Thursday, 29 June 2017 18:41

At the sound of the alarm, employees of the Department of Science and Technology - Philippine Institute of Volcanology and Seismology (DOST-PHIVOLCS) performed the Duck, Cover, and Hold technique and evacuated the building as they participate in the 2nd quarter Nationwide Simultaneous Earthquake Drill (NSED).

NSED is a quarterly activity organized by the Office of Civil Defense (OCD) that seeks to heighten public awareness and to educate the public on the importance of preparedness against earthquake hazards.

The 2nd quarter NSED ceremonial venue was held in Davao City at Bolton Street along University of Mindanao on June 29, 2017, Thursday at 2:00 PM. DOST Usec. Renato Solidum, Department of National Defense (DND) Usec. Ricardo Jalad, and Davao City Administrator Zulieka Lopez led the ceremonial pressing of the button to indicate the start of the earthquake drill. The drill in Davao City simulated a Magnitude 7.0 earthquake generated by the Central Davao Fault Zone (CDFZ) with the Intensity of PHIVOLCS Earthquake Intensity Scale (PEIS) VIII [Very Destructive]. Barangay residents, students, and owners of business establishments participated in the community-based drill. Different scenarios were performed to showcase response during a strong destructive earthquake.

As the agency mandated to monitor and study earthquakes, DOST-PHIVOLCS pushes for the continued promotion of earthquake awareness and preparedness since it introduced the conduct of earthquake drills in schools way back 2002.

Philippines is a seismically active country with approximately 90 destructive earthquakes and 40 tsunamis recorded in the past 400 years. Strong earthquakes may result to earthquake hazards such as ground shaking, ground rupture, liquefaction, tsunamis, and earthquake-induced landslide. Awareness and preparedness will increase our chances against natural hazards and disasters.

Mati City, Davao Oriental, Philippines, 30 May 2017

The Philippine Institute of Volcanology and Seismology – Department of Science and Technology (PHIVOLCS-DOST) is conducting a series of 1-day seminar-workshops on Earthquake Awareness and Preparedness for Local Government Units (LGUs) and Barangay Officials of Davao Oriental. The seminar-workshop will be held on May 30, 31, and June 1, 2017 at Honey’s Hotel and Restaurant, Mati City.

The province of Davao Oriental was identified as an earthquake and tsunami prone area. It is transected and bounded by active earthquake generators such as the Philippine Fault and the Philippine Trench. The tsunami threat posed to the eastern Philippine archipelago includes both local and distant tsunamis. Large-magnitude earthquakes that also generated a tsunami have occurred in the region.

The one-day seminar-workshop aims to strengthen the province’s awareness about earthquake and tsunami, as well as to help them prepare in case such natural hazards occur in the region. LGUs and Barangay Officials’ role in correct information dissemination will be discussed in the seminar-workshop.

PHIVOLCS, thru the Provincial Government of Davao Oriental, invited participants from the municipalities of Boston, Cateel, Baganga, and Caraga to attend on May 30. Officials from the municipalities of Manay, Tarragona, BanayBanay, and Lupon and municipalities of San Isidro, Governor Generoso, and Mati City are expected to attend the seminar on May 31 and June 1, 2017, respectively.

In addition, PHIVOLCS will conduct a press conference, PHIVOLCS Infosentro, to give update regarding the recent earthquakes at Honey’s Restaurant on May 31, 2017, and on June 1, Usec. Renato Solidum will be the guest speaker in “Kapihan sa Apo View” at Apo View Hotel, Davao City.

Last year, PHIVOLCS conducted a “Teachers’ Training on Communicating Earthquake and Tsunami Hazards” for elementary teachers from the Division of Mati and District of Manay, Division of Davao Oriental last October 12 and 13, 2016 at Honey’s Hotel and Restaurant, Mati City, Davao Oriental.
