I am a geologist by profession and training. This is an educational channel devoted mostly to spread of geological knowledge and education. I work hard to make the material you see presented to you in this short concise videos. Please support this channel by "LIKE"ing and sharing the videos and help them to be seen. I am making many videos every month. It is a constant stream of unique graphics and presentations of scientifically accurate and timely information about volcanoes. I am here for you to report everything about this fascinating subject. This is my expertise, my professional training, my education and my job.
Some of the thumbnail images in the videos are occasionally produced by recent advances in Artificial Intelligence. They are just pretty pictures that AI is producing when a text describes a volcanic event or geological phenomenon for them. They are by no means represent the reality and are used here only for their graphical merits.
