Focus On Earthquakes provides a comprehensive description of the causes and consequences of earthquakes. Written by respected professors and Earth science authors Ed Tarbuck and Fred Lutgens and illustrated by Dennis Tasa, this app/book will be of interest to anyone who wants to learn about earthquakes. For schools, this interactive app/book can be used as an in-class tool or for independent study.

Topics covered include:
  • the causes of earthquakes and the relationship between earthquakes and faults
  • earthquake waves, seismometers, and earthquake detection
  • locating the source and measuring the size of earthquakes
  • earthquake damage and large historical quakes
  • tsunamis, firestorms, landslides, and liquefaction
  • earthquake prediction
  • plus a discussion of the relationship between earthquakes and plate tectonics

This new-media textbook provides illustrations, photos, narrated animations, and slide shows that aid in understanding the concepts presented.

Version 1.2
$3.99

This animation shows slippage along the fault and how it allows the deformed rock to "snap back." This is similar to what occurred during the 1906 San Francisco earthquake along the San Andreas fault.

Version 1.2
$3.99

This animation shows tsunami wave development with estimated speeds at different water depths resulting from displacement on the ocean floor.

Version 1.2
$3.99

Throughout the app you have a chance to review what you've read by answering multiple choice and true-false questions.

Version 1.2
$3.99

After reading the material, you can test your knowledge by typing answers in your own words to important essay questions.

Version 1.2
$3.99

The EARTHQUAKE TRACKER feature gives the user control over the display of quake magnitudes, focus depths, and events within the last hour to last week as well as historical quakes and recent volcanic activity on a 3D globe. Earthquake data is obtained from the USGS data feed every 5 minutes (with internet connection).

Version 1.2
$3.99

You may also view recent earthquakes on a 2D flat map. Map controls allow you to select which type of plate boundaries you would like to see plus the different map views showing physiographic features, continents, or countries. All controls apply to both the 2D and 3D views.

Version 1.2
$3.99

This narrated animation shows complex S waves in action and their snake-like movement.

Version 1.2
$3.99

Real-life photos reveal the destructive powers of earthquakes. This photo shows the damaging effects of the Northridge, California earthquake in 1994.
