Seismic Wave Analysis and Epicenter Determination

The video tutorial guides students through a virtual earthquake lab, starting with accessing the platform and generating seismograms for different regions. It explains how to measure SP intervals from seismograms and use these measurements to calculate the distance to an earthquake's epicenter. The tutorial also covers triangulating the epicenter using calculated distances and provides instructions for further exploration and submission of work.

What is the first step to begin the virtual earthquake lab?
