Event facts
Estimated shaking · MMI VIII
Severe. Damage considerable in ordinary buildings, including partial collapse. Heavy furniture overturned.
MMI is the Modified Mercalli Intensity scale — what people actually feel. This estimate is derived from magnitude alone; real shaking varies with depth, distance and local soil. The official USGS ShakeMap is the authoritative source.
What an M5.1 feels like
Moderate earthquake. Felt by nearly everyone outdoors. Sleeping people awakened. Dishes, windows, doors disturbed; some objects overturned.
Slight damage to weak structures near the epicenter. Well-built buildings unaffected. Localised falling-debris hazard.
What a deep depth means
Deep earthquakes (over 300 km) occur within subducting tectonic slabs. They can be felt over very large areas but rarely cause surface damage — energy spreads out by the time it reaches the surface.
Energy released
This earthquake released roughly 2.82e+12 joules of seismic energy — about 44.74 thousandths of a Hiroshima bomb.
Caveat: bomb energy is concentrated at a single point in microseconds; seismic energy radiates outward through Earth's crust over many seconds. The comparison is for relative scale only.
