In this study we compare modeled and observed spectra from earthquakes and non-earthquake sources to instrument self-noise and models of global background signal.
Here the results of the performance testing are reviewed, interpreted, and compared with other co-located instrument types including the venerable STS-1. We also present the Trillium 360 roadmap, with a smaller low-power version for ocean bottom and portable land deployments in development for 2022.
An instrument system that provides high-gain weak motion data in precise alignment with strong motion data at a single point in
bedrock allows combined processing to create a seamless data set with maximum dynamic range.
The Pegasus Data Acquisition System is an ecosystem of hardware and software components for portable seismic monitoring that fundamentally transforms how seismic campaigns are conducted. This integrated ecosystem-based approach to seismic data acquisition ensures that campaigns areeasy to plan,…
These new instruments expand our range of products enabling new ocean bottom science, reducing integration risk and time to deploy, while improving outcome certainty.
This study examines the factors considered, the approaches taken and the outcomes in the design and
implementation of a real time acquisition system for the Israeli National EEW Network, TRUAA.
Practical management of induced seismicity risk and effective mitigation approaches are crucial to oil and gas operations.
The magnitude of completeness (Mc) of a seismic network is determined by a number of factors including station density, self-noise and passband of the sensor used, ambient noise environment and sensor installation method and depth.
We compare predictions of network performance to observations made from an earthquake catalogue. We estimate event spectra using Brune modeling and station noise to predict the magnitude of completeness for a network.
Low latency is a key contributor to the success of an earthquake early warning (EEW) system. There are several points where delay is introduced between the instant in time that a digitizer produces a set of samples across its analog sensor channel inputs and the point at which the corresponding…
