Massive magnitude 7.3 hits southern Qinghai, China

This evening's magnitude 7 quake in China's southern Quinghai Province
This evening's magnitude 7 quake in China's southern Quinghai Province
Following the deadly magnitude 6.0 quake earlier today in the southwestern province of Yunnan, China had another large - actually much larger - earthquake less than 5 hours later:
This time, a magnitude 7.3 earthquake hit in the southern Quinghai province at 2.04 am local time. The epicenter is in a remote, mountainous area and far from larger towns or cities, and hopefully did not cause much damage for this reason.
However, it was felt in over 1000 km distance as user reports arrived through our reporting channel.

China's two large quakes today are not likely directly connected - their epicenters are approx. 500 miles apart, but both are ultimately caused by the enormous tectonic forces at play in the ongoing continental collision between the Indian subcontinent against and underneath Eurasia, creating the Himalayan mountain belts and raising the Tibet plateau.

We truly love working to bring you the latest volcano and earthquake data from around the world. Maintaining our website and our free apps does require, however, considerable time and resources.
We need financing to increase hard- and software capacity as well as support our editor team. We're aiming to achieve uninterrupted service wherever an earthquake or volcano eruption unfolds, and your donations can make it happen! Every donation will be highly appreciated. If you find the information useful and would like to support our team in integrating further features, write great content, and in upgrading our soft- and hardware, please make a donation (PayPal or Online credit card payment).

Planned features:
  • Improved multilanguage support
  • Tsunami alerts
  • Faster responsiveness
Thanks to your past donations, these features have been added recently:
  • Design upgrade
  • Detailed quake stats
  • Additional seismic data sources
