Expect to hear some strange sounds coming from Joint Base Myer-Henderson Hall tomorrow (Thursday).
The base will be participating in the Great SouthEast ShakeOut, a regional earthquake drill that’s to take place at 10:18 a.m. In addition to asking those on the base to “drop, cover and hold on,” JBM-HH will be testing its “Big Voice” public address system, which may be heard outside the base.
From a press release:
The ShakeOut is a regional earthquake drill in which participants simultaneously practice the recommended action during an earthquake. This action is known as “Drop, Cover, and Hold On”, which means to:
DROP to the ground
Take COVER by getting under a sturdy desk or table
HOLD-ON to it until the shaking stops
In support of the great shakeout earthquake operation JBM-HH will conduct a test of the giant voice public address system. The test will be conducted on both the Fort McNair and Fort Myer/Henderson Hall portion of JBM-HH at 11 a.m. Residents on and immediately outside the installation can expect to hear the test.
