Roundup of Global Volcanic Activity
Sakurajima (Kyushu, Japan): The volcano continues to produce small to moderate vulcanian explosions at rates of a few per day, typically.
Colima (Western Mexico): The volcano continues to produce intermittent explosions, but there might be something new in the making: weak, but continuous glow from the crater has appeared during the last night, something that hasn't been observed since the latest effusive eruptive phase in July last year. It could indicate that a new lava dome is about to appear. The next days or weeks will probably give a better answer. Washington VAAC reported that during 3-8 February ash plumes from Colima rose to altitudes of 4.9-6.7 km (16,000-22,000 ft) a.s.l. and drifted 75-140 km in multiple directions.
