英文摘要	Volcan Momotombo, Nicaragua is a basaltic to basaltic-andesite stratovolcano located along the active Central American Volcanic Arc. It last erupted in 1905. Seismic swarms have been occurring beneath Momotombo for the past year. A major seismic swarm, which included an M4.7 earthquake, began on November 24, 2015, and culminated in gas and ash eruptions beginning at 7:49 am (local time) on December 1, 2015. By the evening of December 1, Momotombo was in strombolian eruption with columns to ~1 km and lava flows flowing down the northern flank of the volcano. At this stage the Momotombo eruption appears to be characterized by both small-volume lava and small-volume tephra emissions. This RAPID funding will support a multi-disciplinary team that will travel to Nicaragua to collaborate with our INETER colleagues to: 1) install GPS instruments around the volcano and analyze existing GPS data; 2) install four broadband seismic instruments to study magma storage and migration beneath Momotombo; 3) make observations of the ongoing eruption to study the style of eruptive activity and collect tephra samples to investigate plume dynamics; 4) collect samples of tephra and lava flows for geochemical analyses; and 5) investigate precursory volcano and crustal deformation at Momomtombo using InSAR. This project leverages support from the NSF-funded COCONet project, the CEOS initiative, and existing infrastructure from previous NSF-funded projects led by members of this team.
