The US State of Oregon has developed a new series of landslide maps showing susceptibility of their highway network to a large scale earthquake. see http://phys.org/news/2015-02-outlines-western-oregon-landslide-subduction.html
In NSW we don’t have an up to date Engineering Geological map of our State’s capital. It is long overdue for a series of detailed Engineering Geology maps to be produced for the states larger population centres!

Interesting results on new sources of NOA from Nevada. It would be worth looking at similar igneous systems in Australia.
Mesothelioma in southern Nevada likely result of asbestos in environment
Date:
February 10, 2015
Source:
International Association for the Study of Lung Cancer
Summary:
Malignant mesothelioma has been found at higher than expected levels in women and in individuals younger than 55 years old in the southern Nevada counties of Clark and Nye, likewise in the same region carcinogenic mineral fibers including actinolite asbestos, erionite, winchite, magnesioriebeckite and richterite were discovered. These data suggest that these elevated numbers of malignant mesothelioma cases are linked to environmental exposure of carcinogenic mineral fibers.

The WordPress.com stats helper monkeys prepared a 2014 annual report for this blog.
Here’s an excerpt:
A San Francisco cable car holds 60 people. This blog was viewed about 1,500 times in 2014. If it were a cable car, it would take about 25 trips to carry that many people.

We have been acting as the lead trainers for RMS Guide to Slope Risk Analysis Ver. 4 training since 2012 (Marc has been involved with the slopes program since the early 2000s). Accreditation for completion of training is through courses conducted by NSW Roads and Maritime Services.
Contact Marc to discuss your training needs.

Marchgeo provided design and supervison for cutting rehab works on the Summerland Way north of Kyogle in August. The video below just one of a number of large rocks removed. Risk now down to ARL4!

Marc attended the International Rockfall Protection Conference 2014 hosted by Geobrugg in Switzerland and Austria over May 21 to 28, 2014. The conference included a field test of Geobrugg’s 500kJ flexible rockfall protection canopy at their testing facility in Wallenstadt. Following technical talks a tour was held of remedial sites in Switzerland, Austria and Southern Germany. Among the numerous installations visited was the large rock fall canopy along the spectacular Route des Pontes, in the Canton of Valais:
The tour provided invaluable information about state of the art slope remedial works.

Slope Stability 2013 will provide a forum for open pit mining and civil engineering practitioners, consultants, researchers and suppliers worldwide to exchange views on best practice and state-of-the-art slope technologies. Best practice with respect to pit slope investigations, design, implementation and performance monitoring will be discussed during the symposium.
The ACG is delighted to host this symposium in Brisbane for the first time. Past symposia have been held in Vancouver, Canada, 2011; Santiago, Chile, 2009; Perth, Australia, 2007; and Cape Town, South Africa, 2006.
We are attending this Friday

We are currently assisting RMS with slope stabilisation works at Clyde Mountain on the Kings Highway. The area has a long history of landslides driven by a coincidence of road geometry and bedding. Widening works in the late 1950s undercut bedding dipping steeply into the road way leading to the current problems. Failures occurred during widening (1959-about 30,000m3), in 1993 (about 5,000m3) and last year (April 2012-about 1000m3).

We have added a new SRA page that will be expanded to include more detail about our SRA, and slope risk management capabilities Marc Hendrickx and Associates are the best choice for independent advice on slope risk management.
