The Krafla Magma Testbed Symposium

Museum Mineralogia München,

10 – 12 April, 2024​

Krafla Magma Testbed (KMT) Symposium

Under the theme “Together, toward a greener and safer future”, the KMT Symposium aims to gather the scientific community from the fields of geosciences and deep-drilling engineering to exchange knowledge relevant to the Krafla system.

The Krafla Magma Testbed vision will be introduced and the KMT team will review the current knowledge of the Krafla volcanic and geothermal systems, thus providing an opportunity to get involved with this ground-breaking initiative as it rapidly gains momentum.​
