The image on the right is the eruption of Mount Saint Helens in 1980. That natural hazard resulted in 57 deaths and the destruction of thousands of acres of forest and wildlife. A couple of months before the eruption, scientists installed monitoring systems and watched as several small-magnitude earthquakes rumbled beneath the volcano repeatedly. The pressure built and the volcano was seen to be bulging on one side. This was an indication that the magma was rising inside and pressure was buildin...

This learning resource focuses on analyzing the characteristics, impacts, and prediction methods of atmospheric and geologic natural hazards, using the 1980 Mount St. Helens eruption as a case study. It provides students with a word bank and fill-in-the-blank questions to explore the geological events surrounding the eruption, the progression of prediction methods before and after 1980, and factors affecting risk assessment and damage patterns. The resource delves into atmospheric hazards, evaluates risk factors associated with different types of natural hazards, including floods, hurricanes, and tornadoes, and discusses their detection and warning methods. Furthermore, it incorporates activities to help students analyze plate tectonics and the relationship between geologic hazards and tectonic boundaries, culminating in a risk assessment task and a comparison of atmospheric and geologic hazards.
