In geological terms, the tremor occurred like clockwork, 81 years after the region’s last earthquake of such a magnitude, in 1934. Records dating to 1255 indicate the region known as the Indus-Yarlung suture zone experiences a magnitude-8 earthquake approximately every 75 years, according to a report by Nepal’s National Society for Earthquake Technology.The reason is the regular movement of the fault line that runs along Nepal’s southern border, where the Indian subcontinent collided with the Eurasia plate 40 million to 50 million years ago.
Challenges faced by the rescue team.
European, Asian and North American governments sent emergency response teams to Nepal as the country struggles to cope with the disaster. However, blocked roads, collapsed buildings, and continuing aftershocks pose major setbacks for emergency crews searching for survivors in the capital and cut-off rural areas.
Measures taken if caught in an Earthquake of large Magnitude.
1)Find out what to do before, during, and after an earthquake.
2)Make a family emergency plan, so that everyone knows what to do, and where to go in case of an emergency.
3)Get an emergency kit, so that you and your family can be self-sufficient for at least 72 hours.
