Boulder, CO, USA - The February issue of Geosphere , The Geological Society of America's Web science journal, is now online. Articles examine climate change in Arrow Canyon, Nevada, USA; faulting, magnetic anomalies vis-a-vie Colima volcano, the most active volcano in Mexico; and the architecture of oceanic plateaus.

This paper presents a magnetic study of fault zones in the volcanic terrains of the Colima volcanic complex in southwestern Mexico. The study shows that faults are characterized by magnetic anomalies, and illustrates how geophysics can be used to improve geological interpretations in young volcanic terrains. Colima is the most active volcano in Mexico, with a summit dome and several eruption events in the past decades. The area around the volcano is densely populated, including the city of Colima, and the study has implications for hazard assessments.
