From what I have gathered, the Balyuan Amphitheater collapsed basically due to the following reason: it was in an unfinished state and time ran out on them when the heavy rains came.
Tacloban Mayor Alfred Romualdez has announced plans to rehabilitate the Balyuan Amphitheater in time for its use as the center of activities for the forthcoming city fiesta.
Mayor Romualdez said work would start anytime this month.
