TL;DR: In this paper, a spatio-temporal distribution of deadly landslides is presented for 27 European countries over the last 20 years (1995-2014) and a total of 1370 deaths and 784 injuries were reported resulting from 476 landslides.

TL;DR: In this paper, three spatial extensometers were installed here in carefully selected sites to reflect fault movements on fissures, enabling three-dimensional detecting of even very slow movements with the accuracy of 0.01mm and high stability over time.

TL;DR: In this paper, the authors showed that displacement trends changed significantly at several points in the period from 1997 through 2000; afterward, long-term trends were restored This phenomenon took place in the periods of strong (M > 7) earthquakes in Iran (1997) and in the North Anatolian fault zone in Turkey (1999) Two strong Izmit earthquakes of 1999 in Turkey at distances of 600 km from the Balkan Peninsula and 1400 km from observation points in Central Europe were the main seismic events of the period studied.

TL;DR: In this paper, the authors describe a case in which relatively inexpensive monitoring has been successful in terms of interpretation of results, and describe the case of a bas-relief on a high rock face in a seismically active area in NE Bulgaria.

TL;DR: The analysis of the structures of the landslides along the Northern Bulgarian Black Sea coast gives the reason to consider the earthquakes as one of the main factors that activate their creation and their periodical reactivation as mentioned in this paper.
