Vulnerability Index of Critical Infrastructure in Greater Kuala Lumpur Fault Zone, Malaysia

The Greater Kuala Lumpur (Greater KL) region, a pivotal hub of Malaysia's economic growth, confronts a burgeoning challenge amid rapid urbanization. Unprecedentedly, it is vulnerable to seismic reactivation possibilities from the dormant Kuala Lumpur Fault Zone (KLFZ). With a comprehensive integration of geospatial technologies, to dissect the geological intricacies of the KLFZ and assess the vulnerability of critical infrastructure within Greater KL. The research aims to bridge the realms of geology and infrastructure engineering, providing actionable insights for policy decisions and urban planning to enhance the region's resilience to seismic events. The problem statement underscores the urgent need for a comprehensive investigation into the interplay between the geological characteristics of the KLFZ and the vulnerabilities in infrastructure. Despite the economic significance of Greater KL, a notable research gap hinders effective mitigation and preparedness strategies. The aim is to unravel the distinctive features of the KLFZ, assess infrastructure vulnerability, and inform policies for safeguarding against potential seismic threats. The methodology unfolds systematically, employing geospatial analysis, remote sensing, and geological data. The research adopts a meticulous data acquisition approach, integrating Sentinel-2 imagery and a seismotectonic map of Malaysia to delineate the fault zone. The extraction of critical infrastructure is conducted with precision, considering the guidelines from the U.S. Cybersecurity and Infrastructure Security Agency. The subsequent steps involve buffer zone creation, overlay analysis, and data classification to develop a vulnerability index. The expected outcome revolves around a comprehensive understanding of the KLFZ and its implications on infrastructure vulnerability. The methodology employs detailed mapping and geospatial analysis, providing insights into fault characteristics, seismic hazards, and critical infrastructure susceptibility. The research aims to contribute a robust foundation for disaster preparedness, urban planning, and engineering strategies, fostering the safety and stability of Greater KL against seismic risks. This research contributes to the broader discourse on urban resilience and disaster management, emphasizing the significance of geomatics in addressing the complex challenges posed by active fault zones or the possibilities of reactivated fault zones. The findings hold practical implications for policymakers, urban planners, and geospatial professionals, offering a nuanced perspective on the intricate relationship between geological factors and infrastructure vulnerabilities in dynamic urban landscapes. In conclusion, this research endeavours to unravel an inform evidence-based decision-making, contributing to the sustainable development and safety of the Greater KL region.
