Ongoing rainfall has been causing a number of mud flows (lahars) in the rivers draining from Santiaguito, including Samala, San Isidro and Tambor.
A first large hot lahar descended the Nima I river bed yesterday. The sulfur-smelling mud flow was about 25 m wide and 3 m deep, carrying blocks of up to 50 cm in diameter and pieces of tree trunks and branches of up to 2 m. On its passage near the observatory, it made the ground vibrate. The lahar drained into the Samala river.
