Frequently Asked Questions
How is the global seismic activity level determined?
Activity levels are determined by the frequency and magnitude of earthquakes recorded globally within a 24-hour window. A “LOW” designation indicates that the number of high-magnitude events is below average.
Why are earthquakes recorded near volcanoes?
Seismic activity near volcanoes often indicates the movement of magma or tectonic adjustments within the volcanic plumbing system, which monitors utilize to track potential unrest.
