The state of Bihar has been facing floods since for a long time. By Dr. Nitish Priyadarshi Bihar is India's most flood-prone State, with 76% of the population in the north Bihar living under the recurring threat of flood devastation. According to some historical data, 16.5% of the total flood affected area in India is located in Bihar while 22.1% of the flood affected population in India lives in Bihar. About 68,800 square kilometres (26,600 sq mi) out of total geographical area of 94,160 square kilometres (36,360 sq mi) comprising 73.06% is flood affected. Geographically Nepal is a mountainous region. When heavy rains occur in the mountains of central and eastern Nepal the water flows into the major drainages of Narayani, Bagmati, and Koshi rivers. As these rivers cross into India they flow into the plains and lowlands of Bihar and break their banks. Bihar is surrounded by Nepal in the north, West Bengal in the east, Uttar Pradesh in the west and  Jharkhand t...

10 quakes in 18 years in J'khand, claims geologist Jharkhand has experienced more than 10 tremors in 18 years though their intensity was mild to medium, geologist Nitish Priyadarshi claimed and suggested that newly constructed buildings in the state should be earthquake-resistant. 'Back-to-back tremors occurred for the first time in Jharkhand. The state has never experienced aftershocks,"Priyadarshi, a member of the Geological Society of India, said here.     He said the Chhotanagpur Plateau in Jharkhand represents a part of the Indian Peninsular field that is "stable cratonic block of the earth crust".     Craton is the stable interior portion of a continent characteristically composed of ancient crystalline basement rock and there is a belief that land above a cratonic block is generally shielded from earthquakes.     "The cause for concern is that there had been more than 10 mild to medium tremors occurred in the area since 1997," sai...

"Major tremor expected anytime, not possible to predict exact time," says geologist , AniNews.in Ranchi, Apr. 27 ( ANI ): Geologist Nitish Priyadarshi has stated that another major tremor can be expected anytime and the countries near the Himalayan region should be on high alert. "Major tremor can occur anytime, maybe in a week or two.It is not possible to predict the exact time. Countries near the Himalayan region like Afghanistan, Nepal, India and Pakistan should be on high alert," Nitish Priyadarshi told ANI here. Priyadarshi asserted that the earthquake was triggered by natural phenomenon and anthropogenic activities as well. "The main reason for this earthquake is tectonic movements, the plates are colliding with each other, below the Himalayas. Also, the huge blasting which is going on in Himalayas to make roads is impacting the rocks in the Himalayas. This earthquake is trigged by natural phenomenon and anthropogenic activities as well,"...

They are Orchid, Zingiber purpureum and Asparagus racemosus. By Dr. Nitish Priyadarshi Geologist. Email: nitish.priyadarshi@gmail.com Hill near Bundu on Ranchi-Jamshedpur road. Introduction: Medicinal plants have been identified and used throughout human history. Plants have the ability to synthesize a wide variety of chemical compounds that are used to perform important biological functions, and to defend against attack from predators such as insects, fungi and herbivorous mammals. At least 12,000 such compounds have been isolated so far; a number estimated to be less than 10% of the total. The use of herbs to treat disease is almost universal among non-industrialized societies, and is often more affordable than purchasing expensive modern pharmaceuticals. The World Health Organization (WHO) estimates that 80 percent of the population of some Asian and African countries presently use herbal medicine for some aspect of primary health care. A large amount of archaeological eviden...

Heavy rainfalls battered the western Himalayas last week due to a clash between monsoon currents and winds from the Caspian Sea.  by Dr. Nitish Priyadarshi Geologist Ranchi.

Inadequate surface drainage and encroachment in the floodplains has caused the floods of Kashmir. By Dr. Nitish Priyadarshi Geologist Ranchi . Heavy rainfalls battered the western Himalayas last week due to a clash between monsoon currents and winds from the Caspian Sea. The Srinagar weather station – in the summer capital of the Indian state of Jammu and Kashmir – recorded 250 mm of rain between September 3-6. For hundreds of million years Kashmir Valley is supposed to have remained under Tethys Sea and the high sedimentary-rock hills seen in the valley now were once under water. Geologists have come to believe that Kashmir Valley was earlier affected by earthquakes. Once there was such a devastating earthquake that it broke open the mountain wall at Baramulla and the water of the Satisar lake flowed out leaving behind latchstring mud on the margins of the mountains known as karewas. Thus came into existence the oval but irregular Valley of Kashmir. In September 2014, the ...

The hills of Ranchi are generally small isolated residual hills.  By Dr. Nitish Priyadarshi.  Fig.1. A small hill in Pithoria. The hills of Ranchi are generally small isolated residual hills. In Ranchi hills are generally steepsided made of massive granite-gneiss. We have also found the hills which are not steepsided but a mere irregular pile of huge boulders were found on the hills especially in Pithoria area of Ranchi district. This is the result of highly jointed elements of granite gneiss. According to climatic geomorphologist like Tricart qualify such hills as inselbergs. They are steepsided residual hills made of massive granite-gneiss. But close by within a few kilometers or a few hundred meters we have residuals which are not steepsided inselbergs but a mere irregular pile of huge boulders. The rocks disintegrate along these joints under the hydrothermal and atmospheric effects thus leading to the formation of tors or rounded shapes of these ancient granite rocks a...
