As of 4:43 p.m., Phivolcs reported the same earthquake intensities as the first one.
A third magnitude-4.1 tremor was recorded at 3:29 p.m. 2 kilometers northwest of San Luis, Batangas.
Meanwhile, the United States Global Survey (USGS) also reported three earthquakes.
A magnitude-5.5 quake in Bagalangit, Mabini, Batangas was recorded at 3:08 p.m., while a stronger magnitude-5.9 tremor was recorded shortly after in Talaga, Tanauan, Batangas.
USGS added a third magnitude 5.0 earthquake hit Taysan, Batangas at 3:29 p.m.
Shortly after the quakes, Batangas Governor Hermilando Mandanas told CNN Philippines there was no electricity in Batangas City, Bauan, and Mabini.
He added so far, only minor damages have been reported and no evacuations have taken place, but they are still closely monitoring the developments for possible action.
Different origins
Phivolcs Director Renato Solidum Jr. told the media that the USGS report is not entirely accurate.
"Let me correct the estimation, because the USGS, there is a discrepancy on what they will get because they don't have many stations in the Philippines," Solidum said.
He added the origin of the first quake is the local Batangas fault near the Mabini and Tingloy areas.
Solidum clarified that the two consequent tremors originated at the Manila Trench, meaning they are not related to the first one.
The Phivolcs director explained while the second earthquake has a higher magnitude, it is located in a deeper location along with the third one.
He added the first tremor that occurred in Mabini is now part of a series of earthquakes happening in the Mabini-Tingloy area, which includes the magnitude-5.5 tremor that jolted the province on Tuesday night.
Solidum warned of possible aftershocks and smaller quakes, but said a tsunami is unlikely.
He further explained that the recent Batangas earthquakes will not trigger the so-called "Big One," as it lies in the West Valley Fault.
