The Alaska Legislature established the Alaska Earthquake Information Center (AEIC) by statute in 1986. Home of the second greatest earthquake recorded in 1964 and the most seismically active state in the Union, Alaska has a selfish interest in monitoring earthquake activity within the state.
Alaska Earthquake Information Center (AEIC)
The Alaska Earthquake Information Center acts as a hub that receives data from hundreds of seismic sites located throughout Alaska. Additionally AEIC processes data received from the West Coast and Tsunami Warning Center in Palmer, Alaska. Staff at AEIC records the location and intensity of roughly 22,000 earthquakes each year. Data recorded by AEIC adds in making public warnings of earthquakes and is used to further research in the field.
Earthquakes in Alaska
Earthquakes result from the impact of great tectonic plates spread across the earth’s surface. The plates can slide along each other or one plate can override another. Alaska is located along the northern portion of the Ring of Fire, a circularly shaped line of volcanic and earthquake activity located in the Pacific Ocean. The Alaska part of Ring is composed of the North American Plate colliding with the Pacific Plate and the northwest movement of the Pacific Plate being subducted under the arc of the Aleutian Islands. The Aleutian Megathrust found under the island chain is the cause of large magnitude earthquakes in Alaska.
Earthquake Preparedness
Many organizations joined AEIC to prepare an informational booklet on how respond and prepare for an earthquake. Are you prepared for the next big EarthQuake in Alaska is available as a PDF download. Some suggestions include:
- During and After an Earthquake – If you are inside, take cover under a study desk or table and stay away from windows and heavy objects like refrigerators. If you are outside, get to an open area away from buildings and powerlines. If you are near the coast, move to higher ground and much further inland
- Avoid the use of open flame sources like matches or lanterns after an earthquake until you are sure there are no propane, fuel oil or natural gas leaks. Use a flashlight
- Designate a contact located out of state to relay information about you and your family. Think about you would contact family members after an earthquake occurs
- Prepare a cache of emergency supplies. Having things like a flashlight, radio, first-aid kit, warm clothes and the like in one accessible location will pay great dividends in an emergency
- Secure things like hot water heaters, bookshelves and fuel tanks to prevent them from falling during an earthquake
The Alaska Earthquake Information Center is a great resource for information on current earthquake activity, provides data on historic earthquakes, and is a rich source of practical knowledge on earthquake response and preparedness.
