The 1994 Shikotan earthquake tsunamis   总被引：1，自引：0，他引：1

The 1994 Shikotan earthquake was one of the greatest earthquakes in recent years with a magnitude ofM _s 8.0. A tsunami survey was conducted by Russian and U.S. geophysicists from October 16–30, 1994, less than two weeks after the earthquake. The survey results and a numerical hindcast simulation are reported. Tsunami focusing effect at locations supposedly sheltered by the island chain is discussed. Based on the obtained data, tsunamis which attacked Shikotan Island are characterized as long waves (the order of 10–20 min wave period) with a positive leading wave. Possible consequences of the positive leading wave form are discussed in relation to the observed minimal destruction of beach vegetation and relatively small transport of marine sediment onto the shore. The high-quality tide-gage record in Malokurilskaya Bay indicates the occurrence of a 53 cm subsidence at the site.  相似文献   

等结构矿物的光性异向指数          下载免费PDF全文

叶大年 《地质科学》1985,(1):59-69

在研究透明矿物光学异向性时,人们总是用三个主折射率 N_g、N_m、N_p 和重折射率N_g-N_p 来表示。本文作者在一系列的论文中使用了折射度指示体和光性异向指数的新概念。用光性异向指数(Optical anisotropy index 即 OAl 值)研究矿物光学异向性与晶体结构关系时,远远比折射率和重折射率的概念更有意义得多。  相似文献   

Variations of radon content in groundwaters and possible correlation with seismic activities in northern Taiwan     

K. -K. Liu  T. -F. Yui  Y. -H. Yeh  Y. -B. Tsai  T. -L. Teng 《Pure and Applied Geophysics》1984,122(2-4):231-244

Radon (²²²Rn) concentration in geothermal waters and CO₂-rich cold springwaters collected weekly in duplicate samples from four stations in northern Taiwan were measured from July 1980 to December 1983. Seven spike-like radon anomalies (increases of 2 to 3 times the standard deviation above the mean) were observed at three stations. Following every anomaly except one, an earthquake ofM _L above 4.6 occurred within 4 to 51 days, at an epicentral distance 14 to 45 km, and at a focal depth of less than 10 km. The distribution of the earthquakes preceded by radon anomalies is skewed in certain directions from the radon stations; the radon stations seem to be insensitive to earthquakes occurring in the other directions. At the fourth station, near a volcanic area, much gas (mainly CO₂) is discharged from the well, together with hot water. A very high concentration of radon was detected in the discharged gas; therefore trapping of gas in the water can result in anomalously high radon contents. According to limited measurements, the radon concentration in water appears to be undersaturated with respect to that in gas. This suggests that hot water is very susceptible to radon loss, and monitoring of radon in gas is more desirable.  相似文献

东亚和太平洋地区上空的平均垂直环流----(二)冬季   总被引：1，自引：1，他引：1  

杨广基  王兴东  叶笃正 《大气科学》1979,3(4):299-305

本文继《东亚和太平洋地区上空的平均垂直环流(一)夏季》之后,分析了该地区冬季平均垂直环流的特点,得出以下主要结果: 冬季南亚季风区的经向环流为强大的Hadley环流所控制,这一环流在青藏高原南侧发展得最为强盛,出了高原向东其强度逐渐减弱;在中、东太平洋的中纬度逆环流成为主要环流系统,Hadley环流远弱于夏季,只存在于赤道低纬度的低空。 本文对该地区的纬向垂直环流也进行了讨论。  相似文献

Rare earth elements in Silurian pelitic schists from N.W. Maine     

Robert L Cullers  Long-Tsu Yeh  Sambhudas Chaudhuri  Charles V Guidotti 《Geochimica et cosmochimica acta》1974,38(3):389-400

Thirty-two samples of a series of metamorphosed Silurian (?) pelitic schists in the greenschist and amphibolite facies from N.W. Maine have been analyzed for their rare-earth element (REE) content. The REE contents of these samples do not change as a function of metamorphic grade. Two different metasedimentary formations have been sampled, and they differ significantly in their light REE content. The absolute and relative distribution of the REE in the Bangeley Formation are quite similar to the composites of N. American, European and Russian shales that have been determined thus far (e.g. median La/Lu ratio of the Bangeley Formation normalized to chondrites = 8.7 ± 3.0). Samples from the Perry Mt. Formation show large depletions in the light REE compared to the Bangeley Formation and previously analyzed shale and metamorphosed shale samples, but heavy REE concentrations that are quite similar to the other samples (e.g. median La/Lu ratio of the Perry Mt. normalized to chondrites = 1.2 ± 0.6). These differences in light REE content between the Perry Mt. Formation and other sedimentary rocks are probably due to differences in the original clay mineral compositions as modified by weathering and/or depositional environments.  相似文献
