ABSTRACT:
The weather of March 2010 of Visakhapatnam has been one of a great theoretical interest. The plain analysis of the Earth tremor that rocked the city and various parts of the Andhra Pradesh coastal areas seems very perplexing and intriguing. The author concludes that the tremor waves are a complex superposition of different thrusts and indicates the source of the earthquake itself was a composite event. Whether the origin of it is a simple upsurge of the mantle or the involved pattern of sequence and consequent events at the crust and mantle boundary is very intriguing. The evidence that the precursor signals of the deep earthquake have been found as much as fifteen to twenty days earlier is very significant finding. The continued study of the weather pattern by the present author has added new dimensions of analysis of this composite event earthquake. The present article summarises several events that have occurred in the Month of March 2010. No cohesive picture could however be drawn due to the diverse aspects of the atmosphere and the stratosphere interactions and the injection of new entities into the local atmosphere by varied and a variety of source physical events.
Keywords: tremors, complex waves composite event, earthquake of a diverse nature, meteorology, geophysics, stratosphere, multitude flowers, natural spectrums.
A SUMMARY REPORT:
The onset of high temperatures throughout Andhra Pradesh and the pleasant and windy atmosphere at Visakhapatnam were contrasting features that went unnoticed by many an experts of weather and the geo-meteorological scientists. The trees and other living organisms can perceive the weather, in much more subtle way than a human being geared with his ultra-modern sensitive CCD and Silicon chip gadgets. From the 1st March 2010 onwards certain areas of Andhra Pradesh have been experience very hot summer weather with temperatures above 2 to 3 degrees above the averages. The Algona district has been damaged by Hailstorms extending over an area of 300 acres of land by 60% and another 200acres by 50%. There was a hailstorm that divested Srikakulum town and neighbouring places for about an hour.

The occurrence of the earth tremors at Visakhapatnam has been preceded by the shrieking hauling of the stray dogs on the street and especially on the 29th March 2010 at 4.02AM. The author has made successful sound recordings of the stray dogs on the 27th March 2010 at 23hrs 41m night time and again at 23h44m as well on the 28th March 2010 at 0017am i.e. the morning of 29th March 2010. Surprisingly the onset of earth tremor experienced at Visakhapatnam has been preceded by the shrieking hauling of dogs on the 3rd March 2010 at 01 00 hrs and followed by just 15 minutes again. These sound records made at the author’s residence are available for no-profit price from the author.
Visakhapatnam on the Tuesday, 30th March 2010 at 10:25.p.m experienced two slight tremors of 6.8R that lasted for a few seconds. Some say at 10:23 PM and others at 10:30PM. There was a failure of current supply for nearly 10 minutes in official colony. The earth tremor was felt dispersed over a wide area extending from Srikakulum in A.P. to Tamil Nadu coast. The AU Girls Hostel situated on the top of hill and the AU Campus residents have felt the tremors. The neighbouring people near the collectors claim to have felt it while surprisingly the people residing in the Official Colony Maharanipeta haven’t experienced it at all. But people in Simhachalam, Gurudwara, Sitampeta, Seethmadara, Pendurthy, Parwada (thanam village) Murali Nagar, Airport area, assert that tremor was more intensive than the earlier experienced a few years ago. Alert-wise it is important to note that the tremor moved the earth at the RK beach and moved over to the Siripuram junction hilly area affecting the AU HOSTEL for Girls. Also it moved over Madugulu, Chodavaram and Paderu. The intensity was more than that experienced about four months ago.
A volcano erupted beside a glacier in southern Iceland, Iceland’s civil protection agency said on Sunday. The eruption occurred around 11:30 p.m. on Saturday (1930 EDT) beside the Eyjafjallajokull glacier, the fifth largest in Iceland. Scientists can see lava flows in the half—mile (1—kilometer) long fissure, and authorities are watching for further activity. It did not occur below ice, lessening the chances of flooding from a glacier melt. Evacuees in the village of Hella have been provided shelters.
On the Saturday 27th March 2010 3tons weighing fish of various kinds, about 50, have been caught by the local fisher men an event of unusual nature since they are usual catch of fish is only about half a ton. The variety of fish caught was amazing and consist of octopus, jelly fish, power fish, devil fish, glowfil, sebial, veligo, vatic bulls and apart from ’pitalu and royyalu’. They were washed driven to the near shore by the cold sea water currents and due to the dredging operations.
On this fateful Tuesday the North-East India had heavy rain and the weather marker trough ran down from Bihar to North West Bengal even as facilitating the western disturbances of weather in Jammu & Kashmir. Thunderstorms in the Himalayan region and its foot hills would experience till the April 6th over on to the North East. Rain in Kerala, Karnataka, and Andaman & Nicobar Island would last due to the remnant easterlies. But the heat-wave is persisting in Rajasthan, South Utter Pradesh, North Madhya Pradesh, with maximum temperatures well above the normal by 3 to 4 degrees Celsius. Over Maharashtra and part of extreme peninsular India the temperatures are 2 to 3 degrees above the normal. Also on March 27th, 2010 at the residence of Dubai Ramulu in Dhanwad, a sunflower plant of three months old bloomed with 14 flowers. This Saturday the many coastal towns especially the Visakhapatnam port and other areas plunged into a fog. This lasted from 6AM to 7.30AM and people in white dress found their clothes turned black. On the 17th March 2010 the rare Olive Ridley tortoise laid eggs on the sea/river mouth at Berhampur. Many more haven’t ventured to lay the eggs. March 17th report states that the underwater wells have become dry and the 300acres of maize, 150 acres of sesame and 200 acres of flowers and vegetables practically went dry with no supply of water. The villages affected were bani, kusulawada, vallali, peddapuram, anandapuram, jaganadhapuram, gutupalli, bakurpalem, butupalli, podugupalem etc.Turkey experienced an earthquake jolt of 6R that lasted a minute, on Monday 8th March 2010, at 4:30 AM. Ananthapuram and Nandhyal had a heat wave since 8th March 2010 and people were afraid to move out after even 8.A.M.
Given in the above figure are the Weather patterns of Visakhapatnam sky in the evenings of 14th March 2010 and 28th March 2010 at 17:42p.m & 18:24:57 respectively. Also the Figure depicts the evening sky views at 17:24 p.m of 28th March 2010 and 17:26.p.m of 28th March 2010 reflecting the dust scattering on the Bronze statue at the Beach. More fascinating and evidently obvious of the loaded sky with the debris of the onset of an earth tremor in The pictures of the moon light excellently recorded on the evening of 28th March 2010 respectively at 17:51.p.m; 18:08 .p.m and at 17:53.p.m. Of these the one taken at 17:53.p.m vividly portraits the fine dust of the earth tremor on set. It may be regarded as one of the prize worthy photo from purely a scientific view point.
The dust clouds at low levels and the dust spread dispersed at the higher levels of the atmosphere extending over to the stratosphere height is obvious. Weather pattern at Visakhapatnam in the month of March 2010 was one of a twisted temperature profile, with the sky completely engulfed by the deep earth quake features of the Andaman & Nicobar Islands epicentre. On the 27th March 2010 night the moon was engulfed in both white and dark cloud entities. The clouds have passed over the moon at 21 17 pm. The cloud thickness and density was yet times so much as to absorb the entire moon light.
