Question Does seismic activity on Mauna Kea effect the operation of the telescopes there? Asked by: Captain Darryl Welch Answer Mauna Kea is a dormant volcano. Seismic activity is much less of a concern than wind. The summit of Mauna Kea is home to a dozen or so world-class observatories. The largest, and most well-known is the Keck Observatory. According to their official website: 'On the telescope, each segment's figure is kept stable by a system of extremely stable support structures and adjustable warping harnesses. During observing, a computer-controlled system of sensors and actuators (or precision pistons) adjusts the position of each segment - relative to its neighbors - to an accuracy of four nanometers, or 1,000 times thinner than a human hair.'
