**************************************************************************************************************
Dear Colleagues,
2011 IUGG General Assembly will be held from June 28 to July 7, 2011 at Melbourne.
We would like to warmly invite you to contribute to one the following sessions related to electromagnetic phenomena related to active processes.
Please note important dates:
- Abstract deadline is January 17, 2011.
- Early bird registrations deadline is April 11, 2011.
Yours Sincerely,
EMSEV Inter-Association Working Group ( http://www.emsev-iugg.org/emsev/)
======================== Session 1 ============================
J-S09 Electromagnetic Studies of Earthquakes, Active Faulting and Tsunamis
Organisers: IASPEI, IAGA, IAVCEI
Lead Convenors: M. Johnston (United States of America), T. Harinarayana (India)
Lead Convenors: M. Johnston (United States of America), T. Harinarayana (India)
Scope: The realization that earthquakes, aseismic fault failure and tsunamis generate electromagnetic phenomena has been the subject of intense interest during the past few years. Crustal phenomena may arise directly and/or indirectly from source processes driving these tectonic events and may reflect the roles of fluids in active faulting. Unfortunately, not all aspects of these measurements, or theories proposed to explain them, are well understood. Tsunami effects arise from the movement of conducting seawater in the Earths’ magnetic field. This symposium will focus on the following four main areas of investigation:
- Measurements of electric and magnetic fields near active faults and with tsunamis
- Controlled laboratory observations and observations from natural laboratories such as locked faults, slipping faults and stress from dam loading/filling,
- Theoretical considerations regarding source generation mechanisms.
- Measurement resolution, data quality, identification separation and removal of spurious signal sources.
Each of these areas provides insight into, and quantification of, electromagnetic fields generated by earthquakes and tsunamis.

J-S10 Electromagnetic studies of active processes using space technology
Organisers: IASPEI, IAGA, IAVCEI
Lead Convenors: M. Parrot (France), Y. Hobara (Japan)
Lead Convenors: M. Parrot (France), Y. Hobara (Japan)
Scope: Observations of electromagnetic phenomena associated with seismic and volcanic activities have been reported for many years. Perturbations occur not only in the lithosphere but also in the atmosphere and ionosphere, leading to the generation of a new science field, lithosphereatmosphere- ionosphere coupling. This session will accept papers dealing with new observational findings on the seismic effects with satellites. Contributions along the following lines are also encouraged:
- The TEC variation provided by GPS satellites,
- Coordinated satellite and ground-based EM experiments

- Coordinated satellite and ground-based EM experiments

J-S11 – J-V09 Imaging and monitoring active volcanoes and geothermal fields by ElectroMagnetic (EM) and other geophysical techniques
Organisers: IASPEI, IAGA, IAVCEI
Lead Convenor: J. Zlotnicki (France)
Co-convenors: Y. Sasai (Japan), V. Spichak (Russia)
Lead Convenor: J. Zlotnicki (France)
Co-convenors: Y. Sasai (Japan), V. Spichak (Russia)
Scope: Electromagnetic methods have been intensively applied to volcanic systems, hydrothermal and geothermal fields for understanding the structure and tectonic setting, and for monitoring the activity. Analyses of long time series undoubtedly show that magnetic and electric effects can precede volcanic eruptions, and geothermal activities. The development of new technologies and methodologies allows us to clarify the relationships among magmatic, hydrothermal, environmental and mechanical processes. Combination of land and satellite EM studies with other geophysical observations could also drastically improve the description and understanding of on-going processes.
The session will focus on the following lines:
- EM tomography and modelling of volcanic/geothermal environments,
- Integrated EM monitoring such as self-potential, magnetic, electric, magnetotelluric, combined with satellite observations,
- Joint EM, geochemical, thermal, ground deformation and seismic observations,
- Laboratory experiments and physical mechanisms of EM generation processes,
- Modelling of volcanic activity

J-S12 Towards short-term earthquake prediction - Electromagnetic and other possible precursors and their generation mechanisms
J-S12 Towards short-term earthquake prediction - Electromagnetic and other possible precursors and their generation mechanisms
Organisers: IASPEI, IAGA, IAVCEI
Lead Convenor: T. Nagao (Japan)
Co-convenors: Konstantinos Eftaxias (Greece), Friedemann Freund (United States of America)
Scope: It is generally believed that the achievement of the short-term earthquake prediction is very difficult. However, this topic is one of the ultimate goals of the solid earth sciences. Furthermore, to achieve short-term prediction, the unambiguous identification of precursory phenomena is essential. During the past few decades, there have been strong arguments about the reality of the existence of “reliable” precursory phenomena. In this session, we would like to focus not only on electromagnetic “precursors” but all suggestions of “reliable” earthquake precursors. Most important will be evidence showing clear uniqueness of these signals in the long-term record, relation to other independent geophysical data and their generation mechanisms. Thus, we would like to discuss the following topics from a critical points of view.
1) All kinds of evidences of precursory phenomena, involving seismic, geodetic, geochemical, hydrological, in addition to electromagnetic anomalies, and their inter-relationships.
2) Theoretical models and lab experiments to explain the physical mechanisms behind precursory phenomena.
3) Study of various data bases with new procedures (e.g. critical approach).

J-A04 Electromagnetic oscillations from space to Earth: Celebrating 150 years and recent developments in ultra-low frequency wave research
Organiser: IAGA Div.3 (To be co-sponsored by IAGA Divisions I, II, V, Interdivisional Commission on History and IASPEI)
Lead Convenor: Brian J Fraser (Australia)
Co-Convenor: Malcolm Johnston (United States of America)
Lead Convenor: Brian J Fraser (Australia)
Co-Convenor: Malcolm Johnston (United States of America)
Scope: The year 2011 marks the 150th anniversary of the first publication on the rapid geomagnetic fluctuations that are now known as the ultra-low-frequency (ULF) waves. This landmark observation published in 1861 by Balfour Stewart of the Kew Observatory near London commenced an ever-growing research field whose topics range from the connection between solar activity to upper atmospheric phenomena, the dynamics of the magnetosphere, and the electric conductivity interior to the Earth. These seemingly different subjects in fact share common observations and physics through ULF waves. This special symposium will celebrate the 150th anniversary of the discovery of ULF waves by bringing together not only historical aspects of ULF research but also newly developed observational and modeling techniques that promise further understanding of both space and terrestrial environments. Interests will be focused on the role of ULF waves in the solar-terrestrial and planetary sciences, the Earth sciences in the areas of wave generation and propagation processes, diagnostic techniques and applications.
