Project Summary

Ol Doinyo Lengai, a frequently active volcano in northern Tanzania, is instrumented with a real-time GNSS network to understand transient behavior and the relationship between volcanism and rifting. The data are telemetered to UNAVCO and then distributed free with open access through the UNAVCO Data Archive as well as the Tanzania Volcano Observatory CHORDS Portal.

UNAVCO Support

John Galetza of UNAVCO and Mr. Kristof Nkembo of Ardhi University completed repairs, maintenance, and upgrades to the existing GNSS monitoring network around Ol Doinyo Lengai. The work included replacing faulty solar charge controllers and dead batteries; reconstructing all solar panel arrays so as to provide shading to hardware and battery enclosures; vegetation control to prevent damage in the event of wildfire; re-organizing power, telemetry and GNSS systems at the communication hub and reference station near the village of Engaresero; and reinstalling two GNSS stations on the south side of the volcano which were removed under threat of vandalism earlier this year.
