Correct Answer: (b) Indonesia
Solution:Kara katoa (Krakatau) volcano is in the Sunda Strait between Java and Sumatra island in Indonesia. The island of Krakatoa has one of the numerous volcanoes situated across the Pacific basin, where two massive tectonic plates collide. The Indo-Australian and Eurasian plates
continually collide, resulting in a great deal of volcanic activity. Geologists refer to this area as the Ring of Fire. Krakatoa has erupted several times in history, but it is most known for the sequence of massive explosions that occurred on August 26th and 27th, 1883. A plume of steam and debris started erupting from the collapsing caldera in 1927, startling several Javanese fishermen - Krakatoa had awoken after 44 years of dormancy. Within a few weeks, the rim of a new cone rose above sea level. Within a year, it had grown into a tiny island known as Anak Krakatoa or "Child of Krakatoa." Anak Krakatoa has continued to erupt regularly, albeit gently and with minimal risk to the surrounding islands. The most recent eruption occurred on March 31, 2014.
