Natural Hazards

Cartography of Natural Hazards

The recommended response to floods, tsunami, and volcanic hazards is for people to seek high ground, and many hazard maps produced for the public emphasize the safety of higher elevations. Because not all people find contour or shaded relief maps to be intuitive, we are researching the effectiveness of 3D perspective maps as tools for public outreach.
