Exploring the Evolution of Seismic Hazard and Risk Assessment Research: A Bibliometric Analysis

A bibliometric analysis spanning from 2002 to 2022 examines the landscape of seismic hazard and risk assessment research, critical for disaster preparedness in earthquake-prone regions. The study uncovers a substantial increase in related studies, notably surging around 2006. Leading contributors hail from China, the United States, Italy, and the United Kingdom, underlining the global significance of the subject. Common terms in scholarly articles include "seismic hazard", "seismic risk", "earthquake", "vulnerability", "GIS" (Geographic Information System), and "liquefaction". While seismic hazards remain the primary focus, a growing interest in risk assessment, particularly for induced phenomena like landslides and liquefaction, is noted. Researchers predominantly assess vulnerability across various structural elements, reflecting a holistic approach to understanding and mitigating the impact of earthquakes on infrastructure and communities. In summary, the bibliometric analysis provides a comprehensive overview of seismic hazard and risk assessment research, highlighting field growth, key research areas, and an increasing focus on risk assessment in response to natural phenomena. The findings offer valuable insights for both academics and practitioners invested in the field's future development.
