Despite the strong earthquake, the power supply in Luzon remained normal, according to the National Grid Corporation of the Philippines (NGCP).

The Luzon grid remained intact, as there were no reported power interruptions or damage to transmission lines following the quake.

As a result of the tremor, the Philippine National Railways (PNR) temporarily suspended all of its trips on Wednesday.

"Pansamantalang suspendido ang lahat ng mga biyahe ng PNR dahil sa lindol. Maraming salamat po sa inyong pang-unawa," the company said in its advisory.
