What would be an indication of activity within the supervolcano under Yellowstone National Park? a large number of earthquakes many small eruptions a mountain formation changing of ocean tides

A large number of earthquakes is a key indication of activity within the supervolcano under Yellowstone National Park. These tremors can signal the movement of magma within the earth, providing clues about potential eruptions. Scientists closely monitor seismic activity, and increased quake frequency or intensity can hint at shifts in the volcanic system. Many small eruptions could also indicate supervolcano activity, as these minor events can be precursors to larger eruptions. Frequent smaller eruptions show the volcano is not only active but also that pressures from beneath are changing, making it essential for researchers to keep a close eye on these signs for safety and preparedness.
