On Saturday, 25 April 2015 6:11UTC, an earthquake with a magnitude of 7.8 and a depth of 15km struck Nepal affecting 6.5 Million people within 100km (cf.GDACS).  Several aftershocks have occured since then, notably a 6.6. magnitude aftershock about 30min after the initial earthquake and a 6.7 magnitude aftershock on Sunday 26 April 2015 at 7.09UTC (cf. JRC Situation report No.1). To support the response to the disaster, several actors are involved in producing useful information. UN-SPIDER compiles this information here to make it easily accessible.

This page is constantly being updated. If you are aware of additional information, please contact the UN-SPIDER team at and we will include it in the list.

Needs and Areas of Interest

  • The Humanitarian Open Street Map Team (HOT OSM) has identified areas that need high resolution imagery for both base mapping and damage assessment. The team stresses the urgent need for cloudfree imagery directly north of the Kathmandu valley, as these areas are still cut off from any relief/aid. Areas requested by HOT OSM are highlighted in bright blue on this map:
  • Experts on the ground in Nepal recommend moving towards assessment of damages in small towns and villages, mapping of landslides which may block rivers as well as to asses road accessibility.
  • Areas of focus as requested from the ground in Nepal include monitoring of lakes (see Excel table and kmz file for their location).
  • The maps produced by Micromappers, MapAction, and Humanity Road contain information regarding data and information needs (cf. below under Crowdsourcing Community).
  • GDACS LiveMap includes under GDACS satellite mapping coordination areas of interest that are completed, in progress, and planned. It is also intended to provide an ongoing record of satellite image analysis results over Nepal from different sources including COPERNICUS, UNOSAT, and NGA. All results are preliminary and unverified. Imagery Sources: International Charter on Space and Major Disasters; Analysis Sources: UNOSAT, NGA. (cf. link to GDACS LiveMap).
  • The Epicenter of the Earthquake was located at 28.26N  84.66E (cf. CSEM EMSC).

Satellite-based Emergency Mapping

  • Last year the EU satellite centre elaborated products over Kathmandu including image maps based on satellite imagery over the city and the airport and an Index Card book including all the information available related to Medical Services in Kathmandu. An Emergency Web Portal was generated by the EU SatCen, on Kathmandu potential crisis evacuation. This service includes features related to the location of the EU Delegation, EU embassies and other international delegations (non-EU countries and UN), hospitals, police stations, large hotels, some important governmental buildings and possible helicopter landing sites, main transportation hubs (airport) and open places that could be used for evacuation purposes. It is possible to access and Download the products by double clicking on the SATCEN logo: (user: kathmanduadm; pasword: kathmanduadm%)
  • Copernicus EMS Risk and Recovery Mapping was activated for Nepal in 2014 to prepare for the big earthquake. A large amount of maps were produced:

Crowdsource community

  • TOMNOD Nepal campaign. Help disaster response teams by mapping damage from the recent deadly 7.8 magnitude earthquake that hit near Kathmandu, Nepal. Start by comparing before and after imagery and placing a tag in the center of every damaged building, damaged road and area of major destruction you find. To compare before and after imagery, press the "Q" and "W" keys on your keyboard or click the "Newest" and "Oldest" buttons in the bottom right corner of the map. See TOMNOD results here.
  • HOT OSM. 3679 mappers have made 62587 edits to the map (statisitcs as of 30 April 2015). (link to OSM Wiki including link to OSM task manager)
  • Micromappers. Analysis of images and text from tweets. (link to image crisis map, link to tweet crisis map)
  • MapAction. Maps on affected population.
  • Humanity Road. Situation reports including communities in need.
  • Overview on crowdsource mapping activities for the Nepal earthquake at iRevolutions.
