The recent paper by Prof. Dr. Tuncay Taymaz on the 29 July 2025 Mw 8.8 Kamchatka (Russia) Earthquake–Tsunami–Volcanic Processes has been published in SCIENCE, one of the world’s most prestigious scientific journals.

Prof.Dr. Tuncay Taymaz, a faculty member of the Istanbul Technical University at the Disaster Management Institute and the Department of Geophysical Engineering of the Faculty of Mines, has conducted an internationally collaborative and competitive multidisciplinary joint research study on the mega subduction zone earthquake that occurred on 29 July 2025 off the Kamchatka Peninsula coast in Russia. The tedious communal effort was conducted along with contributions of our colleagues from China 🇨🇳 USA 🇺🇲 and Türkiye 🇹🇷 by Tuncay Taymaz at Istanbul Technical University.

The 29 July 2025 Mw 8.8 Kamchatka (Russia) earthquake ranks the 6th largest earthquake ever recorded and documented event worldwide using modern geophysical methods and advanced seismological observations during the instrumental era, and has drawn significant international scientific attention due to its global scientific and societal implications. This recent study presents comprehensive findings in the fields of Earthquake Source Seismology, Tsunami Generation, Volcanic Processes and their associated impacts, offering valuable scientific insights into Earthquake Dynamics, Tsunami Hazards, Volcanic Activity, and Natural Disaster Risk Mitigation. The research article presenting these crucial findings has been published in SCIENCE, widely regarded as one of the world’s most prestigious scientific journals.

We congratulate our distinguished faculty member, Prof.Dr. Tuncay Taymaz, for this remarkable achievement, which makes a significant contribution to the international visibility, academic reputation and global recognition of Istanbul Technical University.

ARTICLE TITLE — Simple Unilateral Rupture of the Great Mw 8.8 2025 Kamchatka Earthquake

AUTHORS — Chengli Liu, Yefei Bai, Thorne Lay, Ping He, Yangmao Wen, Xiong Xiong, Tuncay Taymaz

ABSTRACT — On 29 July 2025, a magnitude (Mw) 8.8 great earthquake ruptured along offshore southern Kamchatka, with the aftershock region overlapping that of a 1952 Mw 8.8 to 9.0 event. Like 1952, the 2025 event nucleated at the northeastern end of the rupture, preceded by intense foreshock activity. Joint inversion of teleseismic and InSAR (Interferometric Synthetic Aperture Radar) data for the space-time slip distribution, with validation by means of forward modeling of deep-water tsunami recordings, revealed a southwestward elongated large-slip patch on the curved plate boundary. A slip of up to 14 meters was located offshore southern Kamchatka and Paramushir Island. The 1952 earthquake generated stronger tsunami signals in Hawaii, indicating a different slip distribution. Peak slip in 2025 exceeded the maximum slip deficit accumulated since 1952. Observations of volcanic eruptions after multiple great earthquakes in Kamchatka provide compelling evidence of earthquake volcano interactions.

EDITOR'S SUMMARY — In late July 2025, a magnitude 8.8 earthquake struck off the Kamchatka Peninsula coast in Russia, sparking a trans-Pacific tsunami and triggering volcanic activity in the region. The event highlighted how the recurrence of great earthquakes may not follow regular patterns. Liu et al. combined teleseismic and satellite data with deep-water tsunami recordings to estimate the slip history for the 2025 event. Peak slip was greater than for the similarly located 1952 earthquake despite generating a weaker tsunami. Variable recurrence and slip distributions in this region suggest complex strain release patterns that may heighten seismic risk. — Angela Hessler

The study is partly funded and conducted at Istanbul Technical University (ITU), Disaster Management Institute through the ITU-Research Fund (İTÜ-BAP).
