Geological Summary

The Krísuvík volcanic system (also spelled Krysuvik) consists of a group of NE-SW-trending basaltic crater rows and small shield volcanoes cutting the central Reykjanes Peninsula west of Kleifarvatn lake. Several eruptions have taken place since the settlement of Iceland, including the eruption of a large lava flow from the Ogmundargigar crater row around the 12th century. The latest eruption at Krísuvík took place during the 14th century.

The two westernmost of five NE-SW-trending volcanic systems on the Reykjanes Peninsula cut diagonally across this aerial photo. The Reykjanes volcanic system, which lies near the SW tip of the peninsula, where the Mid Atlantic Ridge rises above sea level, has produced Holocene lava fields that extend to the western and southern coasts. The Krísuvík volcanic system, on the right side of the photo, has produced several eruptions since the settlement of Iceland. The latest of these took place during the 14th century.

Several eruptions have taken place since the settlement of Iceland, including the emplacement of a large lava flow from the Ogmundargigar crater row around the 12th century that reached the southern coast of the Reykjanes Peninsula (lower right) along a broad front.

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.
