Abstract

Disaster relief operations during flood emergencies are often conducted under conditions of high uncertainty, limited access, and constrained resources. In such contexts, operational decisions regarding prioritization, transportation, and deployment of critical support infrastructure directly affect humanitarian effectiveness and equity. This study examines how satellite-based geohazard assessment can support disaster relief operational planning during the emergency response phase. Using recent flood events in Sumatra as a case study, the analysis draws on satellite imagery to observe flood extent, settlement exposure, access disruption, and housing damage along riverine floodplains. Rather than applying complex predictive or simulation-based models, the study emphasizes how rapid geohazard observation can be translated into operational interpretation to support timely decision-making, including transportation mode selection, prioritization under resource scarcity, and deployment of essential infrastructure such as emergency power supply. The findings indicate that geohazard-informed planning enhances situational awareness and supports more coherent and equitable humanitarian response across multiple intervention domains, including logistics delivery, medical response, psychosocial support, and child-centered relief. A conceptual pathway is presented to illustrate how geohazard assessment informs operational decisions and generates multiplier impacts across disaster relief activities. Beyond its operational relevance, the study highlights the role of evidence-informed learning in strengthening professional practice under uncertainty. The study concludes that integrating geohazard assessment into emergency response practices improves the effectiveness, accountability, and adaptability of humanitarian operations in flood-affected contexts.

Abstract

Post-earthquake disaster response commonly prioritizes casualties, structural damage, accessibility, and other visible impacts, while earthquake-triggered ground failure may receive less operational attention despite its implications for settlement safety, infrastructure, and recovery. Following the M7.7 Flores earthquake of 15 August 2026, this study examines the potential integration of near-real-time ground failure information into disaster response, focusing on the two principal mechanisms represented in the U.S. Geological Survey (USGS) Ground Failure product: liquefaction and earthquake-triggered landslides. Spatial outputs generated following the earthquake are examined to identify areas where ground-failure susceptibility may warrant prioritized attention and field verification. Rather than treating probabilistic model outputs as confirmation of ground failure at specific locations, the study proposes their use as an initial screening layer within a tiered post-earthquake framework. This framework links near-real-time geospatial hazard information with spatial prioritization, targeted field verification, settlement and infrastructure screening, and decisions concerning further geotechnical investigation. The analysis emphasizes that visible structural damage alone may not adequately represent post-earthquake ground conditions; apparently limited surface damage may coexist with underlying instability requiring assessment before repair, reconstruction, or continued occupation. The Flores earthquake illustrates how rapidly available ground failure information can bridge the critical interval between earthquake occurrence and comprehensive field investigation. Integrating such information into disaster response could strengthen risk-informed decision-making and reduce the likelihood that potentially unstable ground conditions are overlooked during recovery.
