Tokyo, A total of 1464 people in Tokyo in July was taken to hospital as a result of air temperature increased sharply, rising from 359 people last year, according to the Tokyo Fire Department reported on Sunday.”The amount is so high is probably due to the air temperature exceeds 35 degrees Celsius for several days after the end of the rainy season before the body of people can adapt to the changing weather,” said an official at the Japan Meteorological Agency.

The rainy season ends on July 17. In July the highest temperature reached 30 degrees Celsius for 22 days.As many as 745 people were reported taken to hospitals because of heat wave since July 21. Due to changes in extreme weather, the Narima Ward, a resident of Tokyo’s 91-year-old died at his home and another 127 people in critical condition.

WELLINGTON, New Zealand A 5.9-magnitude earthquake hit near the Pacific island of Tonga on Thursday, but no casualties or damage were reported and no tsunami warning was issued.The quake struck 65 miles (135 kilometers) northeast of Hihifo, Tonga, at a depth of 21 miles (35 kilometers).Many residents of American Samoa felt the quake and went out to look at the ocean while listening to radio broadcasts.

“Nothing is registered on our censors for tsunami waves,” according to Carol Baqui, a forecaster with the American Samoa weather service.No tsunami warning was issued by the Pacific Tsunami Warning Center in Hawaii.

Police in the Samoan capital, Apia, said they had no reports on the temblor. “We didn’t feel any earthquake,” an officer, who declined to be named, said.Julie Dutton, a geophysicist with the U.S. Geological Survey in Golden, Colorado, it was a relatively small quake.”Right now we don’t have any reports of it being felt. It’s pretty far off the coast so we’re not anticipating anything damaging,” Dutton said.Preliminary estimates put the quake at 6.2, but that was later downgraded to 5.9.

A magnitude 8.0 earthquake close to neighboring Samoa last Sept. 29 killed 34 people in American Samoa, 183 in Samoa and nine in Tonga, when tsunami waves up to 46 feet (14 meters) high crashed ashore. It also created a sea floor fault up to 190 miles (300 kilometers) long and 23 feet (7 meters) deep.About 90 percent of the world’s temblors occur in the so-called “Ring of Fire” – an arc of earthquake and volcanic zones that stretches around the Pacific Rim.(AP)

Singapore  – An earthquake measuring 6.4 on the Richter Scale struck the region north of the Andaman Islands of India, Tuesday, but no reports of damage.An earthquake initially estimated at magnitude 6.9 on the Richter Scale occurred 137 miles north of Port Blair, the territory has ever hit by massive tsunami in 2004.

California Integrated Seismic Network United States (U.S.) said the quake occurred at a depth of 28.6 miles was not triggered a tsunami.Andaman India participate sensed tsunami impact terrible destroying partly Province territory Nangroe Aceh Darussalam (NAD) and Nias, Sumut, on December 26 2004.sunami 2004 which reportedly killed about 230 thousand people in eight countries was triggered by an earthquake measuring more than nine on the Richter Scale.( Reuters)

Queenslanders warned away from the waters edge with a series of ‘long waves’ expected to affect the coastline today. Hazardous coastal conditions are expected to continue for a number of days. Major surfing competitions have been delayed, home owners on the Gold Coast have been told to prepare for possible minor flooding on the tides.The tsunami warning remains in place for Queensland coastal areas from Point Danger to Saint Lawrence, including the bay areas. This Queensland Government site offers more information. Beaches are closed, with major surfing competitions delayed, and conditions are likely to remain hazardous for a couple of days according to Surf Life saving Queensland.

On the Gold Coast, Emergency Management Queensland has alerted home owners in the immediate foreshore and low lying areas to take precautions against possible minor flooding on the tides.Chris Ryan from the Joint Tsunami Warning Centre, explained today’s event as a series of effects rather than a single wave.”So it’s a number of long waves,” he said. “So we’ll keep watching the gauges and when we’re sure the danger has passed, we’ll cancel those warnings as quickly as we can.”

