Strong Motion Accelerograph Requirements for Australian Dam Safety
Strong Motion Accelerograph Requirements for Australian Dam Safety
A dam in a low-seismicity area can still require seismic instrumentation if the downstream consequence category is high enough. This article explains what ANCOLD requires from strong motion accelerograph installations... Read more...

Choosing a Strong Motion Accelerograph: 5 Key Decisions
The sensing is largely solved; what separates a better instrument today is everything around it. Five decisions that decide whether the accelerograph you specify is still useful, and still yours,... Read more...
