During the 1994 Northridge Earthquake, CERT volunteers shut off utilities, distributed water, made telephone calls, passed out informational fliers and in some cases helped pull survivors from the rubble.

On June 10, 1999, the Olympic Pipeline ruptured in Bellingham, Washington.  CERT teams helped out in the Emergency Operations center by answering phones, monitoring radio traffic and keeping logs of events.  Their disaster psychology training was used as they cared for themselves and those around them during times of stress. 

On February 28, 2001, the 6.8 magnitude Nisqually Earthquake struck western Washington.   Many CERTs in the effected areas self-activated, checking their homes and neighborhoods for damage.   Some teams helped in their local EOCs, answering phones and giving the public information.

In 2004, wildfires ravished some parts of Arizona, overwhelming fire crews and resources.  CERT teams helped with evacuations during that time and helped with reseeding burned out areas afterward.

In 2004, following Hurricane Isabel in Virginia, CERTs filled sandbags, directed traffic, evacuated residents, identified and marked downed power lines and performed damage assessments.  They did supply runs when needed and were on hand in neighborhoods to bail out basements, patch roofs, move fallen trees and survey damage.  They set up and organized an evacuation center and distributed ice and water to citizens in need.

CERT members distributed evacuation warning flyers to residents threatened by the Simi Valley wildfires in 2004.  They delivered food and drink to the front lines,  took digital photographs to aid in damage assessment, directed traffic to and from the danger area and also aided the ECC.
