Where Volcanoes Are Born Most volcanoes form at the boundaries of Earth's tectonic plates, which are huge slabs of crust and ...

For decades, volcanologists believed that the primary trigger for explosive eruptions was a drop in pressure as magma rises toward the surface. When pressure falls, gases dissolved deep within the ...

In a lava lake, such as the one present from 2008-18 in Kilauea’s summit Halema‘uma‘u crater, we can sometimes visually observe these fluid motions as ripples or sloshing of the surface following ...

Scientists have discovered that shear forces inside rising magma can create gas bubbles long before pressure drops occur. The intensity of a volcanic eruption is shaped by how many gas bubbles develop ...

June 24 (UPI) --Changes in magma prior to eruptions make Indonesia's volcanoes among the most dangerous in the world, according to a study published Thursday by Nature Communications. Using chemical ...

Mount Rainier - one of many volcanoes found in the Cascade Range - is reflecting in the Reflection Lakes in Mount Rainier National Park in Washington State, USA. A seismic survey challenges the ...

Sessions are scheduled for Jan. 14 and 21 at Pāhala and Nāʻālehu public libraries, respectively. Come to the Kahuku Unit of ...

The extra magma doesn’t mean it’s more likely to erupt, scientists say. In fact, the better measurement helps them to understand its future. By Robin George Andrews Magma is the explosive lifeblood of ...

Researchers have mapped the magma plumbing system beneath Tonga's underwater volcano and discovered three magma chambers, two of which fed the record-shattering 2022 eruption. When you purchase ...

Subatomic particles called muons are born from cosmic rays bombarding the atmosphere. Because muons can penetrate objects, scientists are using them to peek inside volcanoes. This technique — called ...
