Recent geological activity along the northeastern Bulgarian Black Sea coast

摘要: The densely populated northeastern Bulgarian Black Sea coast is a territory of intensive contemporary development. It is, though, marked by considerable recent geological activity along the coastal zone comprising: faulting, earthquakes, landslides, carthflows, rockfalls, ground subsidence, marine erosion and variations sea level. These are locally exacerbated ongoing development, resulting in increased instability. Notably, part coastline has been lost as result gravity sliding. Analysis this activity, including carthflows rockfalls 1996-1997, needs be taken into account for protection population cultural heritage.
