New Seismic Sensors Improve Earthquake Resilience

Published: 29-Nov-2018

Waimakariri District Council has partnered with local company Canterbury Seismic Instruments (CSI) to install seismic sensors across the District.

These sensors will help improve the management of earthquake effects on buildings and infrastructure following an earthquake.

Two sensors will be in Rangiora, and one in Cust, Oxford, Woodend, Mandeville and Kaiapoi giving effective district wide coverage.

Having site specific shaking data removes uncertainty in immediate post-earthquake decision-making and emergency response activation, as the sensors measure earthquake ground shaking providing critical, location specific, real-time information to the Council in the event of an earthquake. The information is also instantly available for emergency management teams.

CSI General Manager Len Damiano says, “Our initial roll-out of more than 150 sensors across Christchurch is virtually complete. CSI is now very pleased to be collaborating with Waimakariri to deliver a more seismically resilient future for the whole region – not just Christchurch.”

While seismic equipment in itself is not new, CSI’s lessons from the Canterbury, Seddon and Kaikoura earthquakes have been instrumental in the development of EQRNet – CSI’s online platform that compares ground shaking to the building code demands of any structure.

The sensors will provide an ongoing source of data about ground motion across the whole Canterbury region, which engineers, research organisations and authorities can use.

“In an earthquake we need immediate, useful data on the impact across not only our major cities, but across whole regions; defensible decisions from reliable information. This benefits everyone from private individuals to business to critical infrastructure”, explains Dr Hamish Avery, CSI’s Chief Technical Officer.

“EQRNet is a new and unique way of delivering this; a global first making Canterbury the most seismically prepared region in the world”.
