Who Monitors Blasts

Blasting operations are overseen by government agencies at all levels, but when it comes to monitoring blast vibrations in the field, often it’s the blasting crew that sets up the seismograph. It’s also common for third-party consultants to record blast vibrations and report them to the blaster and sometimes to regulatory officials. In some jurisdictions, a regulator will be responsible for setting up a seismograph and recording blasts.

The information recorded by the seismograph is used by blasting specialists to evaluate blast design performance and ensure regulatory compliance.  Most importantly, it verifies that the vibrations are within standards set to protect houses and other structures.
