Ethiopian Volcanoes and Eruptions

As of October 2024, 49 volcanoes are actively erupting worldwide, including Ethiopia's Erta Ale. Recent volcanic activities include Kanlaon in the Philippines, which erupted after months of unrest, and a significant magma intrusion near Ethiopia's Fentale volcano, causing evacuations. In Indonesia, Iya volcano's alert level was raised due to increased tremors, indicating potential eruptions. Despite these activities, the likelihood of eruptions varies, with some showing decreased activity. The video concludes with a list of erupting volcanoes and acknowledgments.
