Geographic Context
This earthquake event occurred near Coos Bay (approximately 225 km away) in United States, located in a region with varying seismic hazard profiles across different geological provinces.
Event Assessment
This event is a moderate earthquake measuring 5.5 on the magnitude scale, with a focal depth of 9 km. Events of this magnitude are typically felt over a wide area and may cause damage to vulnerable structures. Calamity.live has classified it as "medium" severity with a severity value of 44. The computed Calamity Score is 20 out of 100, suggesting contained impact at this time. The primary scoring components are: historical (80), intensity (30). Data for this event was sourced from ingv, one of the 250 scientific monitoring sources aggregated by Calamity.live.
Regional Monitoring Context
United States has a documented history of earthquake events. Seismic monitoring in the region draws on data from multiple agencies including USGS, EMSC, and regional networks. Understanding local seismicity helps emergency management agencies plan for potential future events and assess building code adequacy. Earthquake hazard in any region depends on fault proximity, soil conditions, and building vulnerability — factors that can vary significantly even within a single metropolitan area.

Safety Information
If you feel shaking: Drop, Cover, and Hold On. Move away from windows, heavy objects, and exterior walls. After shaking stops, check for injuries and structural damage. Be prepared for aftershocks, which can occur minutes to months after the mainshock. Follow instructions from local emergency management authorities.
