A magnitude 4.5 earthquake, which was followed by two strong aftershocks in minutes, rocked the town of San Joaquin, Iloilo province on Friday morning, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
In an interview with The Manila Times, Phivolcs chief Renato Solidum said the epicenter was located 14 kilometers southwest of San Joaquin at 8:27 a.m.
Some five minutes later, a 4.4 aftershock was recorded in the same town and nine minutes later, another 4.4 aftershock was reported also in San Joaquin, said the Phivolcs chief.
With a depth of 6 kilometers, the quake was tectonic in origin, added Solidum.
He said Intensity 4 was recorded in Miagao, Iloilo while Intensity 3 was reported in the towns of Aniniy and Hamtic in Antique.
Meanwhile, Intensity 2 was reported in Bago City and Sipalay City in Negros Occidental and San Jose de Buenavista, Antique; and Intensity 1 in Iloilo City and Valderama, Antique.
Saying the quake would not cause a tsunami, Solidum added that damage was unlikely but aftershocks may occur.
