1994 Mindoro earthquake

The 1994 Mindoro earthquake occurred at 03:15:30 PST on November 15 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 35 km ground rupture, called the Aglubang River fault. 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 4 m and a maximum vertical displacement of 1.9 m.

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 8.5 m. The tsunami was also recorded in Lobo. The tsunami was larger than expected considering the strike-slip movement of the earthquake.
