Magnitude 6.3 quake in central Java |
| Description |
A powerful earthquake rattled Yogyakarta, Java, Indonesia, in the early morning hours of May 27, 2006. The quake destroyed more than 60,000 houses in the city, and killed an estimated 6,234 people, reported the World Health Organization on June 6. Though Indonesia experiences frequent earthquakes, the May 27 quake was unusual in that it was centered about 10 kilometers under the Earth's surface, according to the United States Geological Survey (USGS). Most earthquakes in Indonesia occur deep under the Earth's surface where the slab of the Earth's crust that carries Australia (the Australia Plate) sinks beneath the Sunda Plate on which the islands of Indonesia ride. Earthquakes occur in the sometimes-messy grind of colliding plates, but these are centered deep below the Earth's surface. The May 27 earthquake happened near the surface along a fault in the Sunda Plate, about 20 kilometers south-southeast of Yogyakarta. This image shows the topography of the landscape near the earthquake epicenter. Yogyakarta sits in a broad valley between two groups of roughly north-running mountains. The towering Merapi Volcano caps the northeast end of the valley. Behind it is the single peak of the Sundoro Volcano and a cluster of small peaks in the Dieng Volcano Complex. The Slamet and Cereme Volcanoes are west of Merapi in the upper-left corner of the image. The earthquake occurred along a fault east of the mountains that frame Yogyakarta to the east. The image was created from data collected by the Shuttle Radar Topography Mission. The earthquake is not the only geologic activity to threaten the region: the Merapi volcano was also rumbling at the end of May. The volcano sent clouds of hot gas and lava down its slopes on June 6, prompting the evacuation of 11,000 people, said news reports. The ASTER sensor on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured an image [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13628 ] of the volcano in action on June 6. The volcano had been showing signs of increased activity since April, but activity picked up after the May 27 earthquake. While volcanic activity and earthquakes are often connected, it is not clear if the May 27 earthquake is directly linked to Merapi's activity, said the USGS. The same underlying geologic processes may have triggered both events.

Fires on Borneo
| Title |
Fires on Borneo |
| Description |
Thick smoke hung over the island of Borneo when the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite passed overhead on October 5, 2006. The sensor detected scores of fires (locations marked in red) in the Kalimantan province of Indonesia, and smoke billowed northward over the Malaysian part of the island, as well. The fires occur annually in the dry season (August-October), caused mainly by land-clearing and other agricultural fires. Fires escape control and burn into forests and peat-swamp areas. Fires in peat—thick layers of dead, but un-decayed vegetation—are extremely smoky and difficult to put out. Some of the blazes will only be extinguished when the monsoon rains start in upcoming weeks. You can also download a 250 m resolution KMZ file [ http://earthobservatory.nasa.gov/NaturalHazards/Archive/Oct2006/Borneo.A2006278.0250.250m.kmz ] (1.9 MB) for use with Google Earth.

Fires on Borneo and Sumatra
| Title |
Fires on Borneo and Sumatra |
| Description |
In Sumatra and Indonesia, seasonal fires and the thick smoke they produce plagued the islands for nearly two months in late 2006. Beginning in mid-September 2006, the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] and Aqua [ http://aqua.nasa.gov ] satellites detected numerous fires in daily images of the area. This image was captured by Aqua MODIS on November 5, 2006. Active fire locations are marked with red dots. Thick smoke spreads between the two islands, the grayish haze mingling with brighter clouds. Many factors contribute to the fires, which usually start from agricultural burning, but often spread into adjacent tropical forest. When the forests have been degraded by logging, they become much more prone to fire. In addition, climate fluctuations, such as droughts that occur in concert with El Niño events, can make the fires worse. During droughts, the typically soggy forest floor of these lowland forests dries out. The thick layer of dead vegetation on the forest floor, peat, becomes flammable and produces enormous quantities of smoke when it burns.

Floods in East Africa
| Title |
Floods in East Africa |
| Description |
Severe drought early in 2006 followed by widespread flooding [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13795 ] during August crippled Ethiopia. In late October and early November, the disaster continued to develop as heavy rain once again sent the Wabe Shebele River over its banks. The swollen river grew to twice its normal size, inundating towns that line its fertile banks, reported the World Food Program [ http://www.alertnet.org/thenews/newsdesk/WFP/4d4580f3cc2d9d49654e66a8daf84c16.htm ]. More than 60 people died in the floods, and many more were impacted. On November 1, 2006, skies cleared, providing the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite a clear view of the floods in southeastern Ethiopia. The Wabe Shabele spreads several kilometers across its flood plain, its water ranging from inky black to light blue. The scene is shown in infrared-enhanced false color to highlight the presence of water on the ground. In this color combination, made with both visible and infrared light, water is typically black, as it is in the lower reaches of the river in this image. Elsewhere in the scene, however, water is light blue because sediment in the water scatters light. The pale blue color blends with the light green of newly growing plants, making it difficult to tell just how extensive the floods are on the west bank of the river. Other waterways on either side of the Wabe Shabele are also filled with mud-laden, light blue water. The lower image, taken on October 7, shows the Wabe Shabele under normal conditions. Though the river is prone to flooding, the attractiveness of living along its banks is clear from this image. Little vegetation is growing in the arid region except along the river's banks, which are lined in green. Conditions changed by November 1. The same rainfall that caused the floods also spurred plant growth, and the landscape went from a barren tan-pink to verdant green. Lines of high clouds, pale blue and white in this false-color image, are scattered across both images. Like much of East Africa, southeastern Ethiopia goes through a regular cycle of floods and droughts. The cycle is in part driven by El Niño, a cyclical warming of ocean waters in the central and eastern Pacific that can alter weather patterns around the world. In general, El Niño causes drought in some regions, such as Indonesia, Australia, and the Philippines, while bringing excess rain to others, including East Africa and the southwestern United States. In September 2006, NASA's JASON satellite recorded a weak El Niño [ http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17419 ] in the tropical Pacific Ocean. At the same time, drought [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13943 ], was settling in over Australia, and heavy rain pounded East Africa.
