MARINE CORPS AIR GROUND COMBAT CENTER, Calif. -- A mass notification and earthquake drill will take place at the Marine Corps Air Ground Combat Center (MCAGCC) at 10:20 a.m. on Oct. 20, 2022 in conjunction with California’s 2022 Great ShakeOut Exercise.

The purpose of this drill is to test base notification systems 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 to in the event of an earthquake.

The drill will test all Mass Notification systems, including the base-wide public address system and digital notifications.

To receive notifications and 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 tray. If there is no “Purple Globe” but access to the Marine Corps Enterprise Network (MCEN), you can reach Self-Service via the following URL at
