New Zealand's Tongariro National Park volcanoes produce hazardous eruptions every few years to decades. On 6 August 2012 the Te Maari vent of Tongariro Volcano erupted, producing a series of explosions and a fine ash of minor volume which was dispers

High voltage station and line insulators are vulnerable to volcanic ash-induced flashover, yet little quantitative data exists on the environmental, volcanological and electrical parameters most influential in reducing their flashover voltage. This p

The pollution severity of airborne contamination on high voltage insulation has traditionally been quantified by calculating the contaminant's equivalent salt deposit density (ESDD). Volcanic ash is a rare but severe form of airborne pollution, and t

Modern society is highly dependent on a reliable electricity supply. During explosive volcanic eruptions, tephra contamination of power networks (systems) can com- promise the reliability of supply. Outages can have signifi- cant cascading impacts fo

Volcanic ash contamination of high voltage (HV) power networks compromises the reliability of society's electricity supply. Ash-induced insulator flashover is a common problem on transmission networks dur- ing explosive eruptions, which is attributed

Volcanic eruptions can produce a wide range of hazards. Although phenomena such as pyroclastic flows and surges, sector collapses, lahars and ballistic blocks are the most destructive and dangerous, volcanic ash is by far the most widely distributed
