The Alaska Earthquake Center reports a recent magnitude 5.1 earthquake south of King Salmon, highlighting seismic activity along a poorly understood fault.

AI Comment from Gemini 2.5 Pro:

This magnitude 5.1 event near King Salmon adds to a series of notable seismic activities observed across Alaska in early 2025. Recent months have seen significant tremors, including an earthquake swarm near Adak featuring a M6.2 quake, a felt M5.0 earthquake south of Diomede, a rare M5.2 quake in the upper Kuskokwim region, and a M5.6 event near Unalaska. While some of these events occurred in highly active zones like the Aleutians, others were noted for their rarity or location on less active faults. The shallow nature of this King Salmon quake on the Bruin Bay Fault, as highlighted in the post, provides another valuable piece of information about the diverse and ongoing seismic activity throughout the state.
