Czechoslovakian Earthquake Victims, Llanganuco. A 15-man Czech expedition attempted the south face of Huandoy in May. On May 18, one of their number, Ivan Bortel, slipped and fell 100 feet down a brook bed while descending unroped on easy terrain and was killed instantly. The party gave up its original objective and after climbing Pisco, was turning to the north peak of Huascarán. All were in their Base Camp, which was located between the upper and lower Llanganuco lakes, when they were overwhelmed by a colossal avalanche which fell from the north side of the north peak of Huascarán triggered by the earthquake of May 31. (This was not the same avalanche which swept Yungay away, as has been erroneously reported.) The victims were Arnošt Cerník, leader, Valerian Karoušek, Vilém Heckel, Jirí Rasl, Jirí Jech, Svatopluk Ulvr, Miloš Matras, Jaroslav Krecbach, Milan Cerný, Ladislav Mejsnar, Bohumil Nejedlo, Milan Náhlovský, Zdenék Novotný, Václav Urban and the Chilean Pedro Núñez.
