A mass notification and earthquake drill will take place at the Marine Corps Air-Ground Combat Center at 10:19 a.m., Oct. 19, 2023, in conjunction with 2023 Great California ShakeOut Exercise.

The purpose of this drill is to test all mass notification systems, including the base-wide public address system and digital notifications, and provide an opportunity for all MCAGCC personnel to test their individual earthquake action plans. The exercise will prepare MCAGCC personnel and families to react in the event of an earthquake.

To receive notifications, update personal contact information, and add family members to the Marine Corps Mass Notification System, base personnel can click on the “Purple Globe” icon in their computer system. If there is no “Purple Globe” but you have access to the Marine Corps Enterprise Network, you can reach Self-Service via the following URL at
