Recent Kaikoura Quake gave 19 seconds warning to a resident of Wellington.
Despite being only a single unit with no link to other warning devices, the unit reacted to the Pwave, giving what turned out to be 19 seconds warning of the shock wave. This enabled him to get his family up and into a safe area where they could duck, cover hold. Initially there was thought it was a fasle alarm as it took so long, but certainly not after it arrived.
Taiwan 5 Seconds
In Tawian, , the recent 6 Feb quake contained a killer pulse that destroyed buildings and while the national system provided warning this takes a few seconds, but the local onsite units provided vital 5 seconds warning, well ahead of the central system.

WANT TO KNOW IF CONSTRUCTION IS DAMAGING YOUR BUILDING - INSTANTLY?
MAKE SURE YOUR BUILDING IS NOT BEING AFFECTED BY LOCAL VIBRATION FROM CONSTRUCTION OR OTHER EVENTS
Construction, demolition or even heavy traffic can often cause unforeseen problems to neighbouring structures due to vibration. With the launch of the Palert+ Vibration monitoring system, building owners and users can now INSTANTLY get feedback on any issues with vibration.
Palert+ is a simple system to monitor the impact of this vibration on your building. With just a single Palert+ unit and an attached multi-coloured light, you can instantly see if the nearby work is causing any impact. Using international vibration standards DIN 4150-3 or ISO 2631, the system can ensure protection for your building. It can be used to make sure that the contractors are not exceeding vibration levels and meeting their compliance requirements.
Data is also sent directly to the cloud for engineers to see remotely the issues and direct construction accordingly. Being cloud based the engineers can assess the issue and inform the contractors of any remedial action required, even to the point of stopping construction. There are often heavy fines imposed on companies if vibration limits are exceeded.
So do not be caught out by damage to your building due to excessive vibration, when the simple Palert+ solution can instantly provide feedback.

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.
SAVE TIME AND MONEY BY ASCERTAINING THE SAFETY OF A BUILDING RAPIDLY AFTER AN EARTHQUAKE
Prompted by the recent Kaikoura and Christchurch earthquakes, Callaghan Innovation purchased the cost effective Palert earthquake warning system to help improve staff health and safety. Installed by Jenlogix partner, Red Wolf Security, the system is installed in the offices of Callaghan in Wellington and Christchurch, providing warning of earthquake shock waves before they arrive, switching off/on emergency systems, and triggering visible and audible alarms, enabling staff to potentially exit the building before the destructive wave arrives.
Data from the system is sent to a central server, hosted by Red Wolf in their secure data centre, for processing. Combined with data from additional units in Wellington, Christchurch and other locations, the server can provide shake maps of the earthquake normally within a minute of a quake occurring. The data will also be sent to engineering firms to enable rapid determination of the health of the buildings after a severe shake.With over 3,000 units installed worldwide, the Palert P-wave seismic alarm system has proven itself at helping provide early warning where possible, plus supplying valuable data on the effects of an Earthquake. All products in the Palert range are independently calibrated and certified by an internationally ISO approved testing laboratory.
The breakthrough technology of the advanced, cost effective, Palert system can give you that warning and the chance to act before the main devastating shock wave arrives. A P-wave of an earthquake is like seeing lightning before hearing the thunder. Alternatively the Palert can be used to protect key assets. Even without any early warning the Palert can be used as a local Earthquake Detection System to manage local assets.

In Greenland such a quake caused a tsunami. Could that happen in NZ? That's a very good question.

Team granted funding to plan response for Alpine Fault megaquake
A megaquake along the Alpine Fault with the potential to "unzip" the South Island happens roughly every 300 years - the last one was in 1717.
The Government has put together a team of scientists and civil defence experts to investigate the possible 8.0 magnitude quake, which could tear chasms in the ground, cause landslides, damage state highways and topple cellphone towers.
The Ministry of Civil Defence and Emergency Management has granted them $490,000 to create a high-level response plan within two years. For more info see link

Where Wellington hides its water
It holds as much water as an Olympic swimming pool, and can withstand the mightiest earthquake.
