Yunnan Earthquake Agency explained why no warning information was received after the 7.9-magnitude earthquake in Myanmar on their Sina Weibo account on Friday, saying the quake was approximately 300 kilometers from the nearest warning station in China. There are no earthquake warning stations networked outside the country.

According to the agency, its earthquake early warning system is capable of providing information on earthquakes of magnitude 4.0 and above within a range of 50 kilometers around Yunnan province.

This situation exceeds the current response capability of the earthquake early warning system; hence, no warning signal was issued, it said.

A 7.9-magnitude earthquake rocked Myanmar at 2:20 pm on Friday, as reported by the China Earthquake Networks Center. The earthquake's epicenter was at a depth of 30 kilometers. Seismic waves reverberated across multiple regions in Southwest China, particularly Yunnan province.
