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.

该奖项由2021年美国救援计划法案资助（公法117-2）。本次危地马拉地质灾害国际学生研究经验的目标（危地马拉地质灾害IRES）项目是为美国本科生培养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，并通过与危地马拉学生，教授和工业合作伙伴并肩合作来学习国际合作，以解决危地马拉城地堑地质灾害长期第四纪记录的研究问题。危地马拉的板块边界使该国面临许多自然灾害，包括来自四个震源区的地震、沿活跃的中美洲火山弧沿着的火山爆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IRES项目有可能增加妇女和代表性不足的少数民族进行研究，完成学士学位，并继续研究生课程和地球科学的职业生涯的数量。我们的IRES也带来了多样性，我们的榜样与六位西班牙裔导师和三位女教师导师面对。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，这将是学生未来在日益全球化的劳动力和经济中取得成功的宝贵经验。 危地马拉城（GC）地铁蔓延在一个由火山凝灰岩和熔岩流组成的高原上，这些火山来自与该地区接壤的南部和西南部的活火山，包括帕卡亚，富埃戈，阿诺特南戈和阿瓜，以及其他火山中心沿着弧，尽管实际的火山地层学定义不清。GC地铁区被一个活动断层系统切割，该断层系统定义了南北走向的危地马拉城地堑。陡峭的峡谷或峡谷，可能是断层控制的，深深地解剖了景观，导致对山体滑坡的高度敏感性。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选择。工业合作伙伴和新的道路切割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，包括火山爆发的序列，风格和时间，断层和过去地震的运动学和位移历史，研究导致滑坡破坏的潜在性质。危地马拉地质灾害IRES的学生将有一个前所未有的机会，以发展火山岩地层学，新构造学和滑坡灾害领域和实验室技能，同时建立国际经验和与危地马拉学生，导师和专业人士的合作。这个奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
