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

该奖项由《2021年美国救援计划法案》(公法117-2)整体资助。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)项目的目标是培养美国本科生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的综合野外和实验室研究方法，并通过与危地马拉学生、教授和工业合作伙伴并肩合作，学习国际合作，解决危地马拉市格拉本第四纪地质灾害的长期记录的研究问题。危地马拉板块边界的设置使该国面临许多自然灾害，包括来自四个震源区的地震、中美洲活跃火山弧沿线的火山喷发，以及因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。危地马拉地质灾害研究所项目有可能增加从事研究、完成学士学位并继续从事地球科学研究生课程和职业的妇女和未被充分代表的少数群体的人数。我们的IRES还为我们的榜样带来了多样性，有6名拉美裔导师和3名女性教职员工导师。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，将为学生提供一个无与伦比的文化丰富途径，以及一种全球合作的经验，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)地铁延伸到一个由火山凝灰岩和熔岩组成的高原上，这些火山凝灰岩和熔岩从活火山向南部和西南部与该地区接壤，包括帕卡亚、富戈、阿卡特南戈和阿瓜等火山中心，以及沿弧线的其他火山中心，尽管实际的火山地层定义不清。GC Metro地区被一系列活动断裂切割，这些活动断裂定义了北S方向的危地马拉城地块。陡峭的峡谷或巴兰科，很可能是受断层控制的，对地形进行了深度剖析，导致极易发生山体滑坡。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。工业合作伙伴和新的道路开挖为利用高分辨率露头和卫星图像以及地球化学、岩相学和地质年代学数据提供了理想的位置，这些数据可用于量化最近和活跃的地质过程，包括火山喷发的序列、样式和时间、断层和过去地震的运动学和位移历史，以及导致滑坡破坏的基本属性研究。危地马拉地质灾害研究所的学生将有一个前所未有的机会发展火山碎屑地层学、新构造运动和滑坡灾害方面的野外和实验室技能，同时积累国际经验，并与危地马拉学生、导师和专业人员合作。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势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.
