Large and small earthquakes occur frequently in Peru. Official institutions in charge of the study of seismological and geophysical aspects of such large natural events have a responsibility to provide engineers, planners, and government officials with basic data to implement safety measures to minimize the destructive impact of great earthquakes. The Geophysical Institute of Peru (IGP) is one such institution.
\nThe interest of the scientific community in earthquake studies has been high in Peru for a long period of time. In contrast, the negineering and social aspects of earthquakes have been studied only for the past decade.
\nIn retrospect, the Peruvian national long-range earthquake-study program began after the catastrophic earthquake of May 31, 1970. This earthquake triggered a large snow avalanche from Huascaran mountain, killing over 60,000 people, and covering with mud small cities and tens of villages in the Andean valley of Callejon de Huaylas, Huaraz. Since then, great efforts have been made to learn about the natural seismic environment and its engineering and social aspects. The Organization of American States (OAS)has been one of the most important agencies in the development of the program.

Correspondingly, needs for information to use in management have increased. Inadequate information leads the manager to err on the conservative side; unless the size of the 'harvestable surplus' is known, the population cannot be fully exploited. Conversely, information beyond what is needed becomes an unaffordable luxury. Population modeling has proven useful for organizing information on numerous game animals. Modeling serves to determine if information of the right kind and proper amount is being gathered; systematizes data collection, data interpretation, and decision making; and permits more effective management and better utilization of game populations. This report briefly reviews the principles of population modeling, describes what has been learned from previous modeling efforts on furbearers, and outlines the potential role of population modeling in furbearer management.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Midwest Furbearer Management.

The comparisons at four dates showed that two vegetation index models, TV16 and GVI, are highly correlated (P = 0.01) with green yield, green cover, and plant moisture content. The green vegetation index (GVZ) developed by Kauth and Thomas (1976), was highly correlated and superior to other models in relationship to wet green yield, dry green yield, and cured vegetation cover. TV16, developed by Rouse et al. (1974), was more highly correlated with green vegetation cover and vegetation moisture content. Both TV16 and GVI are superior to other models in their relationship with green cover. None of the Landsat MSS parameters tested was significantly correlated with dry total yield, percent bare ground, or moisture of the soil measured at the surface or at a 20 cm depth. I t is concluded that Landsat MSS data are sensitive to seasonal changes in vegetation growth conditions and inherent ecological differences within a relatively unqorm vegetationlsoil system.

The sampler can be used from a manned research submersible or by a diver in shallow water. In areas of active deposition, the material collected represents the most recently deposited sediment. This material is of interest for determining the concentration of anthropogenic contaminants at the sea floor and may be a much more sensitive indicator of early contamination than are bulk samples collected by means of conventional grab samplers or corers. The instrument also may be well suited for sampling freshly flocculated or precipitated material from the sea floor, for example in estuaries or around thermal vents on mid ocean ridges.

Salt domes along the trough's seaward side show evidence of active diapirism and a normal growth fault along its landward side has been continually active at least since the end of the Jurassic. This steep fault extends to a strong reflection event at about 11 km depth that may represent the top of a salt layer. We infer that faulting is caused by seaward flow of salt from the deep part of the trough into domes, thereby removing support for the overlying block of sedimentary rock. Diapirs off eastern North America seem to be concentrated in the Carolina Trough and Scotian Basin, where basement seems to be thinner than in other basins off eastern North America, south of Newfo ndland. Thinner basement, probably due to greater stretching during rifing, may have resulted in earlier subsidence below sea level, a longer life for the salt evaporating pans in these basins, and thus a thicker salt layer, which would be more conducive to diapirism.

Necropsy showed acute bloat and chronic liver disease. In samples of liver tissue fixed in 10% neutral buffered formalin, approximately 25% of the total volume of tissue was comprised of multiple white to cream-colored circumscribed nodules up to 1 cm in diameter, which were gritty when cut (fig. 1).
Samples of liver were cut at 6 μm for histologic examination. Microscopically, the nodules consisted of aggregations of large, vacuolated cells resembling fat cells with spicules of mature bone scattered throughout many nodules (fig. 2). Most nodules were circumscribed but not encapsulated. Single or small clusters of vacuolated cells, however, were scattered diffusely in the hepatic parenchyma surrounding the nodules. We found cholangitis and peribiliary fibrosis in some areas, but no generalized cirrhosis. Degeneration of hepatocytes was seen in some areas peripheral to the nodules. Compression of the hepatic architecture was evident in the liver parenchyma surrounding some nodules, but the primary change was infiltrative rather than expansive. Foci of lymphocytes and a few neutrophils were present in some nodules. Hematopoietic cells, described as a characteristic of myelolipomas, were not found in any of the nodules examined [2, 4].

