The Geophysics Group at University College Dublin seeks a highly motivated MSc candidate (Early Stage Researcher) to investigate the ability of “state of the art” inversion procedures to successfully capture the nature of shallow volcanic seismic sources (in particular long-period (LP) sources). Since seismic and deformation sources are closely related to the overall dynamics within the volcanic edifice, quantifying our ability to accurately invert for such sources is of great importance for further advances in the field.

This project will include:
(i) using numerical simulations for wave propagation through a complex medium with topography,
(ii) using the source inversion tools available in the UCD Seismology Lab.,
(iii) extensive collaboration with other groups in the NEMOH Consortium, especially in deformation studies.

In particular, we are interested in inverting for seismic sources due to the physical processes which generate both the seismic and deformation signals observed on volcanoes.

The successful candidate will learn how to use software for seismic data handling, and will become familiar with developing and running numerical simulations. They will also study relationships between seismicity and deformation on volcanoes.

Existing basic programming skills in C, FORTRAN or Matlab are desirable. A university level qualification in geophysics, seismology, physics, applied mathematics or similar is required.

Standard Marie Curie conditions for eligibility apply. For more information on these or for general enquiries, please email Dr Aoife Braiden, geophysics ucd.ie.

To apply for the position, please forward a CV and cover letter to Dr Braiden (geophysics ucd.ie).

DESCRIPTION OF WORK:
The goal of the project is to analyse and develop models of surface deformation associated with subsurface magma movements and their connection with thermal signals. The selected candidate will join the crustal deformation group at IES in measuring and modelling deformation associated with eruptions and magmatic intrusions. The goal of the project is then to evaluate in particular what surface deformation signals are anticipated in response to temperature variations related to such sources and the associated heat transfer. Collaboration with other NEMOH members, including secondments at other NEMOH laboratories, will involve evaluation of fluid-rock interaction and inverse analysis.

WORKING ENVIRONMENT:
The successful candidate will work for three years towards completion of a PhD at the Institute of Earth Sciences, University of Iceland; a leading institution in the field of volcanology. The candidate is expected to complete a PhD within a research group including experts on volcano deformation, geothermal activity and volcanism. T

REQUISITES:
Candidates are expected to have background in geophysics or related fields and must meet the following requisites: 1) any nationality, but not having resided or carried out their main activity (job, studies, …) in Iceland for more than 1 year in the past 3 years; 2) no more than 4 years may have passed since completion of the degree that in their country gives access to a PhD; 3) not having completed a PhD. Current PhD students can apply.

DESCRIPTION OF WORK:
The goal of the project is to study and develop models of heat transfer from magma and hot rocks to the surrounding country rock. This will include analysis of existing data from case histories of geothermal signals associated with magma movements, the enhancement of conceptual and physical understanding through application of analytical models by exploring parameters and studying the links between deformation signals and thermal signals. In-depth studies of thermal signals will be performed using numerical models such as TOUGH2. For ice-covered volcanoes, ice flow numerical models may be used to quantify the thermal signals.
