A team led by LMU volcanologist Dr. Janine Birnbaum has successfully reconstructed the conditions within a magma chamber by analyzing magma chips obtained from drilling operations at the Krafla volcanic field in Iceland. In 2009, the Iceland Deep Drilling Project 1 (IDDP-1) well unexpectedly encountered magma at a depth of just over 2 km. The rapid cooling of this magma by drilling fluids resulted in glass chips containing fewer dissolved gases than expected. Using a new numerical model, researchers determined that the magma lost gas within five minutes during the drilling process, before solidifying into glass. This groundbreaking research, published in _Nature_, offers crucial insights into magma behavior and could enhance volcanic monitoring and geothermal energy extraction.
