RAPID: Illapel Earthquake and Tsunami - Environmental Impacts on the North Central Chile Coast

2015年9月16日，智利中北部海岸发生8.3级地震和海啸。这一快速反应项目通过收集易腐烂的实物数据记录了这一事件的地貌影响，这些数据由于震后重建和沉积后变化而迅速丢失。该项目能够将2015年伊拉佩尔事件与之前国家科学基金会资助的智利中北部实地考察期间发现的古地震和海啸进行比较。迅速派出的调查小组将从现有和新的研究地点收集伊拉佩尔地震和海啸的数据。现场、实验室和模型研究将：(1)评估同震和震后地面水平变化；(2)调查海啸的沉积沉积和地貌影响；以及(3)将2015年海啸的模型模拟与预备测量和测量数据进行比较。尽管智利中北部地区地震和海啸频繁，但很少有研究针对历史和史前事件的地质影响。地震和海啸的地质记录可以扩大可供研究的事件范围，从而提高对俯冲带灾害的了解。2015年伊拉佩尔地震和海啸提供了一个宝贵的机会，可以用来研究该区域同震陆地水平变化和海啸证据的性质。该项目通过以下方式促进预期的社会成果：妇女全面参与STEM，方法是支持早期职业生涯的女性PI和她的女性合作者；通过更好地了解智利的海啸危害，改善社会个人的福祉；通过博士后研究人员和学生培训，发展具有全球竞争力的多样化的STEM工作队伍；增加学术界和政府研究人员之间的伙伴关系，以及开展强有力的国际合作。地球科学司、地球深部加工科和国际科学和工程学办公室支持该项目。

On September 16, 2015 a Mw8.3 earthquake and accompanying tsunami struck the coast of north-central Chile. This rapid response project documents the geomorphic impacts of the event by collecting perishable physical data, which is being rapidly lost due to post-earthquake reconstruction and post-depositional change. The project enables comparison of the 2015 Illapel event with paleoearthquakes and tsunamis discovered during previous NSF-funded fieldwork in north-central Chile. Rapidly dispatched survey teams will collect data from the Illapel earthquake and tsunami from existing and new study sites. The field, laboratory, and modeling research will: (1) assess co-seismic and post-seismic land-level change; (2) investigate sedimentary deposits and geomorphic impacts of the tsunami; and (3) compare model simulations of the 2015 tsunami to run-up measurements and surveying data.Despite the frequency of earthquakes and tsunamis in north-central Chile, very few studies have been directed at the geologic impacts of historical and prehistoric events. Geologic records of earthquakes and tsunamis can expand the range of events available for study, thereby improving the understanding of subduction zone hazards. The 2015 Illapel earthquake and tsunami provide an invaluable opportunity to examine the nature of co-seismic land-level change and tsunami evidence in this region. The project advances desired societal outcomes through full participation of women in STEM through support of an early career female PI and her female collaborators, improved well-being of individuals in society through a better understanding of tsunami hazards in Chile, development of a diverse, globally competitive STEM workforce through post-doctoral researcher and student training and increased partnerships between academia and government researchers as well as a strong international collaboration. The Earth Sciences Division Deep Earth Processes Section and the Office of International Science and Engineering support the project.
