Geochemical analysis of erupted tephra samples over the past decade help scientists understand the temperature of Kilauea’s shallow magma system under the summit — and things have been “heating up!” ...

These measurements reflect the temperature of the lava at the Earth’s surface—in our ambient atmosphere, which on a delightful day at Kaluapele might be around 75°F (24°C). Once magma reaches the ...

Volcanos are releasing ash and smoke into the atmosphere on three continents. That might be making you think back to your elementary school science class when you probably studied volcanoes and lava.

Magma is the molten material beneath the Earth's crust. It usually collects in a magma chamber beneath a volcano, and can then be injected into cracks in rocks or issue out of volcanoes in eruptions.

Learn how one of Earth’s most powerful volcanoes, Japan’s Kikai caldera, is refilling with magma from below.

In A Nutshell Japan’s Kikai Caldera, which produced probably the largest eruption of the past 10,000 years, appears to be ...
