Bramble Airport South end of runway around 20:00 hrs. The low clouds offered only a glimpse of flow coming from the dome. At one time three separate channels appeared, merging quickly into one flow. The material rushed down the dome. At times flowing streams of material and other times huge balls of material rolling in the stream then disappearing into the valley. The next day the flow would reach the sea. The glow would pulse in relation to the activity and the density of the clouds. Thunder rumbled for an hour as the event proceeded. Short loud bursts of noise could be heard over the crashing waves at the south end of the runway.

Ashfall. Picture taken from Old Towne looking south. Under the ash cloud is Plymouth. The hillside is known as Garibaldi Hill The cloud of ash produced a directional light such as one would experience during a solar eclipse. The bright colours of the tropics contrasted by the backdrop of black and gray ash . The light became very directional and hastened the short twilight of the tropics.

Ash fall heading south. This ash fall fell in the St. Patrick's area. The deposits were over 8 inches and the ash was a slick black ash. This was the first major ash fall in this area. This photo was taken from Old Towne looking southwest. The western side shows the pyroclastic flow which went down the Tar Valley to the sea to start the building of the peninsula.

The eruption begins. This photo was taken inside the evacuation zone just outside of Plymouth toward Cork Hill. The eruption had just begun and a heavy warm black rain has begun to fall. On the south side of the island near The Great Alps Falls small pellets of ash in the water began to get larger and the water became a dark gray in colour. 50 minutes later the ash began to fall.

About two hours into the ash fall this photo was taken from Old Towne looking to the South East toward Fox's Bay. The main ash fall was over the evacuated town of Plymouth.


July 27, 1996
This was the day after the heavy ash fall on Plymouth. The ash top was much higher this day. The direction was not typical as the cloud headed south rather that its normal eastward track.

This set was taken from the hillside in Old Towne. This set of photos highlight the ash as it rises from the Tar Valley on its way to the sea.
