Earthquake Spawns Tsunamis
| Title |
Earthquake Spawns Tsunamis |
| Description |
The Indonesian province of Aceh was hit hardest by the earthquake and tsunamis of December 26, 2004. Aceh is located on the northern tip of the island of Sumatra. Early Western media attention was focused on Sri Lanka and Thailand, even though the earthquake epicenter was closer to Aceh, and the largest waves struck the northwestern coast of Sumatra. On Decemebr 29, estimates of the death toll in Indonesia were over 80,000more than half the global total. The town of Lhoknga, on the west coast of Sumatra near the capital of Aceh, Banda Aceh, was completely destroyed by the tsunami, with the exception of the mosque in the city's center. These high-resolution satellite images, acquired by Space Imaging's [ http://www.spaceimaging.com/ ] Ikonos satellite, show Lhoknga before (lower) and after (top) the earthquake and Tsunami. Almost all the trees, vegetation, and buildings in the area were washed away. Behind the town, low-lying agricultural areas remained covered with water 4 days after the disaster, and sand on the nearby beaches was completely removed. The wave height [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=12645 ] might have exceeded 15 meters (50 feet) when it struck the shore. Equivalent devestation extends 225 km southeast along the Sumatran Coast, in a band up to 3 km (1.9 miles) deep. Imagery from the Moderate Resolution Imaging Spectroradiometer [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=12644 ] (above) shows the affected area as a thin strip of brown along the coast.

North Reef Island, Andaman S

| Title |
North Reef Island, Andaman Sea |
| Description |
On December 26, 2004, one of the largest earthquakes in recorded history struck offshore of the island of Sumatra, Indonesia. The ocean floor heaved in some places and sank in others, creating catastrophic tsunamis that raced across the Indian Ocean. Hundreds of thousands of people died as the waves struck coastlines from Thailand to Sri Lanka to Somalia. In addition to tsunami damage, satellite images of reefs, islands, and coastlines identified signs of permanent elevation changesinking or upliftalong the fault between the Indo-Australia and Burma plates. [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=12640 ] In places such as North Reef Island, shown in this pair of images from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [ http://asterweb.jpl.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite, the quake lifted the reefs permanently out of the water. The images use visible and infrared light detected by ASTER to make different land surfaces stand out clearly from one another: water is blue, vegetation is red, coral or bare sand appears white. In the "before" image, from December 2, 2004, the submerged reef creates a bright blue glow around the island. In the "after" image, from February 4, 2005, the white coral stands completely up out of the water. It is even tinged with red, which suggests the exposed coral had died, and algae had colonized it. In the weeks and months after the earthquake, satellite images provided broad coverage of an area where ground-based observations were initially very limited. A team of scientists led by Caltech Ph.D. geology student Aron Meltzner discovered changes in elevation along nearly 1,600 kilometers (994 miles) of the tectonic plate boundary. The images revealed that the earthquake rupture extended 100 kilometers (62 miles) farther north than estimates based on seismic and Global Positioning System (GPS) data suggested. The feature article Rise and Fall: Satellites Reveal Full Length of Tsunami-Generating Earthquake [ http://earthobservatory.nasa.gov/Study/Aceh/aceh.html ] describes how scientists used satellite images to map the length of the earthquake rupture zone. The article includes additional satellite and ground-based images of elevation changes resulting from the 2004 Aceh-Andaman earthquake.
