Development of Nationwide Vs30 Map and Calibrated Conversion Table for Indonesia using Automated Topographical Classification

A nationwide Vs30 map for Indonesia was developed based on
automated topographic classification from 90-m grid digital elevation data and
their correlation with Vs30. Automated topographic classification has been
proposed by Iwahashi and Pike (2007) and a procedure to convert topographic
class into Vs30 maps has been developed by Imamura and Furuta (2015) based on
Vs data from J-SHIS (Japan Seismic Hazard Information System). In order to be
suitable for Indonesia, calibration work according to Imamura and Furuta’s
procedure should be conducted since the geotechnical conditions in Japan may
not be the same as in Indonesia. This paper presents adjustment of the Vs30
correlation by Imamura and Furuta to convert topographic class into Vs30 and
construct a Vs30 map of Indonesia. This correlation was calibrated by using Vs
data from BMKG (Indonesian Agency for Meteorological, Climatological, and
Geophysics) as well as standard penetration test logs that were collected by the
authors. Utilization of local field measurement data will certainly enhance the
reliability of the Vs30 map. The developed nationwide Vs30 map will be very
useful for disaster mitigation programs and for preliminary design of earthquake
resistant buildings and infrastructure in Indonesia.
