valanga Anglais:

An avalanche can be extremely dangerous for climbers.

Eight climbers were trapped by last night's avalanche.

In the Russian mountains, two brothers try to rescue the survivors of an avalanche from under the snow.

Without it, you will experience yet more avalanches, and this time they will hit populated areas.

I've seen three avalanches already.

You musn't shout in the mountains, because you may cause an avalanche.

As soon as you contact your friends, tell them that an avalanche is coming.
