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)
Along with the undeniable natural beauty, the Kashmir valley has developed a reputation for adventurous activities like trekking, hiking, and river rafting. Kashmir has maintained its charm, allowing us to time-travel into beautiful destinations which make one forget about the stress and worries of life. The hikes in Kashmir offer adventurers to go on a self-discovery trip through nature's lap over the mountains while taking in the breathtaking scenery that surrounds them on their journey. In addition to the hikes, there are many thrilling adventure activities, like rock climbing, rope climbing, etc. Trekking across the region of mountains and lakes will allow you to experience living in the "Paradise on Earth," and you wouldn't want to return to your regular life after that.
The following are some of the finest hiking destinations in Kashmir:
#1: Kashmir Great Lakes Trek: You will be transported to a heavenly and unseen aspect of Kashmir on the Kashmir Great Lakes Trek. In addition to three high-altitude passes and five river valley crossings, this is the only trip in the Himalayas that includes seven alpine lakes, each of which is a stunning shade of green, blue, or turquoise. The extravagance is limitless and breathtakingly stunning every day: infinite blue sky, a larger-than-life backdrop of the Rocky Mountains, colourful meadows overflowing with wildflowers, river crossings are just a few examples of what you will encounter during the trek.

The Pitru Paksha starts after the Full Moon day, and this day marks the beginning of the waning phase of the Lunar cycle. This event is roughly of 15-day period, and is of great significance. From this day, rituals like Tarpan or Tarpanam and Shradh are carried out to pay respects to dead relatives and ancestors.
It is believed that from the very first day till the last day, the unhappy souls of the deceased return to the Earth to see their family members. So, in order to ensure that the dead attain Moksha, i.e. to get liberation, family members of these souls quench their thirst and satisfy their hunger by performing the Pind Daan, which includes offering food consisting of cooked rice and black sesame seeds. The literal meaning of Pind Daan is the act of satisfying those who no longer exist physically.
For fifteen days, prayers are offered in temples and rituals are performed to help the souls get free from the cycle of birth, life, and death, and attain salvation.
At the same time, the Pitru Paksha is also an important period for people with Pitru Dosha, which means the curse imposed by the ancestors. Hence, in order to ask forgiveness, people perform Shradh rituals and offer food to the crows, who are considered as living beings that represent the dead. It is believed, if the crow eats the offered food, the ancestors are happy and pleased. But, if the crow doesn't eat the offered food and flies away, the ancestors are not happy.
The event of Pitru Paksha is widely observed by Hindus from all over the world, and they perform prayers and rituals in order to gain their ancestors blessings.
At the heart of Bangalore city, a large 300-acre space of lush greenery and heritage stands as a symbol of the city's past, present, and future. Cubbon Park is every child's favourite park, every Bangalorean's haven of fresh air, and altogether, the city's pride.
It stands testament to the past, in terms of the diversity of flora it houses. Bangalore traffic in the recent past has grown into a menace, but the stretch between MG Road and Cubbon Park is always a pleasurable place to stop and wait for the signal to turn green. The gust of wind that blows here, and the smell of mud, coupled with floral scents instantly transports citizens to Old Bangalore, where the weather was fine, and the trees loomed over roads with thick canopies that did not even allow rainwater to penetrate. Cubbon Park is also a historical site, and one of the few remaining monuments of colonial heritage in Central Bangalore. It houses many statues and among them, the most famous is that of Queen Victoria, which faces the St. Mark's Square.

At present, Cubbon Park is known for the cultural hub that it is. It houses Jawahar Bal Bhavan, which is a large theatre that hosts film festivals through the year. Festivals, poetry open mics, and other such shows are conducted on the lawns every Sunday. A small stream runs through the park, where boat rides are held occasionally when the water level is high enough. There is a children's park on one corner, and a government-maintained aquarium, two-storeys tall, with exotic fish.
The Park has been renamed many times in the past. It was originally named Meade's Park, after Sir John Meade, the acting commissioner of Mysore in 1870. It was later changed to Cubbon Park after Sir Mark Cubbon, who was the longest-serving commissioner of the Mysore state. In 1927, the park was renamed after the Mysore Maharaja Sri Krishna Wodeyar, to celebrate his silver jubilee, since the park was developed during the reign of his ancestors. Even though it is officially named Sri Chamrajendra Park, it is still known as Cubbon Park all over the city. In fact, Bangalore was alluded the sobriquet of 'Garden City' because of the rich botanical diversity of this park.

In many parts of the country, governments have renamed structures, places, and cities to remove traces of colonialism. But, in a city like Bangalore, there is too much evidence of the British rule. Many of the most prominent attractions of the city are known by their British identities despite the change in name. Even the city's name continues to be Bangalore, despite having been changed to Bengaluru. Last year, the British era and its achievements were celebrated in Cubbon Park when Sir Mark Cubbon's statue was moved from the grounds of the Karnataka High Court and placed in the Park.
