Seismic signal last night / this morning from Pacaya (PCG station, INSIVUMEH)
Popocatépetl (México): actividad ha seguido disminuyendo y no ha habido ningún nuevas explosiones importantes. El número de emisiones de vapor de gas (que a veces contienen también pequeñas cantidades de ceniza) ha disminuido de un promedio de 5 por hora a solamente 2 por hora ayer por la noche. Pacaya (Guatemala): como la señal sísmica sugerida, un fuerte incremento en la actividad se produjo el ayer por la tarde y culminó en la efusión de un flujo de lava desde el cráter Mackenney, que duró aproximadamente dos horas.La actividad volvió a la actividad estromboliana suave luego, con proyecciones de alcanzar sobre 200 m de altura y ceniza plumas llegando a 400 m por encima del cráter....
