Lucena City - After a swarm of earthquakes rocked parts of Southern Luzon on Saturday, more than 5,500 individuals were evacuated in different towns in Batangas province, a disaster official in the Cavite, Laguna, Batangas, Rizal, Quezon (Calabarzon) region said Sunday.
Gianan pointed out that Phivolcs is still verifying if Saturday's earthquakes are separate events, and not aftershocks, since they are stronger than last Tuesday's 5.5-magnitude tremor that hit Tingloy, Batangas.
The quakes about 90km south of the capital Manila occurred over a period of about 20 minutes, said the USGS.
In Manila, people were also seen running out of office buildings.
AFP reporters saw people running out of office buildings in Manila's financial district, while local television network ABS-CBN broadcast live footage of frightened commuters fleeing the passenger terminal at the port of Batangas, near the epicentres.
Major damage was reported at the Mabini General Hospital while the Anilao Market also in Mabini town suffered structural damages.
The strongest quake is reported to be at a depth of 27 miles (43km).More news: Elon Musk's SpaceX launches recycled rocket in historic first
"It would be best if they will just stay inside their homes".
After the series of quakes, Batangas Gov. Hermilando Mandanas said Batangas City, Bauan, and Mabini were left without electricity. "We are still observing the situation after the natural disaster since there are still aftershocks", PCG spokesman Commander Armand Balilo said.
Taal Mayor Fulgencio "Pong" Mercado said the quake rendered a bigger damage on the 400-year-old church, with a crack also visible in its right canopy.
Phivolcs said Intensity 5 was documented in Batangas City, Sto. The quake was felt the strongest in Mabini at intensity 7.
"We are also monitoring the Taal Volcano".
In Quezon, Provincial Disaster Risk Reduction Action Officer Henry Buzar said the province felt a 2.8 magnitude shaker at 3:09 p.m., 2.9 magnitude at 3:10 p.m. and 2.7 magnitude at 3:11 p.m.
Kristofferson Vidad, a science research assistant at Phivolcs, said that as of 8 a.m. yesterday, 983 aftershocks from Tuesday's quake have been recorded.
