Deep earth pumps contributes to Earth Quakes

The Scientists have discovered natural deep earth pumps and that contributes to earth quakes. The discovery was made by examining one millimeter sized cubes of exposed rock in Alice Springs, which was deformed around 320 million years ago during a period of natural mountain formation. The evidence is described in a paper published in the latest edition of Nature entitled Creep cavitation can establish a dynamic granular fluid pump in ductile shear zones.

Research leader Dr Florian Fusseis, from the University of Western Australia, said that the discovery could provide valuable information in understanding how earthquakes are formed. Dr Fusseis said, While we understand reasonably well why earthquakes happen in general, due to stress build-up caused by motions of tectonic plates, the triggering of earthquakes is much more complex.

The process, called creep cavitation, involves fluid being pumped through pores in deformed rock in mid-crustal sheer zones, which are approximately 15 km below the Earth’s surface. The fluid transfer through the middle crust also plays a key role in tectonic plate movement and mantle degassing.

The discovery was made possible through the use of high-resolution Synchrotron X-ray tomographic, scanning electron microscope observations at the nanoscale and advanced visualisation using iVEC in Western Australia.

To understand the ‘where’ and ‘when’ of earthquakes, the ‘how’ needs to be understood first. We know that earthquakes nucleate by failure on a small part of a shear zone. Dr Fusseis said that while their sample did not record an earthquake it gave them an insight into the structures that could be very small and localized precursors of seismic failure planes.

OPERA has entered into Cloud Computing Technology

OPERA has entered into Cloud Computing Technology. With Opera 10, the introduction of a new technology called Opera Unite, radically extending what you are able to do online. Opera Unite harnesses the power of today’s fast connections and hardware, allowing all of us to help define the future landscape of the Web, one computer at a time. Opera Unite allows you to easily share your data: photos, music, notes and other files. You can even run chat rooms and host entire Web sites with Opera Unite. It puts the power of a Web server in your browser, giving you greater privacy and flexibility than other online services.

Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. The term cloud is used as a metaphor for the Internet, based on how the Internet is depicted in computer network diagrams and is an abstraction for the complex infrastructure it conceals.

Users need not have knowledge of, expertise in, or control over the technology infrastructure in the "cloud" that supports them.

Total solar eclipse of this century on Wednesday 22 July 2009

The total solar eclipse of this century is going to occur On Wednesday 22 July 2009. This could be a longest duration solar eclipse of this century. Consequently, it provides a rare opportunity to view and study this grand spectacle of nature. The partial phase of the eclipse will be visible throughout the country. In general, the partial phase can be seen in the regions of eastern Asia and Pacific Ocean. Considering the Earth as a whole, the eclipse begins at 5:28 a.m. when the shadow of the Moon touches the Earth at local sunrise at a point in the Arabian Sea close to the western coast of India.

The shadow crosses over central India, passes through south-east of Nepal, crosses North Bengal, southern part of Sikkim, most of Bhutan and north-western tip of Bangladesh. Then the shadow enters Assam and Arunachal Pradesh, touches Myanmar and enters China.

The eclipse ends at 10:42 a.m. when Moon's shadow finally leaves the Earth at local sunset at a point in the South Pacific Ocean. At approximately 6:23 a.m., the central path of the eclipse will touch the Earth at sunrise at a point in the Gulf of Khmbhat in the Arabian Sea near the southern coast of Gujarat. At this time, the path of totality will be about 200 km wide and the duration of totality at the central line will be about three minute 30 seconds.

This eclipse is of special interest for the scientists and general public as its path of totality passes through thickly populated regions of west, central, east and north-east India. The maximum duration of totality of 6 minutes 44 seconds occurs at 8:05 a.m. in the North Pacific Ocean where the width of the path is about 258 km. The rest of the path does not pass through major land areas.
