At Nevado del Ruiz, an emission of ash and associated tremor was recorded on July 26 at 12:50 pm local, starting from the Arenas crater.

The alert level remains Amarillo, indicating an instability characterized by changes in seismicity, and gas / ash emissions.

On July 16 late in the day, the Colombian Geological Service technicians have collected the ashes from the Nevado del Ruiz, and scattered northwest of the volcano, ample on the city of Manizales.

Analyses of ashes were carried out by the Observatory of Manizales: In binocular, ash has a fine to medium grain size; on the mineralogical level, it is characterized by fresh lithic fragments, pyroxene and plagioclase crystals, and a small amount of volcanic glass.

At Kilauea's, the lava flow 61G remains active southeast of Pu'u O'o on the coastal plain .

Friday noon, the flow was at 730 meters from the costal road Relief and 870 meters from the ocean, with a progression of just 60 meters from the 12 juillet. The most intense activity area is located near the base of the Pali and extends over 1.3 kilometers from it.
