Estimated Intensity
Moderate (5/10)
A strong traffic spike was detected across inland San Diego and Riverside counties at 10:57 AM PDT on March 16. Camp Pendleton had issued an official noise advisory for live-fire training with high explosive munitions from March 14-22, running 24 hours a day. The inland detection pattern, south and east of the base's Whiskey and Zulu impact areas, matches the expected sound propagation from ordnance detonations at those ranges. Camp Pendleton warns that atmospheric conditions can amplify the sound up to 50 miles away.
