Measuring Earthquake Magnitude app for iPhone and iPad

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.
