Óli Gneisti (English)<p>Having an ongoing volcanic eruption less than 50 km from my home doesn't change anything in my daily life except that I need to be aware if there is a chance of smog made up of gases such as sulfur dioxide. So wind is the key factor.</p><p>People are rarely killed by the lava from an eruption. If you are close enough the gas can be immediately fatal.</p><p>Eruptions beneath glaciers can cause massive life threatening floods.</p><p>The most frightening immediate danger is the pyroclastic flow.</p><p>It is, to quote Wikipedia: </p><p>> a fast-moving current of hot gas and volcanic matter (collectively known as tephra) that flows along the ground away from a volcano at average speeds of 100 km/h (30 m/s; 60 mph) but is capable of reaching speeds up to 700 km/h (190 m/s; 430 mph). The gases and tephra can reach temperatures of about 1,000 °C (1,800 °F). </p><p>This is what killed the people of Pompeii whose shapes have been preserved for the enjoyment of tourists.</p><p>None of these are the deadliest aspects of a volcanic eruption.</p><p>Long term pollution and a far reaching drop in temperature as well as other changes in weather, caused by gas expelled into the atmosphere, killed an estimated 20-25% of the population of Iceland in the aftermath of the 1783-1784 eruptions at Laki. It likely attributed to crop failures and famine in India, Egypt, Arabia and even Japan.</p><p><a href="https://social.linux.pizza/tags/Iceland" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Iceland</span></a><br><a href="https://social.linux.pizza/tags/VolcanicEruptions" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>VolcanicEruptions</span></a> <br><a href="https://social.linux.pizza/tags/Grindav%C3%ADk" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Grindavík</span></a></p>
