Viscosity is the attitude of the Magma to flow (high viscosity = low flow; low viscosity = high flow) and depends on its chemical composition.

People caught in their path have a high risk of death from severe crush injuries, drowning or asphyxiation or can be burned in a pyroclastic flow. The only protective measures from such hazards in the case of an eruption are to evacuate the potentially involved people from the exposed area.<br \/><br \/>Volcanic earthquakes can produce human losses where the quality and maintenance of buildings are scarce. In such a condition, small volcanic earthquakes can already produce damage or destruction to buildings, killing and injuring people.<br \/><br \/>Fires produced by eruptions can be responsible for among other, destruction of forests, wood stocks, buildings, factories, producing large damage to urban and rural areas.<br \/><br \/>Eruptions can also produce volcanic tsunamis: large sea waves reaching coastal areas and going far inland causing death, large-scale damage and destruction of coastal regions.<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-adf3218 elementor-widget elementor-widget-accordion\" data-id=\"adf3218\" data-element_type=\"widget\" data-widget_type=\"accordion.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-accordion\" role=\"tablist\">\n\t\t\t\t\t\t\t<div class=\"elementor-accordion-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-1821\" class=\"elementor-tab-title\" data-tab=\"1\" role=\"tab\" aria-controls=\"elementor-tab-content-1821\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon elementor-accordion-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-closed\"><i class=\"fas fa-plus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-opened\"><i class=\"fas fa-minus\"><\/i><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-accordion-title\" href=\"\">5.1 Consequences for the environment<\/a>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div id=\"elementor-tab-content-1821\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"1\" role=\"tabpanel\" aria-labelledby=\"elementor-tab-title-1821\"><p>\t\t<div data-elementor-type=\"wp-post\" data-elementor-id=\"1421\" class=\"elementor elementor-1421\">\n\t\t\t\t\t\t<div class=\"elementor-inner\">\n\t\t\t\t<div class=\"elementor-section-wrap\">\n\t\t\t\t\t\t\t\t\t<section class=\"has_eae_slider elementor-section elementor-top-section elementor-element elementor-element-1ee1e61 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"1ee1e61\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t\t\t<div class=\"elementor-row\">\n\t\t\t\t\t<div class=\"has_eae_slider elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-1ae8fe2\" data-id=\"1ae8fe2\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-column-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t<div class=\"elementor-widget-wrap\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-8f9d415 elementor-widget elementor-widget-text-editor\" data-id=\"8f9d415\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-text-editor elementor-clearfix\">\n\t\t\t\t<p>Volcanic eruptions can have strong negative effects for the environment.

Before a Volcanic Eruption<\/em><\/p><ul><li>Stay away from active volcano;<\/li><li>Be aware of emergency plans established by local and national authorities;<\/li><li>If you live near a volcano, active or dormant, be ready to evacuate at short notice.<\/li><\/ul><p><em>2.

As mudflows can move very fast, do not cross bridges or channels if a mudflow is approaching. Avoid also river valleys and low-lying areas.<\/li><\/ul><p><em>In case of falling ash:<\/em><\/p><ul><li>Stay away from downwind of volcano areas.<\/li><li>Listen to the radio; battery-powered radio or television is essential for listening to updated emergency instructions.<\/li><li>Avoid any contact with ashes: don\u2019t breathe freely, use a dust mask or hold a damp cloth over your face to protect the respiratory tract, wear long-sleeved shirts and long pants.<\/li><li>Use goggles (safety glasses that protect the eye area) in order to prevent harm by particulates and chemicals substances and if needed, wear normal eyeglasses instead of contact lenses.<\/li><li>Stay inside until the ashes have settled and then avoid the danger of roof collapsing by clearing heavy ash from flat or low-pitched roofs and rain gutters.<\/li><li>Close doors, windows and all ventilation channels in the house (chimney vents, furnaces, air conditioners, fans and other vents);<\/li><li>Avoid driving during heavy ash fall and if really needed, drive slowly (less than 40-50 km\/h);<\/li><li>Avoid also running car or truck engines as volcanic ashes can block them and damage moving parts.<\/li><\/ul><p><em>3.
