2006 WPGM GA in Peking, China

Western Pacific Geophysics Meeting (WPGM), Beijing, China, July 24-27, 2006


  WPGM meeting was organized for the first time in Beijing, China and took place in the Beijing convention Center. A 
special session was organized under on the Tectonophyscs section titled " Observation, Methodology, and Theory 
of Electromagnetic Signals Associated with Earthquake" and chaired by Q. Huang (Peking University, China), D. 
Ouzounov (GMU, USA), L. Telesca (IMAA, Italy) and T. Nagao (Tokai University, Japan). Session activities include 
poster session with 14 presentations and three oral sessions with totally 17 oral presentations. All poster and oral 
sessions all papers were divided into five topic groups:
 
EM regional studies and monitoring
  Earthquake-related electro-magnetic studies and its future development in China (J. Qian), Multi-geophysical and 
multi-geochemical monitoring of earthquakes in Yunnan-Sichuan region, China (Q. Huang), ULF magnetic transfer 
function approach for monitoring of crustal activity (K. Hattori), The comparison of the neutral current and the 
conventional telluric current measurements in Japan (T. Nagao) and MT study at the southern Boso peninsula 
Japan (I. Takahashi).

Geoelectrical Studies
  Geoelectrical investigations in seismic active areas: state-of-the-art and future challenges (V. Lapenna), The 
polarization feature of geoelectrical field before strong earthquakes (X. Zhang), Monitoring of the underground 
electrical structure change by using the wavelet-based electromagnetic transfer function (M. Harada), and New 
technology of georesistivity observation and its application at earthquake precursor monitoring (P. Zhang).

Satellite and Space related studies
  A statistical study of seismo-ionospheric precursors (J. Liu), Emitted long wave radiation variability from IR 
satellite data prior to major earthquake (D. Ouzounov), Correlation between time-specific solar activity and 
subsequent earthquakes (K. R Schulenberg), and Analysis of GPS/TEC variations associated with large earthquakes 
using GAMIT (K. Hattori).

Lab experiments and sensors
  Self-potential anomalies of rocks under biaxial compression (J Hao), Study on electromagnetic radiation response 
of stress state in coal body (L Zhongh), PS-100 anti-interference precision earth-electricity observation system 
and geoelectric resonance waves triggered by tidal forces prior to larger shallow earthquakes (Y. Zhao), 
Electromagnetic radiation law before rock burst (W. Enyuan), Numerical tests on electro-magnetic emission of coal 
or rock under process of uniaxial compression loading (Z. Enlai) and The antenna design in receiving EME during 
fracture of coal or rock (H. Daen).

Models and analysis
  Principal component analysis and singular spectrum analysis of ULF geomagnetic data associated with 
earthquakes (K. Hattori), The record principle and anomaly features of ULF electromagnetic disturbance (W. Xiao), 
Statistical modeling (tests) of the relationship between precursory phenomena and earthquake occurrences (J. 
Zhuang),
Statistical analysis of ULF magnetic data and magneto telluric transfer functions data for the 2004 Parkfield 
earthquake (K. Kappler), Mathematical modeling of the electromagnetic radiation by rock fracturing in physical 
simulation experiments (B. Wen) and Chaos characteristics of shock bump and its significance in predication (W Jing).

  Widely presented topic during the all sessions was the MDCB-5 precursor monitoring approach. Six posters were 
prepared by Chen I-wan, W.Yang, W.Wang, L. Wang, et al. from Califas Consultants, Ltd, Beijing. They consider that 
the new developed EM sensors, methodology and monitoring approach deliver weekly forecast for the major 
earthquakes in the Asian region.

  After closing all presentations Q. Huang opened the floor for discussion and ask all foreign participants what are 
their advices to the EM science community in China. D. Ouzounov (USA) proposed to the session to make a 
collection CD with all oral and poster talks CD in PDF format and delivery to each speaker; to work towards more 
close cooperation with seismology and Tectonophysics communities, in order to achieve a progress in the 
earthquake monitoring/forecast topic; to succeed into the new Seismo-electromagnetic Chinese satellite mission, a 
joint work is needed between ground EM and ionospheric science groups to be able to integrate and validate both 
approaches into a common project for earthquake forecasts in China. T. Nagao (Japan) proposed that future work 
should be focused on the developing a comprehensive model to explain the nature of the different EM precursors 
and their relationship to the earthquake preparation process. K. Hattori (Japan) and V. Lappena (Italy) both 
concluded about the importance of ULF/ELF ground network measurements for future earthquake monitoring in 
China. Q. Huang (China) made the final conclusion about the session dedicated to the EM phenomena related to 
earthquakes organized in China and thank to all for their participations.
