Volcanic hazards map for Augustine Volcano, Alaska (Waythomas and Waitt 1998), illustrating areas that could be affected by hazards such as tsunami (salmon areas around the coastline), pumice rafts (purple dotted line), directed blasts (green dashed line), and debris avalanches (red dashed line) in addition to the hazards expected during a typical eruption such as pyroclastic flows and surges (orange zones), lahars, and tephra (insets). Overall, seven hazards are depicted on this map, including insets (eight, if pyroclastic surges and flows are counted separately). This is also an example of a map produced as a “large poster with an accompanying report.” A high-resolution version of this map can be accessed via the Volcanic Hazard Maps Database: VHMD ID 566.
