More than 800 million people live in proximity to active volcanoes and could be directly
impacted by potential eruptions. Mitigation of future volcanic hazards requires adequate …

Abstract The Andean Southern Volcanic Zone (SVZ) concentrates many of the most active
volcanoes of the Andean continental arc, as well as the region's most recent and impactful …

Satellite monitoring of volcanic activity typically includes four primary observations:(1)
deformation and surface change,(2) gas emissions,(3) thermal anomalies, and (4) ash …

Abstract The Masaya Triple Layer tephra was deposited~ 2100 years ago during a basaltic
Plinian eruption of Masaya caldera, Nicaragua, and is one of few known examples of this …

The origin of gaps or zoning in the composition of erupted products is critical to
understanding how sub-volcanic reservoirs operate. We characterize the compositionally …

Although rare, basaltic Plinian eruptions represent a considerable volcanic hazard. The low
viscosity of crystal-poor basaltic magma inhibits magma fragmentation; however, Las Sierras …

The liquid viscosity of multiphase systems is usually retrieved by the use of combined
chemical analysis and empirical chemistry-based models. Here we present an alternative …

Some volcanoes are known for repeatedly producing explosive but short-lived eruptions (<
half a day) every decade or so. These eruptions are often preceded by limited unrest signals …

Volatile exsolution is widely considered to be capable of generating magmatic overpressure
and triggering volcanic eruptions. Despite its role as an eruption trigger, exsolution-driven …

Beyond the catastrophic environmental effects of large (> 1 km3) volcanic landslides, their
impact on underlying magmatic systems remains unclear. Chemical variations in post …
