Tiltmeter and Crustal Deformation Programs

Last updated 18 May 2001; To be completed ???

Past tiltmeter projects: Aleutians and Southern California

Several reports are to be included someday .... In the mean time, look up the references on my "vitae" page, particularly the JGR article "Shallow Borehole Tilt: a Reprise".

The New Beam Balance Tiltmeter.

The current project is the beam balance tiltmeter funded in October 1999 by the NSF. The design is to detect pure tilt but not horizontal acceleration, so that local tilt noise can be removed from broadband horizontal seismic data.

The abstract for the 2000 fall AGU describes the project. A revised version of this poster was presented at the 2001 SSA meeting in San Francisco on April 18, 2001.

See the Latest Abstract on another page.

As time allows, I will post the entire poster presentation, including the figures and photos as I get time to scan them. You are encouraged to send me email to prod me along.

I have attempted here to present the text only of the poster. See the Poster text listing for the text.

I will eventually also include here some, if not all, of the detailed technical report on the instrument design and development, which I completed around 1 Oct 00. The report comprises 43 pages of text and 27 pages of figures and drawings.

A number of people have tried to read it, but the only feedback I have received is of the order: "Nice report.... well written .... as far as I got .... about page 5". I can only assume that since it was rather difficult and highly technical for me to write, it may be almost impossible for anyone else to read.


PATENT APPLICATION NOTICE: A patent application has been filed on the concepts and on various unique details of this Very Broadband Beam-Balance Tiltmeter (VBB-BBT) design. This has been done by St. Louis University in order to protect our rights to all aspects of the instrument, and specifically to prevent any third party from claiming any rights to it and preventing us from disseminating it under our control. I want to try to maintian open participation and contributions of everyone interested, rather than allowing a major company to secret it away and then charge us megabucks for it. Eventually we will have to arrange a cooperative agreement for someone to manufacture it.
