12geol 303 Plate Tectonic Report 10 Points This assignment is due online Friday, 6 Mar, by 3 PM. You will turn in your assignment (the answers to the questions below) in Blackboard Turnitin by uploading your Word file. Please submit your work directly into Blackboard. Papers are graded and grades are submitted electronically. Do not email your paper. No late papers accepted at all. Length of report: 300 words. Do NOT re-write the questions. Just answer them, numbered and in order. Use your own words only. No plagiarizing! It is okay to write down lecture notes verbatim. References are not allowed; answers must be based on lecture notes and your understanding of the subject. Your answer to question 2 must be detailed and complete (more than 2/3 of your paper). The questions pertain to a specific map indicated by a large black arrow, showing the land affected by a line with little triangles. You must read a tectonic map, as done in lecture, to identify this location. Please answer all questions clearly, concisely, and in order, numbered.

The location indicated on the map is characterized by a convergent plate boundary, where two tectonic plates are colliding. This type of boundary is known as a subduction zone, a site where one oceanic plate is thrust beneath a continental or another oceanic plate, resulting in significant geological activity such as earthquakes, volcanic eruptions, and mountain building. The dominant tectonic regime involves the oceanic plate—the Pacific Plate—descending beneath the continental or smaller plates, leading to subduction-related phenomena including deep-focus earthquakes and volcanic arcs like the Cascade Range or the Andes, depending on the region. The plates involved are primarily the large Pacific Plate and the adjacent smaller plates, such as the North American Plate or other relevant Eurasian or Philippine Sea plates, depending on the specific geographic setting. The process is characterized by the progressive sinking of the denser oceanic lithosphere into the mantle, forming a trench along the coastline. The velocity of the oceanic plate in this region is approximately 8.0 centimeters per year. Natural hazards associated with this region include earthquakes, tsunamis, volcanic eruptions, landslides, and coastal erosion. These hazards are a direct consequence of the ongoing subduction process and tectonic activity. Southeast of this region, in the Pacific Ocean, there is a transform boundary connecting the subduction zone to the mid-ocean ridge system, specifically the Pacific-Antarctic Ridge or the East Pacific Rise, depending on the precise map details. Regarding public awareness, populations in this tectonically active region tend to have variable levels of hazard awareness; coastal communities often recognize the risk of tsunamis and earthquakes but may lack comprehensive preparedness or understanding of all potential dangers. Education initiatives and hazard mitigation programs are crucial in reducing vulnerability to these natural events. References Bird, P
