Abstract: Earthquake-induced landslides represent a critical global challenge, contributing significantly to secondary hazards associated with seismic activity. This study presents a comprehensive bibliometric analysis of earthquake-induced landslides research to highlight dominant trends, research interests, and future directions. Literature published between 2000 and 2024 was retrieved from the Web of Science (WOS) database using search terms “earthquake-induced landslides” and “coseismic landslides,” yielding 1,090 relevant publications. Bibliometric analysis was conducted using VOSviewer, focusing on co-authorship networks, citations, keyword co-occurrence, and publication sources. The results indicate that the keywords ‘landslides and earthquakes’ exhibited the highest frequency and total link strength, with strong associations to ‘earthquake chain hazards’ and ‘hazard and risk assessment’. Landslides emerged as the leading journal with 85 publications and ranked second in total citations. Chong Xu was identified as the most prolific author, contributing 70 articles, followed by Qiang Xu and Xuanmei Fan, both with high citation impacts. Institutional analysis highlighted Chengdu University of Technology as the most influential organization with 35 articles. Overall, bibliometric trends reveal a sustained emphasis on susceptibility, hazard, and risk assessment of earthquake-induced landslides and mitigation strategies. Future research is expected to expand rapidly, underscoring the importance of interdisciplinary frameworks and international collaboration to enhance resilience to earthquake-induced geohazards.

Keywords: Earthquake-induced landslides, coseismic landslides, Web of Science, VOSviewer, bibliometric trends

Abstrak: Tanah runtuh akibat gempa bumi merupakan cabaran global yang signifikan dan menyumbang secara langsung kepada pembentukan bahaya sekunder yang berkaitan dengan aktiviti seismik. Kajian ini membentangkan analisis bibliometrik yang komprehensif terhadap penyelidikan tanah runtuh akibat gempa bumi bagi mengenal pasti corak perkembangan, kecenderungan penyelidikan, serta hala tuju masa hadapan dalam bidang ini. Literatur yang diterbitkan antara tahun 2000 hingga 2024 telah diperoleh daripada pangkalan data Web of Science (WOS) menggunakan kata kunci earthquake-induced landslides dan coseismic landslides, menghasilkan sebanyak 1,090 penerbitan yang relevan. Analisis bibliometrik dilaksanakan menggunakan perisian VOSviewer dengan menumpukan kepada rangkaian kerjasama penulisan, analisis sitasi, kewujudan bersama kata kunci, dan sumber penerbitan. Hasil kajian menunjukkan bahawa kata kunci “landslides and earthquakes” mencatatkan kekerapan dan kekuatan hubungan tertinggi, serta mempunyai kaitan rapat dengan “earthquake chain hazards” dan “hazard and risk assessment”. Jurnal Landslides dikenal pasti sebagai jurnal paling dominan dari segi bilangan penerbitan dan jumlah sitasi. Chong Xu muncul sebagai penyumbang paling prolifik, diikuti oleh Qiang Xu dan Xuanmei Fan yang turut menunjukkan impak sitasi yang tinggi. Analisis institusi menonjolkan Chengdu University of Technology sebagai institusi paling berpengaruh dalam bidang ini. Secara keseluruhannya, dapatan bibliometrik memperlihatkan penekanan berterusan terhadap penilaian kerentanan, bahaya dan risiko tanah runtuh akibat gempa bumi, serta pembangunan strategi mitigasi. Penyelidikan masa hadapan dijangka berkembang secara pesat, menekankan keperluan kerangka antara disiplin dan kerjasama antarabangsa bagi meningkatkan daya tahan terhadap bahaya geologi berkaitan gempa bumi.
