Two magnitude-5.2 earthquakes struck Liuzhou in the Guangxi Zhuang Autonomous Region on May 18 [1], [2].
The rare sequence of twin tremors caused building collapses and forced the mass evacuation of residents in southwest China. The event highlights the vulnerability of urban infrastructure in the region to sudden seismic activity.
Emergency responders said two people died [3] and one person remains missing [4] following the tremors. The two earthquakes occurred within less than 24 hours of each other [2], [5].
Local authorities coordinated the evacuation of more than 7,000 residents [3] to ensure public safety as rescue teams searched through debris. The tremors caused significant structural damage to several buildings in the city [2], [5].
Officials said they are currently investigating the tectonic activity that led to this unusual sequence of events [5]. While some reports initially cited a single quake, multiple sources confirmed two distinct magnitude-5.2 events [1], [2].
Rescue operations continued throughout the day as teams worked to locate the missing individual [4]. The Guangxi Zhuang Autonomous Region has seen varying levels of seismic activity, but the occurrence of two nearly identical magnitude events in a single day is considered uncommon by regional observers [5].
“Two magnitude-5.2 earthquakes struck Liuzhou in the Guangxi Zhuang Autonomous Region on May 18.”
The occurrence of two earthquakes of the same magnitude within a 24-hour window suggests a complex seismic trigger or a series of closely linked aftershocks. Because Liuzhou is a major industrial hub, the evacuation of thousands of people and the collapse of buildings underscore the necessity for updated seismic building codes in the Guangxi region to mitigate future casualties.
