The 120th anniversary of the eruption of Mt Tarawera on the 10th June 1886 was widely remembered earlier this year.
Vulcanology was poorly understood at the time, so it’s not surprising that a series of events which had occurred 5 years earlier were not fully appreciated, despite being widely reported in the nation’s newspapers during 1881.
Maintaining the manual toll boards of the 1970s was moderately labour-intensive. Installation obviously involved considerable labour, as circuits were hard-wired to modules which were repeated at regular intervals around the board. However, once installed, the various components were highly reliable considering the mechanical forces involved in day-to-day operation.
After several weeks of steady rain and a serious flood event, the southern Wairarapa area is still drying out.
Did your lights give you that sickening lurch that hints at a plunge into darkness at about 10:35 last night?
A deep earthquake near Golden Bay was felt throughout the lower North Island and upper South Island early this afternoon, according to data supplied by Geonet.
Gisborne telephone subscribers dialling “0” in the late 1970s were often struck by how bright and crisp the ringing tone sounded when compared with the sound heard when calling friends or neighbours.
Wellingtonians are shivering under yet another southerly blast today. July 2006 looks set to make additions to the weather record books, with the regional council announcing that new July rainfall records may be set in both Wairarapa and Wellington.
In Tawa, the first twenty days of July have been wetter and colder than the entire month last year.
The Gisborne TMX (Toll Manual Exchange) was located on the first floor of the “new” exchange building in Read’s Quay when I worked there in the late 1970s.
In keeping with the ‘design for expansion’ philosophy of the time, the “toll room” (as we called it) was a huge well-lit room with Post Office standard linoleum flooring. Entering through the double doors near the top of the stairs, a visitor walked past the Toll Manager’s office and across an expanse of floor with the ubiquitous metal lockers to the left, past a few well-tended pot plants to the toll board and supervisors’ desks. On the right, near the supervisor’s desks were the standard time-book desks where staff signed in and out as they carried out their shifts.
Earthquake activity continues at a low level. Mt Ruapehu, White Island, Raoul Island continue at Alert Level 1. Change at Mt Ngauruhoe.
Geonet, the USGS (NEIC) and IGNS reported 33 earthquakes in the New Zealand area between the Kermadec Islands in the north, and the Auckland Islands to the south during June 2006. The magnitude distributions were as follows:
M6 to 6.9 (none), M5 to 5.9 (2), M4 to 4.9 (17) M3 to 3.9 (11).
An additional 3 events in the magnitude 2 range were deemed worthy of mention.
Tawa’s climate during June 2006 was colder and wetter than the same month in the previous three years.
Weekly inflows to New Zealand’s hydro storage lakes were erratic during June, being below average during week 1, above average for weeks 2 and 3, and below average during the last week of June. This trend continued into July, with inflows being 82% of average in the week ending July 7th.
Despite this, lake inflows remained above those for the dry years 1992 and 2004.
Four earthquakes with magnitudes between 3.5 and 5.8 struck various parts of New Zealand in the 11 hours to 10 a.m.
Hydrothermal activity at Raoul Island has continued, but at a low level, since the March eruption according to a media release from GNS Science.
Earthquake activity near Fiji and Tonga has continued at moderate levels since the magnitude 6.0 event of June 27th.
