I understand that the timing of seismic waves is very important. How can I ensure sufficient accuracy?
A The simplest solution is to log data onto a PC that is connected to the Internet, with the clock automatically being set via an Internet timeserver. Alternatively, attach an atomic radio clock or GPS time server to your PC. However, for your initial experiments it may be enough to set and monitor your PC’s internal clock manually by radio beeps or your quartz wristwatch.
