Magmas to Metals
No one wants to have an active volcano in their backyard (just ask Dionisio Pulido), but ancient eroded volcanoes can sometimes be literal goldmines for mineral ores.
Kīlauea Summit Eruption | Lava Returns to Halemaʻumaʻu
In March 2008, a new volcanic vent opened within Halema‘uma‘u, a crater at the summit of Kīlauea Volcano in Hawaiʻi Volcanoes National Park on the Island of Hawaiʻi. This new vent is one of two ongoing eruptions on the volcano. The other is on Kīlauea’s East Rift Zone, where vents have been erupting nearly nonstop since 1983. The duration of these simultaneous summit and
