Earthquake recording instrument
The type M.O.2. strong motion accelerograph
Recognising that the only practical method for obtaining the primary data on earthquake resistance in large structures is to measure their behaviour during earthquakes, the Department of Scientific & Industrial Research realised there was a need both in New Zealand and overseas, for a low-cost, strong motion earthquake recording instrument suitable for use in multi-storey buildings and other important civil engineering structures.
