AbstractThe Government of Indonesia has committed to deploying a network of 500 strong-motion sensors throughout the nation. The data from these sensors have the potential to provide critical near-real-time information on the level of ground-shaking and potential impact from Indonesian earthquakes near communities. We describe the implementation of real-time "ShakeMaps" within Indonesia's Agency of Meteorology, Climatology and Geophysics (BMKG). These ShakeMaps are intended to underpin real-time earthquake situational awareness tools. The use of the new strong-motion network is demonstrated for two recent earthquakes in northern Sumatra: the 2 July 2013 MW 6.1 Bener Meriah, Sumatra and 10 October 2013 MW 5.4 Aceh Besar earthquakes. The former earthquake resulted in 35 fatalities with a further 2,400 reported injuries. The recently integrated ShakeMap system automatically generated shaking estimates calibrated by BMKG's strong-motion network within seven minutes of the Bener Meriah earthquake's origin assisting emergency response efforts. Recorded ground-motions are generally consistent with theoretical models. However, more analysis is required to fully characterise the attenuation of strong ground motion in Indonesia.
Summary(Plain Language Summary, not published)
In the wake of large earthquakes around the world, it can take days to determine the full impact of the disaster. Relying solely on media reports to dispatch an appropriate level of emergency search and rescue would delay the humanitarian response, prolong suffering, and potentially increase the death toll. This contribution outlines the processes undertaken and challenges that were overcome to deliver a real-time "ShakeMap"system for Indonesia. The system is designed to provide rapid situational awareness on the likely societal impacts following significant earthquakes in Indonesia.
