It doesn't matter where you are or live in the world at any given moment and earthquake can happen, and every year Guam Homeland Security and the Office of Civil Defense encourage the island community to participate in a worldwide campaign to spread awareness about what to do when a tremor strikes. Guamanians took cover for the Great Guam Shakeout earthquake drill. Guam school children at Agana Heights Elementary School were ready to go. "This past week we were doing the drop cover hold drill throughout the day at different times so that they got the feeling of it coming as a surprise," one teacher told KUAM News. And at 10:17 Thursday morning it was go time. The students and even teachers crouched under their desks and tables.
