  • Research field

    • Topics : Dynamics of explosive eruptions, ash plumes and jets, field volcanology, geophysics.
    • Target volcanoes : Etna, Tajogaite (Cumbre Vieja, La Palma), Soufrière de Guadeloupe, Sabancaya, Stromboli, Popocatépetl, Yasur, Arenal, Auvergne, Soufrière Hills Montserrat, Mont St. Helens.
    • Tools : Remote sensing (Doppler radar, infrared radiometry, disdrometer), numerical models (electromagnetic scattering, ballistics, plume column), sub-surface geophysical methods

    1. Eruption Source Parameters of volcanic jets and ash plumes: radar and disdrometer measurements

    Eruption Source Parameters controlling the plume dynamics as well as ash dispersal and fallout are crucial to initialize ash dispersal models and forecast the impact of ash on air trafic, populations and infrastructures. They can be retrieved from measurements of ground-based radars and disdrometers deployed near the volcano, a field of expertise of OPGC-LMV through its unique platform of ground-based transportable instruments: VOLDORAD.

    The source term of ash plumes retrieved from high-resolution radar scans

     These reflectivity scans were measured inside the eruptive column of an ash plume of Sabancaya volcano (Peru) using our new mm-wave radar VOLDORAD-3. In addition to providing plume height and width, radar reflectivities show the particle mass internal distribution and can be converted to ash concentrations (e.g. up to 1 g/m3 for weak plumes at Stromboli) using proximal records of ash fallout from disdrometers (Freret-Lorgeril et al., 2019 ) or by electromagnetic backscattering modelling if particle size distribution can be constrained (Gouhier & Donnadieu, 2008 ). Doppler velocities are also measured, providing internal particle velocities and exit velocities.

    Methodological development : Mass Eruption Rate

    Our monitoring radar on Etna (VOLDORAD-2B) provides the echo power and Doppler velocities of lava fountain-fed tephra plumes. From these combined parameters  calibrated from the VOLDORAD database of 47 paroxysms and a plume model, tephra Mass Eruption Rates at Etna can now be retrieved  directly from radar measurements in real-time , a major achievement of the EUROVOLC project (collab. INGV-OE). Total erupted mass are found to commonly reach 108-109 kg, 75% being released during the climax (15-20 min) with MER reaching 105-106 kg/s (Freret-Lorgeril et al., 2018).

    Lava jets: at-vent velocities, gas fluxes, tephra mass

    Transportable UHF Doppler radar (VOLDORAD-2) aiming at the vent of Yasur volcano (Vanuatu). High rate measurements reveal pyroclast exit velocities in the range 50 et 320 m/s, slightly higher than Stromboli (Chevalier et Donnadieu, 2015 ). From measured maximum velocities (red curve) and vent diameter, explosive degassing fluxes can be estimated (4*105 m3/h). Mie diffusion modelling of the radar backscattered power (blue curve) provides masses of ejecta ranging from many hundreds of kg to several tens of tons per explosion.

    Ash dispersal forecast using radar retrievals

    Transport modelling (WRF-Chem) of volcanic emissions (ash, SO2) using the radar-derived near-vent tephra Mass Eruption Rate in input leads to improved dispersal forecast, particularly for short-lived eruptions with large source rate fluctuations such Etna paroxysms, as verified from satellite MSG SEVIRI images for the 23 November 2013 eruption (Donnadieu et al., 2021 ). Echo power (lower curves) and Doppler velocities (upper left curves) of lava fountain-fed tephra plumes are measured above the eruptive craters by our L-band monitoring radar at Etna (VOLDORAD-2B). Near-vent vertical ejection velocities of lava fountains, for instance, can exceed 300 m/s (Donnadieu et al., 2016, 2005). See below the numerical simulation of ash dispersal over Mediterraean area over days following such an eruption (© Umberto Rizza, ISAC-CNR); these results improve our knowledge of environmental impacts from volcanic pollutants released in the atmosphere and help assess hazards from short-lived explosive eruptions (air trafic, environment, health etc).

    Other animated gif movies from sequences of paroxysms at Etna here (from Rizza, Donnadieu et al., 2023).

    PM10 ash dispersal simulation maps show that the very fine ash (<10 microns) from Etna eruption sequences easily contaminate the airspace around the volcano within a radius of about 1000 km in a matter of a few days. Synoptic patterns with relatively weak tropospheric currents lead to the accumulation of PM10 ash at a regional scale all around Etna.

    2. Processes controlling the dynamics of ash plumes and fallout

    Collective sedimentation from wind-affected ash plumes

    Disdrometer data highlighted pulsatory phases of increased proximal sedimentation rate from transient weak dilute plumes (A), consistent with reflectivity variations inside ash plumes measured by mm-wave radar (B). From time series of both instruments and simple analog experiments, we developed a conceptual model for intermittent collective sedimentation from wind-affected ash plumes (C; Freret-Lorgeril et al., 2020 ) whereby the dynamics of wind-driven rolls in ash clouds can govern the production of gravitational instabilities and the occurrence and timing of ash fingers that form descending sediment thermals in turn. This study suggests that ambient wind should affect the maximum size and minimum concentration of ash particles needed to form fingers but also control where and when fingers form at the base of wind-drifted ash plumes. These novel predictions should contribute to better assess hazards related to fine ash dispersal from the most frequent style of eruptions.

    3. Geophysics in support of studies in volcanology, geology, archeology, hydrogeology

    Aside from my main research on tephra plumes, I contribute to geophysical surveys either in the frame of large projects involving heavy field deployments or of local studies in archeogeophysics, volcanology, geology and hydrogeology.

    • Electrical Resistivity Tomography  survey of Puy de Dôme, in the frame of A. Portal’s PhD work (Portal et al., 2013)

  • As a CNAP researcher in an Observatory (OPGC), a third of my time is statutorily devoted to collective tasks serving the scientific community : in my case, the management of the VOLDORAD service in the frame of the french National Service of Observations in Volcanology (SNOV). This platform comprises instrumental development of radars and disdrometers for operational field deployment and measurement campaigns, and elaboration of open-access data bases from collected observations; sensors and data bases are made available to the scientific community and mainly used in the volcanology and atmospheric fields. See some illustrations of results in my Research page. This activity receives strong support from OPGC engineers and transverse services.

    As a volcanologist I also contribute to the volcano monitoring of Soufrière de Guadeloupe and formerly Etna, and punctually to back up monitoring duties of the french volcano Observatories of Piton de la Fournaise and Mayotte (OVPF).

    This sample is a large scoriaceous lapilli (3 cm long) from the Tajogaite (Cumbre Vieja) 2021 Strombolian eruption  (F. Donnadieu, J. de Paoli) in La Palma (Canaria islands). Cristals having a different atomic density from glass and gas bubbles/air, they show up with a different opacity to the X-rays and are displayed by thresholding the images, then assembled to form a 3D volume.

    The Chambois quarry in lava flow from Puy de Côme

    Beautiful fluidality textures at the margin of the Puy de Côme lava flow, as seen from the quarry, showing alternation of lava layers, some of which are rich in elongated gas bubbles. Lava is cut into blocks to shape decorative lava stones. Highly esthetical texture effects are created at the surface of the blocks by melting lava rock powder in a furnace.

    Neolitic tools carved in volcanic stone

    Arrowheads and biface carved in volcanic rocks from the Zemmour noir region in Mauritania by neolithic populations, several thousand years ago.
