The largest disaster of 2010 so far continues to unfold. Aftershocks are hitting Haiti. Understanding the dynamics of the fault is crucial for planning evacuation and relief operations. TerraSAR-X can image the whole affected area independent of cloud conditions. Using correlation matching DLR extracted the east-west and north-south shifts. The results show upto 2.8m shift along the fault line.

The openlayers project and telascience have started putting together a web portal for the data flowing through from the disaster charter and other sources. EROS imagery shown in the previous post will be available soon.

Satellite images of the devastated area of Port-au-Prince after the 7.0 magnitude earthquake in Haiti

Wednesday, January 20th, 2010

On Tuesday 12th January 2010, a 7.0 magnitude earthquake struck the Caribean country of Haiti.The epicenter was only 10 miles away from the capital Port-au-Prince. 75000 people have been confirmed dead and the death toll is likely to rise. Infrastructures have been hit badly and and satellites images show the extent of the damage. Multiple images from ImageSat International EROS-A and EROS-B satellites are being acquired over the devasted area of Port-au-Prince and surounding areas. The images are donated to any agencies which can benefit from them. Please contact Apogee for any requests. The extent of the damage as well as thousands of people gathered in public squares can be seen in the subset images below.

Giant Iceberg moving toward Australia

Thursday, January 14th, 2010

A giant iceberg known as B17B broke off Antartica’s Ross Ice Shelf 10 years ago and had drifted 1,700 kilometers from Australia’s coast. Since December, the iceberg has been slowly breaking up and melting due to warmer water.

The image below has been acquired with TerraSAR-X on the 15th December and clearly shows the main iceberg breaking up into fragments.
