Drop, Cover and Hold (DCH) disaster in Nepal Earthquake 2015

Almost everybody in the developed world suggests that ‘Drop Cover Hold’ (or Duck, Cover and Hold) is the best policy during an earthquake. A lot of NGOs and INGOs had suggested the techniques and taught it to the Nepali school children. The April 25 earthquake showed that the ‘Drop Cover Hold’ notion was wrong in Nepali contest, in a very disastrous way. A lot of corpses positioned in ‘Drop Cover Hold’ were found in the rubble after the earthquake. Many believe, a lot of those who died might have survived if they had run out instead of taking cover in the crumbling buildings.

What is Drop, Cover and Hold ?

In the event of an earthquake, people are instructed to ‘Drop’ down so that they don’t fall and take ‘Cover’ under something strong. People are asked to get under sturdy bed, desk or table to avoid falling objects. They are instructed to ‘Hold’ on something to keep themselves steady until the earthquake shaking stops. The person can get out to the open space after the shaking stops.

This method holds good if the building is constructed to deal with earthquake. Most of the structures in earthquake prone zones in the world are made earthquake resistant and they can hold on for a while, until the people escape after earthquake before falling down. That is why the method is widely publicized. Following are some of the official documents of different countries.
