Tectonic Setting Of southern Alaska
Southcentral Alaska is a region where multiple tectonic forces converge, leading to frequent seismic activity. The area’s quakes are generated by several tectonic features.
- Megathrust Fault: The strongest quakes originate from the megathrust fault between the subducting Pacific and overriding North American plates. The 1964 M9.2 Great Alaska Earthquake occured here.
- wadati-Benioff Zone: Intermediate-depth seismicity (below 20 miles) occurs in this zone, where the Pacific Plate descends. The 2016 M7.1 Iniskin and the 2018 M7.1 Anchorage earthquakes are notable examples.
- Crustal Seismicity: Attributed to faults and folds of the Cook Inlet basin, the Castle Mountain Fault, and a diffuse zone from northern Cook inlet to the Denali Fault. The April 1933 M6.9 earthquake is associated with these structures.
Historical Earthquakes In the Region
Alaska has a history of notable seismic events. the 1964 Great Alaska Earthquake remains the second-largest earthquake ever recorded.
Other notable events include:
- 1964 Great Alaska Earthquake (M9.2): Originating under Prince William Sound.
- 2016 Iniskin Earthquake (M7.1): Produced significant ground shaking.
- 2018 Anchorage Earthquake (M7.1): Resulted in structural damage.
- 1933 Earthquake (M6.9): Caused considerable damage in Anchorage.
- 1984 Sutton Earthquake (M5.6): Generated by the Castle Mountain Fault.
Preparing For Future Earthquakes
Residents of Southcentral Alaska should be prepared for future seismic events. It’s crucial to have an emergency plan, including a supply kit with essential items such as water, food, and first-aid supplies.Regularly review and practice your plan with your family.

| Emergency Kit | Water, non-perishable food, first aid supplies, flashlight, radio |
| family Plan | Meeting place, communication strategy, evacuation routes |
| Home Safety | Secure heavy objects, know how to shut off utilities |
Understanding Earthquake Risks In Alaska
Alaska’s unique geological location makes it one of the most seismically active regions in the world.The constant interaction between the Pacific and North American plates results in frequent earthquakes of varying magnitudes. Residents must stay informed and prepared to mitigate the risks associated with these events.
Did You Know? Alaska experiences more than 40,000 earthquakes each year, although most are too small to be felt.
Staying informed through official channels and community resources is crucial for effective earthquake preparedness. Local emergency management agencies and geological surveys provide valuable data and guidance. Moreover, participating in community drills and workshops can enhance preparedness and response capabilities.
