From Thailand to Sri Lanka, on both sides of the Bay of Bengal, there were reports of animals running to safety well before the December 26, 2004 southeast Asia tsunami struck.

Sri Lanka is far from the epicenter of the Sumatran earthquake. Did the earthquake supply the only warning?

Or is it possible that the tsunami itself radiated seismoacoustic signals of sufficient strength and frequency for some animals (such as elephants) to detect and interpret long before it struck shore?

Srinivasan Jagannathan and Nick Makris of MIT (makris@mit.edu), along with Purnima Ratilal from Northeastern University, investigate this possibility through numerical models that consider the seismic-radiation potentials of tsunamis in deep water and on the continental shelf. Such information is likely to determine additional ways to detect warning signs of tsunamis. (1pAOb2)


Do students change their accents shortly after they enroll in college? How can ultrasound trigger healing in bone fractures that are otherwise very stubborn to mend? Could airplane noise lower a student's test scores?

These and other questions will be addressed at the joint meeting of the Acoustical Society of America (ASA) and the Canadian Acoustical Association (CAA), to be held May 16-20, 2005 at the Hyatt Regency Vancouver Hotel (655 Burrard Street, Vancouver, BC V6C 2R7, Canada, 604-639-4820). Over 1050 papers will be presented, making it one of the largest acoustics meetings to date. ASA (http://asa.aip.org) is the largest scientific organization in the United States devoted to acoustics. CAA (http://www.caa-aca.ca) is a professional, interdisciplinary organization devoted to acoustics in Canada.

WORLD WIDE PRESS ROOM

We encourage you to visit ASA's "World Wide Press Room" (located at http://www.acoustics.org/press) before and during the meeting. By the week of May 2, the site will contain lay-language versions of selected meeting papers. These papers will enable you to cover the meeting, even if you can't leave your desk.

MEDIA INQUIRIES

Reporters covering the meeting can receive a complimentary press badge to attend all sessions. Please fill out the reply form if you are interested in attending the meeting. Ben Stein (bstein@aip.org, 301-209-3091) and Martha Heil (mheil@aip.org; 626-354-5613) of the American Institute of Physics will be available both remotely and on-site to facilitate your requests, from contacting speakers at the meeting to obtaining background material on meeting topics.
