Strayos allows its users to enter "No Trigger" as an option to their seimograph readings for blast reporting. To enter this value, users will need to navigate to the Blast Performance tab > Vibration/Airblast Readings. 

Seismographs that have been added to the site will display, where there will now be a "No trigger" option to select. If selected, "No Trigger" will display on the blast report and vibration report.
