A pyroclastic flow descends the quebrada of Tumbre, north of Lascar at 0930 hours on April 20, 1993.  A plinian eruption April 18-20 was the largest from Láscar in historical time.  Pyroclastic flows containing white pumice, dark scoria, compositionally banded pumice, and dense blocks from the summit lava dome traveled as far as 8.5 km down the NW, NE, and SE flanks.
