"According to a China News Services (CNS) report on May 31, 2008, paramedics from People's Liberation Army (PLA) hospitals and psychologists from Beijing onsite May 23 found concrete debris at the bottom of a valley near the epicenter. The half-mile-wide valley was covered with debris 10 - 20 inches thick, covering the valley floor for almost 1.5 miles'
"Based on the CNS report and timing of the eruption at the scene, there seemed to be no evidence of natural volcanic activity. The expert stated he was certain a nuclear explosion shattered the underground concrete structures, hurling debris into the air."
"Chinese Internet surfers commented that right after the quake military Special Forces blocked traffic heading toward the epicenter on the mountain, and men in white chemical protective clothing in military vehicles were also spotted driving toward the mountain. Rescue personnel near the epicenter were all military, according to witnesses."
