Okataina Volcanic Centre (New Zealand)
This complex unleashed a massive eruption just 800 years ago, while its Tarawera vent split a mountain in 1886. Colorful hot springs and steaming vents punctuate lush forests. The region draws tourists to Rotorua’s famous geothermal features. Recent magma studies show continued activity beneath the surface. The proximity to popular tourist destinations makes monitoring particularly important.