The study area contains three provinces: (1) a nearshore province (shallower than 18 m) with a relatively steep slope (0.6°) and a cover of medium sand; (2) a northern offshore province covered with coarse sand, gravel, and boulders, interpreted to be glacial drift; and (3) a southern offshore province with a gentle seaward-dipping slope (0.3°) and a surface sediment of coarse sand. The glacial drift exposed in the northern offshore province can be traced southward under the coarse sand province. The overlying fill is comprised of either outwash sediment derived from the Pleistocene South Channel ice lobe to the east or Holocene-aged marine sediments eroded from seacliffs to the north. Latest Holocene sediment appears to be limited to the zone shoreward of 18 m where the medium sand occurs.
Near-bottom mean flows (measured over two winter months in 10 m water depth) average 6 cm sec−1 to the south. Mean flows exceeded 20 cm sec−1approx. 23% of the time. Ninety percent of the flows exceeding 20 cm sec−1were directed to the south, reflecting the dominant atmospheric forcing during these winter months. Waves had an average variance of 650 cm2 with variance exceeding 5000 cm2, 3% of the time, indicating moderate wave activity.
Present processes are actively reshaping the nearshore province, which is characterized by many east to northeast-trending shore-oblique channels that do not extend seaward of the 18-m contour. Coarse sand in the floors of these channels suggests they may be erosional features, and the presence of megaripples oriented perpendicular to the channel axes indicates active transport in these channels.

The nodules were prepared in three digestion matrices. One of these solutions was measured using sixteen different combinations of burner height and air/acetylene ratios. Results for A-1 and P-1 are compared to recommended values and results for all nodules are compared to those obtained with an inductively coupled plasma. The elements Co, Cu, Fe, K, Mg, Mn, Na, Ni, and Zn are simultaneously determined with a composite recovery for all elements of 100 ± 7%, independent of the digestion matrices, heights in the flame, or flame stoichiometries examined. Individual recoveries for Co, K, and Ni are considerably poorer in two digests than this composite figure, however. The optimum individual recoveries of 100 ± 5% and imprecisions of 1–4%, except for zinc, are obtained when Co, K, Mn, Na and Ni are determined simultaneously in a concentrated digest, and in another analytical sequence, when Cu, Fe, Mg, Mn and Zn are measured simultaneously after dilution. Determination of manganese is equally accurate in the two sequences; its measurement in both assures internal consistency between the two measurement sequences. This approach improves analytical efficiency over that for conventional atomic absorption methods, while minimizing loss of accuracy or precision for individual elements.

Systematic research is done at the university of Chile in Santiago. Other universities such as the Catholic University, university of Concepcion, and the Federico Santa Maria Technical University have begun to teach and conduct research in earthquake engineering in recent years.
\nThe fields of research at the University of Chile include the following:
\nPassage Creek, in northwestern Virginia, flows on relatively nonresistant shales, then cuts through a gorge underlain by resistant sandstone In the gorge, the stream gradient steepens, the size of bed material increases, a braided channel forms, and riparian-forest composition and growth form changes relative to areas outside the gorge Effects of flooding are intensified within the gorge and revealed in the pattern and deformation of streamside vegetation Increased stream gradient within the gorge provides for high stream power and coarse sediment deposition relative to the flood plain outside the gorge. A more diverse upland forest grows on the flood plain in the gorge The riparian forest in the gorge may be an example of a nonequilibrium forest, resulting from periodic disturbance by destructive floods. Recognition of vegetation patterns resulting from such disturbances may be useful in detection of potential flooding.

Combined wind-driven and tidal currents exceeding 30 cm/s at 1 m above the bottom and intense oscillatory bottom currents with maxima above 45 cm/s were associated with the largest measured values of TSM at 2 m above the sea floor. The values of u* and z0 obtained from the ‘law of the wall’ velocity-depth relationship are diminished substantially throughout the storm period (average reduction of 44%) when the turbulence reducing effects of the vertical concentration gradient of TSM are considered. The form of the latter correction was adapted from Smith and McLean (1977a). Values of the mean u* computed from the theory of Grant and Madsen (1979), which predicts an enhanced shear stress due to nonlinear wave-current interactions, compare favorably with the u* values determined from the measured velocity profiles. The measured values of z0, however, are considerably larger than any of the estimates based on (1) the actual scales of the physical roughness elements; (2) the apparent roughness of Grant and Madsen (1979); or (3) the thickness of the bed-load layer as formulated by Smith and McLean (1977a).

Trials with different Bouguer reduction densities indicate that this positive anomaly cannot be explained by an inappropriate choice of Bouguer reduction density but must be caused by a subvolcanic body. After separating the Medicine Lake gravity high from the regional field, we were able to fit the 27-mgal positive residual anomaly with a large, shallow body of high density contrast (+0.41 g/cm3) and a thickness of 2.5 km. We interpret this body to be an intrusion of dense material emplaced within the several-kilometres-thick older volcanic layer that probably underlies Medicine Lake volcano.
