DOST-PHIVOLCS Media Advisory for the upcoming 50th Commemoration of the 1968 Casiguran Earthquake. A symposium and exhibit on August 2, 2018 at Minor Basilica of Black Nazarene (Quiapo Church), Manila will be conducted. This event will promote geologic hazards awareness and disaster risk reduction and management through DOST-PHIVOLCS information products, and encourage a culture of disaster resilience in the community.

The Department of Science and Technology-Philippine Institute of Volcanology and Seismology (DOST-PHIVOLCS) commemorates the 1968 Casiguran Earthquake on its 50th year this August 2, 2018.

A magnitude 7.3 earthquake struck the town of Casiguran, Aurora on August 2, 1968 at 4:19 AM (PST). The earthquake caused large fissures with lengths measuring from 10 to 20 meters but in some areas, it reached a length of 400 to 500 meters. Fissures on the road from Casiguran to Barrio Tabas produced a surface subsidence up to two meters. Landslides were observed in the mountainous area near the epicenter and tsunami was recorded according to the observation in tide gauge station in Japan.

Rossi-Forel Earthquake Intensity VII was recorded in Manila in spite of its location being far from the epicenter. The Ruby Tower, a six-storey building in Binondo, Manila, collapsed instantly during the quake killing 268 people. Several buildings such as Aloha Theater, Philippine Bar Association Building, National Library, and Liwayway Hotel in Manila sustained varying levels of structural damages. The 1968 Casiguran Earthquake is said to be one of the most destructive earthquakes in the Philippines.

This event paved the way for the establishment of the National Committee on Disaster Operations (NCDO) under the Administrative Order No. 151 on December 2, 1968. Republic Act 6541, An Act to Ordain and Institute a National Building Code of the Philippines was also enacted in 1972.

On the 50th year of the 1968 Casiguran Earthquake, PHIVOLCS will be conducting a symposium and exhibit on August 2, 2018 at Minor Basilica of Black Nazarene (Quiapo Church), Manila.

PHIVOLCS encourages everyone to look back and remember not only the tragedy, but also the lessons we learned. Let us keep our communities safe from and resilient to natural hazards and disasters.

The Department of Science and Technology - Philippine Institute of Volcanology and Seismology (DOST-PHIVOLCS) aims to train teachers on basic information about the science of earthquake and tsunami and its hazards, preparedness, and how to communicate this information to their students through a one-day “Teachers’ Training on Communicating Earthquake and Tsunami Hazards” for elementary school teachers of Ormoc City.

In coordination with the Department of Education (DepEd) and the local government of Ormoc City, two batches from the public and private elementary teachers from 95 schools and staff from Ormoc City Disaster Risk Reduction and Management Office will attend the training on July 4 & 5, 2018 at Pongos Hotel, Ormoc City, Leyte.

The training intends to capacitate teachers to provide school children with the right information to prepare, respond and protect oneself in the event of an earthquake or tsunami. The program highlights the use of DOST-PHIVOLCS teaching aids, “Ahh..Ngayon Alam Ko Na” and “11 Mga Dapat Gawin Kapag May Lindol”. The flashcard “11 Mga Dapat Gawin Kapag May Lindol” features a sign language guide for the hearing impaired. These flashcards are adapted from materials developed by Arbeiter-Samariter-Bund Deutschalnd (ASB).

Earlier this year, DOST-PHIVOLCS conducted three-day training on Communicating Volcano, Earthquake, and Tsunami Hazards for 28 high school teachers and school disaster risk reduction focal person/coordinator last April 24-26, 2018 at Pongos Hotel, Ormoc City, Leyte.

To aid in disaster preparedness of Metro Cebu, the Department of Science and Technology – Philippine Institute of Volcanology and Seismology (DOST – PHIVOLCS) will launch the Metro Cebu Earthquake Model (MCEM) Atlas on July 4, 2018 at the DepEd Ecotech Center, Ecotech Rd., Sudlon, Lahug, Cebu City.

The Atlas is a seismic ground motion hazard assessment specific for Metro Cebu, considering various earthquake sources including the Central Cebu Fault System. This Atlas may be used as reference in the seismic design of buildings and structures and as a tool for earthquake impact assessment and earthquake risk reduction efforts of national government agencies, Local Government Units (LGUs) in Metro Cebu, academe and the private sector.

Metro Cebu, a fast-growing and dynamic metropolis, has been identified as an earthquake-prone area. The Central Cebu Fault System transects Danao City, Compostela, Cebu City, Talisay City, Minglanilla, Naga City, Balamban and Toledo City. Large-magnitude earthquakes have occurred in the region. The MCEM Atlas aims to minimize the damages to buildings and infrastructures in case a strong earthquake hits the area.

This Atlas contains Peak Ground Acceleration (PGA) and Spectral Acceleration (SA) maps, which were modelled using Probabilistic Seismic Hazard Analysis (PSHA) through the collaborative efforts and expertise of seismologists, geologists, engineers and researchers from DOST – PHIVOLCS in consultation with various stakeholders such as the Provincial Disaster Risk Reduction Management Office (PDRRMO), the regional offices of the Office of Civil Defense (OCD), the Department of Science and Technology (DOST), the Department of Public Works and Highways (DPWH), the Department of Interior and Local Government (DILG) and the National Economic and Development Authority (NEDA). It was also participated by Ramon Aboitiz Foundation Inc. from the private sector, Cebu Institute of Technology – University (CIT-U) and University of San Jose – Recoletos from the academe and by representatives of Local Government Units (LGUs) that comprise Metro Cebu. Also included in the Atlas are the Seismicity Map of Metro Cebu and Vicinity, the Distribution of Active Faults in Region VII and the Metropolitan Cebu Vs30 Site Model.

Earlier this year, DOST – PHIVOLCS launched the Philippine Earthquake Model (PEM) Atlas which covers the whole Philippines, and Metro Manila.

Copies of MCEM Atlas will be distributed during the event. Stakeholders can also download the digital copy online from DOST – PHIVOLCS official website (www.phivolcs.dost.gov.ph).
