US Earthquake Activity Surges: 700+ Quakes Hit Nation in March as Alaska and Central US Show Heightened Seismic Patterns

In the past week, the United States has seen a surge in seismic activity, with the United States Geological Survey recording over seven hundred earthquakes of magnitude one point five or higher nationwide. According to the United States Geological Survey, the strongest this month hit Unalaska in Alaska at magnitude six point one on March twenty-third, felt strongly offshore near Nikolski. Another significant event struck Alaska offshore, two hundred twenty-four kilometers east-southeast of Attu Station, at magnitude six point four on March fourth, with no reported damage. On March fifth, a magnitude four point nine earthquake rattled Red River Parish in Louisiana, the largest there in decades and centered in Cushatta, according to United States Geological Survey data. This tremor highlighted activity along the region's fault lines, with no major injuries but notable shaking reported widely. Earlier, on March first, a magnitude four point one quake hit five kilometers east of Cowles, Nebraska, at shallow depth of three kilometers, followed by two magnitude two point six aftershocks the next day. United States Geological Survey received over one thousand eight hundred fifty felt reports, marking it as the area's biggest this year amid twenty-two quakes in the past three hundred sixty-five days. Alaska continued shaking with a magnitude five point seven event on March sixth near Kalifornsky on the Kenai Peninsula, at nine point three kilometers depth, rated green for low impact by the Global Disaster Alert and Coordination System. On March tenth, a modest magnitude two point three struck Sleepy Hollow in Westchester County, New York, about twenty-five miles north of Manhattan, felt in parts of Connecticut, as reported by the United States Geological Survey and WFSB news. In South Carolina's Midlands, the fifth quake of two thousand twenty-six hit near Lake Murray on March first at magnitude two point two, part of a cluster including magnitudes two point eight, two point zero, one point eight, and two point five since mid-February, all vicinity of Pine Island with no damage. Experts confirm the Lake Murray Dam can withstand up to magnitude seven point three. These events reveal emerging patterns: heightened activity in tectonically active Alaska and the central United States, including rare intraplate quakes in Louisiana and Nebraska, possibly linked to regional stresses. Minor swarms dominate, with over one hundred eight quakes in twenty-four hours ending March eighth, per United States Geological Survey, underscoring the nation's frequent low-level seismicity without widespread destruction. Worldwide, larger quakes like magnitude five point five south of the Kermadec Islands on March tenth drew attention, but United States events remain the focus amid stable monitoring.
