If you were smiling and dreaming in your sweet dream, then your supernatural happiness must have been shattered by the earthquake.
The big shock of the earthquake that came to wake you up with the cock crow!
The quake, which struck at 5:19 a.m. Wednesday, had the power to wake up many. Some even left the house. By the time they got out, the tremors had stopped.
According to the National Earthquake Measurement and Research Center, the epicenter of the 6-magnitude quake was Ramche in Sindhupalchowk. This is called the continuation of the Gorkha earthquake of 2072.
Although small in terms of loss of life and property, 6 magnitude is not trivial. This is the biggest push since 29 April 2072.
You should remember that after the 7.6 magnitude earthquake centered on Gorkha on 12 April of that year, there were two big aftershocks of 6.8 and 6.2 on the same day on 29 April. The center of both was Dolakha. This caused a lot of damage in Dolakha and Sindhupalchowk.
In the five years since then, Sindhupalchowk and Dolakha have been the epicenter of more than 5 magnitude tremors. However, the 6 magnitude was not yet.
“It had been a long time since there had been such a big earthquake,” Lok Vijay Adhikari, a geologist at the center, told Sethopati.
Such tremors can be dangerous for Sindhupalchowk. Landslides have been going on there since the onset of monsoon. Landslides are exacerbated by earthquakes.
Chief Executive of the Disaster Risk Reduction and Management Authority Anil Pokharel had questioned the police administration and local government chiefs of Sindhupalchowk since Wednesday morning. He says no damage has been reported so far.
“I am in touch with the police-administration and the people’s representatives there,” he said.
According to geologists, the 2072 earthquake started from Gorkha and reached Dolakha. Since then, the territory has not been stable. The epicenter was reported below the ground, however; no tsunami alert was issued. The epicenter was reported below the ground, however; no tsunami alert was issued.
The terrain of Kathmandu, Sindhupalchowk and Dolakha seems to be the most active in terms of earthquakes. For this, let’s look at the one-year statistics of the Earthquake Measurement Center.
There have been three earthquakes in Sindhupalchowk and four in Dolakha district in the last one year. They were all between 4 and 5.3 magnitude. It had been almost nine months since the epicenter of the Sindhupalchowk earthquake. The last time there was a 4.8 magnitude earthquake was on 26 December 2076.
During this period, the territory of Kathmandu Valley seems to be more active.
There are records of eight earthquakes centering on different places in the valley. Of these, the shock of 2077 BS was the biggest. At 6:29 a.m., a 5.2 magnitude shock was felt. At 6:40 a.m., a magnitude 4.3 earthquake shook the region. In addition, other vibrations are less than 4 magnitude.
What is the reason that the earthquake wave from Gorkha has been shaking the area from Kathmandu to Dolakha for more than five years?
We had a long talk with the geological officer of the center about this.
Below the earth’s surface, there are many large chunks of rock. When these rocks collide with each other, earthquakes, volcanoes, and tsunamis occur. Below the surface on which we stand in Nepal, two great rocks have been fighting each other for millions of years. It is called the Indian and Eurasian plate.
The friction of these two plates or rocks has formed mountain ranges and mountains. We are still forced to withstand the effects of the same friction.
When the Indian and Eurasian plates began to collide millions of years ago, the fissures formed by them were not uniform from east to west. That is why whenever a new earthquake hits this region, the cracks it creates are not uniform. It is scattered up and down and sometimes it gets stuck somewhere.
According to the official, the cracks in the Gorkha earthquake were not uniform from east to west. This crack reached Dolakha via Kathmandu, but could not proceed from there. He said that the earthquake wave was more concentrated from Kathmandu to Dolakha.
Let’s take the example of borrowing clothes to make it easier to understand.
You may have seen a piece of cloth torn. At the beginning, it is slightly torn, but after the road is paved, it starts to rise. If we consider the power of clothes to rise as an earthquake wave, then that power did not go beyond Dolakha. That is, the place of the cloth was not completely torn.
‘If the 2072 earthquake had reached the base of the Chure and cracked the ground, its power would have been lost at that time. However, it got stuck in the southern part of Dolakha and Kathmandu, ‘he said.
However, the Dolakha earthquake of April 29 had occurred at a depth of more than 20 km. On top of that there were already many other small cracks.
It has become like a network of seismic cracks beneath the surface of Dolakha and Sindhupalchowk, the official said, adding that ‘seismic power continues to be transmitted there. The same force pushes each other to find a place to live by ‘adjusting’ each other.
He further said, “Many earthquakes have hit the region due to the process of power adjustment.”
Apart from this, another major reason is the strength of the earthquake which is stuck 11 km below the southern surface of Kathmandu.
The Department of Mines and Geology has released data from GPS stations in different parts of Nepal immediately after the Gorkha earthquake.
