Laser Strainmeters

Long-baseline laser strainmeters (LSMs) use a laser to measure the change in the relative position of end monuments hundreds of meters apart. These very stable and high-precision instruments measure strain change from months to decades and are an important tool for cross-validating long-term GPS/GNSS measurements and monitoring stored energy near a major fault.
