A volcanic alert was issued last night on White Island, near the Bay of Plenty, following an increase in minor tremor levels.

Meet Molly Ambrose, 10-year-old Taranaki schoolgirl and the world’s youngest-known volcano chaser.

Is it any wonder Auckland Council is having a hard time selling the Unitary Plan to the rest of us?

Seismic activity is continuing at the Popocatepetl volcano near Mexico City and authorities say they have readied shelters and identified evacuation routes in case they should be needed.

Sweeping views of Auckland's volcanic cones risk being violated by new planning rules, critics say.

To geologists perhaps, six years is nothing, writes Brian Rudman. But for those of us on human time, it seems an inordinate amount of time to need to hatch the plan.

Rangitoto may be much older - and more explosive - than previously believed.

A new discovery that shows that Rangitoto erupted "semi-continuously" for about 1000 years is prompting scientists to re-think what the volcano could do in the future.

Giant craters found on the sea floor off the South Island coast may be the world's biggest pockmarks, say scientists.

As they did on the afternoon of March 17, tens of thousands of Aucklanders take to Facebook and Twitter to express their amazement that their seemingly quake-free city has had a rumble.

A supervolcano forming north of New Zealand could spell the end of the world - but there is no need to panic, it won't happen for at least 100 million years.

The nzherald.co.nz visited White Island in February 2013 as tourists who are continuing to flock to the volcano are fascinated by the up-close views as the island continues to produce "vigorous bursts" of mud, rock steam and gas up to 100m high.

White Island has been spewing mud and rock several tens of metres into the air in the past few days, as GNS Science warns of a greater risk to visitors.

New Zealand's most active volcano is primed to blow again, just days after scientists thought it had calmed down enough to lower alert levels.

Unsettled activity at White Island, which has prompted authorities to raise alert levels, indicates the volcano could erupt at any moment.

Hydrothermal activity at White Island has increased and experts say there is "significant concern" the volcano could erupt with little or no warning.

Fireworks are believed to have been responsible for a large fire in the crater of Auckland's Mt Eden early this morning.

New Zealand scientists are hoping to capture new deep-sea species when they head out to one of the world's deepest undersea trenches this week.

The steam and super-heated gases which have been pouring from the side of Mt Tongariro since two surprise eruptions last year are set to be a feature for years.
