On July 30th (2018), 2 additional MEMS type accelerometers were deployed at the same locations (basement-center and top of theatre-north wing) of available force-balance type accelerometers. Fully equipped domestic accelerometer station AREL DAC3-5D includes 3-component MEMS- SD©1521. It has a noise level of 5 µg. and a dynamic range of ± 2 g. Resilient communication was guaranteed between Site- BU.
