StEER Releases Event Briefing and Report on Earthquakes in the Philippines and Peru

On April 22, 2019, at approximately 5:37 pm local time, a magnitude 6.1 earthquake with a depth of 10 km struck 18 km northeast of Castillejos in the province of Zambales in the Philippines. StEER released an Event Briefing:

1. to summarize the seismic characteristics of the 22/23 April 2019 Philippines earthquakes

2. to overview damage to buildings and other infrastructure, as well as disruption to the community in terms of downtime and economic losses

3. to summarize key lessons learned.

On Sunday May 26, 2019, a magnitude (Mw) 8.0 earthquake took place in Eastern Perú. The earthquake occurred at 2:41 am local time and was caused by an intermediate-depth normal fault rupture on the Nazca plate at a depth of approximately 110 km. According to official communications, available as of May 29th, the earthquake resulted in 2 fatalities, nearly 30 injuries, one collapsed bridge, 5 affected pedestrian bridges, multiple landslides and affected roads (about 51 km of affected roads), and damage to hundreds of structures including: 39 health centers, 218 school buildings, 15 commercial buildings, 14 churches, including 3 collapses, and more than 600 uninhabitable residential units. For the community of earthquake engineering researchers and practitioners, the multidisciplinary reconnaissance information available right after the event provides an important opportunity to learn from this earthquake, both technically and also from a policy and decision making perspective. As such, this Preliminary Virtual Reconnaissance Report (PVRR):

1. provides a summary of the origin of the event and its main seismological features,

2. presents a summary of ground motions recorded in three countries,

3. summarizes the preliminary reports of damage.
