We developed this Natural Hazards book to fill the void we found and contribute a Canadian version to the public. We both feel that Open Education Resources (OER) are an excellent way to share the body of knowledge and work of those in the Physical Geography discipline. Each chapter in this book started with a chapter drawn from another OER and then edited to our own material we have used while teaching our classes in Natural Hazards for over 15 years. We will use the feedback from our students in 2021 and 2022 classes to finalize this book too.
