Volcanoes, Eruptions, Oh My!

Well the second half of 2012 has been all about the volcanoes! Tongariro and White Island in August then maybe Ruapehu, but no Tongariro again!

So firstly some important information on what to do during during an ash fall event and lava flows and general information for before/during/after an eruption from CDEM.

Where to find information on our website:

Current status of the volcanoes, drums and cameras here
News and Volcanic Alert Buletins here
More information and history on Tongariro here and our other volcanoes here

What do the alerts mean?

So what does this mean?

Unfortunately we don't know what will happen in the days to come. As far as eruptions go this was just a small one, only lasting five minutes. And there were no signs that Tongariro was going to erupt again today, volcanoes can be sneaky like that!

We do have lots of seismic sensors on and around the volcanoes and cameras watching the mountains as well as a great team of experts currently looking at all of the data coming in! So we will be closely monitoring the volcanoes and putting out bulletins as more information comes in.

View from Te Maari Crater shortly after the eruption.


  1. If I may ask a question here: Is Ngauruhoe showing any signs of unrest at the moment? I dont know much about the geology or science behind it, however I make it a point to browse the volcanic drums out of pure intrigue and have notticed that Ngauruhoe often shows tremmors(presumably), and these often appear isolated to that peak's drums only. Is this the case or could these be caused by rockfall or similar due to the steep angle of the mountain? Just interested to know.

  2. Hi Tristan - Ngauruhoe recently had a lot of activity on the drum due to a lightning storm! You can read all about the current activity on the volcano here:
