Welcome to the G 148 Volcanoes and Earthquakes Open Educational Resources (OER) space.  This space collects OER materials on volcanoes and earthquakes along with their associated hazards with a focus on the Pacific Northwest. These materials have been designed to support the G 148 Volcanoes and Earthquakes course at Portland Community College but can be used to support any earth science course that investigates volcanoes and earthquakes and their associated hazards.
