Unravelling a quake mystery

The mystery that has been shrouding the genesis of the reservoir-induced earthquakes in Koyna region in Maharashtra is likely to be unravelled soon. An assurance to this effect has come from Dr. Harsh K. Gupta, Director of Hyderabad based National Geophysical Research Institute (NGRI). The development assumes importance as Koyna, …

Meet on earthquakes from Jan 25

A five day Chapman conference (American Geophysical Union) on stable continental region earthquakes will be held on the premises of National Geophysical research institute (NGRI) in Hyderabad from Jan 25.

Deccan shield faces risk of earthquakes

The Deccan shield regions, hitherto considered "stable" ones, are showing signs of having become "active" in respect of severe reservoir-induced (SRI) and stable continental region (SCR) earthquakes for over three decades, according to Dr Harsh K Gupta, director of the National geological research institute (NGRI).

Seminar on cretaceous geology systems

An international seminar on "Cretaceous Geology System,"is being organised by the ONGC at Chennai from January 6-8. Cretaceous systems are rock formations 65 million to 135 million years old. These rock systems are petroleum sources.

A conjunction that changed Earth's climate

Two scientists now claim that a better under-standing of the Earth's baroque climate system requires a better understanding of the interaction between the shape of our evolving planet and the movements of other bodies in the Solar system.

Breakthrough in quake predictions

A breakthrough in earthquake prediction through mathematical statistics, an advanced branch of stochastic and processes, has now come very close to predicting earthquakes and seaquakes, thanks to the scholastic ammunition of Brownian motion like behaviour of random stresses due to defect dynamics. At an international conference on "Recent Advances in …

Study reveals major seismic fault in M. P.

The macroseismic and aftershock studies of last year's Jabalpur earthquake have revealed a "deep-rooted seismogenic fault" located within the Narmada south fault zone, according to J R Katyal, deputy director-general of the Geological Survey of India (GSI).

Warning signals for our planet

Scientists have found that the earth's atmosphere has shrunk by eight kilo metre in the last 40 years, possibly as a fall out of accumulation of green house gases. Researchers of the British Antarctic Survey in Cambridge, probing 40 years of data gathered at the Antarctic peninsula and the Falkland …

SEAWIFS completes a year of remarkable earth observations

For the first time in history, NASA is releasing dramatic images documenting the Earth's changing biology, both on land and in the oceans, as observed from space for one continuous year. The changing seasons of life, are being monitored by the Sea-viewing Wide Field-of-view Sensor (SeaWiFs) which was launched on …

US scientists say earth was just a snowball 700 million years ago

700 million years ago a shield of ice covered the earth from pole to pole making the world a giant snowball claim US scientists Paul Hoffman and Galen Halverson of Harvard University in Cambridge , Massachusetts. The rivers were frozen into glaciers and the oceans were covered by a closed …

High-magnitude quakes to rock NE after 2030

Parts of North-East India will witness highmagnitude earthquakes between 2030 and 2040 according to researchers from the University of Roorkee.

Deadly impact

studies reveal that a comet crashed into the Earth 370 million years ago, blasting a huge crater into the sea floor. Charles Sandberg, a geologist emeritus with the us Geological Survey, says this triggered 304 m waves that resulted in the extinction of many species. He feels that the crash …

Tracking Earth s movements

The time taken by the Earth to rotate fluctuates by milliseconds every day. Experts say that it might be due to atmospheric changes, high and low tides, and likely movements in the Earth's core that are constantly shifting the planet's mass. To keep track of the Earth's vagaries, scientists at …

The truth about an ocean

Most people would have heard about the mythical disappearance of Atlantis. Even researchers believe that the ancient Iapetus Ocean never existed at all. However, Warren Huff, a geologist at the University of Cincinnati, USA, has found evidence of a narrow Iapetus Ocean from ancient volcanic ash beds. He says that …

In Focus

The Pathfinder mission sprung a surprise towards end August when the roving vehicle revealed at least two different kinds of rocks on the planet. Neither resembles the Earth's volcanic rocks or meteorites presumed to originate in Mars. These findings have confused scientists, waiting for moredata on the rocks. They are …

Tunes from dunes

For years researchers have marvelled at the phenomenon of singing sands. Marcel Leach and Douglas Goldsack at Laurentian University in Sudbury, Canada have discovered that for sands to sing, they need to be coated with a layer of silica gel. After examining various types of sands they found that the …

Hippo fossil trail

It seemed to be a rough dirt road leading to nowhere. But these are the the remains of hippo trails leading to dried-up wallowing pools in a remote part of Tanzania. Hippos wallow in freshwater pools during the day to escape the sun. At night they plow through the mud …

An end to forecasting

earthquake-prediction programmes that blossomed in the rich countries in the 1960s failed in their objectives and were closed down. However, Japan's programme, spending us $145 million annually lived on. But now a report adopted by the Ministry of Education's Geodesy Council in Japan has admitted that Japanese geophysicists have no …

Volcanic after effects

the Hawaiian volcano of Mauna Loa supports an extraordinary range of climates and ecosystems. Yet the slopes of the volcano are constantly being resurfaced by the red-hot lava that destroys everything in its path. After an eruption, the cooled lava quickly becomes a home for plants

Breaking a myth

An international team of geologists led by Peter Davies of the University of Sydney feel that Australia's Great Barrier Reef is a lot younger than what it is believed to be. It may have been part of the driving force behind a mysteriously hot period on Earth around 4,00,000 years …
