Lusi mud eruption a natural disaster
A new study released on July 21st by leading European scientists from Bonn University and ETH-Zurich concludes that the Lusi mud eruption is a natural disaster and a geological rarity of a newborn, tectonic-scale hydrothermal system triggered by the Yogyakarta earthquake. This extensive, peer reviewed study has been published in the one of the world's most preeminent scientific journals - Nature Geoscience.
With their publication, scientists from Bonn and Zürich point out, that earthquakes can trigger processes over long distances, and this focusing effect may apply to other hydrothermal and volcanic systems.
Many researchers believed that the earthquake epicenter was too far from Lusi to have activated the mud volcano“, says Prof. Dr. Stephen A. Miller from the department of Geodynamics at the University of Bonn. However, using their computer simulations that include the geological features of the Lusi subsurface, the team of Prof. Dr. Miller concluded that the earthquake was the trigger, despite the long distance.
"Being a geological rarity, the mud volcano may contribute to a better understanding of triggering processes and relationships between seismic and volcanic activity", says Prof. Dr. Miller, "Maybe this work will once and for all settle the long-standing controversy and focus instead on helping those affected".
