                  習近平總書記在視察唐山時的重要講話:我國是世界上自然災害最為嚴重的國家之一,災害種類多,分布地域廣,發生頻率高,造成損失重,這是一個基本國情。新中國成立以來特別是改革開放以來,我們不斷探索,確立了以防為主、防抗救相結合的工作方針,國家綜合防災減災救災能力得到全面提升。要總結經驗,進一步增強憂患意識、責任意識,堅持以防為主、防抗救相結合,堅持常態減災和非常態救災相統一,努力實現從注重災后救助向注重災前預防轉變,從應對單一災種向綜合減災轉變,從減少災害損失向減輕災害風險轉變,全面提升全社會抵御自然災害的綜合防范能力。防災減災救災事關人民生命財產安全,事關社會和諧穩定,是衡量執政黨領導力、檢驗政府執行力、評判國家動員力、體現民族凝聚力的一個重要方面。當前和今后一個時期,要著力從加強組織領導、健全體制、完善法律法規、推進重大防災減災工程建設、加強災害監測預警和風險防范能力建設、提高城市建筑和基礎設施抗災能力、提高農村住房設防水平和抗災能力、加大災害管理培訓力度、建立防災減災救災宣傳教育長效機制、引導社會力量有序參與等方面進行努力。

                  緬懷美籍華人科學家郭宗汾先生

                  2022年4月29日,美籍華人科學家、國際著名地球物理學家、哥倫比亞大學教授、原奧爾德里奇應用地球物理實驗室主任,郭宗汾先生在美國紐約去世,享年100歲。

                  上世紀八十年代,由中國地震局地球物理研究所顧功敘教授和美國哥倫比亞大學郭宗汾John T.Kuo教授倡導的中美合作項目局部重力場變化與地震發生的關系立項。其研究宗旨是在京津唐張地區開展時變重力觀測,探索與地震發生有關的重力變化現象和機理,該工作為后來我國建立大陸地震時變重力監測網絡系統奠定了研究基礎。

                  1976年唐山大地震后,時任美國哥倫比亞大學拉蒙特-多爾蒂地質觀象臺的郭宗汾教授心系祖國,他多方籌集資金并帶著當時最先進的新型高精度重力儀器和成套設備來到我國華北地區,建立了8個具有連續觀測能力的重力臺站和流動觀重力重復觀測網,通過二十多年的研究獲得了京津唐張地區與地震發生有關的重力變化過程具有清晰的、一致的圖像。該項目成果也為研究局部重力場變化與地震之間關系的提供了寶貴的地球物理學依據。

                  Cherish the memory of Professor John T. Kuo

                  April 29, 2022, Professor John T. Kuo, a Chinese American scientist, a world-famous geophysicist, a great professor at the Columbia University, and the former director of the Aldridge Laboratory of Applied Geophysics, passed away in New York, USA, at the age of 100.

                  We lost Professor John T. Kuo only days ago, but we have missed him for a long time. In the 1980s, the Sino-US cooperative project of "Relationship between local gravity field variation and earthquakes" was initiated by Professor John T. Kuo and Professor Gongxu Gu from Institute of Geophysics, China Earthquake Administration. The purpose of the project is to carry out time-varying gravity observations in Beijing-Tianjin-Tangshan-Zhangjiakou area, and to explore the mechanism of gravity variations related to the occurrence of earthquakes. This project laid the research foundations for the establishment of continental earthquake time-varying gravity monitoring network system in China.

                  After the Tangshan earthquake in 1976, Professor John T. Kuo, who was working at the Lamont–Doherty Earth Observatory at the Columbia University, had shown his love towards the motherland. He raised funds from various sources and bought lots of most advanced new high-precision gravity instruments in the world at that time for China, establishing 8 gravity stations with continuous monitoring capabilities and a mobile gravity repeated observation network system in the North China. He obtained clear and consistent images showing the gravity variation is related to the earthquake occurrence in Beijing-Tianjin-Tangshan-Zhangjiakou area, based on more than 20 years of research. The results of this project also provide valuable geophysical bases for studying the relationship between local gravity field variation and earthquakes.
