Research progress and trend analysis of geological disaster chain based on bibliometrics

[Objective/Significance]This study analyzed 784 publications from 1989 to 2024 in the Web of Science Core Collection database, employing bibliometric methods combined with temporal analysis, keyword evolution, and network analysis. [Analysis/Discussion/Progress]The research development exhibited three distinct?phases: initial?(1989-2000), developmental (2001-2012), and rapid growth (2013-2024). China dominated the?field with 449 publications, with the Chinese Academy?of Sciences leading?institutional productivity (111 papers). The analysis revealed that Natural Hazards (TC=2517), Landslides (h-index=24), and Engineering Geology formed the most influential journal cluster. Research?themes evolved from single-hazard investigations to multi-hazard coupling analysis, while?GIS and remote sensing?technologies significantly enhanced the spatiotemporal scale and precision?of studies. This study?introduces?several?innovative?approaches: a four-dimensional analytical?framework integrating publication volume, research?institutions, journal impact, and research themes; a?novel?coupling?analysis between major?disaster events and research hotspots; and a?systematic?examination?of the relationship?between paradigm shifts and technological advancement. [Conclusion/Prospect]The findings demonstrate that major geological disasters directly drive research trends, and technological innovation?continues?to reshape?research?methodologies. The?established quantitative evaluation?system provides?valuable insights for academic direction?and international collaboration?in geological?disaster chain research.
