Mauna Loa is an active shield volcano located in Hawaii and is the largest subaerial volcano on our planet. It is part of the Hawaiian hotspot chain and has erupted thirty-four times since its first well-documented eruption in 1843. This high frequency of activity contrasts sharply with extinct volcanoes like Demavand or Chimborazo. Extinct volcanoes have no magma supply and are unlikely to erupt again over geological timescales. Mauna Loa’s frequent basaltic lava flows and monitored seismic activity confirm it is very much alive, making it a critical site for global volcanic research and hazard monitoring.
