Activity Bulletin February 26, 2016
Since 12:00 yesterday until 12:00 today, the Momotombo volcano recorded 4 new explosions, the strongest recorded at 9:21 p.m. yesterday, who issued incandescent materials were deposited on the flanks Northeast, East and Southeast of the volcano.
The ashes expelled totaled at least 1,000 meters above the crater. The latest explosion occurred at 9:59 am, which raised a small column of gas and ash about 300 meters above the crater.
So far, a total of 60 explosions were recorded on the Momotombo since he began his recent activity, which occur more frequently in recent days, but with less intensity that at the beginning of this month.
Seismic amplitude in real time (RSAM) of Momotombo is low to moderate, with values between 55 and 130 units.
In the last 24 hours, 4 earthquakes were recorded near and inside the caldera of the Masaya Volcano, with magnitudes between M1,2 and M1,7.
These small earthquakes are characteristic of the volcanic activity of the Masaya volcano.
The activity of the lava lake in the crater Santiago continues, and the process of enlargement of the mouth in the bottom of the crater, where lava lake is observed.
The volcanic tremor of the volcano remains high, and seismic amplitude in real time (RSAM) is high to very high, between 250 and 1,100 units.
The glow remains in the crater of Telica, where the presence of magma to the surface is observed.
The micro-seismic activity remains high due to magmatic surface activity and small gas explosions that occur inside the crater.
Seismic amplitude in real time (RSAM) is low to moderate, with values between 60 and 140 units.
