The 2019 Batanes earthquake was a magnitude 6.0 earthquake which struck Batanes, Philippines on July 27, 2019. It was preceded by a 5.4 magnitude foreshock. Nine people were killed by the combined effects of the earthquakes.
The main shock of the earthquake was the 6.0 magnitude earthquake which had a depth of focus of 43 kilometers (27 mi). The Philippine Institute of Volcanology and Seismology (PHILVOLCS) earlier recorded the tectonic earthquake as a magnitude 6.4 but later revised their records. [1] [2] The earthquake occurred at 7:38 a.m. (UTC+8) on July 27, 2019, near Itbayat, Batanes. [3]
A noted foreshock [1] of the earthquake was the magnitude 5.4 earthquake which struck the same town at 4:16 a.m. (UTC+8). It had a depth of focus of 12 kilometers (7.5 mi) [4]
One of the stronger aftershocks was a magnitude 5.8 earthquake which occurred at 9:24 a.m. (UTC+8). [5]
According to the PHIVOLCS Earthquake Intensity Scale, the earthquake was most felt in the town of Itbayat, Batanes at Intensity VII while the other towns of the same province reported a lesser intensity; Basco at Intensity V, Sabtang and Ivana at Intensity IV. [5] According to the United States Geological Survey, the earthquake had a maximum intensity of VI or has caused "Strong" shaking according to the Modified Mercalli intensity scale. [6]
