Geological Summary

The elongated island of Pinta is the northernmost of the active Galápagos volcanoes. Pinta is a shield volcano with numerous young cones and lava flows originating from NNW-trending fissures. A steep sea cliff truncates the western side of the volcano, which lacks the prominent summit caldera of Fernandina and Isabela Island volcanoes. The fresh, unvegetated lava flows that cover the SE and northern flanks appear to have been erupted during the past few thousand or few hundred years (McBirney and Williams 1969). An eruption of uncertain nature was reported in 1928 (Catalog of Active Volcanoes of the World).

The elongated island of Pinta is the northernmost of the active Galápagos volcanoes. This view from the summit of Pinta looks down on pyroclastic cones and lava flows on the southern flank of the shield volcano. Numerous young cones and lava flows originated from NNW-trending fissures cutting the island. The fresh, unvegetated lava flows that cover the SE and northern flanks appear to have been erupted during the past few thousand or few hundred years. The island in the distance is Marchena volcano.

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.
