No, do not roast marshmallows over Hawaii volcanic vents


USGS: Erm…we will should say no, that is not secure. (Please do not strive!) If the vent is emitting loads of SO2 [sulfur dioxide] or H2S [hydrogen sulfide], they’d style BAD. And for those who add sulfuric acid (in vog, for instance) to sugar, you get a fairly spectacular response.

What commonly used volcanic terms mean

USGS: The eruption at Kilauea proper now could be impacting a small portion of the Huge Island. Lava flows are lively on the jap tip of the island, in decrease Puna, and Hawaii Volcanoes Nationwide Park is closed as a result of small explosions occurring at Kilauea’s summit. However the Island of Hawaii is made up of 5 volcanoes, and solely Kilauea is erupting.

Even when there have been to be a change in exercise at Kilauea, it will not affect Hilo or Kailua-Kona (the most important cities on the island), that are situated on completely different volcanoes. The largest impacts may be vog, however that has been a persistent situation on the island for many years. You’ll be able to truly get real-time vog info at websites across the island from the Hawaii Division of Well being at

Q: However what concerning the vog?

Fast-moving lava sparks immediate evacuations in Hawaii

USGS: Vog has been persistent on the Huge Island for many years — it is a product of any lively eruption. It obtained worse in 2008, when the summit eruption began. Throughout some kinds of climate circumstances, it could actually convey a haze to Kailua-Kona, however it isn’t a big well being hazard. There’s fairly a bit extra vog being generated within the decrease East Rift Zone by the present eruption, nevertheless it nonetheless isn’t a serious concern in Kailua-Kona.

For extra details about vog, take a look at Actually, you’ll be able to see a map of vog circumstances all through the island at!

Q: Will the explosions on the summit proceed for weeks? Months? Years? A long time?

USGS: We all know how lengthy related explosive exercise has lasted (the 1924 eruptions went on for about 2.5 weeks), however we will not assure that the exercise now will observe the identical sample.

Q: Is there an estimate on quantity of lava stream but?

USGS: Not but. Lava stream volumes are terribly troublesome to measure, however we’re engaged on numerous technique of figuring out eruption charges (together with topographic mapping because of a NASA airplane that’s on web site, and in addition measuring gases, which can be utilized as a proxy for effusion price).
