The SGL crew eco-commute

Most of the SGL team members are now eco-commuting to and from our offices each day. In order to reduce our impact on the environment our employees are choosing to travel using a selection of alternative transport options including cycling, E-bike, E-scooter and carpooling. Eco-commuting is not only a great thing to do for the planet, but it is more cost effective and the open-air options are great for health and well-being. SGL and our employees are always looking for ways to reduce our enviro...

The far corners of New Zealand

In the past few weeks, Southern Geophysical's concrete scanning and NDT team have worked in some of the more remote corners of New Zealand, from spillways in the North Island to the depths of Fiordland. They've tackled some adverse weather conditions, and tricky terrain. Accessing narrow lift shafts, tunnels, and dams requires confined space qualifications, the ability to work on rope with abseil teams, and experience operating 4WDs and ATVs. Getting to the sites is just the start of the day for...

South Island Japanese Strong Motion Network 7 years old and going strong

Since 2011 Southern Geophysical has maintained and supported the Japanese Northern South Island strong motion seismic network. The network which now contains 54 stations was installed just after the Canterbury Earthquakes and has been operational ever since. Several stations were lost in the Kaikoura Earthquake but were rapidly replaced.  Thee network data is being analysed by a team of Japanese seismologists to allow a more detailed understanding of the New Zealand tectonic regime which ha...

Maintaining Seismic Networks

Southern Geophysical Limited has been working with Kyoto University's Disaster Prevention Research Institute for over five years now. Researchers from the university installed a network of seismographs to observe earthquake activity in the upper South Island. Southern Geophysical assisted the researchers with establishment of the network, and now look after and maintain the network from year to year. Every maintenance run requires over 2000 km of driving and trekking to some of the most remote c...
