What is happening at Negros Oriental, Cebu and nearby islands?
At 11:49 AM on 6 February 2012, a moderate size earthquake of magnitude 6.9 shook Negros, Cebu and nearby islands.  Aftershocks of lesser magnitude followed a few minutes after the main shock. 23 hours later, 896 aftershocks have been recorded by the PHIVOLCS seismic monitoring network.
The main shock and ensuing aftershocks have epicenters on the eastern coast of Negros Oriental, near the municipality of Tayasan.  It is a shallow earthquake, with focal depth of 10 kilometers. Although there are identified active faults in the island, such as the Central Negros Fault, further investigation needs to be done to determine the fault responsible for this earthquake.
Intensity reports showed that municipalities of Tayasan, Vallehermoso, Guihulngan and Dumaguete City (Negros Oriental) felt the strongest ground shaking at PEIS  VII (destructive ground shaking). Furthermore, the surrounding areas of La Carlota City and La Castellana (Negros Occidental), Tanjay and Manjud (Negros Oriental), Argao, Dalaguete, Barili, Cebu City (Cebu) and Clarin (Bohol) felt the ground shaking at PEIS VI (very strong ground shaking).  There were reports of felt intensities as far as 200 kilometers away from the epicentral area.  The strong ground shaking, especially in the epicentral area, caused damage to or collapse of weak structures, liquefaction in low-lying soft grounds, and landslide in steep slopes.  There were also reported sea disturbance in some coastal areas.
Moderate-magnitude  earthquakes have also affected Negros Island in the past!
On 5 May 1925, a magnitude 6.8 earthquake occurred at Southern Negros.  The towns of Bais, Tanjay, Tolong and Siaton felt the strongest intensity of ground shaking at PEIS VI to VII.  There were report of damaged buildings in Bais and Siaton, while in Dumaguete, landslides along ridges and fissures along rivers and mangrove areas.
