Hurricane Katrina and its aftermath
Hurricane Katrina severely pounded the Gulf Coast of U.S. with great force at daybreak on the 29th of August. Arriving with 145 mile an hour wind speed, the storm left more than a million people in three U.S. states without power and submerged highways. Hurricane Katrina, formed in the Bahamas in mid-August and struck South Florida on 25 August, killing nine people and leaving a million more without electricity. European Space Agency’s multisensor Envisat satellite has gathered a unique view of Hurricane Katrina in the Gulf of Mexico. Envisat simultaneously acquired these images at 1550 UTC (1150 US Eastern Daylight Saving Time) on 28 August, with its Medium Resolution Imaging Spectrometer (MERIS) and Advanced Synthetic Aperture Radar (ASAR). While an optical image shows characteristic spiralling cloud patterns, a simultaneous radar observation pierces through the clouds to show how Katrina’s 250- kilometre-an-hour winds scour the sea surface. www.sciencedaily.com

Bangkok to introduce GPS to its fleet of taxis
Bangkok has opened the first of 150 new electronic taxi stands that will allow pedestrians to summon a taxi by pressing a green button, signaling a dispatcher to send a taxi. The devices will display the estimated arrival time and license plate number of the approaching taxi. Taxis will be equipped with GPS as part of the service. The first arch-roofed electronic taxi stand was unveiled last week outside a superstore on the city’s Phahonyotin Road, while the remaining stands are expected to be installed across the city by November. Besides helping Bangkok pedestrians easily hail taxis, the stands are meant to keep cab drivers from wasting fuel by driving around the city in search of fares. www.chinapost.com.tw

Tsunami shifts Bangkok southwest…
Bangkok has moved about nine centimetres (3.5 inches) horizontally southwestwards because of the December 26 earthquake that measured 9.0 on the Richter scale and sent devastating tsunamis across the Indian Ocean. The tourist island of Phuket also moved 32 centimetres (12.6 inches) southwestwards since the quake, said the Chulalongkorn University researchers, who used GPS satellites to measures the shifts during a January 20-24 survey. Researcher Itthi’s survey engineering department at Chulalongkorn is collecting data from six other locations in Thailand to get a better picture of how the nation’s geography has changed, the Nation newspaper reported.
