Earthquake in Sikkim & history

Earthquake history

The earthquake activity in this region is due to the Indian plate diving (thrusting) beneath the Eurasian plate. The state is mainly mountainous and underlain by several thrust faults. Most significant are the Main Boundary Thrust (MBT), the Main Central Thrust (MCT) and the Himalayan Frontal Thrust (HFF).

Seismic Hazard

All districts of the state of Sikkim lie in Zone IV. Since the earthquake database in India is still incomplete, especially with regards to earthquakes prior to the historical period (before 1800 A.D.), these zones offer a rough guide of the earthquake hazard in any particular region and need to be regularly updated .

HIGH COURT RAP FOR CENTRAL GOVT AND STATE GOVERNMENT OVER GTA PACT

KOLKATA, 17 SEPT: Calcutta High Court criticised the state government and Union government on Friday, for failing to address issues relating to the impact of an alleged influx of people from Nepal on demographics in India. The criticism comes long after the ink has dried on the memorandum of agreement (MoA) between the state, Union Government and the Gorkha Jan Mukti Morcha (GJMM) for the formation of Gorkha Territorial Administration (GTA).

“The matter is extremely serious in nature. The respondents are taking the matter very lightly,” the Division Bench of Chief Justice Mr Justice JN Patel and Mr Justice Asim Roy said during a public interest litigation (PIL) hearing on the misutilisation of Articles six and seven of the Indo-Nepal Treaty of 1950, which some say is leading to an influx of people of Nepali origin to India.

The provisions in these Articles confer exclusive and restricted national treatment to the treaty beneficiaries in India and Nepal.

According to the PIL, which was submitted by Mr Kallol Guha Thakurta and moved by Jan Chetna, a Siliguri-based voluntary organisation, an increasing number of people of Nepali origin are coming to India and enrolling themselves on the voters’ list in many constituencies in Darjeeling, Kalimpong, Kurseong and parts of the Dooars in West Bengal,

Resentment among people of non-Nepali origin about the inclusion of certain areas in the GTA's jurisdiction was manifested in a bandh in Siliguri. The bandh was part of a two-day agitation that took place on the day the MoA was signed. Several organisations are opposed to the GJMM’s demand for inclusion of eight wards from the Siliguri Municipal Corporation and 196 moujas each from the Terai and the Dooars in the GTA's jurisdiction.

The Election Commission has failed to prevent this illegal inclusion, it was submitted. It is violating Article 326 of the Constitution which deals with adult suffrage. Under the Indo-Nepal-Great Britain tripartite agreement in 1947, soldiers who are subjects of Nepal recruited in certain Gorkha regiments are debarred from possessing voting rights in India, it had been submitted. Their progeny is also not given this right.

Besides entering India from Nepal, a sizeable number of persons of Nepali origin are going to Bhutan and then coming over to India, it was submitted. As there is no extradition treaty between India and Bhutan, these people are not registered as foreigners. It was further submitted that there is rising apprehension that north Bengal and north east India will at a point of time be swamped by them.

The issue of the change of demographic pattern is a significant factor in the inclusion of area under Gorkha Terriotorial Administration's (GTA) jurisdiction. Incidentally, the director of census operations is a member of the high-powered committee which had been formed to look into the issue of identification of GTA's area from Siliguri, Terai and Dooars, keeping in mind the “compactness, contiguity, homogeneity and ground-level situations.”

 

Courtsey : The Statesman

The GJMM is paying households of Dooars & Terai Rs 30 a day to hoist the flag of GJMM before the survey, villagers alleged.

From rooftop to rooftop, on treetops, on shops and in the middle of tea gardens, the flag of the Gorkha Janmukti Morcha today flutters across much of the Dooars and the Terai plains, a visual makeover ahead of a government survey to assess the strength of the GJM’s claim on this territory.

Most of the flags have come up over the past month, irrespective of whether those living in the houses are ...Gorkas or Adivasis. This was after GJM chief Bimal Gurung issued a diktat not only to Gorkhas but also to Adivasis “who want to come under the Gorkha Territorial Administration”.

It is meant to be a show of numerical supremacy ahead of the planned visit by survey teams, which will be constituted by a committee comprising retired Calcutta judge Shyamal Sen, GJM representatives and those of the state and Central governments, to determine which areas should come under the GTA. The GJM has demanded nearly 400 mouzas in the plains — around 200 each in the Dooars and the Terai — in addition to the entire hill subdivisions of Darjeeling, Kalimpong and Kurseong.