Meanwhile Life Guards and Surf Life Savers on the Sunshine Coast and as far north as Central Queensland are asking residents and holiday makers not to go sightseeing at the water’s edge. While the ocean level has only reason a matter of centimetres, there are millions of tonnes of water creating unusual currents and turbulence beneath the surface.The Gold Coast’s Senior Life Guard, Warren Young, expects the beaches to remain closed, as they have been since early this morning.

“It’s a bit of a spectator sport today,” he said, “Although there are board riders out getting a few good waves. Our biggest concern would be people walking with small children in the shallows, because it’s a lovely day here after yesterday’s rain.”The effects of the tsunami are moving steadily north along the Queensland coast and ships at sea have been contacted and told to remain in deep water, while small boat owners have been told to come ashore quickly as far north as Roslyn Bay.

Tokyo   Tsunami waves as tall as 120 centimeters hit the Pacific coast, the region Iwate, Japan, at around 13:46 pm. A total of 320 thousand Japanese residents were evacuated to safety. This was conveyed by Japan Meteorological Agency, as reported by AFP, Minggu (28/2/2010). Earlier Japan Meteorological Agency issued a tsunami warning of major coastal areas of Japan are in direct contact with the Pacific. The wave height is expected to reach more than 3 meters.

As a result of this tsunami, the Japanese evacuated the 320 thousand residents in the eastern coastal areas in contact with the Pacific Ocean, as areas Aomori, Iwate, and Miyagi. In the meantime, a northern port in Nemuro, Japan, affected by flooding caused by the tsunami. “Please do not go near any coastal region,” appealed the Prime Minister of Japan, Yukio Hatoyama, in particular national speech facing the threat of a tsunami caused by the earthquake Chile.

The first recorded tsunami waves as high as 10 centimeters Minamitori flicked a small island located 1.950 kilometers south of Tokyo. However, the height increasing until it reaches 120 centimeters. Japan Meteorological Agency warned that the wave height can be increased. The first wave may not be the biggest wave. Tsunami warning and seems to be valid for a long time. “The wave could reach the mainland, so for safety you must evacuate to higher ground from the estimated tsunami wave height,” says the Japan Meteorological Agency, Yasuo About a, warned citizens.

MOSCOW  Tsunami waves 0.8 meters tall destabilize Russia, precisely in the east coast of Russia, Kamchatka Peninsula, following a major earthquake in Chile. Lucky, it does not cause damage means.”No damage or casualties were reported,” said a spokesman for the Russian Ministry of Disaster as reported by Reuters on Sunday (28.2.2010).Although no major damage, some local residents have been evacuated to a location that is considered more secure.

As is known, Kamchatka is a region located on the eastern side of Russia. Where is the Soviet Union had not broken, the area became a military area. Now, the center of the platinum mines, gold, copper, and nickel.Previously, approximately hundreds to thousands of Japanese citizens were evacuated due to fear of tsunami waves as high as three meters, which made possible the country will shake the sunrise.The reason Japan Meteorological Agency said, waves as high as 10 centimeters, which is the impact of SR 8.8 quake recorded in Chile has touched Ogaswara Island, late afternoon.

An outgoing tide has eased the tsunami threat along Australia’s east coast, but authorities are still warning people to keep out of the water.Rising sea levels have been recorded at Norfolk Island, Southport in Tasmania and Port Kembla in New South Wales.A tsunami alert, issued after a massive earthquake in Chile, remains in place for Queensland, News South Wales, Victoria and Tasmania.Sea rises of 10 to 50 centimetres have spared coastlines, but officials warn there is still the risk posed by strong currents caused by accelerating tidal movements.

The Bureau of Meterology’s spokesman, Alasdair Hainsworth, says the threat is abating now the tide is on the way out.”We’re no longer talking about any kind of foreshore flooding. We’re simply now concerned about strong currents,” he said.Phil Campbell, from the NSW State Emergency Service, says beachgoers should not go swimming under any circumstances.”We’re advising people that they should not engage in any recreational boating in small boats, particularly as there are those strong currents that are likely to make that quite hazardous,” he said.

“For those people thinking of taking part in some rock fishing or fishing from beaches, we’d also recommend against those activites as well.”The weather bureau says the tsunami has not caused any measurable increase in wave movement in Queensland, but a marine alert remains current for the state’s waters north from the NSW border to St Lawrence.

