Petrified forest, scientific measurements 2

BEING TIME: Sensors collect data from a 12 million years old tree in the petrified forest of Turkana, Rift Valley, Kenya.

Natural conditions of Turkana allow for the preservation of past forests. Branches, leaves, other remnants of a variety of trees can be found in this natural herbarium. Measurements of the possible signal to be emitted by the 12-million-year-old petrified stump was attempted by "The Listening to the Rift Valley" project.

Electrical resistivity tomography gives information on the tree interior and its integrity. Despite the age of the tree scientists detected changes in membrane polarization in the cells of the transitional zone, and in other tissues.

This signal coming through the ages inspired performances RE-LIVE and BEING TIME of the "Listening to the Rift Valley" project enacted by James Mweu and Olga Kisseleva.
