4. 3. NATURAL DISASTERS Three main causes: Cosmic (a meteorite fall) Geologic Climatic

5. NATURAL DISASTERS EARTHGUAKES: Its origin is on boundaries of lithospheric plates It is a consequence of collision, sliding and subduction It causes quakes of the continental crust Tsunami Earthquakes under the sea level, very fast spreading waves

6. NATURAL DISASTERS VOLCANIC ERUPTION: It accompanies earthquake zones Lava stream Ash clouds Lightning and storms are caused by friction of volcanic ash dispersed in the atmosphere A rainstorm causes mud streams = fast moving flood waves of mud

7. NATURAL DISASTERS LANDSLIDES: After long-term rains and during spring melting Slushy masses of rocks slide into valleys and destroy roads and settlements In the CR landslides appear in the Beskydy Mountains and in the Elbe Valley In the mountains there are snow and rock avalanches

8. NATURAL DISASTERS FLOODS: In Europe during spring melting and after heavy rains 100-year flood = rivers are lifted up to 6 m above their level
