UPDATE 13:04 UTC : Since we started this site in August 2010, we have (unfortunately) been writing a lot about Yunnan earthquakes, even one with a deadly outcome. Here are the links to some of our articles. You will immediately see that the magnitudes are sometimes limited, but the damage unevenly big.
* Earthquake Tengchong, Yunnan, China : 2,079 households affected and 6 people injured (3 seriously) (June 20 2011)
* Deaths and injuries from very dangerous earthquake in Yingjiang, Yunnan, China (March 10 2011)
* Very dangerous earthquake below the China / Myanmar border area (February 1 2011)
* Very damaging earthquake “ 8,017 homes on the Myanmar / China border (January 1 2011)
* China “ Magnitude 5.0 earthquake injures 14 people and damages 7,354 houses (August 29 2010)
UPDATE 12:49 UTC : An aftershock of M 3.1 at a depth of 11 km has occurred 28 minutes after the mainshock.
UPDATE 12:48 UTC : The Chinese values which we trust a lot, are reinforcing the dangerous aspect of this earthquake.
UPDATE 12:38 UTC : As the USGS data we have published has been measured a huge distance from China, we always want to give the data of the other seismological agencies as the real values are of an extreme importance for these kind of earthquakes.
GFZ : 5.1 @ a depth of 10 km
EMSC : 5.0 @ 10 km
Chinese seismological agency : 5.2 @ 11 km
Dangerous shallow earthquake in an unstable area who had a lot of misery caused by earthquakes since the end of last year. Earthquake’s epicenter is close to Shangyingxiang and Zhubapu.
Due to the specific terrain in the area, even moderate earthquakes like this one are creating a lot of damage and even injured people.
“I Have Felt It” reports
MMI values (if indicated) after the text (III: Weak shaking, IV Light shaking, V Moderate shaking, VI Strong shaking, VII Very Strong shaking)
China, Yunnan Province, Luxi City (Mang Shi) – (ER: Luxi city is about 60 km from the epicenter) : About 7:55pm, 2011/08/09 local time. Felt computer table start shaking, followed by building moving. Was first experience in an earthquake; my roommates and I left the building, but no further tremors felt. Roommates heard doors shaking, and they wondered what I was doing; when I felt table shaking, I thought they were banging on wall. Obviously, it wasn’t very strong. Friend in a higher apartment building said it shook considerably. No panic among local people, though. – IV MMI
