RMS: Measuring Risk by Location
Risk isn't always easy to perceive. There are many factors involved, from the cost of the risk to its long-term effects. This heat map, provided by the risk management company RMS, displays risks related to catastrophic events: earthquakes, hurricanes, severe storms (including tornados and hail), wind storms, wildfires and volcanoes.
An insurance company might use it to determine the "probability of loss" related to such an event. The data comes from an internal database operated by RMS.
