Description:	Malaysia is stituated at the edge of the Pacific Ring of Fire, thus, is highly vulnerable to catastrophic seismotectonic disasters. The 6.1 Mw Earthquake, on 5th June 2015 at Kinabalu caused 18 casualties, massive damage and losses to the socio-economic of Sabah. This event triggered nation wide awareness on the importance of preparedness for disaster risk reduction. This recent seismo-tectonic activity indicates the need of advanced mapping and monitoring tools to provide reliable spatial and temporal information of the events. Considering the number of fatalities and substantial losses of property in Sabah due to the single recent Ranau Earthquake and its cascaded geohazards events, thus, a multi-scale and generic seismic hazard mapping for understanding such disaster in Malaysia context is critically needed. Furthermore, the local government recommended the use of advanced geodetic measurement along active fault zones in order to elucidate and monitor earthquakes occurring in the regions. The first objective of this study is to develop the Earthquake Geo-Cataloging System for geohazards (MEQDRR) events along with their detail characterization and unique identification (ID) utilizing GLIDE system for ease of identification of events geohazards and cascading hazards. In this study the country's earthquake records are cataloged for the first time since 1897, with a unique ID and standard naming protocol associated with an international database system. Secondly, remote sensing data of multi-scale, multi-resolution, both IfSAR and LiDAR were used for mapping, determination of parameters, seismotectonic geohazard assessment and element-atrisk analysis. Categorized into 3 causal factor groups of 1) Geomorphological-seismic causal factors (GMSF), 2) Geological-seismic causal factors (GSF), and 3) Anthropogenic-seismic causal factors (ASF). These factors were used in geospatial analysis to generate element-at-risk geohazard maps and exposure map for disaster risk. Thirdly, the developed geospatial data and analysis was utilized to validate seismotectonic features in the field with knowledge driven approach from local experts. Geomorphology and signs of seismotectonic activity derived from remote sensing data combined with local expertise knowledge are evaluated from site observation. These maps were used in extensive site investigations allowing better understanding of processes, causes and impacts of earthquake. Finally, outreach programmes were conducted with local communities in villages that were exposed and directly effected by the earthquake. Demonstrating science from laboratory to practice and from words into actions, therefore, supporting the priority of actions to achieve the goal of Sendai Framework for Disaster Risk Reduction (SFDRR) 2015-2030. It is also used as a medium for communication with the local community in the DRR activities. This include the increase of public awareness, disaster preparedness and local small scale mitigation by local communities post to annual outreach programmes with the same exposed communities. This study substantially improved risk communication based on science and later co-developed Community-based Disaster Risk Reduction supported by local champions for developing a resilient society. This research addresses scientific knowledge-based decision emphasizing on local risk adaptation and multi-hazard risk reduction. As a way forward, this study promotes a Transdisciplinary Approach and evidence-based decision making for DRR.,Ph.D.
