Strong explosion at Kilauea volcano sends ash up to 9.1 km (30 000 feet) a.s.l., Hawaii


A strong explosion took place at the Overlook vent within Halemaumau crater at Kilauea volcano's summit about 04:15 HST (14:15 UTC) on May 17, 2018, ejecting ash up to 9.1 km (30 000 feet) above sea level. The Aviation Color Code is at Red.

Continued emissions from the crater are reaching as high as 3.6 km (12 000 feet) above sea level and drifting generally northeast. 

Activity may again become more explosive at any time, increasing the intensity of ash production and producing ballistic projectiles near the vent. 

Ashfall has been reported in Volcanoes National Park, and may occur further downwind. Vog or volcanic air pollution produced by volcanic gas has been reported in Pahala. 

Ballistic projectiles may be produced should steam-driven explosions occur but impacts will be limited to an area around Halemaumau.

  1. News reports say that Hawaii’s Kilauea volcano erupted on 4 May 2018 while some rumbling had started a week earlier. The development prompted evacuations and declaration of state of emergency. Obviously , the ash and lava being emitted by volcano eruption into sky has potential threat to the residents in the nearby area of health issues as well. The potential threat was , however , indicated by this Vedic astrology writer in alerts of 11 October , 2017 in article – “Astrological probable alerts for the United States in 2018” – published in monthly Webzine of Wisdom Magazine from the US at wisdom-magazine.com/Article.aspx/4647/ on 1 December , 2017. The text of the alert closely related to the point reads in the article as :-
    “ May-June 2018. ……… There may arise need to deal with some widespread diseases in one or more vulnerable States or regions as follow for July-August in 2018 here in this article unless prompt measures are put in place at the initial stage when such a scenario appears on the scene. So a close watch in that direction by the concerned health departments in the Govt could be useful”.
    The place of likely occurrence referred to in May-June 2018 was mentioned like this in the article :-
    “July-August in 2018. …. .. Some States which may keep a watch on any developing such scenario in one or more vulnerable States or regions like … .. . Hawaii Island. Increased watch in one or more of said States against likely volcano eruption , fire , earthquakes , leakages of one or more commodities like chemicals or gas , could be meaningful”.
    The aforesaid details of alert on 11 October , 2017 leave one in no doubt that volcano eruption in May-June , 2018 in Hawaii island was indicated by this writer for more care and appropriate strategy.
