Roundup of Global Volcanic Activity
Suwanose-jima (Ryukyu Islands): After a period of relative calm since last October, a new phase of strombolian activity occurred this morning at the volcano.
Sinabung (Sumatra, Indonesia): The activity of the volcano seems to have picked up. Sinabung increases its activity after the big pyroclastic flow on 26 Feb which burned the remaining houses left from the previous damaged village (Simacem)…- this and the occurrence of highly hybrid tremors means there is deformation of the lava dome that grows continuously and increases the intensity of rock falls followed by pyroclastic flows.
Fuego (Guatemala): The activity of the volcano continued to increase into its 4th paroxysm (called “eruption” by local press) of 2016. Lava effusion rate increased gradually and continued to feed the lava flow on the eastern side into the Las Lajas ravine, where it reached approx 600 m length yesterday and started to produce small pyroclastic flows (by collapse of parts of the flow on the steep slope).
Pulsating lava fountains at the summit vents generated an steam and ash plume that rose 2-3 km above the volcano, reaching altitudes of 17-20,000 ft(5.2 – 6 km). The plume drifted southwest for up to 20 km before dissipating. Constant moderate to strong rumblings can be heard and felt in nearby areas.
Telica (Nicaragua): (1 Mar) A new eruption seems to be underway at the volcano. Bright glow has become visible from the crater since around midnight (local time). This probably indicates that a new eruptive fissure is opening up there, possibly erupting lava onto the crater floor.
Momotombo (Nicaragua): Two moderately strong explosions occurred during the past 24 hours at the volcano, covering the upper slopes of the cone with fresh lava bombs and producing ash plumes that rose approx 2 km. This followed a period of calmer activity that had lasted a few days.
Erta Ale (Danakil depression, Ethiopia): The level of the active lava lake in the volcano’s southern pit crater of the summit caldera has sunk a bit again after its last overflow in mid January, but remains highly agitated. Erta Ale is going down again to 5-7 Meters from the rim of the caldera, but the activity is getting very wild at this time and it was very hard to walk on the the recently crusted flow. The last flow went in every direction from the crater and covered the whole rim with fresh crust of gaseous basaltic pahoehoe lava.”
