MANILA (UPDATE) - The Metro Rail Transit (MRT3) and the Light Rail Transit (LRT) Line 2 stopped operations for the rest of Monday, while LRT Line 1 temporarily suspended its operations, after a strong quake jolted the capital and nearby areas.

MRT operations director, Engr. Michael Capati, said they have to to check the structural integrity of transit system following a magnitude 6.1 earthquake that struck Luzon Monday afternoon.

Capati said MRT operations were stopped at 5:50 p.m., a move that forced rush-hour passengers on the busy Epifanio delos Santos Avenue to seek other means of transportation.

"Stop operations na po ang MRT as of now. We will no longer resume operations today. We need to check the facility kasi malakas po talaga ang lindol," Capati told dzMM.

"Nag-form na kami ng team to check the facilities, both structures and rails natin. So far, sa power [supply] natin walang problema," he added.

Light Rail Transit Authority (LRTA) spokesperson Hernando Cabrera said LRT-2's operations will also cease operation for the rest of the day.

"LRT2 will no longer resume operations tonight. For the safety of everyone, a more thorough inspection shall be conducted to ensure the integrity of LRT2 structures and systems. LRT2 will resume operations tomorrow at 4:30 in the morning," Cabrera said on Twitter.

The LRT-1's official Twitter account, meanwhile, announced the temporary suspension of the transit system's operations.

"In the interest of passenger safety, LRT-1 is temporarily suspending its operations for the whole line (Roosevelt-Baclaran). We are requesting passengers to remain calm and be mindful of their and their fellow passengers’ safety while disembarking at the stations," read a post on LRT-1's official Twitter account.

"Please standby for advise on resumption of LRT-1 operations in the next few hours."

The tremor struck 18 kilometers northeast of Castillejos, Zambales at a depth of 12 kilometers, Phivolcs said.
