Strange Sounds

This is major!!! Within just 4 hours, a M7.3 and a M6.1 powerfully shook China…The strongest quake, a magnitude 7.4 earthquake, hit on May 21, 2021, 18:04:15 UTC at a depth of 10 km (6.3 miles).

According to my calculations, the estimated released energy is about 7.9 x 1015 joules (2206 gigawatt hours). This is equivalent to 1.9 x 106 tons of TNT or 118.7 atomic bombs!

More than 1.5 million people live in nearby towns and cities:

381 km (237 mi) WSW of Hong Ya (pop: 256)
388 km (241 mi) SW of Xining (pop: 767,500)
397 km (247 mi) NNE of Chamdo (Tibet) (pop: 86,300)
539 km (335 mi) SW of Wuwei (Gansu) (pop: 493,100)
559 km (347 mi) SW of Jinchang (Gansu) (pop: 144,400)

At least 10 aftershocks have rattled the region following the main quake with magnitudes ranging from M3.3 to M4.5.

Here some videos:
