The reason a lava dam is not as strong as concrete is because when intensely hot lava hit water, it flash cooled and transformed into structurally weak pillow basalts, air pockets, hyaloclastite, and a yellow crumbly mineral called palagonite, all of which are made of water-quenched fragmented lava. One collapse of a lava bench in 2016 created such a big explosion of ash and steam that it could be seen from space. “We’re seeing nearly all of the hazards that Kilauea can generate right now with the exception of really large explosive eruptions from the summit,” Poland said. Once a new lava delta extends more than a few tens of meters (yards) from the old sea cliff, visitors should stay at least 300 m (330 yd) away from where lavais entering the ocean.

The good news: At this point, we’ve pretty much seen Kilauea’s full hand of hazards, Poland said, listing the lava entry into the ocean and other risks, like volcanic fog (“vogs”) of sulphuric acid, fast-moving lava and spattering gas emissions. A passenger on the boat, Kirk Olsen, wrote on Facebook that a piece of lava rock lodged itself on the handrail next to his elbow. As hot lava boils cool seawater, a series of chemical and physical reactions create a mixture of condensed, acidic steam, hydrochloric acid gas, and tiny shards of volcanic glass. The water inside it has been bubbling since then and … They eventually develop a channel as the walls get taller,” Klemetti said. Primary hazards include: Visitors to an active ocean entry should pay attention to warning signs that may be posted in the area. Lava entering the ocean builds a delta on top of unstable lava fragments along the steep submarine slope. When the lava of the melted core hit it, it would cause an enormous steam explosion. From nighttime through early morning, trade-wind flow typically blows the laze off shore and out to sea.
