Lascar Volcano -- bottom center of the view (arrow) erupted violently in April 1993. Its primary ash cloud was dispersed towards the SE on the day of the eruption. These views were taken ten days later on May 4th. Light winds remobilize the ash and sweep it towards the ENE. A time sequence illustrates the importance of surface heating by the sun in generating local winds. The sequence spans 3 hours starting around 10h30 local time. The view above, taken near noon, shows three dust palls (center, center-right, right), starting well east of Lascar Volcano (cloud along the top of the view marks the lowlands of northern Argentina, indicating that the high plains lay above cloud level on this day). The view overleaf (STS055-102-076) was taken at ~13h30 and shows the dust event in full bloom, dust plumes stretching out over the lowland cloud deck (extreme right).
