As part of the Kaikoura rail and road rebuild, Jenlogix were commissioned by KiwiRail and NCTIR with the installation of the cost effective Palert Seismometer system to help provide warning of earthquakes in that region. The Palerts array circles Kaikoura. Jenlogix also provides data feeds from other clients’ units in the Christchurch and Wellington regions. Sites include Hanmer Springs (Visitor Centre and Spa), St Arnaud (DOC Visitor Centre and Rotoiti Lodge), Blenheim (Marlborough District Council), Kaikoura Council as well as KiwiRail's own sites in the region.
Costing from $2,850, each device ensures the system did not break the bank, while still providing valuable asset protection and potentially lifesaving data.
The customised "live" data enables KiwiRail operations centres to better manage risk, enabling them to contact trains as appropriate. KiwiRail and Jenlogix also make the data available to GeoNet.
Secure servers take KiwiRail and other clients data to create a shakemap within seconds of a quake. In addition, SMS text alerts are sent to KiwiRail and other interested parties.
A breakthrough study by Taiwan National Chung-Hsing University, Departmental of Civil and Environmental Engineering, has proven that the health of a structure can be accurately diagnosed by using only 3 seismic units. Analysing data from a large number of units over a number of earthquakes, the university was able to prove the ability of this new methodology to accurately show the health of a building. The system calculates the rigidity and actual displacement to provide rapid structural health diagnostics (RSHD). This greatly reduces the cost to determine building safety and also helps engineers to rapidly assess the health of the structure enabling companies to return to work as soon as possible in undamaged buidlings.
