Hawaii’s Kilauea volcano could soon shoot 10-ton “ballistic rocks” up into the air, scientists are warning.

The U.S Geological survey cautioned residents about the possibility of “explosive eruptions” coming from the Big Island volcano — which has already displaced nearly 2,000 people and destroyed 36 homes and buildings since it started spewing lava and toxic gases into residential areas last week.

This kind of sudden, violent eruption would happen if lava flows from Kilauea’s crater down its inner tunnel and magma reaches ground water — creating steam pressure that would then explode, the USGS tweeted.

It could then shower the surrounding area with 10 to 12-ton molten rocks and send smaller marble-sized rocks within several miles of the crater.

“If an explosion happens there’s a risk at all scales,” Donald Swanson, a USGS volcanologist told the Washington Post.

There would also be “fine ash floating from the sky like snow” as far as 20 miles downwind, Swanson said.

Scientist warned they don’t know precisely when such an eruption could occur.

“We don’t know, and can’t tell precisely, when the conduit will empty of magma below the water table,” Swanson said. “Secondly, we’re uncertain as to how long it will take for conditions to generate an explosion once the conduit has been emptied below the water table. We expect that it’s quite a rapid process, but we really don’t know for certain.”

Local authorities said dozens of people evacuated the southeast end of the island in and around the neighborhood of Leilani Estates Wednesday.

Residents were also warned to stay indoor because of sulfuric air emanating from the volcano, called “vog” — or volcanic fog that can cause headaches, lung irritation and even induce asthma attacks.
