Presiden IAG - Harald Schuh

Presiden IAG bagi sesi 2015-2019 ialah Prof Dr Harald Schuh dari Germany. Schuh adalah Director of the GFZ Department of Geodesy. Schuh memperoleh Ph.D dari University of Bonn pada tahun 1986 dengan tesis doktoral beliau ‘VLBI for the determination of station displacements and Earth rotation‘.

Pada Februari lalu Schuh berkunjung ke Universit of Tehran di mana beliau menerima lantikan sebagai Adjunct Professor. Pada tahun depan (2018) Schuh dan GFZ akan mengadakan workshop of geodesy and geophysics di Tehran University.

Prof Deakin - myGeodesy

Prof Deakin (RMIT) menyediakan satu website khusus yang beliau namakan myGeodesy. Berbagai nota kuliah dan bahan rujukan berguna meliputi berbagai tajuk dalam geodesi dan least squares ada di sana. Antaranya termasuklah nota tulisan tangan tentang the Earth gravity field dan juga the normal gravity field.

Selain subjek geodesi dan LS turut dimuatkan ialah bahan mengenai map projection, transformation dan survey computation.

Chapter on Modern Geodesy (2009)

A special textbook on geodesy was published by Springer in 2009 entitled "Global Geodetic Observing System". The book consists of many contribution chapters by re-known geodesists and was edited by Plag.

Chapter 2 is a good read on "the goals, achievements, and tools of modern geodesy" with seventy-five pages content.

Deformation Examples (cont'd)

Following are more case examples of deformation - hydro dams failure;

Rempen (1924); Gleneau (1932); Stava (1985) - all in Europe; San Fransisco (1928) and Teton (1976).

Cases of Stava, San Fransisco & Teton lead to the establishment of standards for deformation survey since 1920s.

Another case of deformation which was highlighted most is Turtle Mountain Alberta. Seventy people perished and the deformation was caused by geological structure and excessive coal mining.

Example on cases of deformation

There were a number of deformation cases reported in the last thirty years or so. Following are among the notable one;

1. Teton Dam (1976) with 11 casualties and 20,000 live stocks.

2. Mountain side near Shin Tan collapsed into Yang-tze River (1984). No casualty (why?). Extensive monitoring exercises; such failure correctly predicted; evacuation takes place one week prior to incident.

3. Zeuzier Arch Dam, Southern Switzerland - continued deformation disclosed abnormalities in 1978 (after 20 years in operation).

The lessons learned - it is worth of investment for society. What is needed? - instrumentation & procedures/methodology; software; expertise. [k-economy = dedicated professionals]. It is not a side-line venture (why?) prone to misleading outcome; wrong interpretation because without knowing overall situation/requirement/rigor]
