Volcanoes tend to have seismicity that waxes and wanes over time. That’s considered normal and not necessarily a cause for concern. Let’s check on Mount Adams to see what USGS scientists are doing to learn more about its recent earthquake activity and what it could mean for this Cascade Range volcano.
