IRES Track 1: Guatemala Geohazards International Research Experiences for Students-Understanding the Long-term Records of Volcanic, Seismic, and Landslide Hazards

该奖项全部由《2021年美国救援计划法案》（公法117-2）资助。危地马拉地质灾害国际学生研究经验（危地马拉地质灾害IRES）项目的目标是让美国本科生发展进行和交流科学研究的技能，利用数字技术和现代分析实验室设备利用综合领域和实验室研究方法，并通过与危地马拉学生，教授，和工业合作伙伴一起解决关于危地马拉城地堑第四纪地质灾害长期记录的研究问题。危地马拉的板块边界设置使该国面临许多自然灾害，包括来自四个震源地区的地震，中美洲活跃火山弧沿线的火山爆发，以及由于地球变暖而更频繁的热带风暴和飓风而加剧的山体滑坡和洪水。危地马拉地质灾害IRES项目有潜力增加妇女和代表性不足的少数民族从事研究、完成学士学位、继续在地球科学领域攻读研究生课程和从事职业。我们的IRES还为我们的榜样带来了多样性，有六位西班牙裔导师和三位女性教师导师。我们与危地马拉同事、工业采矿地质学家的合作，以及实地考察的国际性质，将为学生提供无与伦比的文化丰富途径，以及全球合作的经验，这对学生未来在日益全球化的劳动力和经济中取得成功将是无价的。危地马拉城（GC）地铁延伸在一个由火山凝灰岩和熔岩流组成的高原上，这些火山流来自与该地区南部和西南部接壤的活火山，包括帕卡亚、富埃戈、阿卡特南戈和阿瓜，以及沿弧线的其他火山中心，尽管实际的火山地层学还不清楚。GC都会区被一个活动断层系统切断，该系统定义了向北走向的危地马拉城地堑。可能受断层控制的陡峭沟壑或峡谷，深深剖析了地形，使其极易发生滑坡。这种地质和构造环境使其成为研究该地区第四纪火山、地震和滑坡灾害相互作用的理想场所。通过工业合作伙伴和新的道路切割，实地访问提供了理想的位置，可以利用高分辨率露头和卫星图像，以及地球化学、岩石学和地质年代学数据，这些数据可用于量化最近和活跃的地质过程，包括火山爆发的顺序、风格和时间，断层和过去地震的运动学和位移历史，以及导致滑坡失败的潜在特性的研究。危地马拉地质灾害IRES学生将有一个前所未有的机会，在与危地马拉学生、导师和专业人士建立国际经验和合作的同时，发展火山碎屑地层学、新构造学和滑坡灾害方面的现场和实验室技能。该奖项反映了美国国家科学基金会的法定使命，并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，被认为值得支持。

This award is funded in whole under the American Rescue Plan Act of 2021 (Public Law 117-2).The goal of this Guatemala Geohazards International Research Experiences for Students (Guatemala Geohazards IRES) project is for U.S. undergraduate students to develop skills in conducting and communicating scientific research, to utilize an integrative field and lab research approach using digital technology and modern analytical lab equipment, and to learn international cooperation by collaborating side-by-side with Guatemalan students, professors, and industrial partners to address research questions on the long-term Quaternary record of geological hazards in the Guatemala City Graben. The plate boundary setting of Guatemala exposes the country to numerous natural hazards including earthquakes from four source areas, volcanic eruptions along the active Central American Volcanic Arc, and landslides and floods that have intensified by more frequent tropical storms and hurricanes in a warming Earth. The Guatemala Geohazards IRES project has the potential of increasing both the number of women and under-represented minorities conducting research, completing a bachelor's degree, and continuing to graduate programs and careers in geosciences. Our IRES also brings diversity to the face of our role models with six Hispanic mentors and three women faculty mentors. Our collaboration with Guatemalan colleagues, industry mining geologists, and the international nature of the fieldwork will provide an unparalleled avenue for cultural enrichment for the students as well as an experience in global cooperation that will be invaluable for a student's future success in an increasingly global workforce and economy. The Guatemala City (GC) Metro sprawls over a high plateau composed of volcanic tuff and lava flows from active volcanoes that border the region to the south and southwest including Pacaya, Fuego, Acatenango, and Agua, and other volcanic centers along the arc, although the actual volcanic stratigraphy is poorly defined. The GC Metro area is cut by a system of active faults that define the N-S-trending Guatemala City Graben. Steep ravines or barrancos, that are likely fault-controlled, deeply dissect the landscape causing high susceptibility to landslides. This geologic and tectonic setting make it ideal for investigating the interplay of Quaternary volcanic, seismic, and landslide hazards of the region. Field access facilitated by industrial partners and new road cuts provide the ideal location to leverage high-resolution outcrop and satellite-based imagery alongside geochemical, petrographic, and geochronological data that can be used to quantify recent and active geologic processes including the sequence, style, and timing of volcanic eruptions, the kinematic and displacement history of faults and past earthquakes, and study of the underlying properties leading to landslide failure. The Guatemala Geohazards IRES students will have an unprecedented opportunity to develop field and laboratory skills in volcaniclastic stratigraphy, neotectonics, and landslide hazards while building international experiences and collaboration with Guatemalan students, mentors, and professionals.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.
