Nepal is used to earthquake activity.

- A 1000 km fault line runs along the southern border (there is a convergent plate boundary) < Indian and Eurasian plate - creates the Himilayas.

- Earthquakes of a magnitude of more than 8 happen there. (intervals of 75-80 years)

The two plates are colliding ata a rate of 45mm per year

- In 2015 the Indian plate jumped forward about 2m

- The magnitude was high because the origin of the earthquake was close to the surface of the ground (shock waves have a shorter distance to travel).

Secondary Effects

  • The sahking of the ground triggered avalanches and landslides
    • Avalanches on Everest killed at least 19
    • Avalanche in Langtang left 250 missing
    • Landslide blocked river which meant that people living near the river had to evacuate (in case of flooding)
  • The earthquake happened on land so it did not cause a tsunami

Long-term responses

  • Roads repaired and landslides cleared
    • Lakes formed from damming river valleys need to be cleared to prevent flooding
  • Thousands of homeless to be re-housed and homes repaired
  • 7000 schools rebuilt or repaired
  • Enforcing stricter controls on building codes
  • June 2015 - Nepal hosted conference on reconstruction (technical and financial support from other countries)
