US Earthquakes and Geological Hazards This Week: USGS Tracks Seismic Activity and New Discoveries

Across the United States this week, geologists are tracking a mix of quiet hazards and new discoveries that shed light on how the planet is changing beneath our feet. The United States Geological Survey reports that nationwide seismicity remains within normal ranges, with hundreds of mostly small earthquakes over the past seven days, concentrated in Alaska, Hawaii, California, and other parts of the Pacific Ring of Fire. According to the United States Geological Survey earthquake map, no large, damaging earthquakes have struck the continental United States in the last week, but swarms of tiny events continue in southern Alaska and around Pahala on the Island of Hawaii, underscoring the ongoing movement of tectonic plates and magma deep underground. In the realm of hazards research, the United States Geological Survey ShakeAlert team continues to refine the earthquake early warning system for the West Coast, issuing test alerts based on recent small to moderate events in California and the Pacific Northwest, and stressing that even magnitude four earthquakes provide important data for improving warning times. The United States Geological Survey Natural Hazards program is also highlighting new flood and landslide assessments following heavy summer rains in parts of the central and eastern United States, work that ties surface processes such as erosion and sediment transport to community risk. On the discovery side, Science Daily and Sci News report new geology studies that use ancient sediment cores from the Atlantic margin off the eastern United States to reconstruct rapid sea level and climate shifts during past warm periods, providing an analog for modern coastal change. Other research featured by Science Daily describes high resolution imaging of faults beneath the western United States that reveals previously unmapped splay faults, which could influence shaking patterns in future earthquakes. Worldwide, global disaster monitors such as the Global Disaster Awareness and Coordination System list a string of moderate to strong earthquakes in Japan, Indonesia, Chile, and the Fiji region over the past week, as well as continued activity at Italy’s Mount Etna and several volcanoes in Indonesia and the Philippines. These events fit an emerging pattern that geologists emphasize again and again, the planet’s most intense geologic activity remains focused along plate boundaries, but its consequences, from tsunamis to ash clouds and supply chain disruption, are felt far beyond the immediate fault or volcano.
