Application of volcanic ash deposits to predict future geologic hazards in the Tokyo Metropolitan Area, Japan

Japan is one of the most geologically active countries on Earth. It has seen many volcanic eruptions throughout its history, along with earthquakes and tsunamis due to plate tectonic movements. Over time, these eruptions have deposited many volcanic ash layers onto the ground, where they are buried and preserved. We can use these ash layers to determine volcanic activity over time. Additionally, by observing how the previously horizontal ash layers have deformed after they have been buried, we can determine how and when tectonic movements have influenced the area in the past. We will examine one of three potential cores taken from the Tokyo Metropolitan Area and compare its ash layers to other sampled cores from past studies. By doing so, we will be able to understand some of the past geologic processes that have occurred in the region. TO BE CONT’D
