石渠5．1级地震与德格5．0级地震灾害对比

本文根据现场调查资料描述了四川省相邻的两县石渠县和德格县分别发生的Ｍｓ５．１和５．０级地震的灾害情况，并对这两次地震的灾害特征和灾害环境等作了对比。虽然这两次地震的震级相近，宏观震中仅相距约１３０ｋｍ（直线距离），但地震所造成的经济损失和社会影响却相差较大。导致这种灾害明显差异的原因主要是先前的冻胀灾害和自然地理环境以及建筑物场地条件的不同。     

潜水含水层井损计算方法探讨

本文根据潜水含水层稳定流多落程抽水试验所取得的△hw2～f（Q）关系曲线，推导出了潜水含水层中井损计算公式或并结合实例阐述了潜水含水层中稳定流抽水试验井损的计算方法；对利用稳定流抽水试验准确求解水文地质参数具有一定参考意义。     

东亚寒潮高压的位涡诊断研究

用位势涡度方程对1980年1月26—30日东亚寒潮高压的演变做了诊断研究，表明高压中心地区低层是低值位涡区，位涡值随高压增强（减弱）而变小（变大）；随着高压的发展加强，位涡最小值由对流层中层降到近地面层，随着高压的减弱，最小值中心又上升；对流层高层的位涡值随着地面高压的增强而加大，反映高空冷槽、地面高压同时在发展。位涡收支方程各项对高压发展、减弱有着不同的作用。作用最大的是地转风水平平流项和地转偏差风的散度项，其次是地转偏差风的平流项和辐射项，扭转项和热成风偏差项均甚小，可忽略不计。     

Fire and cyclone damage to woody vegetation on the north coast of the Northern Territory,Australia

Tree stem (>2 m tall) mortality was assessed following a late dry‐season wildfire across a seasonally flooded elevation gradient at Workshop Jungle, near Darwin, in the Northern Territory of Australia. For all species combined, dead stems had significantly smaller diameter at breast height (dbh) than living stems. Assessment of tree‐stem damage following a tropical cyclone at Cobourg Peninsula, NT, revealed that damaged stems had significantly greater dbh than undamaged stems for all tree species sampled across a boundary between monsoon rainforest and savanna. A greater proportion of stems were damaged by the cyclone than by the fire (28 per cent as against 18 per cent), although there were considerable between‐community differences in the proportion of damaged stems at the two sites. The fire caused little impact (<10 per cent) on total basal area of three different forest communities on the elevation gradient at Workshop Jungle. The cyclone was found to cause >50 per cent damage to total basal area of three different communities on Cobourg Peninsula. It is suggested that the combination of a cyclone followed by an intense fire in storm debris could potentially destroy a monsoon rainforest through its impact on all tree‐size classes. This may explain why some monsoon rainforests rapidly contracted following Cyclone Tracy that destroyed the city of Darwin on Christmas Day, 1974.

1993年沐川5.0级地震预测及其震灾评估

１９９３年８月７日沐川凤村５．０级地震前，省、市地震部门曾提出过中短期预测意见。事实表明所作判断在一定程度上是准确的。震后进行了现场考查及震害评估。其震中烈度为Ⅶ度，震中区呈近东西向椭圆形。地震造成３人受伤，总经济损失达１０８２．２万元。     

Field survey of the East Java earthquake and tsunami of June 3, 1994

A field survey of the June 3, 1994 East Java earthquake tsunami was conducted within three weeks, and the distributions of the seismic intensities, tsunami heights, and human and house damages were surveyed. The seismic intensities on the south coasts of Java and Bali Islands were small for an earthquake with magnitudeM 7.6. The earthquake caused no land damage. About 40 minutes after the main shock, a huge tsunami attacked the coasts, several villages in East Java Province were damaged severely, and 223 persons perished. At Pancer Village about 70 percent of the houses were swept away and 121 persons were killed by the tsunami. The relationship between tsunami heights and distances from the source shows that the Hatori's tsunami magnitude wasm=3, which seems to be larger for the earthquake magnitude. But we should not consider this an extraordinary event because it was pointed out byHatori (1994) that the magnitudes of tsunamis in the Indonesia-Philippine region generally exceed 1–2 grade larger than those of other regions.