South of Sydney, Port Kembla measured a rise of 10 to 15 centimetres above the water table, with water levels still increasing.The bureau says a second spike is being recorded at Norfolk Island, with the surge expected to continue towards Queensland.In Sydney, hundreds of people lined the promenade at Bondi Beach, waiting to see what impact the Chile earthquake would have on Australian shores.

Beachgoers were directed off the sand shortly before 8.30am AEDT and the beach was closed.But many people remained on the beach and in the water in defiance of the warnings.Surf Life Saving NSW says it is concerned several local councils have decided to open beaches despite the tsunami warning.Spokesman Steven Leahy says larger waves and stronger currents and rips are expected along the state’s coastline this afternoon.”Our advice is that the risk has not declined and in fact over the next couple of hours there is still every possibility that we will see some tsunami event,” he said.

TasmaniaElsewhere, the tsunami warning forced the cancellation of surf lifesaving activities on Tasmania’s east coast and southern beaches.The first signs of the tsunami in Tasmania were recorded at Maria Island off the state’s south-east coast, just after 8:00am (AEDT).

The weather bureau says the waves were expected to get bigger, and Marine Safety Tasmania says people should delay launching boats until the threat passed.It is considered unlikely the tsunami will have an effect on land.Much of Australia’s east coast was put on tsunami alert late yesterday with boats urged to return to harbour.The alert was issued after a massive 8.8 magnitude quake hit Chile, killing hundreds of people and sending giant waves speeding across the Pacific.Meanwhile, waves up to 1.5 metres high rammed into New Zealand’s east coast.

SEASIDE, Ore. Amid the hundreds of people who walked up and down the promenade overlooking the Oregon coast at Seaside on Saturday was one man on a mission.”Is there anything you’d like to know about tsunamis?” Patrick Corcoran said as he approached passersby toting shopping bags or walking their dogs.In many cases, the answer was yes. Thus began a series of impromptu lectures on big waves, subduction zones and the real tsunami danger in the Pacific Northwest: not far-off quakes, but close-up ones.”These distant-event tsunamis are really nothing, and we tend to overemphasize them,” Corcoran said. “If people come away from this thinking tsunamis on the Oregon coast mean licking ice cream cones and strolling on the promenade here, that’s a terrible mistake.”Corcoran is an education and outreach specialist with Oregon State University’s Oregon Sea Grant program. He works with coastal communities on tsunami preparation.

With the media attention from Saturday’s massive earthquake in Chile and the tsunami that it spawned sure to attract gawkers to the coast, Corcoran figured it would be a “teachable moment.”The National Weather Service issued an advisory that covered the West Coast indicating a tsunami capable of producing strong currents or waves was expected. It was canceled by early evening, and amid typical swells of around 8 feet and a falling tide on Saturday afternoon, few effects from the tsunami were visible in Seaside or elsewhere in the Northwest.The western edge of the Cascadia subduction zone lies just off the Pacific Coast and runs from Mendocino, Calif., all the way up to Vancouver Island. The last major quake off the coast was 310 years ago, Corcoran said. They come every 330 years on average.Such a quake could easily send a 60- to 90-foot wall of water onto shore within half an hour, he said.

There was no danger of that on Saturday, but police and Coast Guard helicopters shooed people off the beach repeatedly. As soon as they were gone everyone went back on the sand, Corcoran said.He urged people to learn the difference between the distant tsunamis and the close-up ones – “We’re going to be Chile, not Hawaii,” he said – and plan in advance a spot on high ground to meet with loved ones if a big wave does come.”When the earth shakes it’s too late to be looking for your map,” he said

collapsed buildingJAPAN was warned of the possibility of 10ft waves early today as a tsunami swept across the Pacific after the huge earthquake that struck Chile early yesterday. The first 12ft tsunami waves generated by the earthquake hit French Polynesia and the Chatham Islands in New Zealand. On an island off Chile the high waves swamped a village with five people dying and 11 missing but elsewhere there were no reports of damage though authorities warned that higher tides could come later. Waves of up to 6ft hit Hawaii at about midday local time, washing over a low-lying park near the city of Hilo.In Chile itself, hours after the pulverising shock of the magnitude 8.8 earthquake, rippled across the southern Andes, ministers in Santiago, the Chilean capital, said they did not expect the toll to rise much above the official toll of 214.

