Vedic literature includes the Vedas,

Upanishads, Brahmans, Aranyakas,

Puranas, epics and Shilpasamhitas etc. It is now proved that these are encyclopedias full of scientific and technical information.

India was called as Jambudweep (Iceland ,shape of which is like a guava) . India has gigantic rivers such as Sindhu,

Ganga and Bramhaputra in the northern part and Arabian Sea, Bay of Bengal and Indian Ocean on other sides. The ancient names for Arabia and Mesopotamia were Shalmali Dweep and Shak Dweep respectively.

Ancient Indian sages have described “Bharatavarsh or Bharatakhand” as the land between Himalaya and Kanyakumari. The land of India was formed in three different periods and under different geological conditions.

Description of Ancient India

हि�माद्रि�कन्योरंतर्ग�तो देशस्तु भारत: ॥ सोऽहि� देशस्त्रिस्�धाभिभन्नस्तत्तदेशभवैरु्गर्णै$: ॥हि�रु्गरं्णै तस्त्रि%�चकं्र च हि�वर्णै(च क्रमातस्मृतं ॥ शि+ल्�र%न अ १६

Ancient text “Shilparatna” describes these three rock formations as shown in Map 1.

The entire time span was divided into four Yugas namely Tretayuga, Krutayuga, Dwaparyuga and Kaliyuga. Modern geologists call these as Primary, Secondary, Tertiary and Recent respectively.

This land can be classified into three types according to the three time spans, three stages or three colors. Due the different conditions of formation, the rocks, minerals, climate, flora and fauna are also of three types.

1. Land between Himalaya and Vindhya mountains is formed by sedimentation of soil particles.

2. Land between Vindhya Mountain and Tungabhandra River is formed of igneous rocks as a result of cooling of molten magma.

3. Land to the south of Tungabhandra River is formed of metamorphic rocks.

Ancient texts designate these three land zones as Saatwik, Raajas and Taamas The texts describe these zones as below.

आग्नेयाविवंध्यसह्याद्या: सौम्यो हि�महिर्गरेस्तत: ।अतस्तदोषधाहिन स्यु: अनुरू�ाभिर्णै �ेतुभिभ: ॥ भृरु्गसंहि�ता हि�मवव्दि>दंध्ययोम�ध्यं सात्वि%वकं भूतलं स्मृतं ॥विवंध्यशैलाद्रिदकृष्र्णैांतं रजस �रिरकीर्तिततंं ।�ुन: कृष्र्णैाद्रिदकन्यांतं तामसं भूतलं भवेद॥्नार्गरं सात्वि%वके देशे , रजसे �ाहिवडं भवेद।्वेसरं तामसे देशे, क्रमेर्णै �रिरकीर्तिततंा: ॥ शिशल्�र%न अ १६

A-Saatwik land: The hilly area between Himalaya and Sahyadri mountains comprises of igneous rocks. The climate in this area is hot or cold and fruits are dry or juicy. The rocks do contain fossils. This land is suitable for Nagar style of planning and Kashyapa type architecture,

B-Rajas Land: The area between Vindhya mountain to Krishna river is termed as “Rajas” or “Raja sampanna” (which means made of fire and ash). This land is suitable for Nagar style of planning and Bhrugu type architecture.

C-Tamas land: The land below Krishna River is termed as “Tamas” (a Shadow forming land).

This land is suitable for Nagar style of planning and Maya type architecture.

Ancient Indian lexicon “Bruhan Nighantoo” also mentions the characteristics of these zones . Aagneya Zone:The ground is plane, with little vegetation, Terrain is Hilly with boulders,Common trees are Shmee, Karir, Bel ,Pilu, Ber etc,Common animals are Deers, Bears, Tigers, and Bison etc.Fruits are sweet and juicy, Land is full of forests, Windy area.It is full of oasis, dusty, dry lakes, Irrigation mainly depends on well water, There is scarcity of grass hence scarcity of milk. Rice as main crop, People with angry mood etc.

Soumya region: Land is full of rivers, lakes, hills, Lakes are full of lotus plants,Common birds are swans, Saras, Karandav,Chakrawak etc, Common animals are rabbits, pigs, buffalo etc.Trees are green and full of leaves, flowers and fruits ,Common crops are rice and sugarcane. Rivers are with abundant water,People suffer from cough or acidity,Such land is a reclaimed marshy land.

Taamas or SadhaaraN land:This land is of mixed properties, The soil is neither too wet nor too dry and non Silty soil, Trees are without thorns trees, There is adequate ground water, Climate is neither to hot nor cold, Main crops are wheat, black gram, Bengal gram and maize. The land is plain and comfortable. Physicians term it as average land.

