Chance of big earthquake in next few days
The earthquake swarm hitting canton Valais is continuing.
Several more tremors have shaken the canton – with one at 3.5 on the Richter Scale yesterday evening.
More than 140 small quakes have been registered since Tuesday morning. Seismologists say it’s very unusual. There hasn’t been a similar case for 20 years.
While experts say predicting earthquakes is extremely hard, they estimate there is a small chance of a far bigger quake in the next few days.
