Tawa’s weather for the three weeks to June 21st has been colder and wetter than last year.

Ngauruhoe Volcano – Update

Wednesday, June 14th, 2006

New Zealand’s Mt Ngauruhoe volcano was recently upgraded to alert level 1 (some signs of volcano unrest) by GNS Science, following shallow low frequency earthquakes in the past month.

The upgrade was a precautionary measure, as the low frequency earthquakes occurring at the volcano can indicate increased movement of volcanic fluids or magma. As part of the upgrade decision, GNS Science decided to undertake additional monitoring of the volcano.

GNS Science issued an alert bulletin based on recent observations late today indicating that activity at the volcano has eased slightly.


Town & Country

Tuesday, June 13th, 2006

Yesterday’s twin dramas, a massive power failure in Auckland and a solid dump of snow in the South Island, highlight the great divide between town and country.

There are some excellent lessons to be learnt by every New Zealander from both incidents, but it seems likely that they’ll be lost in the acrimonious debate that is already evident as business, politicians and the usual anti-Auckland lobby fire up.

GNS Science announced the raising of the Alert Status at Mt. Ngauruhoe to Level 1 (some signs of unrest) via its Geonet website this afternoon.

The status change results from a significant change in the number and magnitude of low frequency earthquakes being recorded by seismographs around the mountain during the last three weeks.
