Following the tremendous 9.1 earthquake in the Indian Ocean, it is interesting to look at current earthquake activity and the large number of aftershocks, one as high as 7.3 near the Nicobar Islands. There is certainly a lot of interest in creating an early warning system there similar to what we have in Hawaii, Alaska, and other areas of the Pacific coast. The International Tsunami Information Center is headquartered in Hawaii. An alert issued at two o'clock zulu time mentioned that there might be the possiblity of a tsunami associated with the Sumatra quake.
