Landslides can also be triggered by human action, the most common being building on unstable slopes. Submarine landslides, or massive slides and rock falls hitting the sea can also cause tsunamis.</p> <p class="undefined ">Landslides can reach speeds of over 50 km/h and can bury, crush or carry away people, objects and buildings.
