New ‘any angle’ Radian posthole and borehole seismometer launched at EGU, Vienna

Güralp, the leading global provider of force feedback seismic monitoring instrumentation is launching a new generation, feature-rich, subsurface seismometer that delivers ‘plug-in-and-go’ installation for boreholes up to 2000 m deep and shallow posthole applications.

The Radian is a broadband, triaxial, digital seismometer designed using a state of the art sensor that means it can operate at any angle. This capability combined with its compact form; unique data capture and instrument management features makes it ideal for rapid and temporary seismic deployments, especially in areas of high cultural noise.

Phil Hill, Engineering Director at Güralp explains the design approach to the Radian:

“We understand how dramatically noise performance improves with deployment in the subsurface, but it can be time consuming and expensive to undertake. With the Radian we set out to design an instrument that would provide the sub-surface broadband coverage the geophysical community wants, but in a much more accessible ’plug in and go’ package.

Because the Radian operates at any angle, installation times are significantly reduced – for example, posthole instruments can be installed with a hand auger and checked for integrity with the Bluetooth Android App in a fraction of the time and cost it would take to construct a sub-surface vault.”

How the Radian works:
The sophisticated sensor inside the Radian allows the masses to operate at any angle, the Surface Interface Unit (SIU) receives data from the Radian’s internal magnetometer and MEMS accelerometer to optionally realign sensor data to true geographic orientation.

The SIU delivers Ethernet data communication and can also be accessed via Bluetooth Android App to check installation integrity without physical disturbance. Further instrument management features include dual redundant MicroSD card storage for hot swapping without data loss and; streaming of instrument response and calibration parameters in Dataless SEED format.

Güralp is exhibiting the Radian on stand 18 at the European Geosciences Union General Assembly in Vienna, Austria all this week (18 -22 April). If you are attending please make time to visit our stand. Engineering Director Phil Hill and the Güralp team will be on hand to show you how it works and answer any questions you have.

NOTES TO EDITORS:

Güralp (www.guralp.com) is a leading global provider of sophisticated seismic monitoring solutions used to understand natural seismological events such as earthquakes, aftershocks and volcanos, as well as induced seismic events, or seismic signals, resulting from human activity.

Our solutions are used in research, civil and industrial applications to increase understanding, optimise processes and to protect people and the environment. Our equipment is installed in all major ocean basins and across all continents worldwide.

Our instruments range in performance from very low frequency, very low noise for global seismology to high dynamic range instruments for local, strong motion monitoring. Our sensors and can be supplied for deployment at the surface, in boreholes and on the ocean bottom. We also provide data acquisition equipment, power and communication accessories and data interpretation software.

Our services include installation and commissioning; network operation; repair and maintenance services; data processing and interpretation.

Headquartered in Reading, in the UK, we have been operating for more than 30 years and have established a global network of distributors who provide local customer support and sales services.
