Maurizio Battaglia
I am the deformation specialist for the Volcano Disaster Assistance Program (VDAP). I write scientific software, train staff at volcano observatories, mentor young (and young at heart) scientists, model deformation and gravity data, and support volcano observatories during volcanic unrest.

Twenty years (1990–2010) of geodetic monitoring of Galeras volcano (Colombia) from continuous tilt measurements. Twenty years (1990–2010) of geodetic monitoring of Galeras volcano (Colombia) from continuous tilt measurements.
Galeras - an andesitic stratovolcano part of the Galeras Volcanic Complex - is one of the most active volcanoes in Colombia. Historic activity is centered on a small-volume cone inside the youngest amphitheater, which breaches the west flank of the volcano. At least 30 confirmed eruption periods have been recorded in the past 480 years, with episodes of unrest ranging from weak fumarolic...

Construction of probabilistic event trees for eruption forecasting at Sinabung volcano, Indonesia 2013–14 Construction of probabilistic event trees for eruption forecasting at Sinabung volcano, Indonesia 2013–14
Eruptions of Sinabung volcano, Indonesia have been ongoing since 2013. Since that time, the character of eruptions has changed, from phreatic to phreatomagmatic to magmatic explosive eruptions, and from production of a lava dome that collapsed to a subsequent thick lava flow that slowly ceased to be active, and later, to a new lava dome. As the eruption progressed, event trees were...

Mass addition at Mount St. Helens, Washington, inferred from repeated gravity surveys Mass addition at Mount St. Helens, Washington, inferred from repeated gravity surveys
Measurements of subtle changes in the Earth’s gravityfield can provideinformation on the addition/loss of mass (e.g., magma or aqueousfluids) beneath a volcano. In this study, wemeasured gravity at Mount St. Helens from 2010 to 2016 to investigate possible mass changes followingthe 2004–2008 dome-forming eruption. The raw gravity measurements were corrected for changes in themass and...

Magma transfer at Campi Flegrei caldera (Italy) before the 1538 AD eruption Magma transfer at Campi Flegrei caldera (Italy) before the 1538 AD eruption
Calderas are collapse structures related to the emptying of magmatic reservoirs, often associated with large eruptions from long-lived magmatic systems. Understanding how magma is transferred from a magma reservoir to the surface before eruptions is a major challenge. Here we exploit the historical, archaeological and geological record of Campi Flegrei caldera to estimate the surface...

A thermodynamical model for the surface tension of silicate melts in contact with H2O gas A thermodynamical model for the surface tension of silicate melts in contact with H2O gas
Surface tension plays an important role in the nucleation of H2O gas bubbles in magmatic melts and in the time-dependent rheology of bubble-bearing magmas. Despite several experimental studies, a physics based model of the surface tension of magmatic melts in contact with H2O is lacking. This paper employs gradient theory to develop a thermodynamical model of equilibrium surface tension...

Shifts in the eruptive styles at Stromboli in 2010–2014 revealed by ground-based InSAR data Shifts in the eruptive styles at Stromboli in 2010–2014 revealed by ground-based InSAR data
Ground-Based Interferometric Synthetic Aperture Radar (GBInSAR) is an efficient technique for capturing short, subtle episodes of conduit pressurization in open vent volcanoes like Stromboli (Italy), because it can detect very shallow magma storage, which is difficult to identify using other methods. This technique allows the user to choose the optimal radar location for measuring the...

Keeping watch over Colombia’s slumbering volcanoes Keeping watch over Colombia’s slumbering volcanoes
Located in the Central Cordillera (Colombian Andes), Nevado del Ruiz is a volcanic complex, topped by glaciers, rising 5,321 m above sea level. A relatively small explosive eruption from Ruiz's summit crater on November 13, 1985, generated an eruption column and sent a series of pyroclastic flows and surges across the volcano's ice-covered summit. Pumice and meltwater produced by the hot

Gravity changes and deformation at Kīlauea Volcano, Hawaii, associated with summit eruptive activity, 2009-2012 Gravity changes and deformation at Kīlauea Volcano, Hawaii, associated with summit eruptive activity, 2009-2012
Analysis of microgravity and surface displacement data collected at the summit of Kīlauea Volcano, Hawaii (USA), between December 2009 and November 2012 suggests a net mass accumulation at ~1.5 km depth beneath the northeast margin of Halema‘uma‘u Crater, within Kīlauea Caldera. Although residual gravity increases and decreases are accompanied by periods of uplift and subsidence of the...

This manual provides the physical and mathematical concepts for selected models used to interpret deformation measurements near active faults and volcanic centers. The emphasis is on analytical models of deformation that can be compared with data from the Global Positioning System (GPS) receivers, Interferometric synthetic aperture radar (InSAR), leveling surveys, tiltmeters and...

Shallow magma accumulation at Kīlauea Volcano, Hawai‘i, revealed by microgravity surveys Shallow magma accumulation at Kīlauea Volcano, Hawai‘i, revealed by microgravity surveys
Using microgravity data collected at Kīlauea Volcano, Hawai‘i (United States), between November 1975 and January 2008, we document significant mass increase beneath the east margin of Halema‘uma‘u Crater, within Kīlauea's summit caldera. Surprisingly, there was no sustained uplift accompanying the mass accumulation. We propose that the positive gravity residual in the absence of...

Analytical modeling of gravity changes and crustal deformation at volcanoes: The Long Valley caldera, California, case study Analytical modeling of gravity changes and crustal deformation at volcanoes: The Long Valley caldera, California, case study
Joint measurements of ground deformation and micro-gravity changes are an indispensable component for any volcano monitoring strategy. A number of analytical mathematical models are available in the literature that can be used to fit geodetic data and infer source location, depth and density. Bootstrap statistical methods allow estimations of the range of the inferred parameters...

Uplift and magma intrusion at Long Valley caldera from InSAR and gravity measurements Uplift and magma intrusion at Long Valley caldera from InSAR and gravity measurements
The Long Valley caldera (California) formed ~760,000 yr ago following the massive eruption of the Bishop Tuff. Postcaldera volcanism in the Long Valley volcanic field includes lava domes as young as 650 yr. The recent geological unrest is characterized by uplift of the resurgent dome in the central section of the caldera (75 cm in the past 33 yr) and earthquake activity followed by...
