U.S. Earthquake Activity Remains Steady With Notable 6.0 Magnitude Quake in Hawaii

About this episode

This episode discusses the recent steady earthquake activity in the U.S., highlighting a notable 6.0 magnitude quake in Hawaii.

In the past week, earthquake activity across the United States has been steady but mostly moderate, with the most notable shaking centered in Hawaii and Alaska. According to the United States Geological Survey, the largest quake affecting U.S. territory in the last several days was around magnitude 6.0 off the coast of Honaunau Napoopoo on the Island of Hawaii, part of an ongoing sequence associated with magma movement and stress changes along the island’s active volcanic systems. USGS data also show multiple smaller events, generally below magnitude 4, scattered across the rest of Hawaii, consistent with its status as one of the most seismically active U.S. regions. Farther north, USGS reports a magnitude 4 plus earthquake south southeast of Nikolski in the Aleutian Islands of Alaska, one of dozens of small to moderate quakes recorded along that subduction zone in the last week. These events fit a long term pattern in which Alaska experiences the largest share of U.S. earthquakes due to the ongoing convergence of the Pacific and North American plates. On the mainland, networks summarized by the Southern California Seismic Network and Caltech Seismological Laboratory have…
