A magnitude 6.4 earthquake struck central Mindanao in the southern Philippines on Wednesday, opening cracks in some buildings, sending residents running from shops and offices and knocking out power.

There were no immediate reports of casualties from the earthquake, which also shook Davao City, the hometown of President Rodrigo Duterte and among the most populous cities in the country.

“We felt a very strong jolt and there was a blackout. I saw people rushing down. We were panicking, heading to the exit,” said Naru Guarda Cabaddu, a hotel consultant visiting Kidapawan City, between the epicentre of the quake and Davao.

“So far, we are on rapid assessment mode. There’s no major damage based on initial report,” Kidapawan City Mayor Joseph Evangelista told.
