Great Himalayan Quake: Chamba’s ancient Hindu Temples hold clues, says researchers

Published

Chamba

The team found several telltale signs of earthquake damage, from tilted pillars on the Lakshmi Narayan temples to shifted rooftops on the Bharmour temple.

SHIMLA- Past earthquakes that damaged ancient temples perched high in the Himalayas could be harbingers of dangerous quakes to come, new research suggests.

The supporting pillars and temple structures are tilted with respect to their original positions. The rooftop portion shows tilting or displacement. The bricks of the wall are cracked. The floor stone shows up-warping,

said study co-author Mayank Joshi, a geologist with the Wadia Institute of Himalayan Geology in India.

The area, a picturesque, tourist mountain town in Himachal Pradesh, is sandwiched between two regions where catastrophic earthquakes have killed tens of thousands of people. But researchers didn’t think this area was at high risk until now. The findings suggest that the region is overdue for a major earthquake.

Historical quakes

The area near the Himalayas is laced with terrifying faults. In 2005, a magnitude-7.6 earthquake shook a region of Pakistan called Azad Kashmir, killing 86,000 people and displacing millions. And in 1905, a magnitude-7.8 quake rattled the Kangra Valley in Punjab, India, killing 20,000 people.

But sandwiched between these two regions is the picturesque mountain town of Chamba, and it sustained no damage in these earthquakes. As such, the researchers wanted to know whether the region also faces a large earthquake risk.
Chamba’s Ancient Temples

The team analyzed most ancient structures in the region: intricately carved Hindu temples that were built by rulers of the ancient Chamba Kingdom between the seventh and eleventh centuries. Among the most notable are the stone Lakshmi Narayan temples and the wooden Bharmour Chitrari temples, which were built around the year 680.

Of course, it can be difficult to determine what causes pillars to tilt and floors to deform. But it turns out that the waves rippling out from an earthquake travel in a clear orientation that can make earthquake damage easy to identify, the researchers said.

“In case of the ground settling, there would not be a preferred orientation. It will be randomly oriented,”

Joshi told.

The team found several telltale signs of earthquake damage, from tilted pillars on the Lakshmi Narayan temples to shifted rooftops on the Bharmour temple. The researchers then compared that damage to a temple that was built in 1762, which had no signs of earthquake damage.
Pent up stress

Next, the team pored through the historical record to uncover the history of this Himalayan fault region. The researchers found evidence in the historical accounts of Tarikh-i-Kashmir and the Tabaqat-i-Akbari, which were written Medieval Indian and Kashmiri sultanate writers, that a 1555 quake rattled the Srinagar Valley, about 120 miles (200 kilometers) northwest, and sent aftershocks through the region for days.

This was a destructive earthquake in Kashmir, which ruined towns, killed several hundred people and changed the course of the River Vesha, a tributary of the Jhelum,

the researchers wrote in their paper.

Yet, after this event, there was no major quake in the region, suggesting that the nearby fault could have built up quite a bit of stress in the last several hundred years, the researchers said.

This shows that the area has enough potential to produce great earthquakes similar to [the] 2005 Kashmir earthquake,

Joshi said.

Now that the region’s earthquake risk has been identified, it’s up to engineers to build structures that are safe enough to withstand such an event, Joshi added.

Himachal Gets First Fully Automated ‘Doppler Weather Radar’, Would Provide More Accurate Short Range Forecast

Published

Dopper Weather Radar in Himachal Pradesh's Kufari

Shimla-India Meteorological Department (IMD) January 15, 2021, celebrated its 146th Foundation Day. IMD is one of the oldest, scientific service organizations in the country, in existence well before Independence.

On the occasion, Dr. Harsh Vardhan inaugurated Doppler Weather Radars at Mukteshwar, Uttarakhand and Kufri, Himachal Pradesh; Multi-Mission Meteorological Data Receiving and Processing System in IMD in collaboration with ISRO (MMDRPS).

According to the IMD, these modernized Radars would give a more specific short-range weather forecast.

It’s pertinent to mention that accurate and advance weather information is of utmost importance to Himachal Pradesh – a state largely dependent on agriculture and tourism.

The one installed in Kufari, Shimla, is Indigenous dual polarised X-Band Doppler Weather Radar. Two more Radars would be installed at Mandi and Dalhousie in Chamba district of the State. A site had already been finalized at Mandi and a site for Radar at Dalhousie would be finalized soon, the State Government informed.

This specific type of Radar uses the Doppler effect to gather velocity data. The Radar transmits a signal, which gets reflected when hits a raindrop. Based on the changes in the frequency of the reflected signal, data is obtained about the motion of droplets and intensity of the precipitation. Scientists can analyze this data to determine the structure and severity of storms.

