Güralp surface instruments are trusted by seismic network operators, research institutions and industry specialists worldwide for their proven reliability, exceptional sensitivity and ability to deliver high-quality seismic data in a wide range of environments.

Designed for both permanent network installations and rapid temporary deployment, our instruments combine precision sensor technology with robust, compact and portable designs, making them suitable for installation in buildings, vaults, shallow pits and direct-burial applications.

Low self-noise, wide dynamic range and advanced environmental protection ensure dependable measurement of ground motion, from subtle microseismic activity and distant earthquakes to significant local seismic events.

Our surface systems are used extensively in national and regional seismic networks, earthquake and aftershock monitoring, volcano surveillance, induced seismicity monitoring, geothermal energy, carbon storage and seismic exploration.

Whether establishing a long-term monitoring station in a remote location or rapidly deploying a temporary network following a seismic event, Güralp provides the performance, flexibility and confidence needed to capture reliable data in the field.

Our broadband sensor range spans the full seismic spectrum, providing solutions for virtually any monitoring requirement.

Our medium-motion sensors feature adjustable responses for greater flexibility, making them particularly well suited to instrument pools and variable deployment requirements.

For applications that need to capture signals at both ends of the spectrum, our dual-sensor solutions combine weak- and strong-motion capabilities in a single instrument, delivering comprehensive seismic data from one installation.
