Hawaii volcano eruption update: What is Olivine?


Since this unprecedented spouting began, residents have battled fissures spewing massive lava springs, sulphuric gasses in the air, shards of glass in the wind, ash clouds, and lava haze mount the barricade off the ocean. 

So it’s a welcome surprise to many to see a less sinister side of the volcano, in the feather of the green crystal Olivine.

The stones are being spotted in gardens and precincts near the active fissures. 

U.S. Geological Survey (USGS) scientist Wendy Stovall disclosed the phenomenon is to be expected.

She bid: “It’s pretty common. There’s often olivine in rocks all over Hawaii.”

What is Olivine? 

Olivine, one of the most communal minerals on earth, is a rock-forming mineral, typically found in igneous astounds (formed when molten rock, or lava, solidifies).  

Most Olivine bring about at the Earth’s surface is within the rocks at divergent tectonic plate frontiers and hot spots – just like Hawaii. 

Olivine crystallises at a very high-priced temperature, meaning it is one of the first minerals to crystallise from magma.

This is why the little green gems can be seen raining down tight-fisted lava flows, as they would have been sitting within the volcano already. 

Ms Stovall conveyed: “It really is one of the first things to form.”

The ones being spotted in individual’s gardens would have “just kind of fallen out” of the lava as it spews from the lively fissures. 

Olivine is very easily weathered, so it is most commonly endured at the earth’s surface in the form of sand – resulting in Hawaii’s green strands. 


Olivine is the cause of Hawaii’s green beaches.

What is the up to the minute from Kilauea?

The activity, which began on May 3, is being cited as an unprecedented occurrence, as there are two eruptions occurring simultaneously.

The first is the eruption at Kilauea’s climax crater, and the second along a six-mile string of 25 fissures down its east flank, discerned as the East Rift Zone. 

The USGS reported a small explosion today, assassinating more ash high into the atmosphere, putting communities in the southern play a part of the Big Island at risk. 

Since the eruption began, the volcano has destroyed approximately 600 stamping-grounds and forced thousands into temporary shelters. 

Power and telephone specialties have been damaged, and huge swathes of land and roads be enduring been wiped out. The damage to the island’s geothermal plant, which was inundated with lava, is even now unknown. 

No one has been killed by this period of activity, but one man was seriously hurt when he was hit in the leg by a lava bomb. 

Kilauea has been in a constant cycle of interest since 1983, turning eruptive after a magnitude 6.9 earthquake cuffed the area in late April.
