Yellowstone Supervolcano Eruption 2024 Eruption. Yellowstone volcano observatory scientists continue to examine data from the black diamond pool area of biscuit basin, where a hydrothermal explosion took place on july 23, 2024. Geologists observed fountaining eruptive fissures and active lava flows on the floor of nāpau crater, just downrift (northeast) of the september 15 eruptive fissure.
Hydrothermal explosions are not an indicator that a volcanic eruption is brewing, according. Precursors to volcanic eruptions include strong earthquake swarms and rapid ground deformation and typically take place days to weeks before an actual eruption.
