MANILA, Philippines – More than 90 aftershocks have already been recorded in Zamboanga del Norte since a strong earthquake jolted the province before dawn Thursday, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).
As of 1 p.m. Sunday, Anna Shellah Mae Enbien, science research assistant of the Phivolcs’ Earthquake Monitoring Division, said they have already recorded a total of 94 aftershocks.
Enbien noted that the aftershocks were all unfelt since the magnitudes were small.
On Thursday, a magnitude 6.0 quake rocked Zamboanga del Norte and nearby areas at 2:21 a.m.
The epicenter of the tremor was traced 19 kilometers northwest of Baliguian town in Zamboanga del Norte.
The quake, which was tectonic in origin, had a shallow depth of 16 kilometers.
At least three persons were reported hurt after four houses at Brgy. Sinunuc in Zamboanga City collapsed due to the strong temblor.
Residents of Zamboanga City experienced the strongest shaking at Intensity 6, while the municipalities of Baliguian and Siocon in Zamboanga Del Norte felt it at Intensity 5.
While the aftershocks may continue for a month, Enbien said it should not be a cause of panic since it will be of less magnitude as days pass by.
She reiterated that movements from an offshore fault in Zamboanga Del Norte possibly triggered these temblors.
