Towards a Redefinition of the National Geodetic Vertical Datum by the Integrated Geodesy Adjustment- A Viewpoint [PDF]

open access: yes, 1992
Determination of Mean Sea Level (MSL) as a vertical datum for orthometric heights is a vital requirement for the readjustment of the National Geodetic Levelling Network. The vertical datum is defined to be the geoid whereby it's practical realization was

Stability analysis of points in geodetic monitoring networks using the MINQUE method and the weighted similarity transformation

open access: yesRevista Técnica de la Facultad de Ingeniería, 2010
In the analysis of geodetic networks used for monitoring deformations, there are two baste aspects to consider. One is the correct estimation of the weights of the observations, and the other is the correct Datum definition.

How Significant is the Dynamic Component of the North American Vertical Datum?

open access: yesJournal of Geodetic Science, 2012
One of the main current geodetic activities in North America is the definition and establishment of a geoid-based vertical datum that will replace the official CGVD28 and NAVD88 datums in Canada and the USA, respectively.

Mode of Strain Release Associated with Major Earthquakes in Japan [PDF]

open access: yes, 1973
It is now widely accepted that most shallow earthquakes are caused by a sudden release of tectonic stress, and therefore strain, in the form of faulting (56, Chap. 14).
