Comments by "Michael Deierhoi" (@michaeldeierhoi4096) on "Why Iceland's lava is so hard to stop | About That" video.

  1. Lava is heavier than concrete 2.9 g/ml vs 2.4 g/ml. Just sayin'.

  2. ​ @jeffreywickens3379  117 years it not much time at all in the larger scheme of life. These people hadn't had an eruption in their area in 800 years as another had indicated. If YOUR house was destroyed by an eruption next week you would be just as upset as the these other people you hear about in Iceland!!

  3. Look up what the eruption of Kilauea in 2018 did to Lalani estates! Hundreds of homes destroyed by the lava flows. Or the eruptions from Cumbre Vieja in the Canary Islands a few years ago that also destroyed dozens of homes. There was no way to divert those lava flows as they were too large to divert. You need to understand the different kinds of volcanoes that produce thinner vs thick lavas. The thinner lava is called basalt and flows faster and also much hotter and thus is harder to slow down except with barriers. The other kind of lava is from a more explosive volcano like Mt Etna which produces pyroclastic flows which are much more dangerous to life. They can cause other serious problems, but that you can find out for yourself.

  4. It is most definitely expensive to build a wall several km long that is up 8 m high. The authorities in Iceland are clear about that which is why they needed to be sure where the wall would go up so that it was most effective.

  5. Sure if money was no object!? 🙄. But you didn't think about that did ya now??

  6. Amazing!! It's like you didn't watch the video at all!! 🙄

  7. So far the people on this part of Iceland have effectively diverted the lava flows from the eruptions away from their town and protected the power plant. People actually have livelihoods to protect. This isn't about some clueless carefree lifestyle living in an RV.

  8.  @DaveC2729  This wasn't about me being offended, but rather simply stating my opinion which is what the comments section is meant to do. Take it or leave it.

  9. This last eruption in March 16 did in fact occur without warning because there was very little earthquake activity preceding it.

  10. He should have also mentioned the larger threatening volcanoes to the east for better context!

  11. The narrator in this video stated the point clearly that the wall buys them time which it has. After all what else can they do? They can raise the wall a little more, but even if the eruption keeps happening obviously the threat to infrastructure increases and it's true the wall can only be raised so much. And even if you buy up the homes there is still the power plant which supplies a significant amount of hot water and power to the Reykjanes Peninsula where these eruptions are occuring. Further the town of Grindavik is in a strategic location for a good fishing port. That can not be cast aside so easily. It is one of the few ports on the southern coast of Iceland.

  12. He was probably confusing concrete with cement. The latter does have a density of half that of basaltic lava. Basaltic lava is about 17 % more dense than concrete at 2.9 g/ml vs 2.4g/ml. Regardless your point is correct.

  13. You can also not live on the Gulf Coast or east coast of the US where one has a greater chance of being hit by a hurricane. Or you could also not live east of the Rocky Mountains to the coasts where tornadoes are common. And that is just the beginning when talking about natural hazards in the US alone. So what was your comment about again!?!?

  14. People often ask very ignorant questions. People are like that.

  15. So based on that one statement you are judging the whole video?! 🙄

  16. I didn't see any hysteria in this video. What hysteria are you referring to?

  17. Read some of these comments you get an idea.

  18. The lava from this eruption is hotter because it is basaltic lava which is the hottest kind of lava. Up to 1200 C. It isn't just Iceland that produces volcanoes that erupt basalt, but also Hawaii does at Kilauea for example. The lava from volcanoes like Mt St Helens is cooler 800-900 C but thicker too resulting in explosive eruptions on occasion and thus more dangerous.

  19. Living on the US Gulf Coast and east southeast coast is also expensive. Guess why? Living in much of the eastern US may not be expensive everywhere, but it is quite vulnerable to tornadoes and flooding!!
