Many international IT companies have been affected by the earthquake that hit Wenchuan, Sichuan Province on May 12.

As a result of the 7.8 magnitude earthquake that hit Wenchuan, a county near Chengdu, Microsoft has closed its Chengdu office and asked its employees to work from home.

Nokia says though there were no casualties in its Chengdu office in the earthquake, the condition didn't allow the employees to go to work, so up to 40 staff of its Chengdu office did not work on May 13.

Motorola has more than 400 employees in its Chengdu branch, and due to the earthquake the company didn't open its doors on May 13.
