Project 2
Looking at a Seismograph: Can a volcanic eruption be detected?

Purpose

Seismometers are instruments that detect disturbances in Earth's crust. Used mostly for earthquake detection, they can also measure the turbulence of a volcano's magma activity. The disturbance or activity is recorded on a seismograph, a sheet of paper that shows the intensity of the activity. For this project you will construct a seismograph that will simulate the types of disturbances that indicate volcanic activity.
