Geological Summary

Methana volcano consists of a basaltic-andesite to rhyodacitic lava dome complex forming the Methana Peninsula in the Sarronian Gulf on the NE side of Peloponnesus. Potassium-Argon ages for the older part of the complex range from 900,000 to 550,000 years, although activity may have begun during the late Pliocene. A younger phase of activity took place from about 380,000-290,000 years ago, forming a series of lava domes and flows. The youngest dome, Kameno Vouno, on the NW side of the peninsula, was formed in the 3rd century BCE and produced a lava flow that traveled 500 m beyond the coastline. Hot springs are found at several locations along the coast of the peninsula.

Malja Khoriou lava dome, seen here from the SE, lies on the eastern side of the Methana Peninsula and is one of several basaltic-andesite to rhyodacitic lava domes forming the Methana volcanic complex. The peninsula extends into the Sarronian Gulf on the NE side of the Peloponnesus Peninsula. The youngest dome, Kameno Vouno, on the NW side of Methana Peninsula, was formed in the 3rd century BC and produced a lava flow that traveled 500 m beyond the coastline.

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.
