Here is what the page “Kīlauea Volcano’s Swelling Summit Helps Scientists Forecast Lava Fountain Eruptions” contains. Scientists studying Kīlauea in Hawaii have gained new insight into episodic lava fountaining, a rare volcanic behavior where hours-long bursts of molten lava and gas alternate with quiet pauses lasting days to weeks. Using ground deformation data, researchers found that the volcano’s summit swells and subsides in a repeating pattern that correlates with the start and stop of lava fountains. This swelling, caused by accumulating magma and gas pressure, provides a measurable precursor that could improve forecasting of these dramatic events.
The findings are significant for communities near active volcanoes in Hawaii, Iceland, and Italy, where similar fountaining has occurred. Better prediction could enhance hazard warnings and reduce risks to people and infrastructure. The study, published in a leading geoscience journal, analyzed multiple fountaining episodes at Kīlauea’s summit crater and nearby rift zones.
