Triggering the 2022 eruption of Mauna Loa.

Distinguishing periods of intermittent unrest from the run-up to eruption is a major challenge at volcanoes around the globe. Comparing multidisciplinary monitoring data with mineral chemistry that records the physical and spatio-temporal evolution of magmas fundamentally advances our ability to forecast eruptions. The recent eruption of Mauna Loa, Earth's largest active volcano, provides a unique opportunity to differentiate unrest from run-up and improve forecasting of future eruptions.

Drinking motives mediate the associations between urgency and hazardous/harmful alcohol use among moderate-to-heavy drinking men who have sex with men (MSM).

Unlabelled: Urgency, the tendency to act rashly under extreme emotions, has been associated with higher rates of hazardous/harmful drinking. Moreover, previous work suggests that the association between urgency and hazardous/harmful drinking may be mediated by drinking motives. The current study sought to replicate and extend this research to men who have sex with men (MSM), a population that has shown increased alcohol-related health risk behavior.

Magma reservoir failure and the onset of caldera collapse at Kīlauea Volcano in 2018.

Caldera-forming eruptions are among Earth's most hazardous natural phenomena, yet the architecture of subcaldera magma reservoirs and the conditions that trigger collapse are poorly understood. Observations from the formation of a 0.8-cubic kilometer basaltic caldera at Kīlauea Volcano in 2018 included the draining of an active lava lake, which provided a window into pressure decrease in the reservoir.
