flank, causing fires in the native bush which swept 3km northwards across the western slopes of the Pouakai Range (Druce, 1970, cited in Neall, 2003). 150 years later a pumice lapilli fall and pyroclastic flows covered Maori villages, inferred from the discovery of Maori ovens (umu) beneath the deposits. In 1755 A.D. small hot avalanches occurred from eruptions at Taranaki. Recent evidence from Platz (2007) suggests that the most recent eruption was between 1839 and 1866 A.D., and potentially in
January 2022 rainfall
The year began with Taranaki's second driest January ever, with none of our monitored sites getting even a third of their normal rainfall for the month. Totals ranged from 8% to 29% of normal, with an average of 17%, and our monitored sites recorded rain only on three to seven days during the month. Stratford recorded just 13.5mm, its lowest January total since records began in 1998. Our monitored sites on Taranaki Maunga recorded 17% to 23% of their normal Janary rainfall, with rain on five to

relation to best practice irrigation onto high and low risk soils. 1.6 Application Depth The volume of water applied during irrigation is referred to as the application depth. Farmers will make reference to the amount of rain in their rain gauge in mm. For example, there was 4 mm of rainfall yesterday. This relates to the formula 1mm of rain falling on 1 ha equals 10,000 litres. Using the example of 4mm of rainfall, this would equate to 40,000 litres of rain falling on each ha of land.

for municipal and rural water supply. Did you ever wonder why many rivers have water in them when it hasn’t rained for days or weeks, there’s no snow melting, and the ground is dry? The rivers are being filled up by water coming from out of the ground in the form of springs and seepages which brings us on to the topic of groundwater. Groundwater facts Groundwater is water which occurs in formations below the earth’s surface. In Taranaki we use 44,022m3 per day but recharge
