Continued Eruption of Manam Volcano |
| Description |
The vast expanse of the Pacific Ocean floats over the Earth's molten core on a section of the Earth's crust called the Pacific Plate. Along its edges, the plate crashes against the plates holding the continents with often violent force. In most places, the cold Pacific plate is pulled under the continental plates, where it crumbles into hot magma, a process called subduction. Along the edges of the plates, the clashing and breaking crust generates powerful earthquakes, and the shallow molten rock fuels volcanoes. The result is the "Pacific Ring of Fire," a circle of high volcanic and seismic activity along the rim of the Pacific Ocean. Papua New Guinea's Manam Volcano sits in the southwest segment of the Pacific Ring of Fire where the Pacific Plate sinks beneath the Indo-Australian Plate. One of the region's most active volcanoes, Manam forms a tiny 10-kilometer wide island that rises from the Bismarck Sea 13 kilometers off the shore of Papua New Guinea. The volcano has erupted frequently since its first recorded eruption in 1616, and was erupting on November 15, 2004, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) flew overhead on NASA's Terra [ http://terra.nasa.gov/ ] satellite. In this true-color image, dark ash rises from the volcano and is drifting southwest over Papua New Guinea. The current eruption began on October 24 with an explosive eruption that forced thousands of villages on Manam Island out of their homes. According to news reports, the ongoing eruption has not caused any injuries. NASA image courtesy Jacques Descloitres, MODIS Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov ] at NASA GSFC |

Earthquake Raises Reefs in the Solomon Islands |
| Description |
When people talk about change happening on a geologic time scale, most of the time, they mean that the change happens over the course of millions of years: the Colorado River gradually cuts through the soft rock of the Colorado Plateau until it has made a 4,000-foot-deep chasm, the Grand Canyon, continents drift centimeters at a time, slowly changing the shape and position of landmasses on the Earth. Most of the time, change is slow, but sometimes, geologic change happens all at once. This was the case on Ranongga Island in the Solomon Islands. In the early morning hours of April 2, 2007, a magnitude 8.1 earthquake shook the Solomon Islands, its epicenter southwest of Ranongga Island. The huge quake pushed much of the island up, raising the coral reefs that ringed the island above the water. In the course of a few minutes, Ranongga Island acquired several meters of new beach. The newly exposed reef forms a gray rim along the eastern shore of the island in the left image, acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on April 12, 2007. In the right image, taken on March 31, 2006, the shallowly submerged reefs color the water a lighter shade of blue. The uplift may be more dramatic than the images show. When ASTER took the 2007 image, the tide was 29.4 centimeters higher than it was when the 2006 image was taken, and yet the uplift is still visible. The lush vegetation that covers the tropical island is bright red in this image, which is made from both visible and infrared light. Out of its aquatic environment, the reef died, becoming the foundation of new land. Such evolution is common in earthquake zones in the Pacific and Indian Oceans. During the December 26, 2004, earthquake that generated the massive Indian Ocean tsunami, Simeulue Island was lifted as much as 150 centimeters (4.9 feet), exposing the reef that surrounded it. A similar set of exposed fossilized reefs on the shores of Papua New Guinea, near the Solomon Islands, provided proof that wobbles in the Earth's orbit trigger ice ages.

| Title |
Eruption of Langila Volcano, New Britain |
| Description |
Since June 2, 2005, Langila Volcano, in Papua New Guinea?s West New Britain province, has erupted continuously, according to the International Federation of Red Cross and Red Crescent Societies. The volcano has discharged unusually heavy loads of ash. Initially, winds carried the ash clouds northward over the ocean. Changing winds, however, have begun returning the ash to the island. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]), flying on NASA?s Terra [ http://terra.nasa.gov/ ] satellite captured this image on June 13, 2005. A cloud of volcanic ash appears over the ocean, north of the Langila Volcano near the bottom right corner of the image. Approximately 10,000 people live in the volcano?s vicinity, in a remote area where radio communication is unreliable and access is only by boat or helicopter. Because lightning damaged instruments at the region?s volcano observatory, the Langila Volcano must be monitored visually. Meanwhile, fallen ash has damaged food crops and exacerbated the dry season. It has also caused widespread eye and respiratory irritation. On June 6, 2005, visitors from the West New Britain provincial disaster office determined that the volcano had affected more than 3,000 residents. This number is expected to rise to as many as 6,000. The provincial authorities are encouraging voluntary evacuation. NASA image created by Jesse Allen, Earth Observatory, using data obtained from the MODIS Rapid Response team. |

Manam, Papau New Guinea |
| Description |
An unusually clear day in Papua New Guinea provided the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite with this view of the Manam Volcano on May 9, 2006. The volcano is one of the country's most active volcanoes, and it has erupted frequently since 1616. Its current eruption began on October 24, 2004 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=12556 ], when the volcano erupted explosively. Though MODIS has detected many ash plumes from the volcano since that time, none have been so large. Evidence that the volcano was still rumbling on May 9 comes from the tan plume of ash that streams southeast from the mountains's summit.

Manam, Papau New Guinea |
| Description |
The Manam Volcano emitted a plume of volcanic ash and/or steam on May 23, 2006. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard NASA's Terra [ http://terra.nasa.gov/ ] satellite took this picture the same day. In this image, a volcanic plume flows westward away from the island and toward the mainland. Clouds hover over Manam's summit, a common occurrence over volcanoes. Also visible in this image are two brown-green sediment plumes flowing northward into the ocean from mainland Papua New Guinea. Lying just 13 kilometers (8 miles) off the coast of mainland Papua New Guinea, the island of Manam is only 10 kilometers (6 miles) wide. It is also one of Papua New Guinea's most active volcanoes. The volcano is built from layers of hardened lava, ash, and volcanic rocks. The volcano's summit sports two craters, the southern crater having been the more active in recent history.
