The 1994 Mindoro earthquake occurred at near Mindoro, Philippines. It had a moment magnitude of 7.1 and a maximum Rossi–Forel of VII (Very strong tremor). It is associated with a ground rupture, called the Aglubang River fault.Rimando, R.E., Punongbayan, R.S., Geronimo-Catane, S.G., Mirabueno, H.S., Rasdas, A.S., 1995. Ground rupture of the November 15, 1994, Oriental Mindoro (Philippines) earthquake. XXI General Assembly of IUGG, Abstracts, p. A422. Seventy eight people were reported dead, and 7,566 houses were damaged. The earthquake generated a tsunami and landslides on the Verde Island.
Earthquake The epicenter of this earthquake was located in the Verde Island Passage, a strait separating Luzon and Mindoro. The focal mechanism showed predominantly right-lateral strike-slip faulting. The released seismic moment was about 5.12×1019 Nm.
Surface faulting
The Aglubang River fault, which shows a right-lateral strike-slip sense of movement, extends from Malaylay Island in the north of Oriental Mindoro to Alcate, Victoria in the south. Measurements along the rupture reveal a maximum horizontal displacement of and a maximum vertical displacement of .PHIVOLCS Quick Response Teams, December 1994. PHIVOLCS Special Report No. 2. THE November 15, 1994, Mindoro Earthquake.
Tsunami
The earthquake generated a tsunami, which affected Mindoro, the Verde Island, the Baco Islands, and Luzon. Some concrete structures also suffered moderate damage in the tsunami. In Baco Islands, the vertical run-up reached . The tsunami was also recorded in Lobo. The tsunami was larger than expected considering the strike-slip movement of the earthquake.
