RAPID: Chilean Earthquake Rupture Survey

在智利发生8.8级灾难性地震之后，迫切需要记录余震并获取短期数据，以帮助评估该地区和其他地方的短期（即时）和长期地震风险。目前迫切需要可靠的沿断裂带应变积累和孕震释放模型，以及改进的太平洋盆地海啸模型。美国的团队已经在陆地上，另一个团队正准备在近海部署一套海底地震仪。2月27日的主震使秘鲁-智利与南美洲接壤的一个300公里长的俯冲带破裂，导致地面位移高达7米。对主要破裂带的海上部分进行水深测量，并部署了四个高灵敏度的压力表来记录垂直运动，这将补充记录地表影响和可能的地震危险（如海啸）的努力。这项研究的主要广泛影响是其非常高和直接的社会相关性。

In the aftermath of the catastrophic M8.8 earthquake in Chile there is an urgent need to record aftershocks and capture ephemeral data that will help to assess both short term (immediate) and long term earthquake risk in the region and elsewhere. Reliable models of strain accumulation and seismogenic release along the fault zone, and improved tsunami models for the Pacific basin, are urgently needed. U.S. teams are already on the ground onshore, and another team is preparing to deploy a suite of ocean bottom seismometers offshore. The February 27th mainshock ruptured a 300 km long segment of the Peru-Chile subduction zone that borders South America, causing ground displacements of as much as 7 meters. This bathymetric survey of the offshore portion of the main rupture zone and the deployment of four highly sensitive pressure gauges to record vertical motions will complement efforts to document the surface effects and possible earthquake hazards, such as tsunamis. The principal broader impact of this study is its very high and immediate societal relevance.
