Fifteen people were killed and 200 injured in
a strong shock that was felt across Luzon Island.
The earthquake wrecked one multistory building,
a school, and several smaller structures in Manila.
The three-story west wing of an elementary school
in Manila's Chinatown section collapsed into a
heap of rubble no higher than six feet in some places.
This portion of the school had 30 classrooms that
normally accommodated many of the 2,000 students
enrolled. Fortunately, the school was closed as a result
of a transportation strike when the earthquake occurred.
The city's tallest building, the 22-story Manila Hilton
Hotel, had many cracks in its walls,
and chunks of marble and plaster littered the stairwell.
The tremor shook sidewalks and streets so severely
that it was nearly impossible to either walk or drive for
a few moments. Minor aftershocks on April 12 caused some
additional injuries and minor damage.
