| 15475 | 09 Aug 2020 @ 1313 | 09 Aug 2020 @ 1741 | JSJ | All closed intervals. Filmed. Perforated Cone eruptions today correlated with rises in Lone Star's water level. Somewhat deep-pitched sizzling sounds accompanied each Perforated Cone eruption, which involved spitting and spritzing from multiple small vents. |
