What would happen if Vancouver was hit by a Tsunami? I learned some critical GIS analytical skills to visualize areas in danger and gather useful information on what facilities would be in danger.
Click here to see a map of the City of Vancouver with land use areas that would be affected from a Tsunami and highlighted proposed signage.
To figure out what areas would be in danger, I first buffered the shoreline to 1km off the coast. I then reclassified the DEM to separate anything that was below 15m elevation. After this, I intersected the new buffered area to areas below 15m elevation to create a distinguishable danger zone for easier analysis.
City of Vancouver’s total area in danger is about 15%. To get this answer I divided the sum of Vancouver’s total area with the total sum of the area in danger.
The following healthcare and educational facilities would be in danger:
| Education | Health Care |
| St. Anthony of Padua
Ecole Rose des Vents Heritage 3R’s School Vancouver Montessori School False Creek Elementary Emily Carr Institute of Art & Design Henry Hudson Elementary Institute of Indigenous Government |
False Creek Residence Broadway Pentecostal Lodge Yaletown House Society Willa Cathay Care Home |
To get these answers I clipped both the layers containing schools and healthcare to my danger zone layer and looked at each new layers attribute tables.
