As our ability to detect volcanic unrest improves, we are increasingly confronted with the
question of whether the unrest has a magmatic origin (magma on the move) or a non …

Using multiple lines of evidence, we demonstrate that volcanic ash deposition in August
2008 initiated one of the largest phytoplankton blooms observed in the subarctic North …

In this chapter we discuss our InSAR observations of Aleutian volcanoes that have been
active during historical time, starting with Kiska Volcano in the west and ending with Mount …

Iron is a key limiting micro-nutrient for marine primary productivity. It can be supplied to the
ocean by atmospheric dust deposition. Volcanic ash deposition into the ocean represents …

Eruptive column models are powerful tools for investigating the transport of volcanic gas and
ash, reconstructing past explosive eruptions, and simulating future hazards. However, the …

We combine new observations of volcano deformation in Latin America with more than 100
previous deformation studies in other areas of the world to constrain the frequency …

Starting soon after the 1997 eruption at Okmok volcano and continuing until the start of the
2008 eruption, magma accumulated in a storage zone centered∼ 3.5 km beneath the …

Interferometric synthetic aperture radar (InSAR) data indicate that the caldera of Okmok
volcano, Alaska, subsided more than a meter during its eruption in 1997. The large …

Analyzing seismic data in a timely manner is essential for potential eruption forecasting and
early warning in volcanology. Here, we demonstrate that unsupervised machine learning …

Volcano crater lakes, while picturesque, can sometimes mask the occurrence of small
eruptions or hydrothermal fluid release events. However, these seemingly hidden events …
