  • It was identified after the post Oruanui highstand and Lake Huka outlines were prepared from more recent sources that they had likely used some of the data represented in Figure 8 of Manville, Vern; Wilson, Colin J. N. (2004). "The 26.5 ka Oruanui eruption, New Zealand: A review of the roles of volcanism and climate in the post‐eruptive sedimentary response". New Zealand Journal of Geology and Geophysics. 47 (3): 525–547. doi:10.1080/00288306.2004.9515074.. This article also has B/W photographs that help in landscape orientation. Accordingly this source appears important to add.

Additional information This data is used on several relevant articles which are listed under source in case a minor reference gets missed. The controlling logic was added after initial upload and it is no longer pure json data. The logic now excludes the display of the Reporoa Caldera at this time on any default call (so its invisible when this page itself is displayed). Also invisible on a default call are immediate post Oruanui eruption Lake Taupō and Lake Huka data. However if needed this could be made accessible by adding further page control logic. The dataset has potential associations where in future such manipulation may be useful, without creating duplicate datasets. There is:
  1. A map of approximate outline of the single event 280 ka Reporoa Caldera, North Island of New Zealand
  2. Approximate contour mapping for area of the historic Reporoa lakes and maximum extent of Lake Taupō after the Hatepe eruption
  3. Lake Huka that preceded the Oruanui eruption

It is likely to get heavier traffic w.r.t. the later Lake Taupō addition so logic is arranged with this as default call. The maximum extent of the first Lake Reporoa, that may have lasted a decade odd is likely to be more inaccurately mapped than the maximum area of the second transient lake. This only lasted a week odd at most and is known to have filled to the 303m above sea level, likely towards the start of the Taupo outlet Hatepe flood event down the Waikato River. The contour line for maximum height Lake Taupō at 35m above present lake level after the Hatepe eruption is reasonably accurate although an unfortunate rendering artefact happens at zoom 9 due to floating point rounding errors which is not seen on default thumbnail. The maximum height of the lake after the 26 ka Oruanui eruption was just under 500m above present sea level. The contour lines for Lake Huka that preceded the Oruanui eruption, reflect that at one stage it was about 400m above present sealevel but it almost certainly had a slightly higher high stand at some time historically. While a transient Lake Reporoa existed shortly after the Oruanui eruption it would be impossible to map this from the data available, although the high stand was probably similar to that after the Hatepe eruption and the intermediate stand was about 330m above current sealevel. A subpage key was not been created for inclusion but if it is needed suggest use page ->Wikipedia:Map data/Reporoa Caldera/key.
