June 13, 2022 — Thermal camera timelapse of Kīlauea summit lava lake growth

This timelapse sequence shows the evolution of the lava lake and rise of the crater floor in Halema‘uma‘u, at the summit of Kīlauea Volcano, since the eruption start in September 2021. Much of the the crater floor rise is driven by lava supplied beneath the surface crust. The camera is located on the west rim of the summit caldera, looking east.

Between January 14-15, 2022, volcanic eruptions destroyed much of Hunga Tonga-Hunga Ha'apai, an uninhabited island in the Tonga archipelago in the southern Pacific Ocean. A plume of ash rising 36 miles into the atmosphere blanketed the neighboring Tongan islands.

Seafloor features such as sulfide mounds and chimneys are prominent evidence of hydrothermal activity. These features, whether active or dormant, are just the tip of the iceberg, so to speak; much of the “plumbing” of hydrothermal systems exists beneath the seafloor surface.

Critical to scientific operations aboard the Escanaba Trough expedition is the submersible robots Sentry and Jason. Owned and operated by the Woods Hole Oceanographic Institute (WHOI), these robots allow researchers to observe seafloor features and collect data from depths seldom visited by humans.
