SAN FRANCISCO, March 30 (Xinhua) -- History records showed it was not often that large earthquakes caused immediate large volcano eruptions, a geophysicist told Xinhua on Wednesday while talking about whether the recent massive quake in Japan could trigger volcano eruptions.Inevitably, the shaking and changes in the state of stress in the crust could cause some changes in some of active volcanoes closest to the March 11 quake zone in Japan, said Dr. Jian Lin, senior scientist and geophysicist at the Woods Hole Oceanographic Institution in the United States.However, only if a particular volcano was already in a stage of magmatic inflation, a situation close to eruption, would the shaking make a major difference, he noted.Lin is currently visiting the U.S. Geological Survey's earthquake research center in Menlo Park, California to study the March 11 Japan earthquake.Compared with the cases that earthquake triggered volcano eruptions in the past, Lin said, most of active volcanoes in Japan are located somewhat farther away from the March 11 earthquake rupture zones. "The farther away, the less direct effect," he noted.Therefore, "the most important thing is to closely monitor all the active volcanoes in Japan," he said.There are only two well-documented cases of significant volcano eruptions that were apparently triggered by large earthquakes, he said.On Nov. 29, 1975, the Kilauea Volcano in the Hawaiian Islands had a small and short-lived eruption immediately after a magnitude- 7.2 quake hit the Big Island of Hawaii near the volcano, which was probably the best scientifically documented case so far of a volcano eruption triggered by a large earthquake.Records showed that the Kilauea Volvano was already in a stage of inflation before the quake. Meanwhile, the quake was right next to the volcano, which triggered the following eruption.Another case is 1960 Chile earthquake-volcano pair, in which a magnitude-9.5 earthquake, the largest ever recorded by instruments, could have triggered the Puyehue-Cordon Caulle Volcanic Complex ( PCCVC) into a violent eruption within 38 hours. The CCVC had been inactive for 25 years before the quake.Lin pointed out that like the Kilauea case, the earthquake rupture zone in the Chilean quake was again quite close to the volcanic group. However, little scientific monitoring data had been got for the PCCVC before its eruption as it is in a remote area in Chile.In recent years, scientists have observed that large earthquakes from long distance could trigger swarms of small earthquakes in active hydrothermal systems of volcanic regions, he said, noting that "these small earthquake swarms like these are not the same as volcano eruption."Lin added that the relationship between large volcano eruption and large earthquakes is still a poorly studied subject since scientific record is very short and many of large eruptions in the geological history were poorly documented."Therefore, we still know quite little about this subject," he said.

WASHINGTON, May 1 (Xinhua) -- The launch of U.S. space shuttle Endeavour on its final voyage will be no earlier than May 8, after technical problems uncovered last week proved more complex than originally thought, the U.S. National Aeronautics and Space Administration (NASA) announced Sunday.NASA tried to launch Endeavour on Friday on its 25th and final flight to deliver the 2-billion-dollar Alpha Magnetic Spectrometer (AMS) particle detector to the International Space Station. AMS, a particle physics detector, is designed to search for various types of unusual matter by measuring cosmic rays. Its experiments are designed to help researchers study the formation of the universe and search for evidence of dark matter, strange matter and antimatter.The space shuttle Endeavour sits on launch pad 39A as work continues on the shuttle's auxilliary power unit at the Kennedy Space Center in Cape Canaveral, Florida May 1, 2011.However, the launch was called off after engineers detected a failure in one of two heater circuits associated with Auxiliary Power Unit (APU) 1. Heaters are required to keep the APUs' hydrazine from freezing on orbit.NASA hoped Endeavour would lift off on Monday. But further trouble-shooting indicated the glitch was more complicated than officials hoped initially.The failure appears to be a power problem within the aft load control assembly-2, a box of switches controlling power feeds."That basically means the power is not getting out to the heaters that weren't working on launch day," said Space Shuttle Program Launch Integration Manager Mike Moses.

