This International Research Experience for Students (IRES) contributes to the formation of the next generation of research talent, thereby enhancing U.S. leadership in research and strengthening economic competitiveness. It focuses on mapping and quantifying the seismic hazard in rural communities in Costa Rica in the vicinity of the Guanacaste Volcanic Arc. Over three years, fifteen U.S. underrepresented minority undergraduate and graduate students from Historically Black Colleges and Universities and minority-serving institutions in the state of Georgia will participate in a four-week research experience that is enriched by partnering with the University of Costa Rica, the Comision Nacional de Emergencias, and Observatorio Sismológico y Vulcanológico Arenal-Miravalles. The project creates unique linkages to these Costa Rican organizations that assist in training, educating, and professionally developing the participating students. Students' research findings will impact local communities and organizations by providing them with data for advocacy to garner resources for earthquake readiness. Intellectual products created by IRES participating students will provide essential benefits to society, bringing the attention of government agencies and local organizations. This experience will offer student cohorts the knowledge, motivation, and inspiration to pursue internationally-focused science careers to solve US-national and global challenges. More importantly, this IRES program is built intentionally to deliberately contribute to making the geosciences a diverse, equitable, and inclusive discipline and produce future leaders and mentors for subsequent students in STEM research and education.This IRES site project aims to have students process Interferometric Synthetic Aperture Radar data (InSAR) and collect high-resolution Global Navigational Satellite Systems (GNSS) data in the vicinity of the Guanacaste Volcanic Arc in Costa Rica. By processing the data, participating students will define the boundaries of the active seismogenic boundary and its velocity vector. Using these results, students will (1) determine the main zones of deformation, (2) identify potential seismogenic zones, and (3) produce an assessment of seismic hazards. Our high-resolution approach could offer a rapid identification method for other potential seismic zones. If successful, our findings will be generalizable for focused research in active tectonic zones, including the Western United States.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这种国际研究经验的学生（IRES）有助于下一代研究人才的形成，从而提高美国在研究和加强经济竞争力的领导地位。它的重点是绘制和量化瓜纳卡斯特火山弧附近哥斯达黎加农村社区的地震危险。在三年内，15名来自历史上黑人学院和大学以及格鲁吉亚州少数民族服务机构的美国代表性不足的少数民族本科生和研究生将参加为期四周的研究体验，通过与哥斯达黎加大学，国家紧急情况委员会和天文台Sismológico y Vulcanológico Arenal-Miravalles合作而丰富。该项目与这些哥斯达黎加组织建立了独特的联系，这些组织协助培训，教育和专业发展参与的学生。学生们的研究成果将影响当地社区和组织，为他们提供宣传数据，为地震准备工作筹集资源。IRES参与学生创造的知识产品将为社会提供重要的利益，引起政府机构和地方组织的关注。这种经验将为学生提供知识，动机和灵感，以追求国际化的科学事业，以解决美国国家和全球的挑战。更重要的是，这个IRES计划是故意建立的，故意有助于使地球科学成为一个多样化，公平，该IRES站点项目旨在让学生处理干涉合成孔径雷达数据（干涉合成孔径雷达）并收集高分辨率全球导航卫星系统（GNSS）数据在附近的瓜纳卡斯特火山弧在哥斯达黎加。通过处理数据，参与学生将确定活跃孕震边界的边界及其速度矢量。利用这些结果，学生将（1）确定主要变形区，（2）识别潜在的地震孕育区，（3）对地震危险性进行评估。我们的高分辨率方法可以为其他潜在的地震带提供快速识别方法。如果成功的话，我们的发现将被推广到活跃构造带的重点研究中，包括美国西部。这个奖项反映了NSF的法定使命，并被认为是值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估的支持。
