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.

BEIJING, Feb. 1 (Xinhua) -- Two Air China passenger planes carrying 457 Chinese citizens stranded in Egypt are due to arrive in Beijing early morning on Wednesday.The planes took off from the Cairo International Airport respectively at 11:16 and 15:32 local time (0916 and 1332 GMT) on Tuesday.The Civil Aviation Administration of China (CAAC), the nation's aviation authority, said Tuesday it was doing its best to organize flights to Egypt to bring home Chinese tourists stranded in the North African nation.China has arranged six flights to fly stranded Chinese nationals home, the CAAC said in a statement posted on its website.

BEIJING, Feb. 23 (Xinhua) -- The Chinese People's Political Consultative Conference (CPPCC), China's top political advisory body, opened its door to 43 correspondents from 33 overseas media outlets on Wednesday, 10 days ahead of its upcoming annual session.It was the first time that the top political advisory body invited a group of overseas journalists, including those from Hong Kong, Macao and Taiwan, to tour its work place, which used to be the site of an imperial compound 100 years ago.The media tour was hailed by Zhao Qizheng, head of the CPPCC's Committee of Foreign Affairs, as a move that reflects the "enhanced openness" of the CPPCC.During the tour, resident reporters from countries and regions such as the United States, Russia, Germany and Japan visited the CPPCC auditorium and a gallery that exhibits the agency's history and its role in Chinese political life through numerous pictures and relics.Located in downtown Beijing, the CPPCC was established on September 21, 1949. It is a patriotic united front organization for Chinese people and serves as a key mechanism for multi-party cooperation and political consultation under the leadership of the Communist Party of China (CPC).The main functions of the CPPCC are to conduct political consultations, exercise democratic supervision and participate in the discussion and the handling of state affairs. Reporters raised many questions during the visit.Watanabe Yasuhito, a staff correspondent for the Kyodo News China General Bureau, has been working in China for four years. "As Japan doesn't have similar institutions like the CPPCC, the Japanese generally have little idea of it," he said. "I now have a more direct idea of the system by actually walking into the CPPCC."He told Xinhua that Kyodo News would send eight reporters to the upcoming two annual sessions of China's National People's Congress (NPC), its national legislature and the CPPCC, as many Japanese pay close attention to the major political events in China.He said the 12th Five-Year Program and hot economic issues are among their key concerns. At a one-hour seminar held during the tour, five reporters put forward nearly 10 questions to Zhao Qizheng.Ananth Krishnan, the China correspondent of the Hindu, India's national newspaper, has covered the "two sessions" several times. "I think the next five year plan will be one of the most important issues," he said."We will be interested to see whether there are any new policies in terms of China addressing environmental challenges," he said.He added that he focused on China's reform for the household registration system at the sessions last year so that he could see how China addressed the gap between urban and rural areas."There are similar developmental challenges between India and China since we are both large developing countries with more poverty in rural populations. So we are interested to see how China is addressing the challenges," he said.With the application still going on, overseas reporters who are to cover this year's annual CPPCC session are expected to exceed 1,100, similar to the figure last year, said Zhang Jing'an, head of the Bureau of News Service of the CPPCC's National Committee.Zhang said that besides the three news conferences in the Great Hall of People, five press conferences are devoted to issues such as China's urbanization, scientific innovation, culture and education. Conferences will also be arranged in the news center following annual sessions.Also, the number of panel discussions that were open to the media increased from more than 30 in 2007 to 122 in 2010, Zhang said.Zhao Qizheng told overseas reporters that "the CPPCC will continue to enhance openness during the upcoming session and welcome reporters from both here and abroad to cover the session."China's two annual sessions, the fourth session of the National Committee of the 11th CPPCC and the fourth session of the 11th NPC, will open on March 3 and March 5, respectively.

BEIJING, May 12 (Xinhuanet) -- Italian archaeologists are digging the remains of Lisa Gherardini, a 16th-century woman who is widely believed to be the model for the famous portrait Mona Lisa, AFP reported on Wednesday.The team of historians say they will try to find the remains using geo-radar equipment and then try to re-create a likeness of what the woman, Lisa Gherardini, would have looked like to compare her to Leonardo Da Vinci's Mona Lisa.Gherardini (1479-1542), also known by her married name as Lisa del Giocondo, was the wife of a Florentine silk merchant and is widely believed to have been the model for the  portrait that now hangs in the Louvre in Paris.But the issue has never been settled definitively and mystery still shrouds the model's enigmatic expression and other details of the portrait.
