The Pizol Glacier is the first glacier in Switzerland to be declared dead in 2019 and it will not be the last if global warming continues to this extent. Because glaciers and permafrost are melting, our mountains are becoming more and more unstable. In the coming years it is expected that dangerous rockfalls will increase in size and quantity and that they will also occur in previously safe areas. At the same time, leisure activities such as hiking and mountain biking are becoming popular and more and more people are living in endangered places. In order to better anticipate the effects of these changes and to be able to warn people, it has become very important to understand the movements and activities of our mountains. Despite recent efforts in deploying low-cost geophone sensors to accurately track these changes the sensor capabilities are still quite limited. To resolve these limitations, we have introduced more geophones and sensors in the latest version. These new sensors allow us to capture more and ...
