The tremor was centered in the Gran Pajonal (Satipo)
area near the location of the destructive earthquake
that killed 233 residents on November 1, 1947.
Although no fatalities resulted from this earthquake,
a state of local emergency was declared in Huancayo,
where many houses were damaged, water supplies were cut
off, and numerous roads were blocked by landslides.
The highways leading to Huaytapallana were almost
completely erased, and several bridges collapsed.
Flooding resulted from this earthquake. In the
Huaytapallana glacier area, the Chuspi and Asuntay snowpeaks
collapsed, causing Asuntay lake and the Shullcas River to
inundate nearby areas. Severe damage was caused by the
Shullcas River, which rose more than 5 meters (16 feet).
The earthquake also caused cracks in the control gate
of the dam at Lake Asuntay. Bridges and roads were
washed out between Huancayo and Chilifruta, and damage
was reported from several surrounding towns.
