Mindoro is located at the southern end of the Manila Trench, which is collision of south-moving Philippine mobile belt (PCB) and NW-moving Palawan continental block (PMB).To tackle the issue of 2017 Batangas earthquake sequence, we deployed a broadband seismic array of four stations since 2013. To increase station coverage, we recorded by the array provides an opportunity to better understand the tectonics by analyzing its distribution and stress state. We use the monitoring network to record the P-wave and S-wave travel time data of this earthquake sequence. The artificially adjusted seismic wave is used to invert the source parameters and relocation using HypoDD to eliminate the influence of the velocity structure on the positioning results. The results of the positioning show that the Batangas earthquake sequence can be divided into 4/4 12:58 event-based foreshock sequence and double main shock sequence headed by 4/8 07:07 and 07:09 events. In the spatial distribution, the range of motion of the foreshock sequence is narrow, trend to the north-south trend. The main shock sequence is widely distributed, showing a northwest-southeast distribution. The search for the trending slip earthquake in the GCMT catalogue is mostly the left shift rupture on the Sibuyan Verde Passage Fault (SVPF), and the right shift rupture only the 1994 Mindoro earthquake and this earthquake sequence. We speculate that SVPF enters the northern part of Mindoro as a stress-converting region. Keywords: Mindoro、Batangas、Earthquake sequence
