      Nicaragua launches construction of inter-oceanic canal

      The Chinese firm HKND has a contract to build the 173-mile long Nicaraguan Canal, which will connect Caribbean and the Pacific, and operate it for 50 years.

      From BBC

      Nicaragua has announced the start of work on a new canal linking the Atlantic and Pacific Oceans.

      At an opening ceremony, Wang Jing, the president of HKND, the Chinese company building the canal, said this moment would go down in history.
      The 278km (172 mile) waterway will be longer, deeper and wider than the Panama Canal.

      But critics fear a negative environmental impact and doubt its viability and economic benefits.
      The Grand Canal of Nicaragua, as it has been called, aims to rival Panama's waterway and lift the country out of poverty.

      The opening ceremony was largely symbolic, as work began on an access road for machinery needed to build a port for the canal on Nicaragua's Pacific coast.
      Nicaragua's Vice-President Omar Halleslevens said the canal would change the history and the economy of Nicaragua, one of Latin America's poorest countries.
      "With this great canal, Nicaragua expects to move 5% of the world's commerce that moves by sea, which will bring great economic benefits and double the GDP (gross domestic product),'' said Mr Halleslevens.

      There is a clear sense of expectation here, where the construction of a man made passage between the Pacific and Atlantic oceans designed to dwarf the Panama Canal has officially begun.

      But there is also tension: over the past few weeks protests against the canal have increased.
      And the authorities' decision to hold the main groundbreaking ceremony in Managua, some 120km away from where the waterway is to built, won't help convince the many sceptics who still doubt the project's viability.

      The government claims that the project, awarded to a Hong Kong based international consortium, will finally lift the Western hemisphere's second poorest country out of poverty.

      But many fear environmental damage may outweigh the economic benefit, or oppose the extremely generous terms offered to the Chinese investors.
      Those who live on the projected route simply don't want to lose their land and livelihoods.

      HKND says it expects the project to be finished within five years and operational by 2020, and to cost about $50bn (£32bn).
      The project is to include two ports, an airport, a resort and an economic zone for electricity and other companies.

      But some have questioned the canal's financial soundness and allege that Wang Jing lacks experience in developing or financing big infrastructure projects.
      Opponents are also concerned about the impact construction may have on Lake Nicaragua and on poor communities in the area.
      The route announced in July would pass through the lake, an important source of fresh water.
      Environmentalists have warned of the risks of damming rivers and moving large amounts of soil. Communities along the route have staged protests.

      Tsunami-hit nations mark anniversary

       Significant advances have been made in tsunami detection and forecasting
      since the Great Indian Ocean (Sumatra) Tsunami of 2004. 

      From BBC

      A decade ago, one of the largest earthquakes ever recorded struck off the coast of Indonesia, triggering a tsunami that swept away entire communities around the Indian Ocean.
      About 228,000 people were killed as a result of the 9.1 magnitude quake and the giant waves that slammed into coastlines on 26 December 2004.
      The violent upward thrust of the ocean floor at 07:58 local time (00:58 GMT) displaced billions of tonnes of seawater, which then raced towards shorelines at terrifying speeds.
      The waves stripped vegetation from mountain sides hundreds of metres inland, capsized freighters and threw boats into trees. The estimated cost of the damage was just under $10bn (£6.4bn).
      Ten years on, many coastal towns and villages have rebuilt their communities and lives. The shores of Indonesia and Thailand, left ravaged by the tsunami, appear transformed.

      How the wave spread: 26 December 2004
      After the quake struck, the resulting tsunami radiated across the Indian Ocean, from Indonesia to Sri Lanka and beyond.

      The quake ruptured the greatest fault length of any recorded, spanning a distance of an estimated 1,500km (900 miles) - longer than the US state of California.
      The rupture started beneath the quake's epicentre and progressed northward along the fault at about 2km/sec (1.2 miles/second) - lasting about 10 minutes - according to the Tectonics Observatory at the California Institute of Technology.
      The length of the rupture meant that the waves reached a wider geographical area - as far afield as Mexico, Chile, and the Arctic.
      The waves travelled at speeds of up to 800km/h (500mph).

      Computer modelling after the tsunami, estimated that waves had reached a height of almost 20m (65ft) in some areas.

      However, scientists investigating damage in Aceh, Indonesia found subsequent evidence that waves had reached 20-30m (65-100ft) in places.
      Despite there being several hours between the earthquake and the impact of the tsunami, nearly all the victims were taken completely by surprise. With no adequate warning systems in place, there was no alert issued to people to seek safety.
      In the aftermath of the disaster, the Indian Ocean Tsunami Warning and Mitigation System was formed to detect seismological changes and provide warnings of approaching waves.
      However, on the 10th anniversary of the disaster, risk experts and UN officials have warned weaknesses remain in the system, particularly regarding the communication of warnings at local level.
