AKIPRESS.COM - An earthquake, 7.4 in magnitude and only 19km deep, has hit 68km west of Namche Bazaar, Nepal, according to US Geological Survey.

It comes just a few weeks after a devastating 7.8-magnitude quake left over 8,000 people killed, and almost 18,000 injured.

Around 8 million people in Nepal, which has a total population of 28 million, have been affected by the disaster, the UN estimated.

Some 2 million people still need tents, drinking water, food and medicine.

The latest tremor struck near the base camp for Everest, and was felt across the country, including the capital, Kathmandu. Everest Base Camp was evacuated after an avalanche caused by the last quake killed 18 climbers. Mountaineers subsequently canceled this year's Everest season.
