A | 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. 
。 新华社北京4月28日电（记者高敬）今年一季度，全国环境空气质量和水生态环境质量总体均持续改善。 生态环境部新闻发言人裴晓菲在28日举行的新闻发布会上介绍了这一情况。
B | 他介绍，从环境空气质量状况来看，一季度，全国339个地级及以上城市PM2.5平均浓度为43微克/立方米，同比下降6.5%；空气质量优良天数比例为83.6%，同比上升3.5个百分点；重度及以上污染天数比例为2.4%，同比下降0.9个百分点。 其中，京津冀及周边地区“2+36”城市、汾渭平原13个城市PM2.5平均浓度同比分别下降7.2%和16.7%，优良天数比例同比分别上升10.9和13.1个百分点。但长三角地区31个城市PM2.5平均浓度同比上升12.8%，优良天数比例同比下降4.6个百分点。 从水生态环境质量状况来看，3641个国家地表水考核断面中，水质优良（Ⅰ至Ⅲ类）断面比例为89.9%，同比上升0.8个百分点；劣Ⅴ类断面比例为0.7%，同比上升0.1个百分点。主要污染指标为化学需氧量、高锰酸盐指数和总磷。其中，长江、黄河等主要江河水质优良断面比例为91.5%，同比上升1.2个百分点；劣Ⅴ类断面比例为0.5%，同比上升0.1个百分点。 数据同时显示，监测的201个重点湖库中，水质优良湖库比例82.1%，同比上升1.1个百分点；劣Ⅴ类水质湖库比例4.5%，同比下降0.1个百分点。主要污染指标为总磷、化学需氧量和高锰酸盐指数。
