Abstract On January 1, 2024, a devastating M 7.6 earthquake struck the Noto Peninsula, Ishikawa Prefecture, Japan, resulting in significant casualties and property damage. Utilizing information from first six days after earthquake, this article analyzes seismic source characteristics, disaster situation, emergency response of earthquake. The results show: 1) rupture was thrust type, with aftershock distribution showing north-east-oriented belt-like feature 150 km. 2) Global Navigation Satellite System (GNSS) Interferometric synthetic aperture radar (InSAR), observations detected westward to north-westward co-seismic displacement near epicenter, maximum horizontal reaching 1.2 m vertical uplift 4 m. A two-segment fault inversion model fits observational data well. 3) Near large Peak Ground Velocity (PGV) Acceleration (PGA) were observed, maxima 145 cm/s 2681 gal, respectively, intensity reached highest level 7 on Japanese (Japan Meteorological Agency, JMA) standard, which is higher than 10 United States Geological Survey (USGS) Modified Mercalli Intensity (MMI) standard. 4) observation very rare multiple strong pulse-like ground motion (PLGM) waveform poses topic worthy research field engineering. 5) As 7, had left 128 deaths 560 injuries 1305 buildings completely or partially destroyed, triggered chain disasters including tsunamis, fires, slope failures, road Finally, paper summarizes rescue, dissemination, other management measures taken This work provides reference case for carrying out effective responses, offers lessons handling similar events future.

Earthquake-induced landslides cause extensive harm, necessitating accurate predictions for effective risk management. To tackle the dual challenges posed by inadequate model accuracy and absence of frequency-derived landslide intensity as critical information, this paper presents a robust modelling method that generates high-resolution hazard map assessment. Firstly, Frequency Ratio (FR) is employed to quantitatively explore correlation between geo-environmental factors occurrences, enabling exclusion less significant factors. Subsequently, these FR values are integrated into Light Gradient Boosting Machine (LightGBM) model, resulting in composite FR-LightGBM. test proposed data from areas affected Luding earthquake based on seismic following 2022 Ms 6.8 Sichuan, China, examined. Model validation, using area under curve (AUC) receiver operating characteristic curve, highlighted superior predictive FR-LightGBM marking 3.5 % improvement AUC value compared both Convolutional Neural Network (CNN) Logistic Regression (LR) models. The results have identified high-risk along Dadu riverside Xianshuihe fault zone correspond well with actual distribution. Overall, practical applicability significantly enhanced its capacity prioritize lithology, faults, aspect crucial Additionally, an extended inventory established high spatial resolution (2 m) satellite imagery Chinese Gaofen series, approach delivered (12.5 across area, contributing relevant studies
