The importance of earthquake-induced landslides to long-term slope erosion and slope-failure hazards in seimically active regions
This paper describes a general method for determining the amount of earthquake-induced landsliding that occurs in a seismically active region over time; this determination can be used as a quantitative measure of the long-term hazard from seimically
triggered landslides as well as measure of the importance of this process to regional slope-erosion rates and landscape evolution. Comparisons with other slope processes indicate that earthquake-induced landslides are the predominant agents of slope erosion

Since models of global warming predict that climatic changes will be greatest in the Arctic and might already be in progress, it is prudent to attempt to understand the rapidly changing thermal regime on Eurasian cold regions. In this paper
the A. tries to evaluate the probable catastrophic implications of global climatic change in the cold regions of Eurasia. The impact on Man activities in permafrost regions is discussed.
Studies of rockfalls and block slides provide insight about shaking hazards in alpine mountains subject to earthquakes. Large samples of the longest axis of the largest on each block can be used to identify regional landslide events; the coseismic
rockfall lichenometry model can be used to date and locate prehistorical earthquakes, document regional frequency of earthquakes, and describe regional patterns of seismic shaking. Determination of colonization time, great-growth phase, and especially
uniform phase rates of lichen growth are essential for dating regional landslide events.
