M4.6 Earthquake: 80 km SSE of False Pass, Alaska — Alaska Trail & Access Update

M4.6 Earthquake Near False Pass, Alaska: Chugach State Park Trail Closures & Hiking Safety (2026)

An M4.6 earthquake, measuring 4.6 on the Richter scale, struck 80 kilometers (50 miles) south-southeast of False Pass, Alaska, on Tuesday, prompting temporary trail closures and raising concerns about hiking safety within the Chugach State Park region.

Recent seismic activity is impacting outdoor recreation across Southcentral Alaska, particularly within the vast Chugach State Park. The earthquake, which occurred at 10:15 AM AKDT, triggered immediate assessments of trail conditions and access points. While the epicenter was offshore, the shaking was felt as far inland as Anchorage, prompting park officials to implement precautionary closures. Specifically, the popular Flattop Mountain Trail and sections of the Resurrection Pass Trail are currently closed pending thorough inspections. This follows a series of smaller tremors in the region over the past month, contributing to a heightened awareness among hikers and anglers alike. The Kenai Fjords National Park area is also being monitored closely, though no immediate closures have been announced. This event underscores the dynamic nature of Alaska’s landscape and the importance of staying informed before heading out.

Alaska Trail Conditions: Chugach State Park & Earthquake Impacts

The Chugach State Park system, a cornerstone of outdoor activity for Anchorage residents and visitors, is experiencing significant adjustments due to this latest seismic event. Trails like the Devil’s Pass Trail, known for its stunning views and challenging ascent, are being carefully evaluated. Hikers planning trips to areas near Exit Glacier, a major draw for Kenai Fjords visitors, should be aware of potential instability and altered access routes. The Hatcher Pass Road, a popular route for accessing trails like the Crow Pass Trail, remains closed while engineers assess potential damage. Furthermore, the increased seismic activity is prompting a review of avalanche forecasts in the upper Chugach, potentially impacting shoulder-season hiking plans. Anglers targeting salmon runs along the Eagle River Nature Center should also exercise caution and check with local authorities for updates.

What Hikers Should Do: Earthquake Safety in Alaska

Given the increased seismic activity, hikers in Southcentral Alaska need to prioritize safety. First, always check the Alaska Department of Natural Resources website and local park service alerts for the latest trail closures and warnings. Second, be acutely aware of your surroundings – look for signs of ground movement, unstable slopes, and potential rockfalls. Carry a map and compass, and know how to use them, as cell service can be unreliable. Third, pack a well-stocked emergency kit including extra food, water, a first-aid kit, and a headlamp. Fourth, and crucially, be prepared for rapidly changing weather conditions – Alaska’s mountains can experience dramatic shifts in temperature and precipitation. Finally, remember that you are in bear country; carry bear spray and know how to use it effectively.

Alaska Outdoor Context

Alaska’s unique geological setting makes earthquakes a regular occurrence, reminding us of the powerful forces shaping this incredible landscape. For generations, Alaska Native communities have relied on these lands for subsistence, and respecting traditional use areas and practices is paramount. The shoulder season – spring and fall – presents both beautiful hiking opportunities and increased challenges due to unpredictable weather and potential trail damage. Staying informed and prepared is essential for enjoying the Alaskan wilderness responsibly.

Plan your hike, stay safe, and explore the beauty of Alaska – but always prioritize your well-being and respect the power of nature.
