ASEAN Weekly Disaster Update, 24-30 December 2018
Regional Summary of Week 52, and Outlook for Week 1
In Week 52, tropical depression “Usman” made landfall in Philippines wrecking havoc. A total of 6 earthquakes of M5.0 and above were reported this week (BMKG and USGS).
An earthquake of M7.2 was reported near Governor Generoso, Davao Oriental. A tsunami warning was triggered but cancelled after 2 hours. No damages was reported thus far by NDRRMC as of 30 Dec 2018 1200hrs (UTC+7). Public have been advised to avoid sea travel following an earthquake warning as rough seas might occur.
Mt Soputan erupted on 16 Dec at 0540hrs (UTC+7) with a permanent danger zone of 4km radius and 6.5km for the southwest-west sector of the opening area of the crater to avoid the threat of lava flow and avalanche hot clouds.
The Volcanology and Geological Disaster Mitigation Center (PVMBG) estimated that the volcano reduced to between 40 million and 70 million cubic meters in size from a mass of about 150 million to 180 million m3, following eruptions that occurred between Dec. 24 and 27. "Given that the remaining volume is not too large, the potential for another tsunami is relatively small, unless there is a reactivation of faults or fault structure in the Sunda Strait,” PVMBG Secretary Antonius “Purbo” Ratdomopurbo said on Saturday.
Alert Level 2 status prevails over Mayon Volcano and Kanlaon Volcano, which means that the volcanoes are undergoing a moderate level of unrest. Permanent danger zones are 6km and 4km respectively.
Travellers to volcanic areas are advised to take note of local government advisories before ascending and evacuation notices in high-risk areas.
All reported disasters were within the coping capacity of the member states.
