Volume predictability of historical eruptions at Kilauea and Mauna Loa volcanoes

Cumulative volumes of eruptions at the Kilauea and Mauna Loa volcanoes in Hawaii appear to fit a volume-predictable model (i.e., the volume of an eruption episode is approximately proportional to the time since the previous episode) for many larger episodes during long periods of time (decades). This observation suggests that the magmatic pressure of each volcano tends to drop to a common level at the end of these episodes during each such period. ?? 1989.
