Geological Summary

Marsabit is a massive, 6300 sq km basaltic shield volcano located 170 km east of the center of the East African Rift. Its slopes are dotted with 22 maars and 180 cinder cones, most of which are concentrated along NW- and NE-trending belts that cut across the thickly vegetated summit region. The main phase of shield construction occurred during the Pliocene. Quaternary activity shifted to explosive activity that formed maars accompanied by further extensive effusion of lava flows. The youngest dated lava flow at Marsabit has a Potassium-Argon age of 0.68 +/- 0.16 million years ago, but more recent activity has also occurred. The youngest lava flows are unvegetated, and Key (1987) mapped the post-shield cinder cones as Pleistocene to Recent in age.

The Global Volcanism Program is not aware of any Holocene eruptions from Marsabit. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Marsabit page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

A Space Shuttle perspective shows part of Marsabit, a massive, 6300 sq km shield volcano located 170 km east of the center of the East African Rift. Its slopes are dotted with 180 cinder cones and 22 maars, such as the prominent circular one below the thickly vegetated summit of the shield volcano. Most of these vents are concentrated along NW- and NE-trending belts cutting across the summit. The youngest lava flows are unvegetated, and the post-shield cinder cones were mapped as Pleistocene to Holocene in age.

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.
