James Lindsey, 3 Midas House, Calleva Park, Aldermaston, Reading RG7 8EA, United Kingdom

Güralp has been producing revolutionary broadband seismic instrumentation for more than 35 years. Designed and manufactured in the United Kingdom, our seismic sensors and data acquisition systems are used worldwide by academic, public, governmental and commercial organisations to understand and explore our world. Güralp analogue and digital instruments record seismic events and signals of all kinds, from teleseismic events occurring on the other side of the planet, to microseismic events such as those induced by human activities (e.g. hydraulic fracturing). Applications include local, regional and global earthquake research; early warning systems; volcanology; structural health monitoring; energy exploration and optimisation; and induced seismicity monitoring. Güralp high fidelity digitisers ensure that seismic signals are recorded with the highest resolution and accurate timing required for research applications. For risk management and emergency response requirements, they offer industry leading low-latency functionality meaning data processing and transmission can be achieved in record times.

We have a programme of continuous development, investing in new ways of engineering our precision technology into smaller and more advanced casings that can be deployed in the harshest of environments. You will find our instrumentation employed around the globe, from the Antarctic ice sheet; to bore-holes hundreds of metres deep; to the world’s most active volcanoes and deepest ocean trenches.

Seismology Research Centre

Adam Pascale, 141 Palmer Street, Richmond VIC 3121, Australia

The Seismology Research Centre (SRC) was founded in 1976 as an earthquake monitoring and research group in RMIT University before moving to private industry in 1998. Specialising in structural, microseismic and regional monitoring networks, from the outset the SRC has developed earthquake data processing and management software, as well as developing their own seismic recorders, with the user experience and simplicity considered as high a priority as the technical capabilities of the systems. Operating an observatory with around 100 stations over an area of almost 2 million square kilometres, the SRC has serviced the water, dams, energy industries for over 40 years. With unique developments such as the Quick Quake iPad app, the Gecko seismograph and eqServer, SRC is dedicated to innovation to enable earthquake researchers and emergency managers to concentrate on their tasks, not on data management.
