Tephra transport models try to predict atmospheric dispersion and sedimentation of tephra
depending on meteorology, particle properties, and eruption characteristics, defined by …

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 …

Explosive volcanic eruptions inject hot mixtures of solid particles (tephra) and gasses into
the atmosphere. Entraining ambient air, these mixtures can form plumes rising tens of …

Alaska hosts within its borders over 80 major volcanic centers that have erupted during
Holocene time (< 10,000 years). At least 29 of these volcanic centers (table 1) had historical …

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 …

Large‐scale volcanic eruptions produce fine ash (< 200 μm) which has a long atmospheric
residence time (1 hour or more) and can be transported great distances from the volcanic …

Lightning and electrification at volcanoes are important because they represent a hazard in
their own right, they are a component of the global electrical circuit, and because they …

Volcanic activity has caused significant hazards to numerous airports worldwide, with local
to far-ranging effects on travelers and commerce. Analysis of a new compilation of incidents …

Water is the dominant component of volcanic gas emissions, and water phase
transformations, including the formation of ice, can be significant in the dynamics of volcanic …

In this paper we describe the results of a project ongoing at the Istituto Nazionale di
Geofisica e Vulcanologia (INGV). The objective is to develop and implement a system for …
