This video shows an eruption of Indonesia’s Mount Sinabung
Footage of a volcano eruption has been viewed thousands of times in multiple posts on Facebook and Twitter alongside a claim it shows the eruption of Mount Semeru on the Indonesian island of Java in 2020. The claim, however, is false; this video has circulated online since at least 2014 and shows an eruption of Mount Sinabung, a volcano in Sumatra.
The 30-second footage was posted here on Facebook on December 1, 2020. It has been viewed more than 2,100 times.
The Indonesian-language post translates to English as: “Mount Semeru erupted on Sunday (11/29/2020). May the universe be peaceful.”
However, the claim is false.
A combined reverse Google image and keyword search found a longer version of the video posted here on January 21, 2014, on the YouTube channel of Photovolcanica.
The channel describes itself as a provider of “videos of volcanoes and geothermal features from around the world”.
The title of the 51-second video reads: “Pyroclastic flows and close up of collapsing lava lobe at night, Sinabung Volcano, Indonesia”.
The caption's states, in part: “Animation (Timelapse) shows pyroclastic flow at Mount Sinabung, Sumatra. Further, a close-up of the lava lobe is shown including the collapse of the lobe front leading to a pyroclastic flow. Movement of the lobe prior to collapse is just about visible.”
Below is screenshot comparison of the footage in the misleading post (L) and the YouTube video (R):
Mount Sinabung is a volcano located in Indonesia’s North Sumatra province.
