Understanding Earthquake Risks in Anchorage

Seismic Activity in Alaska

Alaska is part of the Pacific Ring of Fire, a region known for its high seismic activity. The state experiences a large number of earthquakes each year, with many of them being significant in magnitude. Anchorage, being one of the most populated areas in Alaska, faces a considerable risk.

Historical Earthquakes in Anchorage

Anchorage has experienced several major earthquakes throughout its history. The most notable is the 1964 Good Friday Earthquake, which was the largest earthquake ever recorded in North America, with a magnitude of 9.2. This earthquake caused extensive damage and had a lasting impact on the region.

Factors Contributing to Earthquake Risks

Several factors contribute to the earthquake risks in Anchorage:

• Location: Anchorage is situated near active fault lines, increasing the likelihood of seismic events.
• Geology: The local geology, including soil types and ground conditions, can amplify earthquake shaking.
• Infrastructure: The vulnerability of buildings and infrastructure to seismic activity is a critical factor in assessing risk.

Preparing for an Earthquake

Developing an Emergency Plan

Creating an emergency plan is essential for earthquake preparedness. This plan should include:

• Evacuation routes: Identify safe routes for evacuating your home, workplace, or school.
• Meeting points: Designate a meeting point for family members in case you are separated during an earthquake.
• Communication strategy: Establish a way to communicate with family members, such as a designated out-of-state contact.

Assembling an Emergency Kit

An emergency kit should contain essential supplies to help you survive in the aftermath of an earthquake. Key items to include are:

• Water: At least one gallon of water per person per day for several days.
• Food: Non-perishable food items such as canned goods, energy bars, and dried fruit.
• First aid kit: A comprehensive kit with bandages, antiseptic wipes, pain relievers, and any personal medications.
• Flashlight: With extra batteries.
• Radio: A battery-powered or hand-crank radio to receive emergency broadcasts.
• Whistle: To signal for help.
• Dust mask: To protect against airborne particles.
• Moist towelettes, garbage bags, and plastic ties: For personal sanitation.
• Wrench or pliers: To turn off utilities.
• Can opener: For canned food.
• Local maps: In case electronic navigation is unavailable.
• Cell phone with chargers and a backup battery

Securing Your Home

Making your home more earthquake-resistant can significantly reduce the risk of damage and injury.

• Anchor furniture: Secure heavy furniture such as bookcases, dressers, and televisions to the walls.
• Install latches: Use latches on cabinets and drawers to prevent them from opening during an earthquake.
• Secure appliances: Fasten appliances like water heaters and refrigerators to the wall studs.
• Reinforce structures: Consider reinforcing your home's foundation and other structural elements.

What to Do During an Earthquake

Drop, Cover, and Hold On

The recommended action during an earthquake is to drop to the ground, take cover under a sturdy piece of furniture, and hold on until the shaking stops. This technique provides the best protection from falling debris.

If Indoors

• Stay inside: Do not run outside during the shaking.
• Take cover: Get under a desk or table, or stand against an interior wall.
• Avoid windows and doors: Stay away from glass and anything that could fall.

If Outdoors

• Find an open space: Move away from buildings, trees, and power lines.
• Drop to the ground: Protect your head and neck.

If in a Vehicle

• Pull over: Stop the car as quickly and safely as possible.
• Stay inside: Remain in the vehicle until the shaking stops.
• Avoid bridges and overpasses: These structures are vulnerable to damage during an earthquake.

Actions to Take After an Earthquake

Check for Injuries

After the shaking stops, check yourself and others for injuries. Provide first aid as needed.

Expect Aftershocks

Aftershocks are smaller earthquakes that follow the main shock. They can occur within minutes, days, or even months after the initial earthquake. Be prepared for additional shaking and take the same protective actions as during the main earthquake.

Inspect Utilities

• Gas: If you smell gas or hear a blowing or hissing noise, open a window and get everyone outside quickly. Turn off the gas at the main valve if you can, and report the leak to the gas company.
• Water: Check for damage to water lines. If you suspect damage, turn off the main water valve.
• Electricity: Look for electrical system damage. If you see sparks or broken wires, turn off the electricity at the main breaker.
