The Structural Extreme Events Reconnaissance (StEER) Network has issued an Event Briefing for the June 17, M6.0 earthquake in Sichuan, China.  Event Briefings  are typically released within 48 hours of an event for which StEER will not deploy virtual or field assessment teams, but still warrants some commentary. This briefing summarizes the event characteristics and key lessons learned.
