Mentawai Gap–Tsunami Earthquake Risk Assessment (MEGA-TERA)
The Mentawai Gap–Tsunami Earthquake Risk Assessment (MEGA-TERA) is a joint project between Schmidt Ocean Institute (SOI), the Earth Observatory of Singapore (EOS), the Indonesian Institute of Sciences (LIPI) and the Institut de Physique du Globe de Paris (IPGP). Seismic reflection, bathymetry, 12kHz sub-bottom profiler and magnetic data were acquired on board the SOI R/V Falkor from May 23 to June 29, 2015, from Singapore to Singapore. The scientific objective of the Mega-Tera experiment is to quantify the tsunamigenic potential of the Mentawai gap region. Satish Singh (EOS/IPGP) was the Chief Scientist and Nugroho Hananto (LIPI) was the Co-chief Scientist on board the vessel. Three scientists from EOS, two from IPGP, and four from Indonesia participated in the experiment. Seismic reflection instruments were rented from Sea and Land Technology (SALT), who also provided technical support (6 engineers) for the seismic data acquisition. This team was completed by three engineers from SOI along with a marine operation team (20). SOI also provided an outreach person. The details of the experiment can be found here.
