App Description

Study how the location of an earthquake is determined 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 location 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 time between the P and the S waves as measured by each station.
• Triangulate the earthquake by determining its distance from each of the stations.

App features:
• Discover how the location of an earthquake is measured using seismograph data.
• Learn about triangulation, a method which is used to determine location.
• Watch animations that explain the concepts.
• Test your knowledge with interactive tasks and quizzes.
• Want more? Check out the AC library in the App Store.
