Is Mauna Loa due to erupt?

Mauna Loa is not currently erupting. … Mauna Loa like Kīlauea has a summit caldera and two active rift zones extending from its summit.

What type of eruption was Mauna Loa 1950?

lava flows
The 1950 eruption on the Southwest Rift Zone of Mauna Loa sent massive lava flows through the upper reaches of what is now the Kahuku Unit of Hawaiʻi Volcanoes National Park.

Alkalic postshield activity began about 60-70 thousand years ago and its youngest known eruptions occurred around 4000-5000 years ago.

How hot is lava?

The temperature of lava flow is usually about 700° to 1 250° Celsius which is 2 000° Fahrenheit.

Once that happens the magma (molten rock) will rise toward the surface (it floats).
