Watch the video below and find out more about the Ring of Fire and how it had created the many disasters in 2018.

Where is the Ring of Fire?
Why are there more seismic activities (volcanic eruptions and earthquakes) at the Ring of Fire?
When did Anak Krakatoa erupt?
What type of volcano is Anak Krakatoa?
What are the impacts of volcanic eruption?
Who are affected by volcanic eruptions?

Update:
Mount Anak Krakatau in the Sunda Strait has shrunk to almost a third its original height, from 338 meters to 110 m. The scale of the collapse of anak Krakatoa can be seen from the satellite images below. The Volcanology and Geological Disaster Mitigation Center (PVMBG) estimated that the volcano reduced to between 40 million and 70 million cubic meters in size from a mass of about 150 million to 180 million m3, following eruptions that occurred between Dec. 24 and 27.