Radar installed at Kufri is on test mode for a period of two weeks. Thereafter its data would be used for forecasting purposes. This Radar has a range upto 100 kilometres in radial distance. It would observe and provide the weather data of 100 kilometres in all directions, which would be used for forecasting purpose, especially for the short-range forecast. More précised area-specific weather forecast and warning can be issued for a particular place, for the weather phenomenon like thunderstorm, lighting, hailstorm, heavy rainfall/snowfall, gusty winds etc.    

This Centre would help the horticulturists and farmers of the State by providing them with accurate weather information.

The DWR Kufri would run round the clock and it is fully automatic. It would transmit the data in various digital format and picture form.

 Forecasting monsoons is the lifeline to India’s food security and affect the economy as the nation’s GDP is dependent on agriculture. Moreover, weather prediction is critical to reducing the loss of lives from various extreme events like a cyclone, heavy rain, thunderstorm, heatwave and cold wave, monsoonal floods and droughts.

India Meteorological Department says that it is modernizing its observational network in the Central and Western Himalayas by the installation of Doppler Weather Radars in a phased manner, at different locations.

IMD said that this radar will be providing severe weather information to the weather forecasters, thus, improving the safety of the public in the states of Uttarakhand and Himachal Pradesh. It will also provide support to the disaster managers and the pilgrims undertaking the pilgrimage to Kailash Manasarovar and Char Dham yatra.

MEE Rank himachal pradesh GHNP

Shimla-The Great Himalayan National Park and Tirthan Wildlife Sanctuary (WLS) have been ranked as the best managed protected areas in India. Sainj WLS has also been placed among the top five Sanctuaries.

Minister for Environment, Forest and Climate Change, Prakash Javadekar, on January 11 released Management Effectiveness Evaluation (MEE) of 146 National Park and Wildlife Sanctuaries in the Country. At present, India has a network of 903 Protected Areas in the country covering about 5% of the total geographic area of the country. The purpose of it was to assess the efficacy of Protected Areas, evaluation of management effectiveness.

The evaluation process was executed by the Wildlife Institute of India, Dehradun, in which  nation-wide 146 National Parks and Wildlife Sanctuaries, including 13 protected areas of Himachal Pradesh, were assessed through a team of evaluators. The score is given for various parameters including staff position, provision of financial resources, degree of protection, peoples’ participation and awareness of the communities towards the conservation values. Against a national average of 62 percent GHNP and Tirthan WLS scored a high of 84.17 percent while Sainj recorded 82.5 percent.

Currently, Himachal Pradesh has a network of 5 National Parks, 28 Wildlife Sanctuaries and 3 Conservation Reserves covering 8391.42 km2 which is 15 percent of the total geographical area of the state.

What is Management Effectiveness Evaluation (MEE)?

Protected area (PA) management effectiveness evaluation (MEE) is defined as the assessment of how well NP&WLS are being managed—primarily, whether they are protecting their values and achieving the goals and objectives agreed upon.

The term ‘management effectiveness’ reflects three main themes of PA management -design issues relating to both individual sites and PA systems, the adequacy and appropriateness of management systems and processes, and delivery of the objectives of NP&WLS, including conservation of values.

 Management Effectiveness Evaluation (MEE) of Protected Areas (PAs) has emerged as a key tool for PA managers and is increasingly being used by governments and international bodies to understand the strengths and weaknesses of the protected area management systems.

MEE is a very important document that provides valuable guidance on various aspects of wildlife and protected area expand MEE of Marine Protected Areas. A new framework for MEE of Marine Protected Areas has been also jointly prepared by WII and MoEF&CC.

In recent years there has been a general concern amongst PA professionals and the public that many NP&WLS are failing to achieve their objectives and, in some cases, are actually losing the values for which they were established (Hockings et al. 2008).

As a result, improving the effectiveness of PA management has become a priority throughout the conservation community. Protected areas that are effectively managed generally lead to improved biodiversity outcomes.

However, only 20% (21,743 NP&WLS) of the total coverage of protected areas reported in the WDPA has been assessed for management effectiveness according to the Global Database on Protected Areas Management Effectiveness (UNEP-WCMC, IUCN and NGS 2018). The result indicated that only 17.5% of the countries have achieved the 60% score of management effectiveness (Coad et al. 2015).

Further, Javadekar also announced that from this year onwards 10 best National Parks, 5 coastal and Marine parks and top five Zoos in the country will be ranked and awarded every year.
