Core Viewpoint - The Ministry of Natural Resources emphasizes the importance of preparedness and response to geological and marine disasters caused by Typhoon "Hagupit," coordinating efforts across key provinces to ensure public safety and property protection [1] Group 1: Emergency Response Measures - The Ministry has conducted consultations and deployed resources to provinces such as Guangdong, Guangxi, Hainan, and Fujian to address the situation [1] - There is a strong emphasis on monitoring, early warning, and information dissemination to ensure timely responses to the typhoon's impact [1] - The Ministry has initiated a red alert for storm surges and waves, activating a level one emergency response for marine disasters and a level four defense response for geological disasters [1] Group 2: Coordination and Collaboration - The Ministry calls for enhanced collaboration with meteorological, water resources, and emergency departments to share information and integrate disaster prevention efforts [1] - A total of 38 experts have been dispatched to support geological and marine disaster prevention efforts in affected provinces [1] - The focus is on high-risk areas, including densely populated regions and critical transportation routes, to ensure thorough inspections and disaster reporting [1]

Core Insights - The "Hainan Province Marine Disaster Multi-dimensional Monitoring and Intelligent Forecasting High-Quality Data Set" was officially recognized at the 2025 China International Big Data Industry Expo, highlighting its significance in marine disaster management [1][2] Group 1: Data Set Features - The data set focuses on various marine disasters such as typhoons, storm surges, red tides, waves, and rip currents, enhancing the accuracy, timeliness, and precision of marine disaster forecasts [1] - It integrates GPU-CPU heterogeneous computing, deep learning, and AI models to create a forecasting model covering wind, waves, currents, and storm surges along the Hainan coastline, resulting in approximately 9.6TB of high-quality data [1] Group 2: Technological Breakthroughs - Three significant breakthroughs were achieved: 1. Development of intelligent correction and fine scene interpretation technology, greatly improving the accuracy and timeliness of marine environmental forecast products [1] 2. Enhancement of risk warning and assessment systems for ecological disasters like red tides through a physical-chemical-biological coupling model [1] 3. Implementation of machine vision and dynamic sampling training for intelligent identification of waves and rip currents, improving warning timeliness by approximately 30% [1] Group 3: Data Management and Application - A comprehensive data management mechanism covering "real-time perception—precise forecasting—ecological protection—intelligent control" has been established, currently applied in over 10 marine disaster prevention and control business scenarios [2] - The project promotes efficient circulation and business application of marine data resources through multi-regional collaboration and data sharing mechanisms, providing "Hainan wisdom" and a "data model" for marine disaster prevention and mitigation [2] - This data set is a result of the "Hainan Province Marine Disaster Comprehensive Prevention and Control Capacity Building Project," which is set to be completed and operational by July 2025 [2]

Core Viewpoint - A strong earthquake occurred off the eastern coast of the Kamchatka Peninsula, triggering a tsunami warning, but it is not expected to cause significant damage to China's coastal areas [1] Group 1: Tsunami Warning Details - The earthquake occurred on July 30, 2025, at 7:24 AM Beijing time, prompting the issuance of a yellow tsunami warning by the National Natural Resources Department [1] - The yellow warning indicates a tsunami wave height of 0.3 to 1 meter, with an expected wave height of 0.3 meters along China's mainland coast, posing no disaster risk [1] - Monitoring stations reported tsunami waves of 1 meter at Midway Atoll, 0.9 meters at buoy 21416, and 0.4 meters at Japan's Ofunato station, with potential impacts on Taiwan's eastern coastal areas [1] Group 2: Tsunami Risk Mitigation - The natural island chain and reefs in the Pacific effectively dissipate tsunami energy, significantly reducing the impact on China's coastal regions [2] - The East China Sea and Yellow Sea, characterized by broad continental shelf areas, further diminish tsunami wave energy due to shallow water topography [2] - Historical data indicates that nearshore earthquakes in China are generally of lower magnitude, with rare occurrences of magnitude 8 or higher, which reduces tsunami risk [2]
