An active 1.5-km-long lava flow on the NW flank was visible in satellite images on 1 December. Continuous tremor transitioned to episodic bursts during the morning of 2 December, but by 3 December a decrease in seismic activity and surface temperatures suggested another pause in lava effusion. The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch.	Ongoing
Stromboli (Italy), INGV Catania Section	Volcanic activity report for Stromboli (Italy), 27 November-3 December 2019 INGV reported that during 25 November-1 December activity at Stromboli was characterized by ongoing explosive activity mainly from three vents in Area N (north crater area) and at least three vents in Area C-S (south central crater area). Low-to-medium-intensity explosions from Area N occurred at a rate of 7-11 events per hour and ejected lapilli and bombs 80-150 m above the vents. Ejected tephra fell onto the flanks and some blocks rolled a few hundred meters along the Sciara del Fuoco. Medium-intensity explosions from Area C-S occurred at a rate of 4-8 events per hour and ejected coarse material to heights less than150 m above the vents. Material was deposited along the upper parts of the Sciara del Fuoco.	Ongoing

In Deutschland gibt es momentan keine aktiven Vulkane. Der Vulkanismus in Deutschland in den verangengen Jahrentausenden bzw. Jahrmillionen wurde durch Hebung der Alpen verursacht. Dass dieser Prozess noch nicht abgeschlossen ist, zeigen kleinere Erdbeben vom Rheingraben bis zur Kölner Bucht. Die Vulkane, die es in Deutschland gibt spucken zwar zur Zeit keine Lava aus, aber es gibt in Deutschland an vielen Orten heiße Quellen. Diese Thermalquellen sind ein Zeichen dafür, dass Wasser im inneren der Erde erwärmt wird. Vulkanaktivitäten aus vergangenen Zeiten sieht man in Deutschland z.B. auch am Kaiserstuhl in der oberrheinischen Ebene und am Rand der Schwäbischen Alp.
