The level of seismicity remains low.\r\n\r\nIt remains possible for eruptive activity consisting of lava effusion, ash emissions or both to resume at any time without significant precursory seismic events. \r\n\r\nVeniaminof volcano is monitored with a local real-time seismic network, which will typically allow AVO to detect changes in unrest that may lead to a more significant explosive eruption. AVO combines seismic, infrasound, lightning, and satellite data for rapid detection of such events.","synopsis":"AVO Veniaminof YELLOW\/ADVISORY - No unusual activity detected in seismic or satellite data.","alertLevel":"ADVISORY","colorCode":"YELLOW","vName":"Veniaminof","vnum":"312070","lat":56.1979,"lng":-159.3931,"vUrl":"https:\/\/avo.alaska.edu\/activity\/Veniaminof.php","vImage":"https:\/\/avo.alaska.edu\/images\/dbimages\/display\/1102615671_37_3.jpg","region":"Alaska Peninsula","sectionId":"DOI-USGS-AVO-2019-02-24T12:03:58-09:00"}]}
