Trillium Horizon SeismometerIntroducing the Trillium Horizon

The latest addition to the Trillium 120 product line is one of our most versatile seismometers to date. This seismometer matches the portability and deployability of our Trillium Compact line with the performance of our vault seismometers. This dual-purpose instrument can be direct buried at shallow depth or set on a pier, meaning the Trillium Horizon gives you the most versatility for your investment.

As of August 2017 almost 5 years of data have been collected from broadband seismic sensors designed for direct burial applications. These first posthole instruments have been deployed in a wide range of extremely challenging environments such as dynamic ice and snow environments, extreme wet and dry conditions in soils of high clay content, and steep creeping terrain. In all use cases the direct burial approach has consistently provided high quality data when compared to shallow vault installations.

In this presentation we extract and analyze operational performance data, including tilt information from mass position time series recorded at direct burial installations and at temporary shallow vault deployments. This data shows that while higher tilt tolerance is required for data quality outcome certainty in some installations, the majority of installations can be addressed by a smaller instrument with a narrower tilt range hence reducing size and cost. The lessons learned from this real world field data have guided the development of a new smaller, less expensive instrument, Trillium Horizon.

Based on this analysis and and user feedback from many direct burial deployments, the Trillium Horizon seismometer has been developed as a simple versatile instrument to span the majority of deployment scenarios and specific use cases including shallow direct bury deployments, traditional piers, and problematic wet vault installs. With its small size, robust waterproof case and connector, +/-1.5° tilt range, dual-purpose cable, and accessories for both posthole and vault installation, Trillium Horizon is optimized for usability as well as performance.

In response to induced seismicity observed in western Canada, existing public networks have been densified and a number of private networks have been deployed to closely monitor the earthquakes induced by hydraulic fracturing operations in the region. These networks have produced an unprecedented volume of seismic data, which can be used to map pre-existing geological structures and understand their activation mechanisms. Here, we present insights gained over the past three years from induced seismicity monitoring (ISM) for some of the most active operators in Canada. First, we discuss the benefits of high-quality ISM data sets for making operational decisions and how their value largely depends on choice of instrumentation, seismic network design and data processing techniques. Using examples from recent research studies, we illustrate the key role of robust modeling of regional source, attenuation and site attributes on the accuracy of event magnitudes, ground motion estimates and induced seismicity hazard assessment. Finally, acknowledging that the ultimate goal of ISM networks is assisting operators to manage induced seismic risk, we share some examples of how ISM data products can be integrated into existing protocols for developing effective risk management strategies.

A Comparison of EEW Approaches: Challenges & Benefits

The primary objective of an earthquake early warning (EEW) system is to provide an advance notification of an on-going event before the arrival of damaging seismic waves to a target site. This requires a robust seismic network infrastructure, rapid event characterization algorithm and fast communication system. Most of existing EEW systems operate based on two different approaches: on-site and regional. The on-site approach uses first P-wave arrivals at the target site to estimate ground motion intensity at the same site for a local warning. As the warning is issued based on local measurements of P-waves, it does not require estimations of event location and magnitude for the prediction of ground motion intensity. The regional approach, however, benefits from very first detections at front-line stations and rapidly determines event magnitude and location to estimate ground motion intensity at distant target sites using a regional ground motion model. The estimated source parameters, which are continuously updated as more stations are triggered, allow estimation of ground motion intensities at multiple sites. This enables issuing strong shaking alerts at multiple sites as well as the generation of shake and loss estimation maps for post-event emergency response. Here, we examine the two EEW approaches in terms of their inputs and outcomes, with focus on the challenges to achieve a robust early warning system and benefits of data products for each approach.
