Ambrym Volcano Ash Plume
| Title |
Ambrym Volcano Ash Plume |
| Description |
In the South Pacific Ocean, the Ambyrm Volcano, originally captured in an image taken on April 27, continued to erupt in mid-May 2004. This image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite on May 15. Vanuatu Island is pictured at the top left of the image, and a plume of volcanic ash is drifting southeastward from Ambrym, which is near the Island?s center. MODIS detected a thermal signature (marked in yellow) in addition to the ash plume. The scene is available in other resolutions. Image courtesy Jeff Schmaltz, MODIS Rapid Response Team, NASA-GSFC |

Cyclone Ivy
| Title |
Cyclone Ivy |
| Description |
On February 25, Tropical Cyclone Ivy was continuing to gather strength and generate rough seas. In this image Ivy was located about 450 kilometers north of Port Vila, the capital of Vanuatu, and was moving west-southwest at six knots. The cyclone had maximum sustained winds of 75 knots and gusts to 90 knots and was intensifying. Image courtesy of Jesse Allen, NASA Earth Observatory at NASA Goddard Space Flight Center. |

Eruption on Lopevi, Vanuatu
| Title |
Eruption on Lopevi, Vanuatu |
| Description |
Vanuatu's Lopevi Volcano released a plume on May 3, 2007. The same day, the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite captured this image of the plume and its larger consequences. The U.S. Air Force Weather Agency reported an extensive area of vog resulting from the volcanic eruption. When gases from a volcano—particularly sulfur dioxide—react with oxygen, water, dust, and sunlight, volcanic smog (or vog) results. Besides Lopevi and its neighboring islands, this image shows the volcanic plume blowing westward away from the volcano. The plume appears as a small, mostly opaque puff of gray-beige. The resulting area of vog, which appears as a more transparent, dingy-gray haze, dwarfs the diminutive plume.Lopevi [ http://www.volcano.si.edu/world/volcano.cfm?vnum=0507-05= ] is a stratovolcano composed of alternating layers of solidified lava, hardened ash, and volcanic rocks. One of the island nation's most active volcanoes, this volcanic island is only about 7 kilometers (4 miles) wide. Eruptions have been recorded at Lopevi since the middle of the 19th century. You can download a 250-meter-resolution Lopevi KMZ file [ http://earthobservatory.nasa.gov/NaturalHazards/Archive/May2007/lopevi_amo_2007123.kmz ] for use with Google Earth.
