The eruption record at Lascar becomes more irregular after the 1993 eruption. During April 1993, a new lava dome formed in the crater, reaching a diameter of . It started to shrink again by May. On 17 December 1993, another explosion created an eruption column high. By 28 December, the dome had subsided completely in the centre, leaving only its margins. Subsequently, a number of fumaroles were active around the crater. Explosive eruptions, accompanied by the formation of eruption columns reaching heights of several kilometres, sometimes leading to ash fall in Jujuy, Argentina, occurred on 27 February 1994; in July 1994, November 1994, and March 1995; and on 10 May, 20 July and 18 October 1996. During the July 1995 eruption, subsidence was noted on satellite images of the inside of the central crater. The collapse structures during this activity were larger than those noted in previous activity, possibly because the April 1993 eruption had emptied part of the system. Otherwise, activity between 1993 and 2000 was not accompanied by deformation of the edifice.
