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.

Should we protect the views, writes Brian Rudman, or slip in a few apartments as some act of reconciliation. Is it any wonder the majority of councillors have doubts.

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.

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.

White Island is just the tip of a submarine mountain that rises a staggering 1.6km from the sea floor, its fiery innards sealed shut from the surrounding Pacific Ocean.

The closest you will ever get to lava going into the ocean, Kilauea Volcano on Hawaii's Big island puts on an amazing show on 10. Filmed from a helicopter and boat at extremely close range, so close that the ocean was boiling. Filmed by Breaking News/Geoff Mackley.

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.

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.

Plumes of "smoke" seen rising from Mt Tongariro today are not signs of increased volcanic activity, say GNS scientists.

The volcanic alert level at White Island has been raised to 2 and the aviation colour code to orange.

Taupo's mayor has criticised the response to Mt Tongariro's eruption this week, calling it an overreaction and saying we need to "learn to live with a live volcano".
