Geological Summary

The andesitic-to-dacitic Nabukelevu lava-dome complex occupies the SW end of Kadavu Island at the southern end of the Fiji archipelago. The high point of the Nabukelevu complex is 805 m Mt. Washington, an andesitic lava dome. Flat-lying dacitic lava flows are found at Cape Washington along the west coast and at Talaulia Bay on the NE coast. NNE-trending faults cut the complex in several locations and define its eastern boundary. The dome complex is cut by several collapse scarps that were the source of debris avalanches that have incorporated human artifacts and remains. Debris avalanches have entered the sea on the both the northern and southern sides of the volcano. Onshore and offshore deposits as well as native legends indicate that several eruptions have occurred at Nabukelevu during the Holocene. Block-and-ash flows related to dome growth have occurred within the past few hundred years.

Nabukelevu volcano, whose summit lies between the two clouds near the center of this NASA Space Shuttle image, occupies the SW end of Kadavu Island at the southern end of the Fiji archipelago. Debris avalanches from collapse of the Mt. Washington lava-dome complex reached both the northern coast to the right of Cape Washington (the small peninsula at the upper left) and horseshoe-shaped Daviqele Bay (bottom center) and the south. Block-and-ash flows related to dome growth have occurred within the past few hundred years.

MODVOLC - HIGP MODIS Thermal Alert System Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
MIROVA Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.
