Recent landslide phases in the Czech Carpathians: identification, triggers and impacts

Popis výsledku v původním jazyce

Abundant research on landsliding exists at the present time. We focused on a somewhat omitted part of landslide research – landslide phases – events during which an increased number of individual landslides have been concurrently activated (Špůrek, 1967; Bíl et al., 2014). Landslide phases are important because their occurrence indicates the presence of a triggering event which predominantly involves, in the area of the Carpathians, high rainfall or snow thaw. Whereas the newest landslide phases (1997, 2006 and 2010) have been sufficiently evidenced (Krejčí et al., 2002; Bíl and Muller, 2008; Pánek et al., 2011), the older ones have not as yet been investigated enough. Identification of those older landslide phases can be accomplished using archive sources, including chronicles of the affected villages and towns or aerial photographs. Each data source has its own specific drawbacks which will be addressed. Chroniclers had occasionally a different view of the importance of natural processes. Extreme rainfall and even hailstone events have been evidenced irregularly often based on the personality of the chronicler and therefore a distinct change in weather at municipality borders has been recorded. We also interviewed eyewitnesses and persons directly affected by landsliding. Aerial photographs were only of limited use as they were predominantly taken during growing seasons. Landslide triggers can only be computed from existing precipitation data sets. This limits the extent of our study to the past as the oldest accessible data in this area come from the end of the 19th century. The reverse approach is also possible, however. Triggering rainfall in all probability occurred when a number of landslides were identified in the historical records. We have previously identified 6 distinct landslide phases in the central part of the Czech Carpathians (Bíl et al., 2014).