At Malbazar, Nagrakata and Banarhat in the Dooars, areas dominated by Adivasis, the display is the result of a combination of fear and alleged incentive. The GJM has been paying households Rs 30 a day to hoist the flag, villagers alleged.

Robinson, a tea labourer at Banarhat, said he has hoisted the flag because he could not afford not to. “We don’t want to be included in the GTA. We are Adivasis, living here for decades, but so many Nepalese and Bhutanese people have settled here that we are now almost reduced to a minority. Since they have put the GJM flag on their roofs, we have to do the same.”

Binay Tigga, another labourer, admitted he was being paid. “For the last one month, we are being given Rs 30 a day. They call us ‘the 67 people’ because our daily wage is Rs 67 while tea labourers in Darjeeling get Rs 90. They have told us that for a couple of months, till the survey is done, we can earn Rs 97, which is more than what tea labourers in Darjeeling earn.”

Shortly after the notification for the joint verification committee had been issued, Gurung made a speech at Nagrakata, where he announced the diktat on the flags and said that every resident must be home when the survey teams come calling.

A senior member of the GJM central committee conceded, “We are concerned about the Dooars region since it is a traditional stronghold of the Adivasis. To influence the views of the committee, our leaders have urged the people to put up GJM flags on their houses.”

Leaders among the Adivasis are fuming. Jhon Barla, block president (Banarhat-Nagrakata) of the All Bengal Adivasi Vikash Parishad, said, “The committee comprises only representatives from the government and the GJM. The ABAVP and other groups have not been made a party to this. Adivasis will never allow such a demarcation.” He also wondered where the GJM has found funding for the Rs 30 allegedly being paid to each Adivasi household every day.

The committee, formed on July 29, met for the first time on August 31. It then decided to publish a newspaper advertisement seeking suggestions and complaints, if any, but is yet to do so. Given six months to submit a report, it has decided to meet again in November.

ILLEGAL FORMATION OF THE NEW BOARD OF SILIGURI JALPAIGURI DEVELOPMENT AUTHORITY

The decision to keep the Siliguri and Jalpaiguri civic chiefs out of the development authority for the two towns has not gone down well with at least one of them.

Only one Congress representative is on the 12-member board which has at least five Trinamul leaders.

 The Congress chairperson of the Jalpaiguri municipality, Mohan Bose, has questioned how he and Siliguri mayor Gangotri Datta could have been left out of the board of the Siliguri Jalpaiguri Development Authority. The civic chiefs have been on the SJDA board since it was first formed in 1980.

Today, SJDA chairperson and Siliguri MLA Rudranath Bhattacharya announced that a 12-member board including him and the chief executive officer of the development authority as member-secretary has been formed.

"We were told about the formation of the new SJDA board by the principal secretary of state urban development department on September 9. The new members would be informed about their selection so that they can carry out necessary duties and responsibilities in the future days," Bhattacharya said.

The other 10 members on the board are the district magistrates of Darjeeling and Jalpaiguri, the principal secretary of the urban development department, the divisional commissioner of Jalpaiguri, the MLAs of Matigara-Naxalbari and Rajganj Shankar Malakar and Khageswar Roy, Siliguri deputy mayor Ranjan Silsharma and Trinamul leaders Jyotsna Agarwal and Chandan Bhowmik. The 12th member is Nantu Saha, SJDA chairperson said, but could not furnish details on him.

"As far as my knowledge goes, there are laid down rules that the civic chiefs of towns which come within the ambit of the development authority should be members. Any change in the composition of the board has to be made through a gazette notification and till date, we do not have information of any such notification," said Bose. The reaction from Gangotri was mild. "We cannot comment on the SJDA board," she said.

Malakar is the only Congress member on the board. Asked why the MLA and MP of Jalpaiguri and the sabhadhipatis of Siliguri mahakuma parishad and Jalpaiguri zilla parishad were left out, Bhattacharya said: "A board has been formed and it would be wrong to interpret its composition in terms of political colours."



But many pointed out that when the SJDA was under the Left Front, Congress leaders like Mohan Bose and Gangotri had been on the board. "This time Jalpaiguri MLA Sukhbilash Burma, Alipurduar MLA Debprasad Roy, Phansidewa MLA Sunil Tirkey have been left out. All of them are from the Congress, not even from the Left. Last time, Debprasad Roy, Mohan Bose, Gangotri Datta were all on the board despite being from the Opposition party," said a source.
