2010 Solomon Islands Earthquake
Earthquake
The shock was located 105 km (65 mi) southeast of Gizo, 210 km (130 mi) south west of Dadali, Santa Isabel and 295 km (183 mi) north west of Honiara, Guadalcanal. The earthquake was centered under the sea floor near the town of Gizo, which was heavily damaged in the 2007 Solomon Islands earthquake.
Characteristic
Analysis of trench deformation, tsunami run-up heights and wave height data from the ocean revealed that the earthquake was a slow-rupturing "tsunami earthquake". Such earthquakes rupture the upper 20 km portion of a subduction zone, while releasing less energy compared to an ordinary subduction zone earthquake.

Landslides and tsunamis on the islands of Rendova and Tetepare. A tsunami measuring up to 10 feet (3.0 meters) struck Rendova, destroying as many as 200 homes and leaving one-third of Rendova's population homeless. A maximum runup of 7 m (23 ft) was recorded at Rendova Island.
Approximately 1,000 residents have lost their residences, out of the total Rendovan population of just 3,600 people. The village of Retavo, which has a population of approximately 20 people, was hit by a 10-foot tsunami wave. Another village, Baniata, reported that sixteen homes were destroyed and thirty-two were damaged by the earthquake and tsunami. Due to early evacuations, there were no fatalities, but two people sustained minor injuries.
