        INDONESIA. MW 8.7 (HRV), 8.1 (GS). ME 8.1 (GS). At least
        1000 people killed, 300 injured and 300 buildings
        destroyed on Nias; 100 people killed, many injured and
        several buildings damaged on Simeulue; 200 people killed
        in Kepulauan Banyak; 3 people killed, 40 injured and some
        damage in the Meulaboh area, Sumatra. A 3-meter tsunami
        damaged the port and airport on Simeulue. Tsunami runup
        heights as high as 2 meters were observed on the west
        coast of Nias and 1 meter at Singkil and Meulaboh,
        Sumatra. Felt (VI) at Banda Aceh and (V) at Medan. At
        least 10 people were killed during evacuation of the coast
        of Sri Lanka. Felt (IV) along the west coast of Malaysia;
        (IV) at Bangkok and (III) at Phuket, Thailand; (III) at
        Singapore; (III) at Male, Maldives. The quake was also
        felt in the Andaman and Nicobar Islands, India and in Sri
        Lanka. Tsunami wave heights (peak to trough) recorded from
        selected tide stations: about 40 cm on Panjang, Indonesia;
        about 25 cm at Colombo, Sri Lanka; 40 cm on Hanimadu, 18
        cm at Male and 10 cm at Gan, Maldives. Initial
        observations indicate about 1 meter of subsidence on the
        coast of Kepulauan Banyak as well as 1 meter of uplift on
        the coast of Simeulue. Seiches were observed on ponds in
        West Bengal, India. Broadband Source Parameters (GS):
