Indonesia's Mount Ruang volcano erupted five times in a row, prompting the closure of a nearby airport and a tsunami alert.
About
Ruang is situated in the Sangihe Islands arc, North Sulawesi, Indonesia.
It comprises an island that is 4 by 5 kilometers wide, with a summit containing a partial lava dome reaching an altitude of 725 meters (2,379 ft).
From its summit, peaks such as Klabat, Siau, and Ternate can be observed in the south, north, and east, respectively.
The top of the mountain is partially filled with a lava dome formed as a result of activity in 1904.
Types of Volcanoes:
Stratovolcanoes vs. Shield Volcanoes
Stratovolcanoes: Steep, cone-shaped with more viscosity. Strato Volcanoes comprise the largest percentage (~60%) of the Earth's individual volcanoes, and most are characterized by eruptions of andesite and dacite, lavas that are cooler and more viscous than basalt.
Shield Volcanoes: Low-profile, resembling a shield lying on the ground.
Variety of Volcanic Features
