The world today enjoys great benefits from the use of technology. Ease of information, accessibility and influence has increased tremendously over the generations. The smart city implementation can benefit from the focus use of applications built to address the impact of adverse weather. In this chapter, we explore the use in particular of geospati...

Several widespread debris flow disasters stroke Peninsular Malaysia in between 2021 and 2022, scattered across the country. It was the first time for this hazard being nationally recognised as a type of geological disaster in the country. Debris flow disaster is not a new phenomenon. It had been recorded since 1995, however, in the past they were i...

The measurement of global progress in implementing a Sendai Framework for Disaster Risk Reduction (SFDRR) targets should be able to report on a set of 38 indicators including those related to disaster damage. The ability of a hazard-specific database (e.g. landslide database in this case) in providing information that meets the SFDRR target is not...

Disaster loss indicators compatible with DesInventar Sendai were delineated to facilitate reporting to the Sendai Framework for Disaster Risk Reduction (SFDRR), and enable monetary valuation of disaster impacts in Malaysia. A standard means of collecting disaggregated information to ensure compliance to SFDRR targets is a challenge for many governm...

Pengurangan risiko bencana perlu diarusperdana dan diintegrasikan dalam proses pembangunan negara.

Rapid-moving landslides occurred in many locations during the 2009 Padang earthquake, Sumatra. We interpreted satellite images, performed field surveys, in situ dynamic cone penetration tests, and laboratory analyses for mineralogy and physical and mechanical properties. We found that landslides occurred at 159 locations in an area of 64 km², and t...

Communication is an essential aspect of preparing for, avoiding or responding to the occurrence of natural geohazards. As such, it forms an integral part of any strategy to enhance resilience to geohazard events. Conversely, inadequate or lack of communication is a common factor in failing to minimise the risks involved. Communication about geohaza...

This study revisits the Bukit Antarabangsa, a hilly topographic region of Ampang Jaya where a number of landslides occurred between year 1990 and 2010, resulted in 65 lives perished. Among those fatal landslides were the collapsed of a block of Highland Towers condominium, Taman Hillview bungalow and Taman Bukit Mewah housing estate. In examining h...

Disasters disrupt normalcy and present challenges for development policies. The impacts of any disaster–whether triggered by climate change, natural hazards or other man-made events–can be compounded by decisions that intentionally or unintentionally amplify rather than reduce damage. Disasters have impacts across all sectors, necessitating multi-...