Comparison of ancient and modern geography

A-Kruta Yug is the period in which large geological transformations took place. The southern part of India was formed in this period. It never went under water.B- Treta Yug was the period in which mountains and hills were formed due volcanic eruptions. Land of Maharashtra and Vindhya region was developed in this period. C-Dwapar Yug was the periods in which sedimentary rocks were formed. River basins of Sindhu, Ganges and Yamuna were formed in this period.D- Kali Yug is the present period in which no major geological activities are occurring.

The growth of vegetation and animals depends

upon the land and the climate thereof. The

customs of people also depend upon local

conditions. The construction practices too depend

upon available building materials of the land.

Eighteen styles of architecture were evolved

based on eighteen regions of ancient India.

A Sanskrit text BruhaNighantu (Worlds first lexicon) describes the animals, trees and minerals found in these three lands.Subsequently the thee lands were divided into five lands as belowThirty-one major rivers of south Asia are mentioned in Nadi-

stuti (praise of rivers) of Rig Veda. The epic Mahabharata contains a separate chapter devoted to geography of Indian subcontinent and adjacent countries in central IndiaPurana means old. One finds mention about Nile River in Skanda Purana. Puranas which are historical accounts of traditions, personalities, and their achievements, evolution of crafts, cosmology, cosmogony, cosmography, regions and people living therein.

Geology: Arthshastra is the earliest Indian text dealing with the mineralogical characteristics of metallic ores and other mineral-aggregate rocks. It recognizes ores in the earth, in rocks, or in liquid form, with excessive color, heaviness and often-strong smell and taste. The Arthshastra also mentions several subsidiary types of gems named after their color, luster or place of origin i.e. Vimalaka,

jyotirasaka, lohitaksa, sasyaka etc. It is surprising that even in the I Millennium BC; Indians had developed an elaborate terminology for different metals, minerals and alloys.

Geology

Many ancient Indian texts contain references related to earthquakes. Most of the references contain myths about the phenomenon of earthquake. But Brihat Samhita of Varaha Mihira (5–6th century AD) and Adbhuta Sagara of Ballala Sena (10–11th century AD) are the only texts which contain some technical information on earthquakes.

Earthquakes

Some myths about earthquakes are listed below.1. Kashyapa: The earth floats over a big ocean. It moves or shakes due to the movements of big aquatic creatures.  2. Garga: There are four "Quarter-elephants (Dig-gajas) supporting the earth on four sides.  When they get exhausted, they heaive a heavy sigh of relief. Hence the earthquakes and strong devastating winds blow over the earth.   3. Vasistha: When two powerful atmospheric currents collide and dash against the earth, there is earthquake.  4. Vrddha Garga: The earthquakes are due to some unseen (adrusta) cause.   5. Parashar: Earthquakes are caused by the solar and lunar eclipses and by the unnatural changes in plants.

Myths about earthquakes:

Bhishnaparwa of epic Mahabharata contains information on Animal behavior which may be precursors of earthquakes.

Hawks and vultures, and crows and herons, together with cranes, are alighting on the tops of trees and gathering in flocks. These birds, delighted at the prospect of battle, are looking down (on the field) before them. Carnivorous beasts will feed on the flesh of elephants and steeds. Fierce herons, foreboding terror, and uttering merciless cries, are wheeling across the centre towards the southern region

Precursors of earthquakes:

Kokilas, wood-peckers, water-cocks, parrots, crows and peacocks utter terrible cries.At sun-rise flights of insects by hundreds are

seen.

The animals are all weeping and their tears are falling fast.

The 32nd chapter of Brihat Samhita is devoted to signs of earthquakes and correlates earthquakes with cosmic and planetary influences, underground water and undersea activities, unusual cloud formations, and the abnormal behavior of animals. Varahmihir analyzed and arranged the details about the earthquakes on the following points:  •Time of the day. (Muhurta)•Presiding deity of that period (Devta)•The asterism assigned to the deity (Nakshyatra)•Prognostic symptoms of the quake (Yuti of

planets)

Ancient: Varahmihir categorizes earthquakes into different kinds and says that the indications of one particular kind will appear in the form of unusual cloud formations a week before its occurrence. Following are the, indications appearing a week. "Huge clouds resembling blue lily, bees and collyrium in color, rumbling pleasantly, and shining with flashes of lightning, will pour down slender lines of water resembling sharp clouds. An earthquake of this circle will kill those that are dependent on the seas and rivers; and it will lead to excessive rains."

Earthquake prediction using earthquake clouds:

Over the last ten years, Zhonghao Shou, a retired chemist based near Caltech in California, has been using satellite imagery and other scientific tools to fine-tune his theory of "earthquake clouds" as precursors to earthquakes. According to Shou, earthquake clouds are formed when underground water is converted into water vapors by the heat generated in the epicenter area of a fault rock, which is undergoing constant stress and friction.Zhou says that earthquake prediction is possible by identifying such clouds as "an earthquake generally occurs within 49 days of the first appearance of the cloud. Details of Zhous work are available on web.
