A 7.9-magnitude earthquake that struck off the coast of Alaska early Tuesday morning led the National Weather Service to warn that a tsunami could follow along the West Coast. Residents in Alaska received cell phone text warnings and emergency storm sirens blared in Kodiak, just miles from the earthquake's epicenter. While the warning has since been lessened to an advisory, these tweets and photos about the Alaska earthquake show how scary it was for people who were there.

The key advice from officials across Alaska was to get to higher ground. The Anchorage Office of Emergency Management explained what the tsunami warning meant. "Tsunami warnings mean that a tsunami with significant inundation is possible or is already occurring. Tsunamis are a series of waves dangerous many hours after initial arrival time. The first wave may not be the largest," the office warned. Anchorage, the largest city in the state, was not in the warning area.

Even as far as California, emergency officials were warning residents of potential destruction. "If you are w/in SF & 3 blocks of the Pacific Coast or w/in 5 blocks of SF Bay, PREPARE TO EVACUATE SO YOU ARE READY IF EVACUATION IS NEEDED. Check on neighbors who may need help," the city tweeted, accompanied with photos of the warning written in other languages. The potential danger was real, and these tweets show why.
