Aircraft and transport. Hawaii: red alert for Kilauea volcano

The column of smoke and ashes could almost reach 20 km -2 VIDEO

The Hawaiian Volcano Observatory Kīlauea, local station of the US Geological Survey (USGS) has brought to the red level the warning threshold for the state of the largest volcano in Hawaii, the Kilauea, from which according to the last bulletin has risen a a smoke column of more than 4 kilometers that could indicate the imminence of a significant eruption. The danger for air traffic in the area is the column of smoke and ash that could reach 20 kilometers in these hours; this is increasing in volume and is also slowly moving from the mouth to the north from the summit of the volcano, beginning to disperse its ashes that could fall into the national park of volcanoes and into the leeward areas, already alerted to the danger.

The latest bulletin also informs that earthquakes have increased, magnitude 3 or greater than 3 Richter, at a shallow depth and below the summit, which have already caused damage to the nearby highway and to various facilities within the park. The behavior of the volcano reminds the volcanologists of the USGS the terrible explosive eruption of 1924 occurred at the summit of Kilauea, also distinguished by hundreds of earthquakes of the same intensity.

Crossing a volcanic ash cloud is extremely dangerous for any type of aircraft or helicopter, even more so for an airliner with passengers on board. These dusts can be dangerous not only for flight activities, but can also affect airport operations on the ground. Small accumulations of ash can reduce visibility, make slippery runways and taxiways, infiltrate communications and electrical systems, stop services on the ground, damage buildings and parked aircraft. The accumulation of more than a few millimeters of these powders requires removal before the airports can resume full operations. The ash does not disappear (unlike snowfall) and must be disposed of in order to prevent it from being re-stabilized by wind and moving aircraft.
