Geological Summary

The densely forested Tepi basaltic shield volcano is at the northern end of the Turkana rift, ~300 km W of the center of the main Ethiopian rift, and was constructed along a zone of ENE-trending faults that extend in line with the Gulf of Aden. It is capped by prominent cinder cones and small craters, and there are associated hot springs. Three satellitic centers are located along an E-W line north of the main shield. Lava flows have traveled down pre-existing valleys. Davidson (1983) considered it to be of probable Holocene age, but no eruption dates are known.

Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Tepi. If this volcano has had large eruptions (VEI >= 4) prior to 12,000 years ago, information might be found on the Tepi page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

Deformation History

There is no Deformation History data available for Tepi.

Emission History

There is no Emissions History data available for Tepi.

Photo Gallery

The densely forested Tepi basaltic shield volcano lies about 300 km west of the Ethiopian Rift in southern Ethiopia. A small crater near the center of this NASA Landsat image (with north to the top) is one of many features on this broad volcano. Lava flows have traveled down pre-existing valleys, and there are active hot springs. The smoke plume at the right is from a vegetation fire.

The vegetated Tepi volcanic field contains lava flows, scoria cones, and craters, located in Ethiopia, W of the Eastern Rift Valley volcanoes. Bishan Waka or Lake Kabo has filled the crater near the center of this 3 March 2019 Sentinel-2 satellite image (N is at the top; this image is approximately 16 km across).

The Copernicus Browser replaced the Sentinel Hub Playground browser in 2023, to provide access to Earth observation archives from the Copernicus Data Space Ecosystem, the main distribution platform for data from the EU Copernicus missions.

WOVOdat
   Single Volcano View
   Temporal Evolution of Unrest
   Side by Side Volcanoes

WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.

GVMID Data on Volcano Monitoring Infrastructure The Global Volcano Monitoring Infrastructure Database GVMID, is aimed at documenting and improving capabilities of volcano monitoring from the ground and space. GVMID should provide a snapshot and baseline view of the techniques and instrumentation that are in place at various volcanoes, which can be use by volcano observatories as reference to setup new monitoring system or improving networks at a specific volcano. These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments.

IRIS seismic stations/networks

Incorporated Research Institutions for Seismology (IRIS) Data Services map showing the location of seismic stations from all available networks (permanent or temporary) within a radius of 0.18° (about 20 km at mid-latitudes) from the given location of Tepi. Users can customize a variety of filters and options in the left panel. Note that if there are no stations are known the map will default to show the entire world with a "No data matched request" error notice.

Users can customize the data search based on station or network names, location, and time window. Requires Adobe Flash Player.

Large Eruptions of Tepi

Information about large Quaternary eruptions (VEI >= 4) is cataloged in the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
