People have tried to stop lava from flowing. This is why they failed

(CNN) Body fat way to stop lava.

“The runs cannot be stopped, but people have attempted in the past, ” said Benjamin Andrews, director of the Global Volcanism System at the Smithsonian National Museum associated with Natural History.

Flows can and have already been diverted, though. The most famous instance, Andrews cites, was in 1973 when the Eldfell volcano exploded on Heimaey , a small island in Iceland.

“In that will event, huge pumps were utilized to spray the advancing lava along with seawater — but this work did not stop the flow, instead it redirected the flow plus prevented it from inundating the particular harbor, ” he said, incorporating that portions of some cities were overrun with lava. Anyone died as a result of the eruption.

In other instances, Andrews said, bombs were utilized in attempts to divert a lava flow without success.

Challenges

Andrews described several challenges within stopping lava flow.
For starters, lava can be dense.
“It may flow like sticky viscous, thick treacle, but is more dense than concrete, ” he said. This means body fat point in putting up Jersey wall space in front of a flow because the lava will “bulldoze them out of the way. inch
A few have thought to spray the lava flow with water, hoping it can be heading cool and freeze the front from the flow. But the extreme heat at the rear of the crust, which is still molten, enables the flow to continue.
Andrews did declare flows can be diverted, but then will be certainly the problem of where the diverted lava goes.
“This problem is most easily highlighted with the example situation where We divert the lava flow in order to save my house but as a result the lava flow destroys someone else’s house, inch he said. “As a result of both of these factors, lava flows are generally not halted or diverted. ”

The consequences

The particular lava has flowed. The damage is completed. Now, there’s getting rid of the stone that’s left from the flow.
“In many instances the rock is remaining in place, ” Andrews said since the volume of rock and the effort needed to break it apart and take it off is generally cost-prohibitive.
But sometimes, it needs to become done. Like in October 2014 once the Kilauea volcano erupted , lava crossed over the major road called Cemetery Street, according to County of Hawaii Public Functions Department . Crews removed the particular lava that blocked the highway and a restoration project began. The particular solidified lava became an appeal for a while, CNN affiliate KHNL reported in 2015. The task to remove the lava and bring back Cemetery Road began in Oct 2015 and was completed in Dec 2015. The project, public functions said, was completed within the $150, 000 budget.
