May I point out that the last Weekender insert featured an imagined mega-thrust tsunami that is the stuff of Hollywood disaster movies. Comparing the wave pictured with Tuamotu Island (36 metres high), Young Nick’s Head (177 metres) and the distant shore hills, this monster would have to be an absurd several kilometres high! Recent scientific studies have estimated the height of a magnitude 9 mega-thrust tsunami to be anywhere between 12m and 30m. The article itself seem liked another handout from council, patting itself on the back for its new civil defence building and its exercise. Information on what the public could do in such an event would have been relevant — but if a 30-metre tsunami wave rolls in, even the new Civil Defence building at Lytton will not be safe.
