Updated data by US Geological Survey have raised the magnitude of the morning earthquake in Nepal to 7.9. The massive earthquake has toppled houses’ walls and destroyed ancient temples.
The epicenter of the quake was in Pokhra. According to Indian Metriological Department, the epicenter was at Lat. 28.1°N , Long. 84.8°E, although its aftershocks were felt in Delhi-NCR, Kolkata, Jaipur, Lucknow, Ahmedabad.
Pictures showing severed buildings have started appearing from Nepal. Dharahara Tower, also known as Bhimsen Tower, in Kathmandu, a nine story structure has also collapsed.
As of now, no estimate on the number of deaths has come out; however, a news agency has reported that about 100 people have died due to the quake.
Nepal’s Information Minister Minendra Rija said, “We need support from the various international agencies which are more knowledgeable and equipped to handle the kind of emergency we face now.”
Meanwhile, India’s Prime Minister, Narendra Modi, has convened a high level meeting with ministers and top officials at 3 PM. He is also trying to contact Nepal PM, Shri Sushil Koirala, who is not in the country right now.
Expressing concern over the issue, Prime Minister Narendra Modi tweeted, ‘We are in the process of finding more information and are working to reach out to those affected, both at home & in Nepal.’
Mountaineer Daniel Mazur has also tweeted, “A massive earthquake just hit Everest. Basecamp has been severely damaged. Our team is caught in camp 1. Please pray for everyone.”
It is said to be the worst earthquake to hit Nepal in 80 years. In 1934, Kathmandu was devastated by an enormous earthquake.
Bengaluru, October 16, 2017 : Continuous monitoring of water levels in the foothills of the Himalayas can warn about an impending earthquake in the region, which is due for a major temblor.
This recommendation to the Ministry of Earth Sciences has come from Ramesh Singh, professor of environmental sciences at California’s Chapman University, who is also president of the Natural Hazards Group of the American Geological Union.
Singh says the utility of monitoring the water levels of underground aquifers for predicting earthquakes in quake-prone regions has been confirmed from analysis of water level data in a bore hole collected during the earthquake that rocked Nepal’s Gorkha district on April 25, 2015.
The findings of the study carried out by Singh and three seismologists from China have recently been published in the journal Techtonophysics.
The Gorkha quake, one of the deadliest in Nepal, killed about 5,000 people mainly in Nepal, a few in bordering India, two in Bangladesh and one in China, and injured about 9,200 people.
Whenever earthquakes occur, widespread cracks and deformations on the earth’s surface are common, resulting in changes in groundwater levels, Singh told this correspondent in an email.
In China, many parameters are being monitored in water wells, including water level, water temperature, and water radon concentrations to detect any signal prior to an impending earthquake.
According to the scientists, due to seismic wave propagation, the volume of an aquifer expands and contracts, forming fractures that change the water flow in a bore well sunk into the aquifer.
In the case of the Gorkha quake, the scientists considered the water level in a bore well — called “Jingle” well — atop an aquifer in China’s Shanxi province, 2,769 kilometres from the temblor’s epicenter. The data was analysed soon after the Nepal earthquake.
A “spectrum analysis” of the co-seismic response of the bore hole water level showed large amplitude oscillations with a maximum peak-to-peak value of about 1.75 metres associated with ground vibrations generated by the earthquake, says their report.
In addition, the analysis revealed the arrival of a possible precursor wave at the “Jingle” well about 6.5 hours prior to the actual occurrence.
“The study of co-seismic changes in groundwater has emerged as an important research area which can provide an improved understanding of earthquake processes and corresponding changes in surface and subsurface parameters,” Singh said.
Water level data in close proximity to the epicenter may be of great importance in getting early warning signals of an impending earthquake, he said. China and the United States routinely monitor aquifer water levels at 15-minute intervals.
In the light of the finding, Singh said that “India’s Ministry of Earth Sciences may consider deploying water level sensors in the Himalayan foothills areas, which may provide valuable information about an impending earthquake in the Himalayan region, which is due for a major earthquake.”
Such data, he added, “is also useful in understanding the dynamic nature of the Indian plate”.
However Arun Bapat, former head of Earthquake Engineering Research at the Central Water and Power Research Station in Pune, says he has some reservations about the study’s conclusion that water level changes observed in the bore hole were the warning signal for the Gorkha earthquake.
“Various effects associated with a large earthquake (Magnitude 7.5 or more) such as electrical, magnetic, geological, tectonic, hydraulic, radioactivity, etc., have been observed within about 600 to 800 km from the epicenter (but not beyond),” Bapat told IANS.
