A magnitude 3.1 earthquake struck the province of Southern Leyte on Thursday, according to Philippine Institute of Volcanology and Seismology (Phivolcs).
In its bulletin, Phivolcs said the epicenter of the tremor, which happened at 1:55 a.m., was traced 10 kilometers southeast of Limasawa in Southern Leyte.
The agency said the quake was felt at Intensity 2 in San Juan, Southern Leyte.
Phivolcs said there was no damage or casualty reported from the tremor and no aftershocks were expected.
Meanwhile, science research specialist Ric Mangao of the Phivolcs’ Earthquake Monitoring Division said that at least seven aftershocks have already struck Quezon province since it was jolted by a magnitude of 5.5 earthquake Wednesday evening.
In an interview, Mangao said the series of quakes were recorded from the time the “main quake” occurred up to 2 p.m. Thursday.
Mangao said these aftershocks, which were measured between magnitude 1.8 and 3.4, were all unfelt.
At 9:43 p.m. Wednesday, a magnitude-5.5 temblor hit Quezon and traced the quake’s epicenter at 48 kilometers northeast of Jomalig town in Quezon, which felt the tremor at Intensity 4.
The towns of Patnanungan, Panukulan, and Polillo in Quezon also felt the quake at Intensity 4.
Intensity 3, on the other hand, was recorded in Calauag, Infanta, General Nakar, Mauban, and Guinayangan in Quezon; Gapan and Gabaldon in Nueva Ecija; Quezon City; Mandaluyong City; Antipolo City; Marikina City; Cainta, Montalban, and San Mateo, Rizal; Malolos and Obando, Bulacan; as well as in Daet and Jose Panganiban in Camarines Norte.
Intensity 2 was monitored in Real, Unisan, Lucban, and Sampaloc, Quezon; Baler and Maria Aurora in Aurora; Sta. Rosa and Sta. Cruz in Laguna; Tanza, Cavite; Makati City; Muntinlupa City; Taguig City; Malabon City; Pasay City; and Lucena City, while Baguio City felt the tremor at Intensity 1.
Phivolcs noted that no damage was reported from this quake, but aftershocks were expected.
Mangao said that aftershocks may continue to prevail in the province in the coming days.
However, he noted that many of these aftershocks would be with weaker magnitude.
Mangao said it was likely that movements along the Philippine Trench caused these tremors.
The Philippine Trench is located underwater east of the country that runs roughly from waters off Aurora down to Samar, and past Mindanao. PNA
