Early Reports of the March 28, 2004 Earthquake

By Rachel Tardiff

 

Three months after a devastating earthquake and tsunami hit coastal areas of the Indian Ocean, an aftershock ranking 8.7 on the Richter Scale occurred at 11:09PM (local time), followed by another 6.0 aftershock 30 minutes later.  The epicenter of the earthquake was located 18 miles deep off the coast of Sumatra (near the island of Nias, which is ~900 miles from Jakarta, Indonesia).  It occurred on a segment of the same fault line as the December 26, 2004 event; however it was on a southern-facing segment, which is believed to have minimized the effects of any potentially devastating tsunamis in the nearby coastal areas.  The quake is believed to have caused severe destruction of homes and buildings, killing many and trapping others, especially on nearby Nias Island, Simeulele Island, and Sumatra.  The quake caused mass panic in the coastal communities that suffered greatly from the devastating tsunami of 3 months ago.  After being shaken out of their beds, hearing the alert sirens, warnings, and calls for evacuation, people fled their houses by the thousands and ran for higher ground in case another tsunami were to hit.  A monitor in the Cocos Islands (1,400 miles west of Australia, and southwest of the epicenter) detected a small tsunami, only creating an ocean disturbance of approximately 4 inches.  The Pacific Tsunami Warning Center and Japan’s warning centers detected the quake and immediately alerted the authorities in the potentially affected areas, advising the close monitoring and evacuations of low-lying coastal areas within a 600-mile radius of the epicenter.  Most countries issued tsunami warnings that were eventually withdrawn once officials had announced that if a tsunami had not hit within 6 hours of the earthquake, there was little chance that one would occur.  The U.S. State Department alerted all posts in the area: embassies in the region have been aiding host governments and aid/relief agencies to collect pertinent and accurate information, and are on alert to possibly help in other ways if necessary.  The American Red Cross (ARC) continues its relief efforts in the areas hit by the December disaster.  Pending further developments and more information, the ARC will respond to this situation as well (additional funds are not believed to be necessary, due to the generous amount collected for the first earthquake and tsunami).  Note this article was written with the information provided within the first hours following the earthquake on March 28, 2005: it remains to be seen the accuracy of these early reports (from various news sources) compared to those in future news releases.
