Park earthquake history

A chronological archive of seismic events mapped by proximity to forest boundaries

Recorded Earthquake History and Seismic Activity near Okanogan–Wenatchee National Forest

Review a detailed catalogue of historical earthquake events that have occurred in the geographic vicinity of the Okanogan–Wenatchee National Forest. This collection organizes seismic records by date, magnitude, depth, and calculated distance from forest boundaries to provide a clearer view of regional activity. All data is sourced from historical USGS records and reflects tracked epicentres within the broader Cascade Range and Okanogan highlands region.

Okanogan, Wenatchee National Forest

The Okanogan–Wenatchee National Forest is a large U.S. National Forest in north-central Washington state, straddling the eastern slopes of the Cascade Range and extending into the Okanogan highlands along the Canadian border. Managed by the U.S. Forest Service from its headquarters in Wenatchee, the combined forest is one of the most extensive in the Pacific Northwest and contains significant portions of multiple designated wilderness areas, including the Pasayten Wilderness and the Lake Chelan-Sawtooth Wilderness. The forest's landscapes contrast sharply from west to east, transitioning from moist coniferous forests and alpine lake country in the Cascades to arid high-elevation steppe in the Okanogan region. This gradient supports a wide range of ecological communities, including substantial tracts of old-growth lodgepole pine, mixed conifer forests, glacial peaks, and remote wilderness lakes. Natural fire has long shaped the ecology of the area, with several major wildfire complexes in recent decades influencing both forest management and regional air quality. The Okanogan–Wenatchee is significant for its ecological diversity, its wilderness character, and its role connecting the North Cascades ecosystem with the broader interior Pacific Northwest. It serves as a major landscape for hiking, horseback travel, backcountry solitude, and conservation of the transitional forests that define the eastern Cascades.
