ANCHORAGE - A drill testing the state's ability to respond to a disaster is set to begin Monday.
Alaska Shield 2010 takes place in Cordova, Valdez, Anchorage, Unalaska and the Matanuska-Susitna Valley.
The six-day exercise will involve 4,000 participants statewide, as well as National Guard units from five other states.
The drills are held every two or three years. This year's focus is natural disasters, and the scenario is an earthquake.
Jeremy Zidek, spokesman for the Division of Homeland Security and Emergency Management, says the response systems that will be tested could also be applied to wildfires, flooding and other natural disasters.
