What was the epicenter of the earthquake that occured in China on May 12?


I have a Social Sciences project for Friday, and I just can't seem to find info. about this quake. Any other information you could give is appreciated!

Magnitude 7.9 - EASTERN SICHUAN, CHINA

The 2008 Sichuan earthquake (Chinese: 四川大地震), which measured at 8.0 Ms according to the China Seismological Bureau, and 7.9 Mw according to USGS, occurred at 14:28:01.42 CST (06:28:01.42 UTC) on 12 May 2008 in Sichuan province of China. It was also known as Wenchuan earthquake (Chinese: 汶川大地震), after the earthquake's epicenter in Wenchuan County in Sichuan province. The epicenter was 80 kilometres (50 mi) west-northwest of Chengdu, the capital of Sichuan, with a depth of 19 kilometres (12 mi).[2] The earthquake was felt as far away as Beijing (1,500 km away) and Shanghai (1,700 km away), where office buildings swayed with the tremor.[5] The earthquake was also felt in nearby countries.

Official figures (as of May 21, 12:00 CST) state that 41,353 are confirmed dead, including 40,854 in Sichuan province, and 274,683 injured.[4] The Chinese government warned that the death toll could reach 50,000.[6] Tens of thousands are missing, approximately 14,000 of them buried, and eight provinces were affected.[7] The earthquake left about 4.8 million people homeless.[8] It was the deadliest and strongest earthquake to hit China since the 1976 Tangshan earthquake, which killed over 240,000 people.

A seismograph station is located 2000 km from an earthquake’s epicenter. Explain the order that the S and P waves will arrive at the station. Using what you know about the characteristics of the different waves, explain your answer.

The P waves vibrate very quickly out from the epicenter first in all directions, in a circular manner passing the station.

The S waves then vibrate out from the epicenter a few seconds later and cause the sideways shaking of the land as they pass the station.

The P wave then reflects off the core of the Earth and bounces back past the station, followed by the S wave a few seconds later as both waves reflect off the earths core back to the epicenter (origin)
