Answer:
A
Explanation:
The origin of the earthquakes is the same tectonic, plate-moving action that welded the Indian subcontinent to Eurasia and formed the Himalayan Mountain Range as a kind of massive suture. Along the line where the outer Himalayas border the Gangetic Plain, seismic gaps store the strain from tectonic movement. One of these, called the Central Seismic Gap, has not released its strain in the form of an earthquake in an estimated 745 years (since a great quake appeared to have killed the king of Nepal in 1255). The Central Seismic Gap is about 500 mi (800 km) long and lies between the regions struck by great earthquakes in 1905 and 1934.
