Volcanos

Roundup of Global Volcanic Activity:

Chirpoi (Kurile Islands, Russia): SVERT maintains yellow alert level, but could not obtain satellite data during the past week to determine whether activity continued.

Ketoi (Kurile Islands, Russia): Steam-gas emissions and a thermal anomaly continue to be detected from satellite data when atmospheric conditions allow.

Chirinkotan (Northern Kuriles): A steam and gas plume remains visible sometimes on satellite data, suggesting that activity (lava effusion?) continues.

Sakurajima (Kyushu, Japan): The volcano has been stepping up its activity again over the past 2 days. Yesterday alone, at least 6 explosions were registered by VAAC Tokyo, with plumes reaching up to 11,000 ft (3,4 km) altitude.

Popocatépetl (Central Mexico): Activity has been stable with little changes. The rate of emissions decreased yesterday to about 1-2 per hour, but some small to moderate explosions still occur from time to time, producing ash plumes up to about 1.5 km height.
