India’s Lone Volcano is Active

barren-island-story-fb_647_021917121026India’s only live volcano+ in the Andaman and Nicobar Islands is active again and started spewing smoke and lava again.

After lying dormant for 150 years, Barren Island volcano erupted in 1991 and has been showing sporadic activity since then, scientists of Goabased National Institute of Oceanography (NIO) said.

The volcano is erupting in small episodes of five to 10 minutes.During the day, only ash clouds were observed. But after sundown, red lava foundations were spewing from the crater into the atmosphere and hot lava streamed down the slopes.

Researchers from Council of Scientific & Industrial Research (CSIR) and NIO have sampled sediments and water in the vicinity and recovered coal-like black pyroclastic material representing proximal volcanic ejecta.

Scientists  are checking the composition of the lava and powdering the black sand to figure out the components. The Andaman basin is an active back-arc spreading basin known for strong seismicity, submarine volcanoes and hydrothermal activity.

 Scientists from CSIR-NIO have been surveying the basin and have identified several small submerged volcanoes in a linear chain called a volcanic arc.

An Enviable Feat:India puts record 104 satellites into orbit, in one go Including 103 Nano Satellites-Age of Nano Satellites is Here

90f62f3b17314bb48ebe0e45d9c531ae_6In an enviable feet,India has successfully launched record 104 satellites from a single rocket into orbit on Wednesday, in the latest triumph for its famously economical space agency.The launch was done with the help of indigenous Polar Satellite Launch Vehicle (PSLV).

The rocket took off at 9:28am  today (03:58 GMT) and cruised at a speed of 27,000km per hour, ejecting all the 104 satellites into orbit in around 30 minutes, according to ISRO.

PSLV first injected its main payload Cartosat- 2 series, India’s indigenously built earth observation satellite. It was followed by two other nanosatellites of Isro —- INS-1A and INS-1B.

!01 nano satellites are from other countries, including Israel, Kazakhstan, The Netherlands, Switzerland, United Arab Emirates and 96 from the United States.

Seventeen minutes after launch the rocket started placing the satellites into orbit, one by one with a time-frame of about 11 minutes.

The launch means India now holds the record for launching the most satellites in one go, surpassing Russia which launched 39 satellites in a single mission in June 2014.

The rocket was launched from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.

Human Ocean at Taj

2017-02-12-16-20-56Taj is  breathtaking. It has a magnificent pull on people. Because of this pull people flock to the Taj. I visited and there was an ocean of humanity there. Compare it will earlier picture and you may notice the difference.On this rate, in some days the crowd will be impossible to manage.

Urban Settlements/Systems Defined

A Human Settlement is a place where people live and interact through activities such as agriculture, trading and entertainment

A rural settlement system is a community involved predominantly primary activities such as farming, lumbering and mining.

An urban settlement system engages in predominantly in secondary and tertiary activities such as food processing and banking.

There is often correlation between functions, population sizes and population density.

A rural settlement tends to have small population and low population density.

Urban settlement often has a large population size and high population density.

Site Factors for Settlement

Physical environment determine the site of a settlement depend on

1.Water supply – water is essential for human survival and agricultural activities.

2.Relief – the availability of broad flat land such as floodplains promote agricultural activities.

3.Soils- fertility of soils also another considerations for agricultural activities

4.Shelter-which are sheltered from natural elements. Windswept highland with harsh cold climate are conducive for settlement.

5.Defence– Threat from enemies and predatory animals drove people to live together for protection.
