Television reported some persons went to the beach to monitor the receding seawater. Persons in Padang, West Sumatera, Mentawai Island, and Muko muko-Bengkulu evacuated, some self-evacuating, and many waiting for the local BMKG in Padang for clarification. Some issues with the media television broadcast of the warning were noted, and are now being discussed with the National Commission for Broadcasters. Based on television reports, the UNESCO’s Indian Ocean Tsunami Information Center indicated that while there was confusion and panic in the community, it was better than in 2012. Indonesia’s National Tsunami Warning Center (BMKG InaTEWS) issued its first bulletin in less than 5 minutes, the second bulletin in less than 10 minutes, and the fourth bulletin (ending of its national tsunami warning) after about 2 hour 40 minutes. Public bulletins are currently available from the India and Indonesia TSPs. The TSPs provide tsunami alerts directly to country NTWCs, and each country uses the advice to assess and issue warnings and advisories to their populations. Interim services were provided by the PTWC and JMA from 2005-2013. In April 2013, Australia, India and Indonesia assumed responsibility as the official TSPs for the Indian Ocean. TSP Exchange bulletins to IOTWMS National Tsunami Warning Centers (NTWC) were issued by Australia (13:06 – 16:57, 7 bulletins), India (12:55 – 15:17, 3 bulletins), and Indonesia (12:49 - 15:53, 4 bulletins). Public exchange bulletins were issued by the UNESCO IOC Indian Ocean Tsunami Service Providers (TSP) in India (12:56 – 15:23 UTC, 3 bulletins), and Indonesia (13:19 – 15:53 UTC, 4 bulletins). In contrast, shallow thrust faulting in subduction zones can cause destructive tsunamis, such as the M9.1 2004 Sumatra earthquake that generated 40-m tsunami runups locally, and propagated across the Indian Ocean killing 228,000 in 15 countries. This intraplate earthquake had a strike-slip faulting mechanism, which rarely generates dangerous tsunamis (see PTWC RIFT forecast below). The USGS reported the earthquake occurred at 12:49 UTC, 4.908 °S 94.275 ☎, with a depth of 24.0 km (14.9 mi), roughly in the center of the Cocos Basin, and 600 km southwest of the Sunda-Java Trench off Sumatra, northern Indonesia. The maximum wave amplitude was 12 cm at Tanahbala. The M7.8, shallow, Indian Ocean earthquake generated a small tsunami that was recorded on Indian Ocean coastal sea level gauges in Australia (Cocos, Christmas Islands), Indonesia (Tanahbala), Maldives (Gan, Male, Hanimadhoo), and Mauritius (Rodrigues Island). 02 March 2016, Mw 7.8 Southwest of Sumatra, Indonesia Earthquake & Tsunami
