Quake felt strongly at Dunedin 24.3.16 #eqnz

2:06 a.m.
My Pitt Street apartment went CRACK at its northeast corner as I watched TV. Nothing in the room moved except a miniature pohutukawa potplant, its long branches were swaying. Heard not felt, was it a quake ? Opened up GeoNet on my smartphone, confirmed. Completed GeoNet (felt) report.

    Some people open their mouths without thinking. All he needed to do was visit Geonet and have a quick look. Once I was living in a geologist’s home and I felt an earthquake during the night. It woke me. But when I reported it the next morning they did not believe me. The report of an earthquake came out in that day’s newspaper.

    We all know Dunedin has quakes, but that doesn’t mean that we should put ahead of all other precautionary projects, assessing and upgrading at-risk buildings. Seymour is right to imply that there are other risks that Dunedin should take more seriously. Upgrading its south Dunedin storm water system to accommodate the increased run-off due to the increased impermeability of its surfaces would be a start.

    This 1930s URM building I have lived at since 2003 catches most thumper quakes and aftershocks – it was designed by a Dunedin architect (well-known to my family, who commissioned him for another building in the late 1940s) who it seems had the tendency to not specify enough reinforcing steel for his buildings….

    ODT: Quakes wake North Otago residents
    North Otago residents were woken overnight by two earthquakes, centred 30km west of Oamaru.

    █ So YES. Let’s get our Dunedin buildings made safe as soon as we can. The Akatore Fault is our largest known fault line, but remember Christchurch…. lack of public knowledge – despite formal televised warnings – about underlying faultline systems.

    Quite a few searches at What if? Dunedin for Dunedin/Otago fault maps. These were published by Otago Daily Times along with their stories about Dunedin’s earthquake proneness, following the Christchurch quakes:

    TV1 Sunday – Wake up call
    What have we learned from the Canterbury quake? The seismologists tell us there’s a 60% chance of another magnitude 7 quake somewhere in the country within 10 years and a one in 10 chance of it happening within a year. Scary! It’s a wake up call, because if we don’t invest in earthquake proofing our old buildings, then people, are going to die next time – either fix them or pull them down is the advice. Is it scaremongering or is it a timely warming? Article: http://tvnz.co.nz/sunday-news/wake-up-call-3769479 Video: http://tvnz.co.nz/sunday-news/wake-up-call-3769479/video (9:04)

    3.9.10 Earthquake
    Dunedin’s Russell Garbutt contacted What if? this morning after news of the disaster in Canterbury. He says: At the beginning of the year I wrote a piece for publication and sent it to the Listener, North and South and New Zealand Geographic. The subject was earthquakes and what was likely to happen in the event of a major movement on the Alpine Fault. As it happens, I was talking to a member of the Geology Department on Friday and he had just returned from Christchurch and the Coast working on exactly that – he said on Wednesday that a major movement was due “now”.

    █ Most of us remember this 1996 documentary that screened on national television:

    11 March 2011
    Stuff: Documentary warned of Christchurch earthquake danger
    The director of a 15-year-old documentary outlining the effects of a major earthquake on Christchurch’s eastern suburbs and heritage buildings says lives could have been saved if officials had heeded the film’s warnings.
    An edited eight-minute clip of the 1996 documentary, Earthquake!, had received nearly 30,000 views on video website YouTube by last night. The documentary said Christchurch’s “fatal flaw” was the land that it sat on – “a soft, shaky sponge of riverstones and silt half a kilometre deep”.

    I thought it was a dream till I read whatif.

    I was reading in bed, missed it completely. Normally pendant lights swing but there was nothing like that, not a twitch, roll, jolt, shake or quiver.
