Hawkes Bay beach erosion blamed on climate change in active earthquake zone

This NZ Herald story “One summer left: On Haumoana’s beachfront, the climate-change hourglass is ticking” clearly blaming “climate-change” for the loss of beach front houses. The article fails to mention the areas frequent earth tremors from seismic activity, 8 quakes moderate and stronger just to the south in the last 10 months, nearby mapped active fault scarps and the area is liquefaction prone.
Is it a surprise that periodic shakes & tremors from a variety of quakes should weaken the poorly consolidated shoreline sediments beneath the foundations of these unwisely sited houses?

  1. I grew up in Hawkes Bay. The foreshore has been eroding for decades. Ask the Ocean Beach surf life saving club where their original clubhouse is – it was abandoned about 25 years ago due to beach erosion. Similarly, Napier’s main beach, the Marine Parade whose extension runscto Haumoana, is no longer swimmable, if it ever was (can’t believe I used to swim there) due to erosion.

  2. The area certainly has an active history of uplift and subsidence –

    “1931 Hawke’s Bay earthquake
    On 3 February 1931, most of Napier and nearby Hastings was levelled by an earthquake. The collapses of buildings and the ensuing fires killed 256 people. The centre of the town was destroyed by the earthquake, and later rebuilt in the Art Deco style popular at that time. Some 4000 hectares of today’s Napier were undersea before the earthquake raised it above sea level. The earthquake uplifted an area of 1500 km2 with a maximum of 2.7 m of uplift. In Hastings about 1 m of ground subsidence occurred.”

  3. Ditto the erosion of the loess-capped mini cliffs in Timaru that saw a council coastal road collapse into the tide. I suspect the engineer involved had never done a course in engineering geology 101. Much easier to blame sea-level rise due to climate change.

  4. > ” … the engineer involved had never done a course in engineering geology 101″

    Why should he ? Living on multiple, active fault lines is not relevant to climate change. Is it ?

    As one may gather, I have despaired quite a while ago.

    If McKibbin (ANU, RBA) is quoted accurately in his recent co-authored report on the “Paris Agreement”, he regards “carbon emissions” (whatever they are) as general pollution. When that sort of rubbish is spouted by an academic economist, you know the Enlightenment is down the memory hole. Feelings win, ok ?

  5. The Great Ocean Road is apparently disappearing because of “climate change” according to these articles referring to erosion of the road near Apollo Bay on the Victorian SW coast:

    www.theage.com.au/national/victoria/great-ocean-road-at-risk-from-surging-sea-20190110-p50qjb.html

    The 9 News article shows a picture of the 12 apostles (I think only about 8 or 9 of the originals remain) near Port Campbell with the caption:
    “sections of the iconic Victorian surf coast could be falling away with rising sea levels and flooding contributing to dramatic erosion.”
    The coast in that area is limestone kast topography, where the coastal cliffs have been eroding for many thousands of years.

    The Age article quotes “Climate Change” Minister in the Andrews Government, Lily D’Ambrosio making the most of the opportunity to promote her climate alarm message:
    “Sea level rise is already considered in our long-term planning for the coast and we’ve invested more than $33 million to prepare for its impact.”
    “We know that climate change will cause rising sea levels – that’s why Victoria is on the path to net zero emissions by 2050.”
