Glossary

Date : Blast date and time

Reference : Blast identification

Length : Blast length or the period between the detonation of the first shot and the detonation of the last shot in a sequence.

Seismograph : Measuring instrument equipped with a geophone and a microphone. The geophone detects ground motion and vibrations passing through the earth’s crust. The microphone detects air pressure variations..

Wind Direction : Indicates wind direction

Vibration : Indicates ground motion.

Decibels (dB) : Indicates air pressure variations.

Below Detection Limit (BDL) : Indicates seismograph has not been triggered. Seismograph is not triggered when ground vibrations are below 1 mm/s.

Not available (NA) : Indicates value is unavailable.

ms : Length is measured in milliseconds (1,000 ms = 1 second).
