Volcanic eruption predictions still lack precision

Despite significant progress in monitoring volcanic activity over recent decades, scientists remain far from accurately predicting when an eruption will begin, its potential size, or how long it might last. This is according to a new article published in the prestigious scientific journal Science. Magnús Tumi Guðmundsson, a professor of geophysics at the University of Iceland's Institute of Earth Sciences, led the research, co-authoring the paper with Christopher J. Bean, a doctor of seismology at the Dublin Institute for Advanced Studies. Guðmundsson noted that while monitoring has vastly improved, especially in Iceland where most eruptions 50 years ago were unexpected, precursors are now often detected. However, the primary method for estimating eruption size relies on the probability of past eruptions in similar volcanoes. The study underscores the persistent uncertainties in forecasting these powerful natural events.
