Jedes Jahr brechen rund 50 der ungef\u00e4hr 1.500 aktiven Vulkane auf unserer Welt aus. Die meisten von ihnen finden wir um den Pazifik herum in einem als 'Feuerring' bekannten G\u00fcrtel. Auch in Europa gibt es Vulkane wie den \u00c4tna oder den Vesuv, die schon viele Male ausgebrochen sind.<\/p>\n<\/div>\n

Mindestens 500 Millionen Menschen leben in der N\u00e4he aktiver Vulkane. Bei einem Ausbruch k\u00f6nnen Gebiete in Vulkann\u00e4he von Asche und rotgl\u00fchender Lava bedeckt werden.<\/p>\n

Manchmal werden Felder und Geb\u00e4ude darunter begraben. Giftige Gase, Wolken gl\u00fchender Asche oder Lavastr\u00f6me k\u00f6nnen alles und jeden t\u00f6ten, der ihnen im Weg steht. Gl\u00fccklicherweise helfen uns heute im All stationierte Satelliten, die gef\u00e4hrlichsten Vulkane zu erkennen.<\/p>\n

Die ESA-Satelliten Envisat und ERS studieren Vulkane auf unterschiedlichste Arten. Ihre Kameras zeigen uns die Lavastr\u00f6me und Aschewolken. Infrarot-Instrumente stellen fest, wenn hei\u00dfes Magma nach oben str\u00f6mt.<\/p>\n

Mit Radar kann die 'Atmung' der Vulkane beobachtet werden, bei der geschmolzenes Gestein in ihrem Inneren in Bewegung ger\u00e4t. An dem Anschwellen der Oberfl\u00e4che um nur wenige Millimeter erkennen wir noch vor einem Ausbruch, dass sich Druck im Vulkan aufbaut. Andere Sensoren bemerken Gase und Teilchen, die in die Luft abgelassen werden.<\/p>\n

Diese Daten retten Leben und helfen uns, den Zeitpunkt des n\u00e4chsten Ausbruchs vorherzusagen. Au\u00dferdem sind Satellitenkarten der betroffenen Gebiete bei der Rettung und Bergung behilflich.<\/p>","protected":false},"excerpt":{"rendered":"
