At approximately 10:00 AM local time yesterday, a sudden small hydrothermal explosion occurred in Yellowstone National Park's Biscuit Basin thermal area, roughly 2.1 miles (3.5 km) northwest of Old Faithful. Numerous visitors captured videos of the event. The explosion, which seems to have originated near Black Diamond Pool, caused damage to the boardwalk, but no injuries were reported. For visitor safety, Biscuit Basin, including its parking lot and boardwalks, is temporarily closed. However, the Grand Loop road remains open. Yellowstone National Park geologists are currently investigating the incident. Source: Yellowstone Volcano Observatory volcano activity update 24 July 2024

It seems that the volcano entered a new eruptive sequence. Judging from the latest Sentinel-2's thermal radiation from 19 July, a new submarine explosive activity started to take place approx. 600 meters off the coast of Okinahama Beach, located on the south of the island. Whether the activity will continue and escalate into phreatomagmatic-type, is not clear yet. Phreatomagmatic activity (also known as surtseyan) means that erupting magma reacts with external water, e.g. groundwater, lake water, sea water etc. The recent eruption phase occurred between late October and mid-December last year, during which the new J-shaped island grew to the south of the island. However, the morphology of the island was affected by strong ocean wave erosion. Since the edifice consisted solely of loose, juvenile lava material, it was highly prone to collapse into the water and gradually disappeared from view.
