Summary

Description
English: Popocatépetl volcano—the name is Aztec for “smoking mountain”—is one of Mexico’s most active volcanoes. The glacier-clad stratovolcano has been erupting since January 2005, with daily low-intensity emissions of gas, steam, and ash.

On January 2, 2021, the Operational Land Imager (OLI) on Landsat 8 captured this image of a plume rising from Popocatépetl (nicknamed El Popo).

On January 6, the Washington Volcanic Ash Advisory Center (VAAC) reported a volcanic ash plume that rose to around 6,400 meters (21,000 feet) above the volcano. Mexico’s National Center for Prevention of Disasters (CENAPRED), which continuously monitors Popo, warned people not to approach the volcano or its crater due to falling ash and rock fragments. Some ashfall was blown downwind to the city of Puebla, located about 45 kilometers (30 miles) away from the volcano.

At 5,426 meters (17,802 feet) above sea level, Popocatépetl is the second tallest volcano in Mexico (after Citlaltépetl). It is comprised of alternating layers of volcanic ash, lava, and rocks from earlier eruptions. The volcano is located around 70 kilometers (40 miles) southeast of Mexico City and more than 20 million people live close enough to be affected by a major eruption. However, most of the eruptions in the past 600 years have been relatively mild.
Deutsch: Der Popocatépetl — der Name ist Aztekisch für “rauchender Berg” — ist einer von Mexikos aktivsten Vulkane. Der von Gletschern bedeckte Stratovulkan eruptiert seit Januar 2005, mit täglichen wenig intensiven Emissionen von Gas, Dampf und Asche.

Der Operational Land Imager (OLI) auf dem Landsat 8 nahm am 2. Januar 2021 dieses Bild einer Aschewolke auf, die vom Popocatépetl aufsteigt.

Am 6. Januar 2021 meldete das Washingtoner Volcanic Ash Advisory Center (VAAC) eine vulkanishe Aschewolke, die eine Höhe von 6.400 Meter (21.000 Fuß) über dem Vulkan erreichte. Das Centro Nacional de Prevención de Desastres (CENAPRED), welches den Popocatepetl ununterbrochen überwacht, warnte die Öffentlichkeit davor, sich dem Vulkan und seinem Krater nicht näher zu kommen, weil Asche und Gesteinsbrocken hochgeschleudert werden und herunterfallen. Vom Wind abgetrieben ging etwas Asche über der Stadt Puebla nieder, die sich etwa 45 Kilometer enternt vom Vulkan befindet.

Mit 5426 Metern Gipfelhöhe ist der Popocatépetl der zweithöchste Vulkan in Mexico (nach dem Citlaltépetl). Er besteht aus sich abwechselnden Schichten von Vulkanasche, Lava und Gestein von früheren Eruptionen. Der Vulkan liegt etwa 70 Kilometer südöstlich von Mexiko-Stadt, und mehr als 20 Millionen Menschen leben nahe genug am Vulkan, um von eine großen Eruption betroffen zu sein. Allerdings waren die meisten der Eruptionen in den letzten 600 Jahren relativ mild.
