Magma Migration and Resupply during the 1974 Summit Eruptions of Kilauea Volcano,211 Hawai'i

摘要

Three brief eruptions - the longest lasting 3 days, the shortest only 6 hours -211u001etook place in the summit region of Kilauea Volcano during the last half of 1974: 211u001eJuly 19-22, September 19, and December 31. These eruptions followed an inferred 211u001econstriction of the upper East Rift Zone (ERZ) supply conduits to the long-lived 211u001eMauna Ulu eruption in early 1974, causing magma and excess pressure to accumulate 211u001ebeneath Kilauea's summit.
