Interactive Map: Track where the ash might go

Track likely ash clouds from Mt Tongariro using this simple interactive map.

This map shows the likely flow of ash cloud when the winds are blowing from certain directions.  Generally speaking winds this week will be light from the westerly quarter.

At the time of the eruption (1:30pm, Wednesday) winds were blowing from the SW at just 13km/h.  Using our interactive maps below you’d select both southerly and westerly quarter to see the regions impacted (although mostly the westerly quarter map will be relevant this week).

Winds are light at the moment – so any ash movements will be slow.

This is irresponsible and inaccurate. The only sources for credible volcanic ash information are GNS, the CAA and
You may despise the Met but they are the authority and are actually qualified to produce and disseminate this type of information.

Hi Doug,

This isn’t irresponsible – it’s a basic guide for the general public.  We don’t despise MetService – we have issues with them charging for content the public has already paid for.   This is a very basic guide and has helped the public – if MetService want to make these graphics and make them easy for everyone to read then we will publish those instead.  At this stage they don’t provide a service for the everyday public with ash – only technical information for airlines. 

Kind regards

Philip Duncan
