, an eruption from Benbow Crater occurred on 10 February [1979.]  Gases from the eruption caused acid rainfall on the SW portion of Ambrym Island, destroying most vegetation within 24 hours, contaminating water supplies, and burning some inhabitants. Jean-Luc Saos, Director of Mineral Resources for the New Hebrides government, reported a high concentration of HCl and sulfur compounds in the volcanic gases. Although heavy ashfalls have occurred in the area in the past, this is the first report of acid rains. More …

A hazy layer of vog—volcanic fog—overlies Malekula and a few other islands of the Vanuatu archipelago in this natural-color satellite image. The source of the vog is Ambrym, a volcano in the southeast (lower right) corner of this scene. The haze extends over the Coral Sea several hundred kilometers to the northwest. Ambrym emits sulfur dioxide—the gas responsible for the formation of vog— intermittently. (Kilauea Volcano has recently affected the residents of Hawaii with similar vog emissions.)  The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite acquired this natural-color image on October 6, 2009.

Ambrym, a large basaltic volcano with a 12-km-wide caldera, is one of the most active volcanoes of the New Hebrides arc. A thick, almost exclusively pyroclastic sequence, initially dacitic, then basaltic, overlies lava flows of a pre-caldera shield volcano. The caldera was formed during a major plinian eruption with dacitic pyroclastic flows about 1900 years ago. Post-caldera eruptions, primarily from Marum and Benbow cones, have partially filled the caldera floor and produced lava flows that ponded on the caldera floor or overflowed through gaps in the caldera rim. Post-caldera eruptions have also formed a series of scoria cones and maars along a fissure system oriented ENE-WSW. Eruptions have apparently occurred almost yearly during historical time from cones within the caldera or from flank vents. However, from 1850 to 1950, reporting was mostly limited to extra-caldera eruptions that would have affected local populations. Caption: GVP

News From GVP:

On 29 September, people living in Chaitén town, 10 km SW of Chaitén’s Domo Nuevo 1 (Phase I) and Domo Nuevo 2 (Phase II) lava-dome complex, noticed that the eruption column was larger. Scientists conducted an overflight and saw a third lava dome (Phase III) in the SW area of the complex, which had filled up a depression left by a collapse on 19 February.

According to news articles from 2 October, increased seismicity at Gaua was detected during the previous two weeks. Villagers living nearby reported ashfall and sulfur odors.

An explosive eruption from Galeras on 30 September prompted INGEOMINAS to raise the Alert Level. An ash plume rose to an approximate altitude of 12.3 km (40,400 ft) a.s.l. and drifted E, then N. —GVP

The Floating Toxic Garbage Island

WILD FACTS SERIES: North Pacific Gyre

A patch of garbage dubbed the Great Pacific Garbage Patch floats in the middle of the Pacific Ocean in North Pacific Gyre. Depending on the source, the size estimate of the patch varies from the size of Texas to twice as large as the continental United States.

• About 46,000 pieces of plastic float on each square mile of sea (Source: telegraph.co.uk)
• Researcher Dr Marcus Eriksen believes the Great Pacific Garbage Patch stretches from about 500 nautical miles off the coast of California, across the Northern Pacific to near the coast of Japan.
• According to the Independent newspaper 100 million tons of plastic garbage float in the North Pacific Gyre.
