Hazards Have Seasons; The Ring of Fire
Captions available
The idea
Plate tectonics explains why nearly ninety percent of earthquakes and volcanoes occur along the Pacific's outer edges, the Ring of Fire. Hazards have seasons: tornadoes in spring and early fall, wildfires in late summer, hurricanes peaking in August and September.
In practice
America has more tornadoes than the rest of the world combined.
Where people slip
Hazards are taught here as process, not safety lines.
