Lessons Learnt From Mw 7.8 Gorkha (Nepal) Earthquake
Nepal is highly prone to earthquakes and has witnessed at least one major earthquake in 80 to 90 years interval. The Gorkha earthquake, that measured 7.8 RS in magnitude and struck Nepal on 25th April 2015, was the largest earthquake after Mw 8.3 Nepal Bihar earthquake which had occurred 81 years ago. In this paper an attempt has been made to highlight the lessons learnt from the MW 7.8 Gorkha (Nepal) earthquake. For most buildings, the construction and structural deficiencies have been identified as the major causes of failure, however topography, local soil amplification, foundation settlement, liquefaction associated damages and buildings builtin hazard prone areas were also significantly observed for the failure or damages to buildings and hence are reported. Finally, the lessons learnt from MW 7.8 Gorkha (Nepal) earthquake are presentedin order to mitigate impacts of future earthquakes in Nepal.
