 Across the United States, the past week has seen a series of moderate but notable earthquakes with Alaska and the Pacific Northwest drawing particular attention. On Friday afternoon, a magnitude four point six earthquake struck sixty-four miles from Anchorage, continuing a pattern of ongoing seismic activity in southern Alaska. Earlier in the week, several small to moderate quakes were recorded near Fairbanks and Anchorage, including readings between magnitude two point zero and three point two. The consistency of these low to mid magnitude events aligns with Alaska’s reputation as one of the most seismically active regions in North America, and they serve as a reminder of the persistent tectonic movement along the Alaska-Aleutian subduction zone, as detailed by Earthquake List.

The Pacific coast also experienced activity, including a shallow magnitude five point nine earthquake in the North Pacific Ocean two hundred fifteen miles from Eugene, Oregon, on Thursday evening, followed by a shallow five point one aftershock approximately one hundred forty-seven miles from Coos Bay. These offshore quakes, while not causing significant damage, highlight the ongoing stress along the Cascadia subduction zone, which scientists monitor closely due to its potential for much stronger events. The Bay Area of California saw a magnitude four point three quake near Berkeley on Monday night, consistent with the localized faults that run through the region.

California remained active throughout the week, with several small earthquakes recorded near Santa Rosa, Moreno Valley, and San Diego. Nevada also registered a magnitude three point nine event northwest of Las Vegas. Hawaii experienced multiple minor tremors south and southwest of Hilo, all near magnitude two to two point six. According to real-time earthquake tracking from the United States Geological Survey, these quakes are within the historical norm for the areas, emphasizing the everyday reality of seismic risk in tectonically complex areas of the United States.

Internationally, the biggest events of the past seven days include a magnitude five point nine earthquake near Quepos, Costa Rica, and a magnitude five point four quake in the Southeast Indian Ridge, as reported by Earthquake Track. A world earthquake report from Volcano Discovery lists six earthquakes of magnitude five and above worldwide over the past twenty-four hours, with broader global seismic activity showing normal background levels.

While no major destruction has been reported in the United States or globally from these recent events, the sustained frequency of moderate earthquakes, particularly in Alaska and the Pacific offshore zones, continues to offer valuable data for hazard assessment and public preparedness efforts. Emerging patterns reiterate the ongoing movement of tectonic plates along major boundaries, keeping earthquake risk a persistent consideration for communities across the country.
