Atmospheric Effects (1980-1989)

All times are local (unless otherwise noted)

No large new volcanic layers appear to have been injected since the November 1985 eruption of Ruiz. Lidar data in September and October showed few remaining stratospheric volcanic aerosols. Satellite data suggest that eruption clouds ejected on 9 May at Banda Api and 29 July at Makian, both in Indonesia, may have penetrated the stratosphere. Small new layers were detected by lidar after the Banda Api eruption, but neither eruption appears to have had a significant long-term effect on the stratosphere.
