A Quantitative Reappraisal of Historical Earthquakes in Indonesia from Uniformly Assessed Macroseismic Observations from the Dutch Colonial Period
A critical qualitative and quantitative analysis of primary sources is key to validate, improve, and supplement the census of historical earthquakes in Indonesia, which in turn is key to the assessment of regional seismic hazard. We propose to collect documentary evidence from the Dutch colonial period for Sumatra and Java. We will prepare an open-access database of our observations. When complimentary modern observations are available, these datasets will be jointly inverted to estimate effective intensity magnitudes. We will also utilise near- and far-field documentary estimates of run-up to forward model and constrain the source of the very large 1907 Simeulue tsunami earthquake.
