BOHOL -- About 2,700 aftershocks have been recorded since the magnitude 7.2 quake devastated parts of Central Visayas last October 15, the National Disaster Risk Reduction and Management Council (NDRRMC) said.
As of 6 a.m. Thursday, more than three million people have been affected by the earthquake, the council said.
Citing data from the Philippine Institute of Volcanology and Seismology (Phivolcs), it said that nine days since the earthquake, 2,654 aftershocks had been recorded.
Of the number, 68 had been felt across several provinces, including Cebu and Bohol.
Meanwhile, the number of people affected by the quake reached 3,158,009 in 1,494 barangays in six provinces.
The earthquake forced 14,740 families or 78,897 individuals to stay in 125 evacuation centers.
The death toll remained at 198, while the number of injured increased to 668.
Damage to property was estimated at P1,426,542,000, including P1.22 billion in Bohol and P197.4 million in Cebu.
In Barangay Caimbang in the town of San Isidro, eight houses were destroyed and 23 families were displaced after the Cimplangon Bridge collapsed.
It wiped out the entire Purok 5, Barangay Councilor Condrado Astronamo said.
The bridge was supposed to connect San Isidro to the neighboring Catigbian town.
“Gituyo man nag pahimo aron maduol mi sa ospital,” said Astronamo.
He said the collapsed bridge is about 500 meters long. It was funded by the Australian Government. The project was finished three days before the quake.
Dionisia Tirol, 75, was alone in her house in Purok 5 when the ground shook at 8:12 a.m. last October 15. The bridge crushed her house.
“Maayo gani giluwas ko sa akong mga bata,” she said.
Astronamo recalled that the bridge did not collapse right away. It caved in after a series of aftershocks.
As of Thursday, Bohol province has incurred a total damage of P1,227,421,000 in infrastructure like hospitals, schools, roads, flood control, bridges and other structures, the NDRRMC reported.
There were 16 casualties in Antequera and eight in San Isidro.
NDRRMC also recorded 19 injuries in Antequera and 90 in San Isidro.
The earthquake damaged 3,248 houses in Antequera and 1,874 in San Isidro. A total of 2,434 families were displaced in San Isidro alone.
Boulders slid from the mountain down to the roads, from San Isidro to the adjacent municipality of Antequera, but the road remained passable.
Antequera Disaster Risk Reduction Management Council officer Januario Lanzaderas said the boulders fell during the earthquake.
He said water supply dwindled after landslides destroyed the pipelines.
In San Isidro, water supply comes from a secondary source in Barangay Causwagan. The water system in Barangay Poblacion failed due to a mechanical defect.
Municipal Councilor Lil Nunag said their tourist attractions like the Mag-aso Falls in Barangay Canjumay was not affected by the quake.
“Several residents told me that the direction of the water had changed,” he said. “But it is still beautiful.”
Pangpangubog Falls, he said, was also spared.
Meanwhile, Nurse Vanessa Sosas of the Department of Health (DOH) said that most of those they treated were children and adults who have cough, fever, hypertension, and diarrhea.
In Antequera, the same illnesses were encountered by government and volunteer doctors, said Lanzaderas.
San Isidro Municipal Hall was wrecked, according to the NDRRMC report, while the Antequera town hall was damaged.
Elementary schools in Ubojam and Danao in Antequera were also damaged.
Meanwhile, Dr. Renato Solidum, Phivolcs director, told Sun.Star Cebu on Thursday the cracks found in the towns of Barangay San Isidro and Antequerra were minor but continuous fissures caused by uneven movement on the ground.
Solidum said the fissures, caused by a phenomenon called lateral spreading, often occur in areas where the soil is loose.
The occurrence of sinkholes and landslides is often attributed to lateral spreading, depending on the ground’s stability.
Solidum said that fissures caused by lateral spreading can even affect man-made structures like bridges, like what happened in San Isidro where a bridge collapsed.
But Solidum said residents should not fear signs of lateral spreading as these can easily be fixed by filling them with solid materials. (Sunnex)
