_The Evening Post_, 23 November 1923:
EARTHQUAKE SHOCKS
Reports received to-day by the Government Astronomer, Dr. C. E. Adams, show that the earthquake shocks experienced at #Otira on Wednesday morning followed one on another at intervals of three minutes, 5.13, 6.16, and 5.19 a.m., with a break then till 6.20, and 11 a.m., the movement being from north to south, and one of the shocks being recorded as lasting half a minute, the others having durations of three, two, three, and one seconds. The early morning shock was felt most generally, awakening those asleep and sending stones rolling down the mountains, but no damage was done.
A second examination of the #Wellington records showed that that shock reached Wellington at 5.14 a.m., and a telegram from #Christchurch reported a shake at 5.13. a.m. on Wednesday, so that probably the centre of disturbance was between Otira and Christchurch, at which latter place the movement was from east to west. The shake was generally felt by persons in motion in Christchurch, and disturbed moveable objects, without, however, doing damage, and it was apparent that the shake there was much more pronounced than at Wellington.
