The Solomon Islands tsunami was generated by a Mw 7.1 earthquake (8.800°S, 157.370°E ), at 22:36:28 UTC, 105 km (65 miles) SSE of Gizo, New Georgia Islands, Solomon Isl. (according to the USGS). In approximately an hour 15 min, and an hour 30 min, respectively, the tsunami was recorded at DART® buoys 55023 and 55012. Forecast results shown below were created with the NOAA forecast method using MOST model with the tsunami source inferred from DART® data.
The graphics to the left display forecast results, showing qualitative and quantitative information about the tsunami, including tsunami wave interaction with ocean floor bathymetric features, and neighboring coastlines. Tsunami model amplitude information is shown color-coded on top of blue-shaded sea floor bathymetry.
The tsunami waves first arrived at Honiara, Solomon Islands, (approximately 300 km southeast from earthquake epicenter) earlier than other tide gages, at 23:29 UTC, about 53 minutes after the earthquake.
