Ecuador Volcano Eruption On 2014-04-11 at 04:23:54 [UTC] Event: Volcano Eruption Location: Ecuador Andes Tungurahua Volcano An explosion occurred yesterday morning at 02:28 local time and was followed by a new phase of lava fountaining and strombolian explosions accompanied by continuous tremor. The detonation sounds were heard like cannon-shots in all directions away from the volcano including the city of Ambato and the volcano observatory. Incandescent material descended the flanks up to 2 km distance. Ash falls were reported in the towns of Manzano and Cahuaji Choglontus. A peak of activity was noted at about 5 am. After 9 am, intensity decreased, but gained strength again at 13:00. Some of the explosions were described as very strong. The explosive activity remained very strong all the afternoon until the evening, our reader Bastien Poux reported. This morning the volcano was in the clouds. The observatory measured a significant increase in SO2 emissions: 1769 tons on 6 April, 4176 tons on 7 April and 9946 tons on 8 April. This is consistent with a new batch of magma that has been rising into the currently open-conduit system of the volcano. Deformation measurements also suggest that new magma injections have been taking place. Under these circumstances, the most likely scenario is that similar moderate-high levels of volcanic activity continue for the coming days, while the new magma batch is reaching the vent. If activity increases further, pyroclastic flows could be generated, threatening areas at the feet of the volcano, in particular valleys radiating from it.
