ABSTRACT: The eruption of the Laguna Hule explosion crater formed the depression now occupied by Laguna Hule (10[degrees]17'50" N, 84[degrees]12'43") and two other lakes, and apparently deposited volcanic tephra in nearby Laguna Maria Aguilar (10[degrees]18'09" N, 84[degrees]11'24").
Laguna Hule and two smaller lakes occupy the floor of a volcanic depression that Soto (1990) determined to be an explosion crater of the maar-type.
