Scars of landslides that merged together to form lahar on June 6, 1994
Photograph by R.L. Schuster onJuly 4, 1994

The brown scars of landslides merge above R?o Paez. Nearly all of the landslides orginated on slopes of >30°. Most began as shallow slips in water-saturated soil and liquefied immediately; heavy rains before the earthquake had saturated the steep hillsides. The slides typically were about 1-2 m thick. Near the earthquake epicenter, the landslides removed >50% of the vegetation.
