Evaluation and implication of researches on prediction of earthquakes and volcano eruptions

根据大地测量理事会的“关于推进新的国家地震观测研究计划”和“关于推进第六次国家火山爆发计划”的建议，对地震和火山爆发预测研究的成果进行了总结，并汇总了新的成果，以研究地震预测研究的趋势。我们在2002年和2003年举行了地震预测研究年度报告会议，有100多人参加。我们讨论了2004年以来的下一个地震预测研究计划。我们讨论和评估了火山喷发研究的最新趋势和结果。我们还检查了Mt。富士山地震对社会活动的影响很大，近年来地震发生频率较低。我们调查了第七次全国火山喷发预测计划。

We summarized results of the research on prediction of earthquakes and volcanic eruptions, which are conducted under the recommendations titled as "On the Promotion of the new National Program of Observational Study for Earthquake Prediction" and "On the Promotion of the Sixth National Program for Volcanic Eruption" by the Geodesy Council.We have compiled new results to study the trend of studies of earthquake prediction studies. We held meetings for the annual report of earthquake prediction research studies in 2002 and 2003, which more than 100 people attended. We discussed plans for the next earthquake prediction research program since 2004.We have discussed and evaluated the recent trends and results of the volcanic eruption studies. We examined also Mt. Fuji, under which low frequency earthquakes occurred recently because of its strong impact on the social activities. We investigated the seventh National Program for Prediction of Volcanic Eruption.
