At present, scientists and geologists are working on new technologies in order to predict these types of disasters and carry out preventive measures to reduce the negative impact as much as possible, advances have been made especially with storms, cyclones and other similar without However, there are natural phenomena that are too unpredictable, making it difficult to reduce damage.
