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里氏8.3级地震和海啸。这个快速反应项目通过收集易腐烂的物理数据来记录地震对地貌的影响，这些数据由于震后重建和沉积后的变化而迅速丢失。该项目可以将2015年的Illapel地震与之前在智利中北部由nsf资助的实地考察中发现的古地震和海啸进行比较。迅速派遣的调查小组将从现有和新的研究地点收集有关Illapel地震和海啸的数据。实地、实验室和模型研究将：(1)评估同震和震后陆面变化；(2)调查海啸的沉积和地貌影响；(3)将2015年海啸的模型模拟与上升测量和调查数据进行比较。尽管智利中北部频繁发生地震和海啸，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，从而提高对俯冲带危害的认识。2015年伊拉佩尔地震和海啸为研究该地区同震陆地水平变化和海啸证据的性质提供了宝贵的机会。该项目通过支持早期职业女性PI及其女性合作者充分参与STEM，通过更好地了解智利的海啸灾害，改善社会中个人的福祉，发展多样化的，通过博士后研究人员和学生培训，加强学术界和政府研究人员之间的伙伴关系以及强有力的国际合作，培养具有全球竞争力的STEM劳动力。地球科学司深部地球过程科和国际科学与工程办公室支持这个项目。

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.
