Mauna Loa, the world's largest active volcano, has erupted on the Big Island.
Manua Loa forms a twin with Mauna Kea, where the telescopes are.
The main highway, known as the Saddle Road, runs between them.
The Big Island is essentially these two peaks rising from the ocean floor.
The summit of Mauna Loa houses the atmospheric observatories and is
home of the CO2 Keeling Curve, where the longest continual direct CO2
measurements have been taken.
The last major eruption on the Big Island was Kīlauea, further to the south,
in 2018.
