二 |     A powerful Monday morning earthquake has killed at least 111 and injured 87 in the west part of Colombia.         Colombia's President Abelardo de la Espriella, who came to office just three days before the earthquake, declared a state of emergency to expedite funding for the quake recovery with a plan to visit the disaster zone.    "I am at the forefront of the situation. It pains me deeply what the families and affected regions are going through," he posted on X.    According to information provided by Colombian officials by mid-afternoon, the destruction included 1,575 damaged homes, 37 homes completely destroyed, 61 collapsed buildings, scores of damaged centers of health, education and community, as well as 18 damaged roads and six airports.    Airports in Pereira, Manizales, Quibdo, Armenia, Cartago and Buenaventura suffered structural damage, and their flight operations were suspended, according to Colombia's Civil Aviation Authority.    The tremor was felt in Colombia's capital Bogota, which is about 400 kilometers from the epicenter, setting off alarms that prompted people to evacuate many buildings as a precaution.    "At this time there are no reports of injuries or structural damage, only some cracks in buildings," Bogota Mayor Carlos Galan posted on X.    The earthquake damaged the region's major cities including Pereira, Quibdo, Manizales and Cali.    Nubia Carolina Cordoba-Curi, governor of the Choco region, posted on X on Monday morning that "in the capital Quibdo there are injuries and severe damage to buildings".    She posted an update at 2 pm that 12 people were confirmed dead and 84 injured in Choco.    Other local authorities reported at least 40 deaths in the Risaralda region and 27 deaths in the Valle del Cauca region.    Rescue efforts to save people buried under the debris is ongoing.    According to the Colombia Geological Service, the earthquake epicenter was in San Jose del Palmar, Choco. It had a magnitude of 7.4 and a depth of approximately 103 km, making it the strongest earthquake recorded in Colombia in the last decade.    The earthquake was felt by neighboring countries Venezuela, Ecuador and Panama. It was followed by several aftershocks with magnitudes between 2.8 and 4.8, according to the agency.    The agency said that it's common for this region to experience earthquakes of considerable magnitudes due to activities associated with the subduction of the Nazca Plate beneath the South American Plate.    Near the end of June, Venezuela was struck by two earthquakes — with magnitudes of 7.2 and 7.5 — that were only 39 seconds apart. More than 6,000 people were killed, and tens of thousands of people remain missing under the debris.                    。中央气象台预计，未来3天，黄淮西南部、江淮、江汉、江南北部和东部仍有大到暴雨，部分地区有大暴雨。当前正值秋收作物产量形成关键期，持续降水对农业生产带来哪些影响？  中央气象台首席气象服务专家宋迎波介绍，受“白海豚”影响，8月8日以来，浙江、上海、江苏中南部、安徽大部、湖北西北部、河南等地出现较强风雨天气。

三 | 部分低洼农田出现积水，导致作物根系缺氧，易引发早衰，对秋收作物正常生长造成不利影响。同时，大风导致玉米等高秆作物倒伏，经济林果出现折枝落果，温室大棚和水产养殖设施也不同程度受损。  “持续降雨容易使低洼农田发生渍涝灾害，不利于正处在开花期的夏玉米和一季稻授粉，并可能导致棉花落铃、烂铃增多。伴随降水而来的大风，容易引发植株倒伏，同时可能损毁温室大棚、造成雨水倒灌，直接影响果蔬生产。

四 | ”宋迎波说，高温高湿环境也容易使农作物病虫害蔓延。  如何科学应对持续降雨形成的农业气象灾害？宋迎波建议，降水偏多地区及时疏通沟渠，确保排水畅通；雨后尽快排涝散墒，降低土壤湿度，恢复土壤通气性，减少根系缺氧时间；受强降水冲刷出现脱肥的地块应适时追施速效肥，促进作物恢复生长。涝渍过后，容易出现病虫害，需抓住晴好天气喷药防治。  宋迎波同时建议，对倒伏但茎秆未折断的玉米，最好在倒伏后三至四天内扶正培土；棉田应及时整枝打杈，改善田间通风透光条件，减少花铃脱落；果园方面，及时清理落果和断枝。此外，各地要科学蓄水，为秋收作物后期用水做好储备。  国家气象中心相关负责人表示，面对复杂的天气形势，国家气象中心将聚焦秋粮生产关键时段，重点围绕秋粮生长发育、产量形成及秋收秋种全链条开展精细化服务。9月将全面启动秋收秋种气象服务，推动定制化气象信息接入全国农机作业指挥平台，靶向发布农业气象灾害风险预警。同时，加强与农业农村、交通运输、水利、粮食物资等部门会商研判，健全信息共享与联防联控机制，全力保障秋粮稳产增收。
