It's preparedness at the international level that he's concerned about. He and other tsunami experts say a lack of coordination among countries could seriously weaken the effectiveness of otherwise sophisticated new early-warning systems set to go online this year. India has installed six of 10 planned wave sensors off its coast, and the Indian Ocean Tsunami Warning System (IOTWS), designed by a consortium of German scientists, begins operating in November. But India, concerned about triggering sensors during covert nuclear-weapons tests, doesn't share its seismic data, and it's not clear yet whether India will give out buoy data. Costas Synolakis, director of the Tsunami Research Center at the University of Southern California, is also frustrated that India, Indonesia and Germany wasted time developing their own buoys and pressure sensors, which will require time to fine-tune, when effective technology already exists. The U.S. network, which NOAA runs, consists of 40 buoys, deployed mostly along the coastal U.S., and has forecasted a handful of minor tsunamis.
