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 M5.5 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 intermediate depth means
Intermediate-depth events (70–300 km) attenuate more before reaching the surface, so a given magnitude is typically felt over a wider but weaker area than a shallow quake of the same size.
Energy released
This earthquake released roughly 1.12e+13 joules of seismic energy — about 178.10 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.
