This is peanut eruption. Cannot compare to coming eruption from anak krakatoa, which growing at 20 in per month and current height 230 m. When krakatoa erupted, it was 830m high causing catastrophe worldwide, mini ice age, tsunami etc.
smaller eruption than krakatoa, tambora and much smaller than the super volcano toba in sumatra. besides yellowstone, top 3 largest volcanic eruptions happened in indonesia. toba eruption was many times larger than yellowstone. sg is doomed.
