A second major earthquake occurred in Nepal on 12 May 2015 at 12:35 pm with a moment magnitude of 7.3, 18 km (11 mi) southeast of Kodari. The epicenter was in the border of Dolakhaand Sindhupalchowk, the two districts of Nepal. This earthquake occurred on the same fault as the larger magnitude 7.8 earthquake of 25 April, but further east than the original quake. As such, it is considered to be an aftershock of the 25 April quake. It struck at a depth of 18.5 kilometres (11.5 mi). Tremors were felt as far as about 2400 kilometers away from the epicenter in Chennai.

Minutes later, another 6.3 magnitude earthquake hit Nepal with its epicenter in Ramechhap east of Kathmandu. The earthquake was felt in Bangladesh, China and many other states in India. The impact of these tremors was felt even 1,000 kilometres away in the Indian capital New Delhi, where buildings shook and office workers evacuated.

The aftershock caused mass panic as many people were living in the open air after the 25 April quake.  Even when the shaking stopped, people were still screaming. The tremor caused fresh landslides, and destroyed some buildings which survived the first quake.

Impact
Tremors were felt in the Indian states of Bihar, Uttar Pradesh, Assam, West Bengal, Sikkim, Uttarakhand, Odisha, Andhra Pradesh, Gujarat, New Delhi and as far south as Karnataka.The earthquake was also experienced across southwestern China, ranging from the Tibet Autonomous Region to Chengdu, which is 1,900 km away from the epicentre. Tremors were also felt in Pakistan and Bhutan.

Aftermath
The Unicef has said that close to a 1 million children have been “severely affected” by the disaster. The UN says the quake has affected 8.1 million people – more than a fourth of Nepal’s population of 27.8 million – and that 1.4 million needed food assistance.Nepal is still reeling from the magnitude 7.8 earthquake on April 25 that devastated large areas of the Himalayan nation and killed more than 8,000 people.
