The catastrophic death toll in Asia caused by a massive tsunami might have been reduced had India and Sri Lanka been part of an international warning system designed to warn coastal communities about potentially deadly waves, scientists say.
At least 10,000 people in India and Sri Lanka were among the nearly 23,000 killed after being hit by walls of water triggered by a tremendous earthquake early on Sunday off Sumatra.
The warning system is designed to alert nations that potentially destructive waves may hit their coastlines within three to 14 hours. Scientists said seismic networks recorded Sunday's massive earthquake, but without wave sensors in the region, there was no way to determine the direction a tsunami would travel.
A single wave station south of the earthquake's epicenter registered tsunami activity less than 60cm high heading south toward Australia, researchers said.
The waves also struck resort beaches on the west coast of Thailand's south peninsula, killing hundreds. Although Thailand belongs to the international tsunami-warning network, its west coast does not have the system's wave sensors mounted on ocean buoys.
The northern tip of the earthquake fault is located near the Andaman Islands, and tsunamis appear to have rushed eastward toward the Thai resort of Phuket on Sunday morning when the community was just stirring.
"They had no tidal gauges and they had no warning," said Waverly Person, a geophysicist at the National Earthquake Information Center in Golden, Colorado, which monitors seismic activity worldwide. "There are no buoys in the Indian Ocean and that's where this tsunami occurred," he said.
The tsunami was triggered by the most powerful earthquake recorded in the past 40 years.
The earthquake, whose magnitude was a staggering 9.0, unleashed walls of water more than two storeys high to the west across the Bay of Bengal, slamming into coastal communities 1,600km away. Hours after the quake, Sumatra was struck by a series of powerful aftershocks.
Researchers say the earthquake broke on a fault line deep off the Sumatra coast, running north and south for about 965km or as far north as the Andaman and Nicobar islands between India and Myanmar.
"It's a huge rupture," said Charles McCreery, director of the Pacific Tsunami Warning Center near Honolulu. "It's conceivable that the sea floor deformed all the way along that rupture, and that's what initiates tsunamis."
Tsunamis as large and destructive as Sunday's typically happen only a few times in a century.
A tsunami is not a single wave, but a series of traveling ocean waves generated by geological disturbances near or below the ocean floor. These waves can race across the ocean like the crack of a bullwhip, gaining momentum over thousands of kilometers.
Most tidal waves are triggered by earthquakes and volcanoes.
END OF AN ERA: The vote brings the curtain down on 20 years of socialist rule, which began in 2005 when Evo Morales, an indigenous coca farmer, was elected president A center-right senator and a right-wing former president are to advance to a run-off for Bolivia’s presidency after the first round of elections on Sunday, marking the end of two decades of leftist rule, preliminary official results showed. Bolivian Senator Rodrigo Paz was the surprise front-runner, with 32.15 percent of the vote cast in an election dominated by a deep economic crisis, results published by the electoral commission showed. He was followed by former Bolivian president Jorge “Tuto” Quiroga in second with 26.87 percent, according to results based on 92 percent of votes cast. Millionaire businessman Samuel Doria Medina, who had been tipped
ELECTION DISTRACTION? When attention shifted away from the fight against the militants to politics, losses and setbacks in the battlefield increased, an analyst said Recent clashes in Somalia’s semi-autonomous Jubaland region are alarming experts, exposing cracks in the country’s federal system and creating an opening for militant group al-Shabaab to gain ground. Following years of conflict, Somalia is a loose federation of five semi-autonomous member states — Puntland, Jubaland, Galmudug, Hirshabelle and South West — that maintain often fractious relations with the central government in the capital, Mogadishu. However, ahead of elections next year, Somalia has sought to assert control over its member states, which security analysts said has created gaps for al-Shabaab infiltration. Last week, two Somalian soldiers were killed in clashes between pro-government forces and
Ten cheetah cubs held in captivity since birth and destined for international wildlife trade markets have been rescued in Somaliland, a breakaway region of Somalia. They were all in stable condition despite all of them having been undernourished and limping due to being tied in captivity for months, said Laurie Marker, founder of the Cheetah Conservation Fund, which is caring for the cubs. One eight-month-old cub was unable to walk after been tied up for six months, while a five-month-old was “very malnourished [a bag of bones], with sores all over her body and full of botfly maggots which are under the
BRUSHED OFF: An ambassador to Australia previously said that Beijing does not see a reason to apologize for its naval exercises and military maneuvers in international areas China set off alarm bells in New Zealand when it dispatched powerful warships on unprecedented missions in the South Pacific without explanation, military documents showed. Beijing has spent years expanding its reach in the southern Pacific Ocean, courting island nations with new hospitals, freshly paved roads and generous offers of climate aid. However, these diplomatic efforts have increasingly been accompanied by more overt displays of military power. Three Chinese warships sailed the Tasman Sea between Australia and New Zealand in February, the first time such a task group had been sighted in those waters. “We have never seen vessels with this capability
