Brief Account of the Post-event survey 2010 Pagai-Mentawai islands tsunami earthquake in Indonesia

The tsunami earthquake earthquake occurred on 25 of October 2010 in the Indian Ocean about 79 km south-west of Mentawai islands. The tsunami caused severe damage and claimed many victims in some coastal villages. The main purpose of the survey was to measure the inundation and the run-up values as well as to ascertain the possible morphological changes caused by the wave attacks. Attention was particularly focussed on the most affected villages, that is Muntei Barubaru and Malakopak in Mentawai islands. The most severe damage was observed in the Muntei Barubaru. Most places were hit by three significant waves with documented wave height often exceeding 5 m. The maximum runup value (17.00 m) was measured at North Pagai, where also the most impressive erosion phenomena could be found.
