Measuring Earthquake Intensity
The Earthquake Monitoring Station in the Gottesman Hall of Planet Earth features a recorder showing real-time ground shaking at stations in Alaska, Arizona, and Japan. The stations are part of a network that monitors global seismic activity to provide warnings.
A screen showing seismic activity uses red dots for that day's events, orange for the day before, yellow for the previous two weeks, and purple for the past five years. Yellow rings around each dot indicate the earthquake's magnitude. The screen shows both global and U.S. views.
