Mines and Geo-sciences Bureau (MGB) Geologist refused to
approve the return of residents in Magpantay, Sitio Pano-ulan, Barangay
Guadalupe after the site investigation on February 25, Saturday.
MGB's Dr.
Leilanie Suerte and Joel Villanueva arrived in San Carlos following request
from the San Carlos City Disaster Risk Reduction and Management Council
(SCCDRRMC) to conduct an investigation on a crack that appeared on the mountain
of Magpantay.
No threat
Suerte
together with Seismologist Noelynna T. Ramos of the University of
Philippines-National Institute of Geological Sciences (UP-NIGS) concluded that
the crack is not the real threat to the residents of about 40 families. The
crack was only caused by vertical displacement, is less than a meter deep, and
only affects the top soil.
Steep climb.
Dr. Leilanie Suerte of the Mines & Geo-Sciences Bureau inspects the mountain
of Magpantay and discovers lose boulders are more threatening than the crack.

Landslide zone
However,
numerous lose boulders (basalt, volcanic rocks) were found on the gully (steep
slope that acts as the natural passage of water from the mountain top) which
when eroded will sweep houses on its way downhill.
"Given
the right combination of factors such as earthquake and heavy rain, a landslide
could take place," Suerte explained.
The area
is now considered a landslide danger zone and residents are advised not to stay
in their houses at night especially during rainy days.
Recommendations
Other
recommendations include that if the residents should go back, rescuers be
assigned for 24-hr, seven-day shift to alarm them should a landslide take
place. Disaster and evacuation training and drills should also be given to
residents emphasizing when and how to evacuate and where to go.
But the
permanent and best solution, Suerte offered, is relocating the community at
least one kilometer away from the buffer zone at the foot of the mountain where
lose boulders (debris from Mt. Canlaon after it erupted hundreds of years ago)
are likely to fall.
What does the future hold?
Mateo Casipong, 54, left in photo, reflects on
what the future holds for him and his family as their area is now declared a
danger zone. Alingasa, right, told NRWP that there is no regret on evacuating
the residents to a nearby elementary school.
The
geologist, who also conducted inspections in several Isabela and La Castellana
barangays on crack reports, found that the mountain is an underground water
source. One hand-span from the top, its soil is wet despite three days without
rain prior to the MGB's visit. This makes the soil soft and unable to keep
boulders in place. Some boulders as large as two meters in diameter (estimates)
are found directly at the back of houses of light materials.
Voluntary evacuation
Remedios
Casipong, 54, a resident, said her brother-in-law, Romy Casipong, first noticed
the crack at roughly 270 m above sea level. On February 16, the families
started evacuating as Barangay Guadalupe and Negros Oriental continue to feel
the aftershocks of the tectonic earthquake last February 6.
SCCDRRMC
Action Officer Joe Recalix Alingasa said a community discussion will be
conducted soon with Guadalupe Barangay Captain Godofredo Salimbaga.
Based on
initial reports, the residents are farmers working on sugarcane fields
supposedly owned by the Magpantay Family. But Mayor Gerardo Valmayor, Alingasa
related, has ordered the City Assessor's Office to double check if the said
family still legally owns the land.
Although
some personnel of the City Engineering Office questioned the early pre-emptive
evacuation of Magpantay residents despite the lack of advisory from MGB,
SCCDRRMC maintained that the precaution was valid and the threat to people's
lives was eminent as confirmed now by the findings of Suerte, Ramos and
Villanueva.
Suerte
said she will officially report her findings to MGB Regional Office VI so that
an official evacuation order will be properly channeled.
As
residents brace their future relocation, they are temporarily staying at
Panoulan Elementary School while their male workers go back to their farms at
daytime to till the land and feed livestock.
