"Historically the mountain has had periods where it's done that," Taranaki's civil defence controller Shane Briggs says. On the scale of volcanic eruptions Taranaki last erupted fairly recently Scott says and the region has recovered well, but another eruption could take years, even decades to clean up. The last one was in 1655, so it's in the post. "If one were to happen at the start of winter, farmers would probably be ok, they have feed stored and the cows don't need milking. Taranaki's ring plain provides a rough clue to the extent of previous eruptions. "It's a massive misconception that it will erupt overnight." It's estimated that the volcano has erupted over 160 times in the last … ​"Serious eruptions will affect sunlight, turning days into nights, penetrating the soil surface and affecting photosynthesis which will in turn affect plant growth and the local climate.". While most people are unlikely to have volcano insurance, people with property damaged by any natural disaster can make a claim with the Earthquake Commission (EQC), as long as they already have some form of home and contents insurance. "Indirect effects are that livestock get respiratory diseases due to ash inhalation." Briggs predicts a host of similar problems could occur in a post-eruption Taranaki. The last major eruption of Taranaki occurred around 1854. "Any natural disaster is a massive task to clean up after, take the June floods for example, but in this case where would we put all the ash?". This is far greater frequency than previous realised. A big Mt Taranaki eruption could launch devastating pyroclastic flows across a wider area than first thought - putting more people at risk. The last major eruption was in roughly 1655, while a smaller ash eruption occurred 100 years later. It takes only three millimetres of ash to short circuit a powerline and with Stratford - and its power station - downwind of the predominant easterly wind Taranaki has numerous points of vulnerability. More concerning than the frequency of these eruptions, is that they have often occurred in swarms - semi-continuous eruptions over many years. The rapidly accumulating organic sediments within the lake were perfect for trapping ash layers from Mt Taranaki; in fact almost 100 ash layers were contained in the cores. Although the 2518m Mt Taranaki, New Zealand's second-highest volcano, has shown little or no sign of activity for two centuries, our new research suggests it has erupted at least once every 90 years on average for the past 9000 years, with a major eruption every 500 years. Recent research has shown that o… Each of the volcanic ash layers in the core are from millimetres to several-centimetres thick. The last … "It's one of those future occurrences that people don't think really think about, or what it could mean for their daily lives," he said. Taranaki is geologically young, having commenced activity approximately 135,000 years ago. These eruptions are large enough to shower New Plymouth with pumice and rock fragments the size of raisins, producing a deposit up to tens of centimetres thick. The largest known eruption of Taranaki in recent centuries was a major explosive (subplinian VEI 4) eruption around 1655. Plants could be covered in centimeters of ash following an eruption. However, he remains optimistic that when an eruption does finally come it won't be the end of Taranaki. A similar volcano-type, Soufrière Hills volcano on the island of Montserrat in the Caribbean, shows a present-day example of this type of activity, since it has been continually erupting for the past decade. However, it isn't all doom and gloom Briggs says a chain of eruptions is the worst case scenario, and there would have plenty of warning before an eruption of that type happened. Mt Taranaki is believed to last have erupted more than 200 years ago. Historically, Taranaki has had minor eruptions every 90 years or so with a major one thrown in every 500 years. David Lean, former Taranaki Civil Defence controller. GNS Science is New Zealand's leading provider of earth and geoscience research and its scientists monitor the mountain for earthquakes - the first tell tale sign the mountain is beginning to stir - but they can also map its past. Bradley Scott, volcano specialist at GNS Science. In Taranaki agriculture will grind to a halt as plants struggle to absorb sunlight and livestock won't be able to eat the grass buried under a thick carpet of ash. Mt Taranaki is overdue for an eruption by more than 100 years. "But if it were to hit now, after winter, it could be a very different story.".

Since the quake Canterbury has seen a 37 per cent increase in people seeking mental health services and police have seen suicide callouts rise more than 60 per cent. Lava has been recorded reaching up to seven kilometers from Mt Taranaki's peak, roughly the size of Egmont National Park. "It's a massive misconception that it will erupt overnight.". Between 1755 and 1800, an eruption sent a pyroclastic flow down the mountain's northeast flanks, and a moderate ash eruption occurred about 1755, of the size of Ruapehu's activity in 1995/1996. Because while the clean up from a single eruption would be an arduous task, there is a real possibility Mt Taranaki could erupt more than once and spew forth more ash periodically for years, destroying the regional economy. "Put simply it's not going to kill everyone. "But predicting where exactly any of this will fall or concentrate is impossible to tell until it actually happens. Detailed studies by scientists from Massey University have worked out the history of volcanic eruptions at Mt Taranaki over the last 130,000 years. The last, recorded in 1755 but possibly followed up with a further eruption in the early 1800s, formed the present cone on Taranaki. GNS has had monitoring equipment on and around the mountain since 1991 and they record around 250 earthquakes every year, but none related to the volcano. "In an eruption we can basically count on Taranaki being pretty much totally evacuated." "By studying the volcano's history through eruptive deposits we can gain an idea about how it could act in the future.". "What these guys are planning for is an event that hasn't happened here before within anyone's lifetime.". These data are to be used to develop probability models in order to forecast the chances of future events and help authorities and businesses to plan for the next one. While eruptions have not occurred at regular intervals, on average there has been a moderate-sized eruption every 340 years, with numerous small ones. A similar volcano-type, Soufrière Hills volcano on the island of Montserrat in the Caribbean, shows a present-day example of this type of activity, since it has been continually erupting for the past decade. Shane Briggs from Taranaki Civil Defence says all hope is not lost for the region when Mt Taranaki finally erupts. "Agriculture would be destroyed," he says. Mt Taranaki began forming about 130,000 years ago and moderate to large eruptions have occurred on average every 500 years with smaller eruptions occurring about 90 years apart. Overall, Briggs says he doesn't think people are prepared for an eruption.

While previous eruptions have made Taranaki's soil arable and renowned for its fertility, the immediate effects of an eruption would be disastrous for agriculture in the region. Thomas Wilson lectures hazards and disaster management at the University of Canterbury and says the psycho-social issues - like anxiety - are more of a concern in a scenario where the mountain continually erupted.
