Expert: 100 years before another killer quake in Panay-A A +A
Tuesday, October 22, 2013
IT WILL take about 100 years from 1948 before a giant tremor will hit Panay Island again, an official of the Philippine Institute of Volcanology and Seismology (Phivolcs) said Tuesday.
Ramil Atando, a science research analyst of Phivolcs, said the last killer earthquake that struck Panay Island in 1948 has a magnitude of 8.1. It partly damaged the Jaro belfry in Jaro, Iloilo City and other heritage churches in the province of Iloilo.
Atando said the killer tremor was caused mainly by the moving West Panay fault, which stretches more than 90 kilometers from the municipality of Lambunao in Central Panay to San Joaquin in Southern Iloilo, passing through the municipalities of Alimodian, Leon, Igbaras, Janiuay, and other coastal towns in Iloilo.
The fault line reaches up to the municipalities of Jamindan and Tapaz in Capiz province, and the municipalities of Libacao, Madalag, Ibajay, and Malinao in the province of Aklan, but spares the province of Antique, which belongs to another fault line from the Tablas Strait.
Atando also said Tuesday that the West Panay fault line will not be able to touch the biggest dam project in Panay, the Jalaur River Multi-purpose Project in the municipality of Calinog, Iloilo, as it is located in a safe distance of more than 12 kilometers from the fault line.
As to the heritage sites damaged by the quake, he said the National Historical Institute and Philippine Institute of Civil Engineers have forged an agreement to rehabilitate and repair the old churches.
Iloilo City Mayor Jed Patrick Mabilog, for his part, said that while buildings and structures in the city are stable after the October 15 earthquake in Bohol Island, it is now imperative that the National Government, especially the Tourism Infrastructures Economic Zone Authority, will conduct steel reinforcement of identified old churches built centuries ago without steel bars.
Mabilog said that in his travels abroad, he had seen how the foreign governments care for their old heritage buildings by reinforcing them with steel to protect and preserve the old buildings.
He said there are more than 20 earthquakes everyday in the Philippines, but most of these tremors are unfelt.
