| Comments: | 1253 - huge above the cone surge from Upper Mortar with a brief drop out of sight and then it was back along with all F & M vents at 1254. First pause was at 1310. Restarts, all approximate... 1312-1313, 1315-1318, 1319-1325, & 1328-1335 (this last a mix of mostly steam with some water that stayed inside the vent). East Vent ejected several good sized rocks during the eruption. |
