The earthquake triggered giant tsunami waves washed away almost anything and everything coming in its way, in some of the places upto 10 km inland. The J apanese   N ational P olice A gency   has confirmed over 13000 deaths and many more injured or missing. The multiple disasters further caused extensive and severe damage to over 125000 buildings,   roads, railways as well as fires in many areas. The worst however was the effect on F ukushima D ai-ichi N uclear P ower P lant (NPP). Though the structure could survive the “strong ground motion” and shut down automatically, failure of ancillary system to cool the reactors (necessary to remove  decay heat  after the reactor has been shut down, and to maintain spent fuel pools) resulted in multiple explosions creating a pa...

They are found in the inter-tidal zones along the coasts, bays, estuaries, lagoons, creeks and backwaters which are exposed during low tide and flooded by sea during high tide everyday. Globally there are nearly 70 species of true mangroves found dominating three quarters of the tropical coastline.   Ind...
