• Volcanic eruptions are significant geologic hazards. • Underwater volcanoes are challenging to study, yet they play an integral role in marine geology and may cause destructive tsunamis that can threaten coastal communities.

- Summary
Scientists have traced the creation of extensive lava fields along the Pacific Northwest’s seafloor to a series of underwater volcanic eruptions. These submarine volcanoes, difficult to monitor, have produced vast basaltic deposits that now cover large swaths of the ocean floor. The eruptions not only reshape marine geology but also pose significant hazards: the sudden release of magma and water can generate tsunamis capable of impacting coastal communities. While the exact timing and frequency of these events remain uncertain, the findings underscore the importance of monitoring submarine volcanic activity to better assess and mitigate potential tsunami threats.
