Before 2012 Or After 2012


As the dust settles down on the Iceland volcano and fights resume over Europe, those who travel frequently ask the question:How long will it be before the volcano starts erupting again? Iceland's volcano are known to be unpredictable, and there is a chance that this one keep blowing ash intermittently for a year.

Vulcanologist say that volcanoes will keep erupting in many places around the world, sometimes violently and some times less so. Once in a while-probably once in a century-a volcano will erupt with major force, throwing enormous qualities of ash into the atmosphere and impacting world climate significantly. A truly catastrophic eruption takes place less frequently- may be once in a few millennium-decimating large continents and plugging the world into a serious crisis for a while.

The Iceland volcanic eruption, near Eyajafjalla-joekull glacier, is a reminder that such eruptions, is a reminder that such eruptions, although rarer than earth-quakes, can have global consequences and need to be watched. Luckily for us, Volcanoes , unlike earth-quake give warning. The magnum has to come up and this process deformes the ground.
A volcano that is about to blow also tends to spew gases and produce earthquakes. "A volcanic eruption is often preceded by a swarm of earthquakes, sometimes a thousand small ones". Such earthquakes are not noticed by people but seismographs often pick them up.

Fortunately for us, prediction of volcanic eruptions has improved dramatically in recent times. Seismographs around the world pick up charges in seismic activity. Satellites can notice any ground deformation that precedes eruption."Satellites can monitor volcanoes around the world,"- This is useful because there is no ground observation for volcanoes in many countries.

Techniques such as interferometry can now pick up the tiniest of ground deformations around the world, provided we look when they happen. There is a rule of thumb in volcano logy: the longer the duration between two eruption, the more violent the eruption is likely to be. A big eruption is likely to happen at a place that has not seen eruption for a long time."- So, we need to build redundancies and not rely on one mode of transport.
Be that as it may, how do we make society take the threat seriously?

Man V/S Wild


The Nature has always made species to struggle for life. Thus, through Darwin's Theory of Natural Selection we all know that the better fitted species survives by struggling between the intermediate one. But among all of the species,Human-beings are most sensible and the most powerful one with the highest cranial capacity. But still we lack our Humanity to get fitted on the top of the table. Human's have always been playing a -ve (negative) influence in Nature by relatively destroying its own ecosystem by killing different animals just for sake of fun & money. We can get a better picture when we read the daily magazines & News papers, where we can see how long humans have gone to fulfill there basic needs of Life.Government though makes rules- But who follows it???, No one.... We have been an Evil to our lower vertebrates. Cant we imagine when in TV we see the adds of indiscriminate killing of our National Animal- Tiger are been striped out from there roots. Just 1411 are left in India- though its our National property. yet, the killing continues. We must wake up and protect this Evil from costing further damages. So, that the Tigers could also live a free life as us. The Government must take serious steps on the activities of the poachers and lie heavy meant rules for the killing of animals. Otherwise the days are not so far that 1411 would convert to 1 left. So, just protect your nature and do the needful.
