Another large earthquake has hit New Zealand.

A 7.5 earthquake hit the South Island, at Cheviot near Christchurch, just after midnight. Multiple quakes have since followed in both islands.

Talkback Radio has been hot on the topic of alerting, or more to the point, the lack thereof.

This week we are beginning a campaign to promote the use of TSUNADO as the best method of alerting the public when such disasters occur. This was in response to MCDEM issuing a statement that they were only supporting systems based on the cellular network. TSUNADO disagrees with this approach, as it was an option written off early on in the development of the TSUNADO System as being too fragile, to unreliable, and too costly.

Prepping for the Improbable


“The odds are better than Lotto that we're going to cop a tsunami at some stage. And it's not going to be nice.”

Prophet of doom, scaremongerer? Neither, says Gary Benner, who is developer of the tsunami alert system called Tsunado.

“During normal times it's just a radio,” says Gary. “But in the event of a disaster situation like a tsunami, it will let you know in no uncertain terms.”

Gary says he's a realist with a genuine desire to save lives.

NZ technology gives better warnings of disasters

An innovative New Zealand-made product is set to give people improved alerts and information about emergencies.

When a disaster such as a tsunami or volcanic eruption happens, the Tsunado, a compact plug-in alert radio unit, sounds a loud alarm before tuning into a Civil Defence radio broadcast.  It will soon be available for use in homes and offices.

The Tsunado is made by Disaster Warning Systems Limited (DIWA), who received funding and mentoring from Callaghan Innovation.

On September 3rd, 2015 an earthquake, 7.1 in magnitude, 130km north-east of Te Araroa at a depth of 55km at 4.37am - was felt from Northland to Wellington in the North Island, and in the top of the South Island. Severe reports were felt in Gisborne and the Bay of Plenty.

The earthquake prompted a large response from Civil Defence. Tsunami waves measuring 30 cm were picked up at Gisborne port and the gauge at East Cape.

There were numerous complaints that people did not hear any warning, or that the delays in issuing warning were unacceptable.

As usual, Civil Defence advised people to seek higher ground, and take a radio with them.

TSUNADO Alert Radios have the capability to not only provide news and information from local radio stations, but be activated to sound an alarm that will wake anyone in the house during the night, or above the usual noise of everyday life.

Because the turn on automatically when there is news to be delivered,  TSUNADO Alert Radios have a battery life of 5 to 10 days.

In remote regions such as East Cape, the signals can be delivered via the Optus D1 Satellite used by both Sky Television and Kordia (Freeview). This ensures 100% coverage to all regions of New Zealand.

Tsunado technology made possible with government funding

A new life-saving technology has been developed with the help of New Zealand government funding. Developed and manufactured in New Zealand with the assistance of Callaghan Innovation, this new product is now on its way to be commercialised for the use in offices and homes. The Tsunado was developed by New Zealand company Disaster Warning Systems Limited (DIWA).

$260,000 in government funding supports disaster management technology

During the stages of research and development, Callaghan Innovation provided a total of $260,000 in funding to DIWA. Not only did the government ogranisation provide funding, but also served as a mentor to the company by providing technical and marketing solutions and expanding their network of useful sources. The Tsunado product provides users with improved information and alerts about natural disasters. This product is a compact alert radio unit with a plug-in design. When a natural disaster occurs, such as an earthquake or volcanic eruption, the radio sounds an alarm then self-tunes into the nation's Civil Defense radio broadcast. According to Tsunado inventor Gary Benner, this idea occurred to him when he heard news of the 2004 earthquake and tsunami and simultaneously had his smoke alarm set off.

Tsunado technology now ready for purchase in New Zealand

Natural disaster emergencies can now be dealt with in a more organised manner with the assistance of this new government-funded technology. The Tsunado is now readily available to be pre-purchased on the company's website. This disaster management technology is already showing strong potential for exporting overseas. The Tsunado is also battery powered — which is useful in power outage situations — therefore allowing authorities to communicate important information to people in need. By providing funding for the development of such technology, the government continues to support innovation and protect individuals from natural disasters.




Callaghan-funded tech gives early warning when disaster looms

A Kiwi-developed disaster warning system has been given $260,000 by the government's innovation body Callaghan Innovation. The Tsunado alerts people to natural disasters like tsunamis, forest fires, tornados, floods and ...

TSUNADO Trial in Waihi

TSUNADO is currently participating in a Trial in Waihi with mining company Newmont Waihi Gold, and local radio station Gold FM, who brought the idea to TSUNADO after working with us on a Civil Defence pilot.

The current blasting programme causes vibrations which may cause some alarm. To mitigate this, TSUNADO Alert Radios are being employed to provide a gentle advanced notification prior to the blast.

This is from the Newmont Newsletter:

We have been told by some residents that the ‘startle effect’ of a blast
vibration is more of a concern than the vibration itself. For some, the sudden
and unannounced arrival of blast vibration is more of an issue. While the
vibration may be no more than a big truck passing, with a truck you can
hear it coming and you know what it is. There is no ‘startle effect’.
In an effort to reduce this effect we will soon be conducting a blast
notification trial. This trial with a selected group of residents will involve the
use of a Tsunado warning device. Originally designed for use in Civil Defence
emergencies, the Tsunado has been modified for our specific purposes. The
Tsunado is about the size of a small tea cup, and it plugs into an ordinary
power socket. It receives a signal from our underground shot firer about 30
seconds before a blast. On receiving the signal it will play music, quietly at
first, then rising in volume. The idea is that quiet music playing will advise
that a blast will follow, thus reducing the‘startle effect’. After the blast a series of
‘radio pips’ will signal that the blast has been completed.

Innovative Partnership in Emergency Management and Public Alerting

CLOUD M and Tsunado NZ are delighted to announce a new joint approach to public alerting solutions which will see the development of an innovative relationship to help promote resilience and safety for all New Zealanders.  

CLOUD M built and delivered the Auckland Civil Defence & Emergency Management (CDEM) alerting platform and native mobile phone application (Alerter) with in excess of 50,000 registered users.  This has been successfully operational for the last two years and is currently being considered for national use. Alerter helps the CDEM agency alert the public of emergencies, keeping them informed of emergency response, and helps prepare them to cope during a disaster. It also helps the public take care of themselves and each other. It connects close friends and loved ones in a secure, private network, and helps households develop and manage household emergency plans. 

Tsunado NZ has developed a unique public alerting system known as TSUNADO, which has been built to provide geo-targeted alerts across the country, using satellite and FM radio to distribute the alerts.  TSUNADO  continues to receive information even when there is no power, mobile or internet availability.   

The system uses simple, unobtrusive Alert Radios  placed in the home, which sound a warning (similar in loudness to a smoke detector).  The Alert Radios display a text message to the user, and then automatically connect to an audio feed from a local radio or satellite TV station to provide further information.  With inbuilt rechargeable batteries, authorized information is able to be continually received for up to five days after an emergency event.The TSUNADO devices replace the need for a battery operated radio, which is an essential component of every recommended emergency survival kit.
