Ubinas volcano (Peru): new lava dome grows to 120 m diameter

The new lava dome with high-temperature degassing on 19 March (J. Acosta, Defensa Civil de Moquegua)
The new lava dome with high-temperature degassing on 19 March (J. Acosta, Defensa Civil de Moquegua)
The volcano's new lava dome continues to grow slowly within the crater. New field observations published yesterday in a detailed report showed that the lava dome is now approx. 120 m in diameter and has completely filled the inner pit left by the explosive activity in 2006 (as of 19 March). Visible glow (even in daylight) indicates very high temperatures.
No explosions have occurred since the vent-clearing explosion on 14 Feb, but the volcano emits a significant plume of steam, SO2 gas and sometimes dilute ash. On 21 and 23 March, the steam-gas-ash plume rose 1800 m above the crater.
On 25 March, light ash falls were reported in the towns of Querapi and Ubinas, as well as strong rumbling noises in distances up to 6 km SE.

Seismicity remains above background with frequent earthquake swarms related to internal fluid movements.
According to IGP, the intensity of the current activity overall is still low and probably continues for a while at similar levels, although explosions (caused, for instance, by trapped gasses under the lava dome) could occur at any time.

The volcano could be in the process of entering a new eruptive phase. Two small (likely phreatic) explosions occurred last Friday at 13:46 and 14:45 h local time (18:46 and 19:45 GMT), ejecting plumes of ash and steam rising approx. 1.5-2 km. A strong sulfur smell was noticed in up to 5 km distance. ... [details]
