Final answer:
Mount Krakatoa, located in the Sunda Strait, erupted in 1883 and caused a global impact, including shockwaves that circled the Earth and significant climate changes.
Step-by-step explanation:
The volcano that erupted in the Sunda Strait, causing the shock wave to travel around the world 7 times, is Mount Krakatoa.
The catastrophic eruption occurred in 1883 and was one of the most violent volcanic events in recorded history. Its shockwaves reverberated around the globe, and the eruption itself had profound effects on global weather patterns and climates, cooling the Earth's temperature by about two degrees Fahrenheit. Krakatoa's 1883 eruption was heard as far away as the coast of Africa, and the ash it spewed reached heights of about 50 miles into the atmosphere.
Although the official death toll was recorded as 36,417, local sources estimate that it could have been as high as 120,000. Today, Krakatoa remains an active volcano and continues to be closely monitored due to its history of powerful eruptions.
