In June, a team of CEDIM researchers analyzed the impacts of the earthquake in Nepal on April 25 in a two-week field mission. The main focus of the field mission was shelter after the earthquake. With a survey on household-level, the researchers investigated vulnerability to being displaced, information needs and decision processes to seek shelter. During their field mission, the CEDIM team with Dr. Bijan Khazai, Dr. Susan A. Brink, and Trevor Girard from the Karlsruhe Institute of Technology KIT and Johannes Anhorn from the Southasia Institute, Heidelberg University, closely collaborated with their colleagues of the National Society for Earthquake Technology (NSET) and of the Earthquake Engineering Research Institute EERI.

CEDIM has been analyzing the earthquake and its impact since April 25th. . The results of the near-real-time analyses are published in several reports.
Report 1 - Status April 27th 2015 20:00
Report 2 - Status May 5th 2015. Focus on shelter response and vulnerability of displaced population
Report 3 - Status May 12th 2015 16:00
Report 4 - Status July 17th 2015
Preferred Hazard Information
Preferred Hazard Information
Intensities reached VIII on the MMI scale – very well built structures received slight damage. Older buildings suffered great damage. There was also limited liquefaction and many landslides. The epicentral damage seen corresponds to VIII and perhaps very isolated VIII-IX locations on the MMI scale. Over 50 aftershocks > Mw4.7 have occurred, with magnitude 5 and 6 earthquakes continuing to pepper the region east of the epicenter. The fault sense can be seen easily from USGS, Chinese and Geofon data, with the fault break running parallel to the Himalayas toward Kathmandu. At least 60 aftershocks have been strong enough to be felt. A triggered earthquake occurred on the 12th May 2015.
Vulnerability and Exposure Metrics (Population, Infrastructure, Economic)
Nepal has a net capital stock around $39 billion USD with approximately 28.8 million inhabitants. In terms of capital and GDP it is an extremely poor nation with less than $700 (USD) GDP per capita in 2015. It is mountainous in nature and has the chance for many landslides. Kathmandu and the Central and Western regions are key tourist areas for Nepal among others with the area accounting for 5% of GDP through tourism (direct/ indirect). The Kathmandu area has a GDP slightly higher than the rest of Nepal. The direct epicentral region has a lower GDP per capita in comparison. Agriculture (outside Central) and trade are the key components of GDP.
Population distribution across Nepal per ward.
What have been the 2 largest comparable damaging events in the past? None exactly in this region.
