As a student there are several ways in which we can help with geological disasters. The primary way is through donating money or goods to disaster relief organizations or through fundraisers we create. We can also give blood for those who may need it in the effected areas. As students, we will be unable to help with any other forms of assistance, as it requires trained professionals.
The main ways to minimize the effects of a geological disaster is by being properly informed and prepared. Having a warning system in place can help as well, as we can determine the likelihood of an event happening hours or days before it actually occurs. Preparing and being properly informed will give us the ability to either move out of the way or avoid devastating damage by being in the right place with the right equipment.
I hope I've helped! :)
