What would a Yellowstone super-eruption actually mean for Earth?

SETI Institute volcanologist Dr. Kayla Iacovino joined NewsNation to discuss the potential impact of a Yellowstone super-eruption—an event so large its effects could be comparable to a major asteroid impact.

Watch the conversation to learn more about supervolcanoes, the hazards they pose, and what scientists understand about these rare but powerful events.

Using satellite geodetic data, researchers have identified two distinct, active magma reservoirs beneath Nicaragua's Masaya volcano by observing precise patterns of localized ground deformation.

Bradyseism (Volcanology 🌋)

Bradyseism is the gradual uplift or descent of part of the Earth's surface caused by the filling or emptying of an underground magma chamber or hydrothermal activity, particularly in volcanic calderas. It can persist for millennia in between eruptions and each uplift event is normally accompanied by thousands of small to moderate earthquakes. The word derives from the anc...

Understanding an eruption means linking what we see at the surface to processes occurring deeper underground.

A useful reminder that complex fluid phenomena often require multiple scales of observation.

A lava flow records its own thermal history.

Its final shape reflects how the molten rock moved, exchanged heat with its surroundings and solidified.

Deep-sea lava fields offer clues about fluid flow and phase change under extreme conditions.

Igneous rock (Volcanology 🌋)

Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rocks are formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in a terrestrial planet's mantle or crust. Typically, the melting is caused by one or more of three proce...

#Krakatau’s 1883 explosion, the mystery blast of 536, #Samalas in 1257, #Laki in 1783, and #Tambora in 1815, show how #volcano-driven cooling shifted #agriculture, #disease, and #migration. Historical #climate shocks like these offer clues to how modern society may handle rapid planetary change.

Lithophysa (Mineralogy 💎)

A lithophysa is a felsic volcanic rock with a spherulitic structure and interior cavity with concentric chambers. Its outer shape is spherical or lenticular. They vary in size from very small up to twelve feet in diameter depending on the age of the magma chamber. These rocks are usually found within obsidian or rhyolite lava flows. Lavas low in feldspar ...

Verneshot (Volcanology 🌋)

A verneshot is a hypothetical volcanic eruption event caused by the buildup of gas deep underneath a craton. Such an event may be forceful enough to launch an extreme amount of material from the crust and mantle into a sub-orbital trajectory, leading to significant further damage after the material crashes back down to the surface.

Volcanology (Earth sciences 🌍)

Volcanology is the study of volcanoes, lava, magma, and related geological, geophysical and geochemical phenomena. The term volcanology is derived from the Latin word vulcan. Vulcan was the ancient Roman god of fire. A volcanologist is a geologist who studies the eruptive activity and formation of volcanoes and their current and historic eruptions. Volcanologists frequ...

Ejecta (Volcanology 🌋)

Ejecta are particles ejected from an area. In volcanology, in particular, the term refers to particles including pyroclastic materials that came out of a volcanic explosion and magma eruption volcanic vent, or crater, has traveled through the air or water, and fell back to the ground surface or ocean floor.

More than 3.1 billion years ago, before modern plate tectonics existed, surface water was transported deep into Earth’s interior to generate magma and drive volcanic activity.
