REPORT ON MAGNITUDE 6.7 SURIGAO CITY EARTHQUAKE

17 February 2017

I. PROFILE OF THE AFFECTED AREA

Surigao City is the capital of the province of Surigao del Norte, located at Northeastern Mindanao and blessed

with abundant natural scenic spots consisting of various arrays of beaches and island hopping destinations

that can cater to different types of adventures, from swimming to snorkeling and scuba diving. Other natural

attractions in the locality consist of mangrove forests, caves for spelunking, lagoons, waterfalls, rock and coral

formations, and many more. It has a total land area of 245.34 km2 which is roughly 1.4% of CARAGA (Region

XIII). According to the 2015 census, it has a population of 154,137 with an annual growth rate of 1.77% over

the period 2010-2015.

Based on the Philippine Statistics Authority (PSA), the CARAGA region has a poverty incidence of 35.3 per

cent and is considered among the poorest in the country. This means that two out of five families in the region

have an income lower than the minimum required to meet their basic food and non-food necessities.

II. SITUATION OVERVIEW

At 10:03 PM on 10 February 2017, Friday, a strong earthquake of magnitude 6.7 shook the island of Mindanao. The epicenter is located 16 km offshore northwest of Surigao City, Surigao Strait at a depth of 10 km. The earthquake was generated by the movement of Surigao segment of the Philippine Fault. Small-magnitude earthquakes followed afterwards, and as of 6:00 am of 17 February 2017, 205 aftershocks have been recorded by the PHIVOLCS seismic monitoring network.

Based on preliminary intensity reports, the strongest ground shaking was felt at PHIVOLCS Earthquake Intensity Scale (PEIS) VII (Destructive) in Surigao City. Furthermore, the municipalities of Pintuyan in Southern Leyte, and San Francisco and Malimono in Surigao del Norte experienced the ground shaking at PEIS VI (Very Strong), while the municipalities of Mainit and Placer in Surigao Del Norte, Libjo and San Jose in Dinagat Island, San Ricardo, Limasawa and San Francisco in Southern Leyte and Manduae City felt the shaking at PEIS V (Strong). This earthquake was felt PEIS IV to I as far as 250 km away (Butuan City, Ormoc City, Tacloban City, Catbalogan City, Bislig City, Cebu City, Cagayan De Oro City, Dumaguete City and Tagbilaran City) from the epicentral area. The strong ground shaking near the epicentral area resulted to damages to some buildings, roads and bridges.

Why do earthquakes occur in Surigao del Norte?

2 Quiapo Church Disaster Preparedness and Response Ministry MAGNITUDE 6.7 SURIGAO EARTHQUAKE

Eastern Mindanao, including Surigao del Norte, is one of the seismically active areas in the country because of the Philippine Fault and Philippine Trench, which are the main earthquake generators that can affect the area. In addition, there are local faults which can be sources of small-to-large-magnitude earthquakes.

Can these present earthquakes indicate volcanic activity?

No. There are no active volcanoes in the epicentral area.

What can we expect from the current earthquake activity?

The current seismic trend indicates that the magnitude 6.7 earthquake on February 10, 2017 is the main shock, which caused the strong ground shaking. The succeeding small-magnitude earthquakes are the aftershocks. The aftershocks may continue to occur for several days to weeks, some of which may be felt. However, the probability of an earthquake higher than 6.7 magnitude to occur is low.

Aside from strong ground shaking, what other seismic hazards are life-threatening?

Landslides, rock falls, and other types of mass movements may occur in mountainous or hilly areas. Liquefaction, manifested by sand boils or lateral spread may affect low-lying, water-logged, sandy areas at the banks of rivers. Tsunami is not expected from the kind of movement of the Philippine Fault-Surigao segment. The tsunami threat for Surigao del Norte would come from the movement of the Philippine Trench, located east of the province.

1. A total of eight (8) persons were reported dead in the province of Surigao del Norte due to the earthquake.

2. A total of 202 persons sustained injuries due to the earthquake and were brought to the hospitals for medical treatment.

C. Damages

A total of 3,257 houses in the province of Surigao del Norte were damaged due to the earthquake, of which 215 are totally damaged while 3,042 are partially damaged

What should be done by the affected communities?

People are reminded to be cautious of structures visibly weakened or with signs of damage by the February 10, 2017 earthquake, as these may be further damaged by aftershocks. In case of houses and other buildings with visible damage, it is best to contact the Municipal/City Engineering Office for advice. Engineers from the local government, other agencies and organizations should inspect buildings and other infrastructures to determine their integrity, and recommend appropriate actions to concerned affected groups or individuals. Slopes should be checked for tension cracks that may have resulted from the strong ground shaking. Tension cracks may make slopes more susceptible to landslides. These areas should be avoided.

4 Quiapo Church Disaster Preparedness and Response Ministry MAGNITUDE 6.7 SURIGAO EARTHQUAKE

The best course of action is preparedness. In case of another felt earthquake, it is recommended that people protect themselves by doing the “duck, cover and hold”. In homes and offices, heavy furniture should be strapped to the walls, and appliances be secured to prevent them from toppling and causing injuries to persons.

SECURITY AND POLITICAL SITUATION

As of February 14, 2014, the New People’s Army declared a unilateral ceasefire for the sake of immediate response by the government towards the far flung affected areas stricken by the 6.7 magnitude earthquake. This will relatively equate to the fast assistance of the affected communities. The Local Government Unit of each municipality is collaborating closely with its various departments working in response to the said disaster.

V. NEEDS ANALYSIS

Health:

Some of the people affected by the earthquake and aftershocks are displaying signs of stress and

trauma and as such require psychosocial support. Staff and volunteers involved in the response will

also require PSS.

Food:

There is a need to provide hot meals for displaced families as many are apprehensive about returning

to their homes and cannot prepare meals.

Shelter:

6 Quiapo Church Disaster Preparedness and Response Ministry MAGNITUDE 6.7 SURIGAO EARTHQUAKE

Over 1,700 houses are reported either damaged and destroyed, leaving the affected families staying in

open areas or tents. There is a need for emergency shelter solutions and essential household items.

Water, Sanitation and Hygiene (WASH):

Water supply has been disrupted by the earthquake. There is a need to mobilize water treatment units

to provide safe drinking water, complemented with distribution of jags for water storage.

Hygiene kits are needed to enable affected people maintain personal hygiene.

Mosquito nets and mosquito repellant lotions are needed to contribute to preventing dengue, especially

since many people are sleeping out the open, including during daytime.

Cash:

The earthquake has disrupted the daily lives of affected people, including opportunities to earn an

income. There is a need for multipurpose cash grants for meeting other immediate household needs,

particularity once markets are functional and accessible.

Cash for work will be implemented by DSWD
