Spatial distribution, magnitude, frequency, regularity and predictability of volcanic hazard events
Volcanic hazards differ in where they occur, how powerful they are, how often they strike, and how reliably scientists can forecast them. These five characteristics shape how dangerous a volcano really is.
Real World
Kilauea in Hawaii has erupted almost continuously since 1983, making it highly predictable and allowing the USGS Hawaiian Volcano Observatory to issue real-time lava flow maps — contrast this with unpredictable supervolcano events like Yellowstone.
Exam Focus
Use all five characteristics as a framework in extended answers; addressing only distribution and magnitude misses easy marks on frequency and predictability.
