The Indian Ocean Experiment (INDOEX) was sponsored by research agencies within Europe, India and USA, and was mainly concerned with the haze over south Asia and the adjacent Indian Ocean. It excluded other equally or even more polluted areas in Asia. The Asian Brown Cloud is a follow on international research project that includes all of Asia.
The Himalayan arc, 40% of which ruptured in the last two centuries, has witnessed half a dozen large to great earthquakes including the 1833 and 1934 Bihar
The Deccan Trap geology of Bombay (Mumbai) differs from the main Deccan flood basalt province in several ways. Very few geological, geochemical and geochronological studies exist on the Deccan geology of Bombay. The basalt of Gilbert Hill, Andheri occupies a special place in Bombay geology on account of its spectacular columnar jointing, more than 50 m high, and for this has been designated a National Geological Monument by the Geological Survey of India.
About 80 tropical cyclones (with wind speeds equal to or greater than 35 knots) form in the world’s waters every year. Of these about 6.5% develop in the Bay of Bengal and Arabian Sea. Since the frequency of cyclones in the Bay of Bengal is about 5 to 6 times the frequency of those in the Arabian Sea, the Bay of Bengal's share comes out to be about 5.5%. The tropical cyclones forming in the Bay of Bengal hit the coast of India (particularly the states of Andhra Pradesh, Orissa and West Bengal) every year, causing heavy loss of life and property.
Latitudinal distribution of radiative flux at different layers has been measured for the first time over the Indian Ocean from 15°N to 20°S during intensive field
phase of INDOEX 1999. Simultaneously measurements have been made over three Indian ground stations, viz. Delhi, Pune and Trivandrum. The basic feature of
radiative flux over the Indian Ocean, Delhi, Pune and Trivandrum is similar, i.e. the radiative flux increases with altitude and reaches a maximum value at 15 km
A developing country like India, with a variety of building practices and social and economic structure, needs to evolve its own strategies for seismic hazard evaluation. Occurrence of few damaging earthquakes during the last decade has pointed to our shortcoming in risk reduction programmes.
India is facing a serious double burden of disease. Most of the old infectious diseases like malaria, filariasis and kala-azar have not yet disappeared; indeed they are bouncing back. At the same time, other chronic non-communicable diseases such as cancer, cardiovascular disease and respiratory disorders are becoming more dominant.
The fossilized skull of Narmada Homo erectus was found embedded in a conglomerate bed in the Narmada valley of central India. This bed occurs at the basal part of a formation sandwiched between two other formations of 0.73 Ma and 74000 yrs BP. The conglomerate bed has also preserved fossils of Hipopotamus namadicus, etc having Middle Pleistocene affinity.
In Bangladesh, arsenic in groundwater above 0.05 mg/1, the maximum permissible limit laid down by WHO, was found in 41 out of 64 districts. People suffering from arsenicosis have been identified in 20 districts out of 21 districts we have surveyed so far.
