The earthquake on Tuesday morning woke up most of them from their sleep. People filled the streets even in cold weather. Some were carrying children in their arms and some were carrying elderly people and gathered in the streets and alleys.

Attended college morning classes among students. Due to the earthquake, the first year examination of undergraduate level of Tribhuvan University was affected . Because of this, 15 minutes more time has to be added to Tuesday's exam . At 6:50 in the morning, an earthquake of magnitude seven was felt in various districts of Kosi, Madhes and Bagmati provinces of Nepal with its epicenter at Dingi village in Sigatse, Sijang province, China. 

Tuesday's earthquake reminded many of the Gorkha earthquake nine years ago  . At that time, many districts including Kathmandu Valley were affected by the Gorkha earthquake, more than eight thousand people lost their lives and material damage worth billions was caused.

Rikesh Thapa of Kathmandu Nagarjuna-10, who was shocked by the earthquake, jumped from the roof of his house. According to Nepal Police, he was treated at the Manmohan Memorial Institute of Health Sciences, who was injured in the encounter. According to the police, 11 students studying in class 7 and 8 of Trichandra Mavi in ​​Ward No. 1, Devkota, Kalaiya sub-metropolitan city of Bara fainted after the earthquake.

Senior Psychiatrist Dr. Patan Mental Hospital in Lalitpur. Vasudev Karki says that since the effects of the powerful earthquakes of the past are still in their minds, people's confidence has decreased and even when they feel a normal earthquake, they panic more and cannot exercise restraint.

'Many people still have the experience of the Gorkha earthquake in 2072, there is also fear of the Jajarkot earthquake a year ago. These two big earthquakes have weakened the morale of the people,' he said. Mental diseases appear from such calamities. How to manage the stress caused by the disaster? We should take care of that.'

Incidents such as the Karki earthquake do not only cause financial loss, it can have a profound effect on mental health . In particular, people who have experienced an earthquake have more psychological distress, he said. Dr. Karki said, 'Earthquake damage can increase extreme fear and anxiety, it can make them fear whether an earthquake will occur in the future.'

He said that there will be different reactions in different people and the effect will also be different according to the biological environment of the person . "This kind of disaster does not affect everyone in the same way, it can affect some people's mental health a lot, while others don't," he said.

request not to spread unnecessary panic 

Dr. Lokvijay Adhikari, senior seismologist of the National Earthquake Measurement and Research Center under the Department of Mines and Geosciences, has requested not to spread misleading messages that spread unnecessary panic about earthquakes.

'After the earthquake, people run away in panic and jump, which can be an unpleasant event. Earthquake moderation should be adopted,' he said, 'false news like a big earthquake is coming on social media also creates more panic in people, such messages should not be spread by anyone . Earthquake prediction is not possible .' He requested to accept only official information. 

The need for preparedness and awareness 

Center's senior seismologist what to do if there is an earthquake  ? How to adopt moderation? What are the ways to be safe? He said that awareness should be increased and preparations should be made to reduce the loss of property due to earthquakes. He said that priority should be given to early warning system development.

Kamal Ram Joshi, Director General of Water and Meteorology Department, said that earthquake forecasts have not been developed so far and emphasized that more research should be done on this matter. He also mentioned that after the earthquake in China, the risk of glacier break has increased.

'If there is a risk such as avalanches due to earthquakes, we send early warning for the safety of the people . I request you to believe only the official information,' said Joshi.

The spokesperson of National Risk Reduction and Management Authority, Dr Dijan Bhattarai, asked to be in a state of preparedness as the aftershocks of the earthquake are continuing and more aftershocks may occur.

Why do earthquakes happen?

Earthquakes are usually felt when vibrations occur within the Earth's surface. When the earth's surface is disturbed, the tension in the earth's interior increases greatly and the energy released due to that imbalance causes the ground to shake . This vibration causes tremors in the earth's surface and is called an earthquake  . The outer surface of the earth (lithosphere) is divided into different large pieces called seismic plates . These plates collide with each other, which causes earthquakes . 

According to the National Earthquake Measurement and Research Center under the Department of Mines and Geology, an earthquake is a geological process that cannot be prevented or predicted from the current studies. Earthquakes occur due to the friction between tectonic plates. Small earthquakes happen every day, while big earthquakes happen every few years. Small earthquakes that occur every day cannot release the stored energy, so large and destructive earthquakes occur from time to time. 

'There have been big earthquakes in the Himalayan region in the past . Assam in India in 1897, Kangra in India in 1905, Nepal-India border in 1934 and Assam in India in 1950 are the latest intercontinental earthquakes,' said the Center.
