7.2 earthquake strikes Alaska, authorities warn of possible tsunami

The Geological Survey reported Sunday that a magnitude 7.2 earthquake was recorded in the Alaska Peninsula region. In addition, the agency issued a tsunami warning for nearby areas after the earthquake was recorded. The depth was 20.3 miles. "At the time of this forecast, there have been 8 magnitude 3 or higher aftershocks, which are strong enough to be felt nearby, and 1 magnitude 5 or higher aftershocks, which are large enough to do damage," the report detailed.

According to the report, aftershocks could also be recorded. However, the agency recalled that "no one can predict the exact time or place of any earthquake, including aftershocks." It also asked citizens to be vigilant but remain calm.

Finally, the report added, "Our forecast changes as time passes, particularly during the first few days after a mainshock. These changes happen because of three things: the usual decrease of aftershocks as time goes on, larger aftershocks that trigger more activity, and changes in forecast modeling due to ongoing data collection."
