Ah, the innocent days before everything changed! HVO’s weekly Volcano Watch column on March 22 discusses the fluctuating levels of Kilauea’s lava lake, and new technology being used to measure it.
Also, as was usual for Volcano Watch posts before the current eruption, the end of that entry provides a status update for Kīlauea, Puʻu ʻŌʻō, and Mauna Loa. This was the status quo before fissure 8 became the New Normal.
