This project analyzes tsunami evacuation times for three Oregon coastal cities: Florence, Seaside, and Coos Bay. Using a range of Python libraries, including GeoPandas, OSMnx, and NetworkX, shapefiles were processed for city limits, assembly areas, and tsunami scenarios. The resulting data was reprojected and clipped, and network analysis techniques were applied to calculate walking times from various nodes to assembly areas, simulating evacuation routes. For-loops were used to calculate multiple node-to-assembly-area combinations efficiently. The results were visualized using Matplotlib and Folium, highlighting which areas were hardest to evacuate. This project demonstrates the importance of geospatial network analysis in disaster preparedness, particularly in assessing evacuation accessibility in coastal communities.