Bapat said the magnitude of the Gorkha quake was about 6.5 to 6.75 which is considered as moderate. “The effect of this quake on water level changes at a distance of 2,769 kilometres from its epicenter is almost not possible.” (IANS)
Mexico, September 20, 2017 : A powerful earthquake of 7.1 magnitude struck Mexico city, leaving more than 200 people dead and many trapped under the collapsed buildings. At about 2.15 p.m. (local time) on Tuesday, the earthquake shook central Mexico, its epicenter was 4.5 km east-northeast of San Juan Raboso and 55 km south-southwest of the city of Puebla, in Puebla state.
“We are facing a new national emergency,” said Peña Nieto, President of Mexico, in his first televised address following the earthquake.
The earthquake was felt far and wide. In Mexico City, there were power outages and more than 40 buildings collapsed crushing cars and trapping people inside.
Dozens of buildings collapsed or were severely damaged in densely populated parts of nearby states also.
Thousands of soldiers, rescuers and civilians — including college students — in Mexico City clawed through the rubble with picks, shovels and their bare hands. Windows buckled and shattered, falling several stories to the ground while thousands of people streamed into the streets running away from buildings and potential gas leaks.
People struggled to get home when power poles that toppled in the quake blocked the streets and the public transportation system temporarily shut down operations. Nearly 5 million customers were still without power early Wednesday.
The earthquake came less than two weeks after a massive 8.1-magnitude quake hit the country on September 7 and killed nearly 100.
The earthquake took place on the anniversary of a devastating earthquake that killed thousands in Mexico City in 1985. Just hours before the quake hit, many people took part in drills and commemorative events.
All public and private schools in Mexico City and some of the states affected by the earthquake will remain closed until further notice, Education Minister Aurelio Nuño tweeted.
Foreign leaders sent messages of support to Mexico. US President Donald Trump, who has courted controversy with his plans for a border wall with Mexico, tweeted: “God bless the people of Mexico City. We are with you and will be there for you.”
Canadian Prime Minister Justin Trudeau also tweeted his support following the “devastating news”.
Changu Narayan is considered to be the oldest temple in Nepal
It is based on a high hilltop know was Changu or Dolagiri
It is dedicated to Lord Vishnu and has an interesting tale behind it
New Delhi, July 14, 2017: The ancient Hindu temple Changu Narayan is situated on the top of a high hill well known as Changu or Dolagiri. The temple had a neighboring forest of champak tree and a small village called Changu and is situated in Bhaktapur District, Nepal.
The hill is about 7 miles or 12 km east of Kathmandu and a few miles north of Bhaktapur. This holy place “changu narayan Temple” is devoted to Lord Vishnu and held in admiration by the people of Hindu religion. Changu Narayan is believed to be the oldest temple in Nepal’s history. Bhaktapur king established kingdoms in Kashmir and kept it as Hindu kingdom.
“changu narayan Temple” has a very intriguing story behind its existence. In old times, a Gwala, a cow herder, was given a cow by a Brahmin whose name was Sudarshan. The cow was believed to produce milk in large quantities. The cow herder used to take the cow for grazing to Change, which was a Champak trees forest that time. The cow was always found under a particular tree’s shade while grazing. In the evening, when the Gwala started milking the cow at his house, he received only a negligible quantity of milk. This continued for a number of days. He was disappointed and told the Brahmin about the cow not giving enough quantity of milk. After seeing this incident with his eyes, Sudarshan agreed and they decided that they should examine the cow while her grazing activity was being undertaken.
Both of them hid behind the trees and observed the cow. They noticed that a small black boy who had come out of the tree started feeding himself with the milk. This infuriated the two men as they thought of the boy as a demon and the tree as its home.
So the champak tree was cut down by the Brahmin. While he was doing this, he saw human blood come out of the champak tree. Both Brahmin and Gwala presumed they had done a crime and started crying.
Lord Vishnu suddenly emerged and told the Gwala and Brahmin, the mistake was not theirs and began narrating the story of him committing a crime by unknowingly murdering Sudarshan’s father while forest hunting. Afterward, he was cursed and he wandered on his mouth, as ‘Garuda’ descending on the Changu hill where he survived on stolen milk. The cutting down of the tree by Brahmin beheaded Vishnu and freed him from his sins.
Following this incident, Brahmin and Gwala started worshiping that place and built a small temple of Lord Vishnu. That place has been considered sacred ever since. Even today, Sudarshan’s descendant is one of the priest of that temple and the Gwala’s descendants as conservators.
People belonging to Newar community reside in and around the area of Changu Narayan. Due to tourism development in this area, we can locate many hotels, souvenir shops, restaurants etc.
However, this holy temple “changu narayan” faces a lot of challenges and threats. The Manohara stream has witnessed rampant mining of sand and stones. The local administration has failed to cut down the mining activities. Due to these mining activities, the temple area has become prone to landslides. Because of overgrazing in the nearby forest, the chances of soil erosion and landslide have become very high.
