made it appear as through it was nighttime during the middle of the day, prompting concern from residents. The wind from the typhoon carried ash within from Pinatubo, including to Manila, which prompted most of the airports in the country to close and Philippine Airlines to cancel all domestic and international flights through June 19. Low to mid-level winds and heavy rains from the storm contributed to widespread tephra falling over an area of of central and western Luzon. Heavy rains also resulted in lahars along mountains between the Gumain River to the Sacobia River and between Sacobia River to the O'Donnell River. These lahars inundated crops and homes, especially along the Abacan River. As a result of the lahars, some buildings and all bridges in Angeles City were destroyed. Moreover, 320 people were killed and 279 others were injured. The United States Geological Survey believes that the death toll from the lahars would have been far lower if not for Yunya. In addition to the lahars, widespread flooding also took place in Luzon as rivers overtopped their banks. Elsewhere, a person was killed by debris in Manila. Across Olongapo City, power was knocked out, and one person was killed after the roof of a bus terminal collapsed under the weight of ash and rain. Two people died and three others were injured in an accident near Clark Air Base, where power was also knocked out. Along the Sacobia River in Pampanga, at least 170 homes were washed away due to the storm. The Abacan bridge spanning the Abacan River collapsed with a truck carrying three people, and an empty car. It is unknown whether the three people survived. A total of 2 people were killed and at least 12 warranted evacuation in Angeles City when the roof of a bus terminal, where 100 people were riding out the storm, operated by Philippine Rabbit Bus Lines collapsed. Civil defense officials confirmed that five other bridges collapsed in Pampanga and Zambales provinces. All crops were destroyed throughout Iriga. Overall, 2,013 homes were destroyed and 24 others were damaged during the passage of the typhoon. A total of 2,035 families or 10,185 people were evacuated to shelters. Excluding from lahars, six people were killed by Yunya.
