Researchers at Washington University in St. Louis have developed new theoretical calculations on how life might have arisen from volcanic gases on Earth and other celestial bodies. The calculations suggest that environmental and chemical conditions are ripe for basic hydrocarbons to form, potentially leading to the emergence of life.
Researchers monitored the Soufriere Hills Volcano's cyclic eruptions to understand mechanisms behind them. They identified cyclical events nearly so well as no one before and made predictions on eruption timing and areas affected, saving lives through evacuation efforts.
Researchers Norman H. Sleep and Cindy J. Ebinger find that a single giant plume of magma rose from Earth's mantle 45 million years ago, shaping Africa's striking geological features such as Mount Kilimanjaro and the Ethiopian plateau.
Geologist Attila Kilinc proposes a new model to explain the forces behind explosive eruptions on Montserrat, citing the oxidation state of magma. The model suggests that mixing hotter and cooler magma leads to water formation, triggering an eruption. Further development of a detection system is needed to accurately predict eruptions.
A new model of Venus suggests that crustal plateaus and volcanic rises were formed by a mechanism similar to hot spot plumes, a process still active on Earth. The thickening of the Venusian lithosphere approximately one billion years ago largely shut down the creation of crustal plateaus.
The $10.3 million, six-year Hawaii Scientific Drilling Program aims to study the formation of volcanoes and the mechanisms within Earth's mantle. Researchers will analyze samples from a 14,500-foot bore hole in Mauna Kea to understand volcanic activity, groundwater movement, and earthquake cycles.
