Lithuania
Lithuania位于Europe，地震风险分类为Low。该国地震史上共记录了0次地震。 该国人口为2894886，国土面积为65300平方公里，地震活动可能对基础设施和公共安全产生重大影响。
地震概况
Lithuania shares the tectonic character of the wider Baltic region, sitting on the southwestern part of the East European Platform. The country's Precambrian crystalline basement is ancient and cold, with no active [[fault]] systems recognized at the surface. Natural earthquake activity within Lithuanian territory is minimal: the national and regional seismic networks record only occasional microearthquakes, and felt events are rare. The largest events in the regional catalog that could be felt in Lithuania have been distant earthquakes in the Baltic Sea or in Scandinavia rather than local events. No historically documented earthquake damage has occurred in Lithuania.
From a practical standpoint, Lithuania faces negligible seismic hazard, and no seismic design provisions apply to ordinary buildings. The country's participation in European seismic monitoring networks provides useful data for regional tectonic studies but reveals no concerning local [[seismic-wave|seismic]] source zones.

常见问题解答
Lithuania has a low level of seismic activity. Large earthquakes are infrequent but not impossible. A total of 0 earthquakes have been recorded in Lithuania's seismic history.
Lithuania has had 0 recorded earthquakes. This count includes events of all magnitudes detected by seismic monitoring networks. The actual number of earthquakes may be higher, as smaller events can go undetected.
Lithuania is classified in the "Low" seismic zone, located in Europe. Seismic zones indicate the relative level of earthquake hazard based on historical activity, geological conditions, and proximity to tectonic plate boundaries.
地震时，蹲下、掩护、抓紧。躲到坚固的桌子下面，保护头部和颈部，紧紧抓住直到震动停止。远离窗户和重物。地震后，检查伤情并做好余震准备。
国家地震风险通过多个因素评估：与板块边界的距离、历史地震活动（过去地震的频率和震级）、地质条件、地震带的人口密度以及建筑规范的执行情况。QuakeFYI根据这些因素分配从0（无风险）到4（极高风险）的地震带等级。
地震带是根据地震危险程度划分的地理区域。0级带风险可忽略，1级带风险较低，2级带风险中等，3级带风险较高，4级带风险极高。这些分带由历史地震数据、构造背景和地质条件决定。
环太平洋火山带沿线的国家经历最多的地震。日本、印度尼西亚、智利、菲律宾和伊朗的地震活动始终最为活跃。美国（尤其是阿拉斯加和加利福尼亚）、土耳其和墨西哥也是地震活动最频繁的国家之一。
人口密度会放大地震风险，因为更多的人口和基础设施暴露在潜在的损害之下。人口密集城市中7.0级地震可能造成数千人伤亡，而同样的地震发生在无人区可能不会造成任何伤亡。建筑规范和应急准备可以大大降低人口密集地区的风险。
地震密度衡量地震活动相对于国家国土面积的集中程度，以每1,000平方公里的地震次数表示。高地震密度表示单位面积地震活动频繁，有助于比较不同面积国家之间的地震风险。
