}}The 1994 Mindoro earthquake occurred at {{tooltip|03:15:30 PST on November 15|19:15:30 UTC on November 14}} near Mindoro, the Philippines. It had a moment magnitude of 7.1 and a maximum Mercalli intensity of VII (Very strong). It is associated with a 35 kilometer-long ground rupture, called the Aglubang River fault.[1] Seventy eight people were reported dead,[2] 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.[3] The released seismic moment was about 5.12×1019 Nm.[4]
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 meters and a maximum vertical displacement of 1.9 meters.[1][5]
Tsunami
The earthquake generated a tsunami, which affected Mindoro, the Verde Island, the Baco Islands,[6] and Luzon. Some concrete structures also suffered moderate damage in the tsunami. In Baco Islands, the vertical run-up reached {{convert|8.5|m|sp=us}}. The tsunami was also recorded in Lobo.[7] The tsunami was larger than expected considering the strike-slip movement of the earthquake.[8]
