- In 1912, the Novarupta eruption near Mount Katmai in Alaska was the 20th century's most prolific volcanic event, causing global cooling and reshaping the landscape.
- Geologists discovered that magma from Mount Katmai migrated sideways to Novarupta, revealing the first evidence of 'coupled volcanoes' that share or exchange magma.
- In Iceland, events like the 2014 Bárðarbunga eruption and the alternating activity between Fagradalsfjall and Svartsengi fissure systems provided real-time examples of volcanic coupling.
- Machine learning algorithms, such as those developed by Zach Ross, identified a shared magma reservoir between Hawaii's Kīlauea and Mauna Loa, challenging the assumption of their independence.
- Research in Greece's Santorini region, using advanced sensors, showed magma movement between Santorini and the underwater Kolumbo volcano, indicating coupling and improving eruption forecasting.
- Coupled volcanoes exhibit diverse behaviors, including alternating or simultaneous eruptions, and magma can travel long distances laterally or from deep shared sources.
