Several days ago, MGB Region 6 chief geologist Engineer Mae Magarzo told the media said that “only time can tell” when a structure may collapse because of the sinkholes on the island, which is composed of limestone.

“Ang chemical composition ng limestone is calcium carbonate. When it comes in contact with acid, unti-unti siyang matutunaw. Basta may water, lalo na acid rain... That is why we want the carrying capacity of Boracay observed. As you could see in our geohazard map, almost all of the island is highly susceptible,” she said.

“Nakikita naman natin yung mga building natin diyan, bago gawin yan especially yung mga 2nd and 3rd floor, dumaan yan sa test. Requirement yan ng building officials. Since nagstart ang turismo sa Boracay, wala pa akong narinig dito na merong nagcrack na structures or meron bang nag-sag na mga building.”

“While I walking with the team from DENR as they said, these deep wells might be interconnected daw or there are concerns na may mga sinkholes silang nakita. Pero those were presumptive investigation pa, because what they need to know is they really have to go thru all of those identified na may probability na sinkholes sila.”

After that survey, Gelito said they received no information. This latest development, he hopes, would serve as the chance for the local government and the MGB to meet, process the information, make useful recommendations that eventually be cascaded to residents.

“Kami nga mismo taga-rito, hindi namin alam kung ano ang nangyayari. Wala naman kaming balita na may ganoon. Wala rin kaming nakikita sir. Yung key hole nakikita namin pinupuntahan ng mga turista yun. Pero yung ano na yun, wala talaga kaming nakita kahit isa,” said Jun, a paddle board instructor on the island.

For Jed Clark, whose trip to Boracay is the 2nd family vacation in the last three years, it would do well for the MGB to pinpoint the exact location the sinkholes.

For those living on the island, the reports at this point is poor timing. Incomplete and unclear information about the sinkholes may inevitably impact what lies ahead for Boracay.

“Yung future ng isla namin, may mae-enganyo pa ba na pumunta, dahil nga identified na 800 sinkholes nakakatakot po yun. Medyo nangangamba po kami, kasi we don't have experts from our end na magsasabi kung ano ang possibility with these sinkholes,” Gelito laments.

ABS-CBN News has reached out to staff of MGB in Region 6 to request for a copy of the hazard map showing the location of the 815 sinkholes. The request, however, was denied pending the approval of environment secretary.

Bautista said a meeting with the MGB in Region 6 has been tentatively slated for December 21. Until then, residents and local officials can only hope that despite detections of additional sinkholes, the island will continue to recover from the overwhelming challenges it has and is continuing to overcome.
