MULTI-TEMPORAL INTERFEROMETRY FOR DETECTING AND MONITORING LANDSLIDE: MOUNT KINABALU EARTHQUAKE CASE

摘要

Landslide in Malaysia commonly occurs due to a combination of more than one cause. Due to infrequent occurrence of earthquake in Malaysia, the study on landslide due to combination earthquake and rainfall usually neglected, however, unlike any other state in Malaysia, Sabah recorded as Malaysia's most active seismic region and medium intensity. On the 5th June, an earthquake with a magnitude of 6.0 struck Ranau, Sabah, Malaysia, and another mainshock were felt on September 2017 and March 2018. This 2015 earthquake has triggered many questions regarding their nature of recurrence, characteristics in size and mechanism in and its surrounding region. This study aims to assess slope instability on Mount Kinabalu Earthquake case using multitemporal InSAR data using ALOS-2 from 2015 to 2018. Preliminary results indicate that multi-temporal InSAR analysis can provide us with temporal ground movements and understanding of the local earthquake activities in the study area.
