7.0 magnitude quake hits Alaska; witnesses recall powerful shaking

A 7.0 magnitude earthquake rocked buildings Friday morning in Anchorage and caused lamp posts and trees to sway, prompting people to run out of offices and seek shelter under office desks. Back-to-back earthquakes measuring 7.0 and 5.7 rocked buildings and shattered roads in Anchorage, sending people running into the streets and briefly triggering a warning to residents in Kodiak to flee to higher ground for fear of a tsunami. The National Tsunami Warning Center has issued a tsunami warning for coastal zones of southern Alaska following the earthquake.
