Abstract

The limitation of clear historical records of the past large earthquake from Lembang fault, West Java, Indonesia, is making the geological records playing the role as the primary information sources. However, weathering and bioturbation are very intensive in this tropical country, and high potentially destruct the geological tracks of the fault on the outcrop. Sedimentation records in the tectonic lake and the other tectonic basins could be the significant alternatives with better preservation. One of the best options for the study of paleoseismology and its effects on the aquatic environment is the sag pond formed by fault movement. This environment and resultant stratigraphy is directly influenced by the fault activity and associated with the weathered profile as the marker of environmental changes. The deformation could be affecting the accommodation space, water level fluctuation, and sedimentary flux, which influence the water chemistry. The diatoms as the sensitive bio-indicator could respond to water level fluctuation and sedimentary flux. This paper highlights and proposed the diatom and geochemical perspective to reveal the records of earthquake movement based on the environmental change of sag pond sedimentation feature.
