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).
