Ground motion measurements in Kathmandu

A single U.S.G.S. NetQuakes instrument was installed in Kathmandu with help from John Galetzka (now at Unavco) and the U.S. State Department several years ago. It has recorded the main shock and has triggered on many aftershocks. The peak acceleration at this instrument’s location during the Main Shock was less than 0.2g, however, PGV as processed by the Center for Earthquake Strong Motion Data exceeds 100 cm/s and according to  Susan Hough (USGS Pasadena) the peak vertical displacement was ~1.5m. Location of the instrument is ~27.71N, 85.315E (Instrument meta-data).
