Hawaii Volcano Update May 24th, 2018

Hawaii Kilauea Volcano Eruptive Vent Below
A Vent is Any opening at the Earth's surface through which magma erupts or volcanic gases are emitted. The below picture shows you where the recent volcanic eruption started in a volcano vent called Pu‘u ‘Ō‘ō cone at Kīlauea Volcano.

LAVA FISSURES

During the current eruption in Hawaii several fissures have opened and the lava emerging from these fissures is responsible for much of the damage.
Fissures:in geology, a fissure is a fracture or crack in rock along which there is a distinct separation; fissures are often filled with mineral-bearing materials. On volcanoes, a fissure is an elongate fracture or crack at the surface from which lava erupts. Image Below is a Fissure.

ERUPTION STYLE: the "Curtain of Fire"
As fluid, gas-poor basaltic magma rises up through a fissure, it is extruded at the surface as a wall of incandescent, liquid-to-plastic fragments known as a curtain of fire.

Two such eruptions are shown below from extrusive events on the Kilauea volcano, Hawaii.

Current Hawaii Eruption 22 Fissures!! Fissure Map: May 9th, 2018.
This thermal map shows the fissure system forming during this current eruption. The fissures are numbered F1, F2, F3, etc... The lava erupting from these fissures or huge cracks in the eart is destroying forests and buildings, including homes and cars in Leilani Estates. The black and white area is the extent of the thermal map. Temperature in the thermal image is displayed as gray-scale values, with the brightest pixels indicating the hottest areas. The thermal map was constructed by stitching many overlapping oblique thermal images collected by a handheld thermal camera during a helicopter overflight of the flow field. The base is a copyrighted color satellite image (used with permission) provided by Digital Globe.

Lava from Fissure 22
Helicopter overflight of Kīlauea Volcano's lower East Rift Zone shows the lava channel emerging from Fissure 22 (not visible, but to the center, far right of the image). The lava is flowing downhill, from right to left in the photo.
