| Comments: | unusual eruption of Echinus was observed at 2:28 pm. At 2:13 water overflowed ridge & the pool boiled strongly as if it were going to erupt. Then the water level dropped & water poured back in crater. Following about 4 min the water level started to rise again. After the eruption the level dropped much lower than usual. |
