AbstractOn February 6, a successive rupture of major faults in the Eastern Anatolian Fault Zone and Cardak-Surgu fault triggered a strong mainshock (Mw 7.7) and a major aftershock (Mw 7.6) in Kahramanmaras. The successive earthquake sequence hit southern provinces in Türkiye and northern regions in Syria, causing severe fatality and economic loss. After the earthquakes, the International Consortium on Geo-disaster Reduction (ICGdR) organized an investigation team, involving specialists from China, Japan and Türkiye, to conduct a primary field reconnaissance on seismic damage of infrastructure and ground failures. The 10-day reconnaissance, including a mini-symposium at the Istanbul Technical University (ITU), was conducted from 25 March to 3 April and specifically focused on fault ruptures, liquefaction, landslide, rockfall and lateral spreading along the major ruptured faults from Antakya in Hatay to Goksun in Kahramanmaras, passing through provinces of Gaziantep, Adıyaman and Malatya. By this reconnaissance, a large amount of original seismic data was collected and a primary understanding was established for further steps on mitigation and reduction of seismic damages and its secondary geohazards.

AbstractThe International Workshop on Seismic Design and Assessment for Resilience, Robustness and Sustainability of Slope Engineering was held on 13–15 January 2023 on line, focusing on the theme of “Seismic resilience of slope engineering and the concept of resilience-based seismic design (RBSD) for geological disaster prevention and control”. In this workshop, a number of keynote and invited lectures provided an international exchange platform for researchers, industrial engineers and students to share their research, engineering practice and exchange novel ideas on seismic resilience for slope engineering in a way of online. At the same time, during this workshop, technical committee of the ICGdR-TC1 also took this opportunity to hold a working meeting on cutting-edge and strategic issues, and released the Shanghai Declaration on slope engineering.

Abstract Background On 15 January 2022, a submarine volcanic eruption occurred at Hunga Tonga. Time-series monitoring from the Geostationary Operational Environmental Satellite (GOES-17) was analysed to estimate the magnitude, location, start time, and duration of the eruption and to measure the evolving characteristics of Hunga Ha’apai Island. Results The eruption starting time was between 04:10 and 04:20 UTC with an eruption intensity that increased drastically and produced a plume that reached a maximum height of about 58 km. The explosive phase lasted 13 h and consisted of multiple steam and tephra explosions with an M 5.8 earthquake. The Airmass RGB, which combines water vapor and infrared imagery from the ABI and was used to monitor the evolution of the volcano, captured a plume of gases from the eruption of Hunga Tonga volcano on 15 January 2022. This type of imagery provides information on the middle and upper levels of the troposphere and distinguishes between high- and mid-level clouds. Conclusion A sonic explosion also occurred, possibly when the volcano collapsed underwater and seawater rushed in, causing a huge displacement of seawater. The Hunga Tonga–Hunga Ha’apai eruption is not over and could worsen in the coming days. Future studies are required to assess the potential effects on stratospheric chemistry and radiation for secondary damage analysis.

Accurate prediction of landslide susceptibility relies on effectively handling absence samples in data-driven models. This study investigates the influence of different absence sampling methods, including buffer control sampling (BCS), controlled target space exteriorization sampling (CTSES), information value (IV), and mini-batch k-medoids (MBKM), on landslide susceptibility mapping in Songyang County, China, using support vector machines and random forest algorithms. Various evaluation metrics are employed to compare the efficacy of these sampling methods for susceptibility zoning. The results demonstrate that CTSES, IV, and MBKM methods exhibit an expansion of the high susceptibility region (maximum susceptibility mean value reaching 0.87) and divergence in the susceptibility index when extreme absence samples are present, with MBKM showing a comparative advantage (lower susceptibility mean value) compared to the IV model. Building on the strengths of different sampling methods, a novel integrative sampling approach that incorporates multiple existing methods is proposed. The integrative sampling can mitigate negative effects caused by extreme absence samples (susceptibility mean value is approximately 0.5 in the same extreme samples and presence-absence ratio) and obtain significantly better prediction results (AUC = 0.92, KC = 0.73, POA = 2.46 in the best model). Additionally, the mean level of susceptibility is heavily influenced by the proportion of absent samples.

To analyze the kinetic characteristics of a debris flow that occurred on 9 April 2000 in Tibet, China, a meshfree numerical method named smoothed particle hydrodynamics (SPH) is introduced, and two-dimensional and three-dimensional models are established in this work. Based on the numerical simulation, the motion process of this debris flow is reproduced, and the kinetic characteristics are analyzed combining with the field investigation data. In the kinetic analysis, the flow velocity, runout distance, deposition, and energy features are discussed. Simulation results show that the debris flow mass undergoes an acceleration stage after failure, then the kinetic energy gradually dissipates due to the friction and collision during debris flow propagation. Finally, the debris flow mass blocks the Yigong river and forms a huge dam and an extensive barrier lake. The peak velocity is calculated to be about 100 m/s, and the runout distance is approximately 8000 m. The simulation results basically match the data measured in field, thus verifying the good performance of the presented SPH model. This approach can predict hazardous areas and estimate the hazard intensity of catastrophic debris flow.
