8 km WNW of Changning, China
Geographic Context
This earthquake event occurred near Changning (approximately 8 km away) in China, located within a complex tectonic setting influenced by the India-Eurasia collision. An estimated 54.3K people live within 20 km of the event location, placing this in the "significant" population impact tier.
Event Assessment
This event is a moderate earthquake measuring 5.2 on the magnitude scale, with a focal depth of 10 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 41.6. The computed Calamity Score is 34 out of 100, suggesting contained impact at this time. The primary scoring components are: historical (80), population (55), intensity (24). Data for this event was sourced from usgs, one of the 250 scientific monitoring sources aggregated by Calamity.live.
Regional Monitoring Context
China 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.
