Morning Update
0715H 20 December, 1995


Seven long period earthquakes occurred overnight. There were no locateable volcano-tectonic earthquakes. Small long-period earthquakes are still being recorded by the Gages seismic station, but they are not very frequent. Flash flooding in Fort Ghaut and Aymers Ghaut late yesterday afternoon was recorded on the Gages seismometer between 17:00 and 19:00.

Processing of yesterday's EDM data was completed last night. The only change was in the line from Amersham to the reflector on Gages Wall- this line lengthened by 4 cm.

Visual observations were made early this morning from Whites and Long Ground. Glowing rock was seen on the north side of the crater area. At 03:40 Police Officers manning the airport checkpoint reported seeing glowing material falling from Castle Peak into the upper Tar River area. This was probably a small pyroclastic flow. The volcano is clear of cloud for the first time since Sunday, so observation of the crater area is now underway from the helicopter.