SAN FRANCISCO, May 26 (Xinhua) -- Internet advertising revenues in the United States surged to 7.3 billion U.S. dollars in the first quarter of 2011, the highest first-quarter revenue level on record for the industry, said a new report released on Thursday.The numbers also represented a 23-percent increase over the same period a year earlier, the Interactive Advertising Bureau ( IAB) and PricewaterhouseCoopers said in the report."The consistent and considerable year-over-year growth we're seeing demonstrates that digital media is an increasingly popular destination for ad dollars, and for good reason," Randall Rothenberg, chief executive officer of the IAB, said in a statement."As Americans spend more time online for information and entertainment purposes, digital advertising and marketing has emerged as one of the most effective tools businesses have to attract and retain customers," he added."These numbers indicate that the interactive advertising field hasn't simply bounced back since the recession; it's growing with dynamic energy," noted David Silverman, a partner at PricewaterhouseCoopers.IAB, a trade association for interactive marketing, comprised more than 500 media and technology companies who are responsible for selling 86 percent of online advertising in the United States.

BEIJING, Jan. 30 (Xinhua) -- As of Jan. 28, 77.4 million mu (5.16 million acres) of crops had been harmed by the ongoing drought, and 2.57 million people were faced with drinking water shortages in China, the national drought control authorities said Sunday.Local governments of the affected regions must make efforts to monitor drought conditions, speed up the building of water projects, increase drought-fighting material reserves and grant subsidies to the drought-stricken population, said officials at a meeting attended by Chen Lei, deputy head of the Office of State Flood Control and Drought Relief Headquarters (SFDH).The National Meteorological Center (NMC) forecast the drought to worsen in the next two months, saying Sunday that the drought-hit north China and regions along the Yellow and Huaihe rivers would receive little rain or snow in February and March.Chen, also minister of water resources, stressed the importance of drought relief efforts, guaranteeing agricultural production and ensuring drinking water safety for boosting consumers' confidence, controlling consumer prices and inflation and maintaining economic growth.Since last Autumn when the drought began, local authorities have assigned 9.55 million people and 2.15 million sets of drought-fighting machineries to draw 8.2 billion cubic meters of water to irrigate 110 million mu of crop land.

HEFEI, Feb. 2 (Xinhua) -- Chinese Premier Wen Jiabao has visited farmers and workers in Dabieshan Mountain area, an old revolutionary base in east China's Anhui Province, to extend new year greetings ahead of the Spring Festival, which falls on Thursday.On Tuesday, Wen went to the area's Jinzhai County, once an important Red Army revolutionary base, to learn about the local economic and social development situation.He visited Zhaoyuan Village and called in on farmer Zhao Mengqi. Wen chatted with Zhao, asking about his family's income and their preparations for the lunar new year.Zhao works as a migrant worker in Wujiang City, an economically-developed part of Jiangsu Province. His son and daughter-in-law work in Shanghai. They returned home on the eve of the Spring Festival."With the income we earn working in cities and what we earn growing crops, our family income has increased and we have rebuilt and renovated our house," Zhao told Premier Wen. A paved road now allows buses to reach the village, Zhao added.Wen said, "Only when the people living in old revolutionary bases live better lives can we feel relieved."At farmer Zhao Kongying's home, Wen joined the family in making "yuanzi," a glutinous rice ball traditionally eaten during the Spring Festival.Wen later went to Hetang Village. There he visited villager Yu Shuhua's home and urged the local government to provide more help to needy people to ensure they have a happy lunar new year.At dinner time, he went to villager Zhang Jiasheng's home, joining the family to prepare dinner. He wore an apron and made a soup for the family.During the dinner, Zhang told Wen the village is rich with chestnuts, tea and traditional Chinese medicine, adding that tourism is also a source of income for the village.Wen said help and support for the old revolutionary base should be boosted, so that local people can lead happier lives.Wen also extended new year greetings to workers at the Meishan hydropower station in Jinzhai County.At retired worker Wan Benrong's home, Wen asked about the family's living conditions and their preparations for the lunar new year.After being told the couple received an extra 140 yuan each of monthly pension this year, Wen said the government has increased the basic pension for retired workers seven times since 2005."Our objective is to make you feel secure," Wen said.
