A TOP official of the Philippine Institute of Volcanology and Seismology (Phivolcs) said Zamboanga City has two unmarked fault lines.
Engineer Allan Rommel Labayog, Phivolcs-Zamboanga science research analyst, made the revelation as he urged the local authorities to have the fault lines marked to identify buffer zones and to regulate the development of the area.
Labayog said one of the fault lines is located in the village of Limpapa, 42 kilometers west of Zamboanga City, and the other one is found in the village of Tagasilay, 61.65 kilometers east of the city.
Labayog has urged the City Disaster Risk Reduction Management Office to formally request to Phivolcs Manila to send a geologist who will mark the fault lines.
A fault line is a break or fracture in the ground that occurs when the Earth's tectonic plates move or shift. It is an area where earthquakes are likely to occur. (SunStar Zamboanga)
