在重力、地磁等地球物理场观测工作中，白玛桑布要开展多源观测数据预处理，完成数据格式转换、质 量检查、时序校正等一系列标准化处理。针对仪器噪声、电磁干扰、气象变化等非构造性干扰因素，他 要综合运用滤波、异常值检测与降噪等技术方法，精准过滤各类噪声干扰，提升数据信噪比与可靠性。 通常要用4个小时，才能完成上午的数据填报与分析处理工作。 在拉萨中心站，和白玛桑布一样的地震监测员共有14名，他们都亲切地称地震监测工作是在为地球"把 脉"。"我们通过设备监测地球脉动就是在给地球做'心电图'，每地震一次相当于地球生了一次'病'，分 析记录地震事件就是在给地球看病、问诊、写'病历'。"白玛桑布以人类看病为例解释说，大医院接触 到的病例多，治疗疑难杂症的方法更多也更好，"我们对地震相关数据进行连续记录，就是希望能从中 找到一些周期性的规律，为地震预报提供技术支撑"。 2025年1月7日，西藏定日县发生6.8级地震。白玛桑布当天值班，他第一时间投入到震后应急处置工作 中。他告诉记者，地震发生当日18时许，他与同事便紧急赶赴震区。在震中区域，他们连续奋战，平均 每天工作近10个小时，仅用3天时间，就成功架设了10个应急流动地震监 ...

在被称为"地球第三极"的青藏高原上，我国已开展地震监测超过60年。 地域广是西藏地震监测的一大困难。欧阳兆国是黑龙江省地震局的援藏干部，已在西藏自治区地震局工 作近1年。他告诉记者，西藏自治区地震局下辖拉萨、林芝、阿里3个地震监测中心站，而拉萨中心站的 辖区范围包括拉萨、日喀则、山南、那曲4个地市，辖区面积达62万平方公里，"约占整个西藏面积的 1/2"。 西藏自治区地处青藏高原主体区域，平均海拔超4000米，是我国平均海拔最高的省级行政区。这里高寒 缺氧、气候恶劣，地质构造运动极其活跃。1956年，拉萨地球物理观象台（现西藏自治区地震局拉萨地 震监测中心站，以下简称"拉萨中心站"）建成，我国开始在这片"世界最年轻的高原"上监测地震。 建站69年来，一代代地震监测工作者在拉萨中心站坚守，保障着我国地震观测数据的连续性和完整性， 为地震监测预警提供了重要支撑。春节将至，中青报·中青网记者来到拉萨中心站，实地探访坚守在这 里的地震监测工作者。 为地球"把脉" 9时30分许，太阳刚刚从青藏高原的地平线上跃起，冬日的阳光洒在乳白色的布达拉宫东壁上。因为日 光的到来，整个拉萨河谷瞬间暖和了不少。 迎着朝阳，拉萨中心站的 ...

Core Insights - The establishment of the first national strong motion accelerometer calibration device at the China Earthquake Administration's First Monitoring Center is aimed at enhancing the precision of earthquake monitoring [1][4]. Group 1: Strong Motion Accelerometers - Strong motion accelerometers are critical instruments for rapid earthquake intensity assessment and are currently deployed in over 5,000 units across the national seismic monitoring network, with plans to expand to over 20,000 units during the 14th Five-Year Plan [4]. - These devices capture ground vibration signals immediately after an earthquake occurs, providing essential data for determining earthquake intensity, calculating the epicenter, and identifying the time of occurrence [4][9]. Group 2: Calibration Device Features - The newly established calibration device features advanced vibration simulation capabilities and high measurement precision, capable of simulating maximum vibration intensity equivalent to a car accelerating from rest to 216 kilometers per hour in 2 seconds [8]. - It can accurately replicate ground vibrations caused by earthquakes ranging from magnitude 1 to 8, ensuring that calibrated devices can reliably respond to various earthquake intensities [8]. Group 3: Impact on Earthquake Monitoring - The calibration device's measurement error is less than 0.0002 of the earthquake magnitude, significantly below human perception limits, which enhances the scientific analysis and assessment of earthquake damage [8]. - China has built the world's largest and most comprehensive earthquake early warning network based on domestically produced high-precision instruments, which provides critical time for public safety and emergency responses in sectors like high-speed rail and precision manufacturing [9].

Core Viewpoint - The Tancheng-Lujiang Fault Zone is a significant geological feature in East Asia, known for its historical seismic activity and ongoing monitoring efforts to ensure public safety and disaster preparedness [1][4]. Group 1: Monitoring and Measurement - The Tancheng-Lujiang Fault Zone extends over 2400 kilometers, with a history of significant earthquakes, including the 8.5 magnitude earthquake in 1668 [1]. - The Anqiu Earthquake Monitoring Station, established in 1969, plays a crucial role in monitoring the fault zone, utilizing advanced equipment such as superconducting gravimeters and strong motion accelerometers [4][5]. - The station has conducted cross-fault leveling measurements since 1991, with monthly assessments at nine sites and six fixed-point measurements at the fault [4]. Group 2: Earthquake Early Warning - The Anqiu Earthquake Monitoring Station is equipped with a comprehensive earthquake early warning system, capable of issuing alerts within 5-30 seconds after an earthquake occurs [5]. - The national earthquake early warning project, initiated in 2018, has established 15,899 observation stations and three national warning centers, enhancing the monitoring and response capabilities [5]. - The system provides critical information such as the time of occurrence, epicenter location, and magnitude within 1-2 minutes, and generates intensity distribution maps within 2-5 minutes [5]. Group 3: Public Education and Community Engagement - The Anqiu Earthquake Monitoring Station serves as a national disaster prevention and reduction education base, having hosted over 100,000 visitors for educational activities [6]. - The station actively engages with local communities and enterprises to provide services such as fault location assessments and disaster loss evaluations [6]. - Educational initiatives include hands-on experiences for students, such as VR simulations of earthquakes and emergency preparedness training [6]. Group 4: Future Outlook - The ongoing efforts of the monitoring station reflect a commitment to public safety and economic development, with staff dedicated to capturing seismic activity and enhancing community resilience [7].
