Volcanos

Roundup of Global Volcanic Activity

Colima (Western Mexico): The volcano continues to produce sometimes strong vulcanian-type explosions that seem to have picked up in strength over the past days. An eruption at 03:08 am local time produced fountaining of lava several hundred meters high and appears to have caused a small pyroclastic flow.

Karymsky (Kamchatka): Intermittent strombolian to vulcanian explosions continue to occur at the volcano. Occasionally, such as this morning, the resulting typically smaller ash plumes are large enough to be reported in Tokyo VAAC's volcanic ash advisories. Karymsky is one of the world's few volcanoes having been in persistent activity for centuries.

Zhupanovsky (Kamchatka, Russia): A relatively large ash emission from the volcano was reported this morning by Tokyo VAAC. Based on MTSAT satellite imagery, an ash plume rose to estimated 27,000 ft (8 km) altitude and extended east.

Dukono (Halmahera): An ash emission this morning was observed on satellite imagery (Darwin VAAC).

Villarrica (Central Chile): Weak intermittent strombolian activity at the summit crater and occasional small ash emissions continue. In its latest report from yesterday, SERNAGEOMIN mentioned a decrease in tremor and observed emissions. An exclusion zone of 5 km radius around the crater is in place as the activity can increase abruptly at any time.
