Measuring Earthquake Magnitude 1.1

Study how the magnitude of an earthquake is measured in an interactive environment. Complete experiments, answer questions, make predictions, and take quizzes—learn science in a whole new way.

Take the role of a scientist determining the magnitude of an earthquake. Receive reports from different seismic stations. Take measurements of the data and calculate a final result.

• Analyze graphical data from different seismograph stations.
• Determine the amplitude of the P and the S waves as measured by each station.
• Manipulate a distance – amplitude chart to determine the magnitude of the quake.
• Verify your result by repeating it using different data from different stations.

App features:
• Discover how the magnitude of an earthquake is measured using seismograph data.
• Learn about the Richter scale and how it is used.
• Watch animations that explain the concepts.
• Test your knowledge with interactive tasks and quizzes.
