Lava flows are masses of magma that pour onto ... called alkaline lava, has an extremely low viscosity, making it almost as fluid as water. Alkaline lava has a melting temperature in excess ...

At Ol Doinyo Lengai in northern Tanzania for instance, the lava flows at temperatures so low it is possible (though ... Lava with less silica in it has lower viscosity, meaning it is less thick ...

As a shield volcano, Kilauea’s eruptions typically produce low-viscosity lava flows, which can travel quickly and cover large ...

A lava tube may also form, beneath the surface of the ground, when low viscosity lava develops a hard crust through which lava flows.

In a field test of their instrument, University at Buffalo researchers gathered viscosity data from lava flows at the Litli-Hrútur eruption in Iceland. Disclaimer: AAAS and EurekAlert!
