Welcome to Canterbury Seismic Instruments
Superior Seismic and Structural Monitoring Solutions
Canterbury Seismic Instruments had its origins during the mid-1990s in the world renowned earthquake engineering group at the University of Canterbury in New Zealand. It was officially established in 2003 as a fully independent company to commercialise the innovative CUSP range of seismic monitoring equipment.
Since then the company has expanded its range of instruments to become a leading international supplier of new generation, quality strong-motion and structural monitoring equipment.
This instrumentation has been shown to be invaluable in providing real data in a major earthquake so that critical infrastructure could reopen rapidly and safely to speed up the emergency response. Following the devastating Christchurch, New Zealand, earthquake of February 22, 2011, the instrumented section of the Christchurch International Airport, was able to reopen within 20 minutes, which was crucial for access to aid for the city.
Customised Structural Monitoring Solutions
Combining measurements of a wide range of parameters provides a better picture of a structure’s health. Canterbury Seismic instruments has expert knowledge in this field and provides customised solutions using a multi sensor structural monitoring system linking to a wide range of input types. Our sensors can record data related to strain, acceleration, displacement, wind, water depth, pore-pressure and more. This knowledge and ability to meet individual requirements is highly valued by clients throughout the world.
The seismic instrumentation has been extensively tested and proven under active conditions in Iceland and more recently in 2010-2012 with more than 10,000 earthquakes and aftershocks in Christchurch, New Zealand.
The use of industry standard technologies and open communications and data formats ensures maximum compatibility with existing infrastructure and data processing systems. In many cases existing Ethernet wiring can be used for rapid deployment at a fraction of the cost of alternative suppliers systems. Engineer-friendly interfaces and data formats reduce operator effort and advanced features such as global triggering, data streaming and a powerful web-based interface further enhance the CUSP-3 and CUSP-M ranges.
For Use By:
- Soil structures vary depending on location, so measurements taken at other sites can be misleading. Actual measurements are useful for an engineer when deciding if a building is reacting according to the building model or demonstrating a weakness.
- Measuring real-time data on movement, strain and other measurements of the health of a building or infrastructure may be related to the question: ‘Does the structure react the way the building model predicted?’
- An actual measurement of the stress or strain experienced by a building or infrastructure during an earthquake or other significant event may be related to such questions as: “Has this building been exposed to more stress than it was designed for? Is it safe to occupy? Is this dam at risk?
Building and Infrastructure Owners and Managers
- It is useful to have real data from the site available immediately to base decisions on.
- An instant measurement (internet or text) can assist in determining building safety for occupants, related to such scenarios as:
- The movement exceeded the building limits – get everyone out immediately.
- The movement was within the calculated building tolerances – business as usual.
- The movement was in between these levels – get an engineer to physically inspect the building