It seemed that a combination of strict building regulations in Chile and tsunami alarms throughout much of the region had averted what President Michelle Bachelet had initially called a “catastrophe”. The worst damage was inflicted on Concepcion, Chile’s second-largest city and the closest to the quake’s epicentre 70 miles out to sea. First reports described screams and cries from the ruins of a 15-storey building.

Alejandra Gouet, a television reporter in Concepcion, said: “There isn’t a street without damage.” Other reports spoke of buildings on fire across the city. The death toll, however, rose more slowly than had been expected at the outset. In the capital of Santiago, 200 miles from the epicentre, Bachelet warned that “we undoubtedly can’t rule out more deaths and injuries” but emphasised: “The system is functioning.” Huge waves pounded Chile’s Juan Fernandez archipelago, which includes the island where Alexander Selkirk, the Scottish sailor, was marooned in the 18th century, inspiring the novel Robinson Crusoe. Chile’s Easter Island, a world heritage site famed for its monumental Polynesian statues, was among the areas deemed most at risk. Tsunami warnings were issued to at least 59 nations and Pacific territories.

Charles McCreery, director of the Pacific Tsunami Warning Centre, said waves reaching Hawaii could be the largest to hit the islands since 1964. People had left the coast and petrol stations were jammed. On Tahiti traffic was banned from going within 500 yards of the sea. Central Chile was severely affected by the earthquake, which struck at 3.34am and was followed by violent aftershocks. Much of the country lost power, water supplies and communications. It was one of the most powerful tremors recorded in a region plagued for centuries by seismic upheaval. Concepcion was destroyed by earthquakes or tsunamis five times between 1570 and 1751, when the city was moved to a different location on the Bio-Bio river. It was destroyed again in 1835.

Charlotte Mountford, a Briton living in Santiago, said the tremor lasted about 30 seconds. “We crouched in bathtub on 14th floor while things smashed around us,” she wrote on the Twitter networking site. “Was terrifying.” John Grace, a British mining consultant, 54, said: “I have lived in Santiago 15 years and never felt anything like this earthquake before. It was by far the worst. I have a TV attached to the wall in my bedroom and it just collapsed.”

Claire Cunningham, 29, an IT consultant from Bromley, south London, added: “I am in Santiago on holiday with my husband, Tom. Our hotel room just rattled and rattled for a good minute. I thought the ceiling was about to cave in. It was horrifying. “We went down to the street and discovered that a TV mast had collapsed. There was concrete everywhere. If I had been under that at the time, I am sure I would have been killed.” The earthquake damaged 1.5m houses in Chile, one third of them seriously. Cars overturned, roads were split by fissures and the country suffered more than 100 aftershocks many of them stronger than five on the Richter scale.

On May 22, 1960, southern Chile was hit by the most powerful earthquake recorded, at a magnitude of 9.5. At least 1,600 people died. As a result, almost every large building constructed in Chile can withstand tremors. Yesterday’s earthquake was much more powerful than the 7.0 tremor that killed an estimated 230,000 people in Haiti in January, but the wealth Chile derives from being the world’s third-largest copper producer proved a significant barrier against mass destruction. “Chile is not Haiti,” noted one reporter. “The building codes are quite strict.”

Papeete  Tsunami waves that reached 6 feet (2 meters) French Polynesia finally crashed early Sunday morning. However, no immediate damage was reported.Polynesian inhabitants had been warned on Sunday morning local time that the tsunami may consist of several waves, and they must remain vigilant. This tsunami is the result of an earthquake measuring 8.8 Richter scale which menggunang Chile, Saturday morning.

In the City of Tahiti, the traffic is less than 500 meters from the beach is blocked. Residents who live in the lowlands were asked to go to a higher place.Mayor Rikitea Monique Richeton, as released Yahoonews say, the first tsunami wave height is less than 1 meter sweep Gambier Sunday morning and no damage was reported.
