Mount Clark continues to be wracked by increasingly violent eruptions as the YUNYA moves into the eastern coast of Luzon , Philippine Islands . The two forces of nature threaten to engulf cities and towns in their path . Temperatures of rivers were rising due to hot ash . Debris was clogging everything except generators , thus disrupting power supplies . Pinatubo began erupting violently on Friday and these explosions are seen as a single eruption . ; Foreign Secretary Raul Manglapus also said the eruption should have no effect on talks on the future of Clark and Subic, where leases expire Sept. 16. The eruption is occurring at the same time as U.S.- Philippine discussions on a military bases treaty . It could remain active for months , possibly rendering Clark inoperable .
