Momotombo , Nicaragua :
The Nicaraguan Institute of Territorial Studies (INETER) reported that on Tuesday afternoon, there were 18 micro-earthquakes under the volcano Momotombo. All these events were less than 2.5 degrees magnitude on the Richter scale.
The INETER explained that microseisms under the Momotombo volcano , 1,297 meters high, which is located at the northern end of Lake Managua or Xolotlán were recorded from 1:00 p.m. to 1:14 p.m..
Armando Saballos, volcanologist of INETER, said that the movement had very little energy and were associated with a small injection of magma under the volcano, as a result of eruptive activity he presented in December 2015.
« From April until now, it was almost nothing extraordinary happened on the volcano. With the proceeds from this seismic swarm there was a small gas explosion, » said Saballos.
The National Prevention System, treatment and mitigation of disasters (SINAPRED) said they are aware of the situation and asked the residents of areas near the Momotombo, to remain calm.
The authorities have asked to not approach the volcano.
Today August 30 the Momotombo volcano recorded a gas explosion. It was also noted that from 1:00 p.m. to 1:14 p.m., the seismic network detected 18 microseisms, the biggest was magnitude 2.5 M, all microseisms were located under the volcano.
Microseisms were associated with the injection of a magma flow beneath the volcano.
The Ineter continuously monitors the volcano and report timely on upcoming changes.

Bárðarbunga , Iceland :
A 3.8 magnitude earthquake was picked up by sensors 5.7 km (35 miles) northeast of Bárðarbunga volcano in Vatnajökull glacier in the northern highlands at approximately 1:30 pm today. Bárðarbunga caused the 2014-2015 Holuhraun eruption.
Seismologist Martin Hensch at the Icelandic Met Office told mbl.is that between ten and 15 aftershocks followed the quake. He stated this is likely a case of movements in the edge of the caldera but not movements of magma.
Meanwhile, the seismic activity in Katla volcano in South Iceland has calmed down. The last earthquake to be recorded there, as part of the swarm which began the night before yesterday, hit early this morning. The most powerful quakes measured 4.5 and 4.6 magnitude.
Today 30 AUgust at 13:33 an earthquake of magnitude 3.8 occurred at the northern rim of the Bárðarbunga caldera.
An earthquake of magnitude 3.4 was detected just north of Grindavík at 17:51 and was felt by locals.

Klyuchevskoy , Kamchatka :
56.06 N, 160.64 E;
Elevation 15580 ft (4750 m)
Aviation Color Code is ORANGE
Explosive-effusive eruption of the volcano continues. Ash explosions up to 26,240-32,800 ft (8-10 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.
Explosive-effusive eruption of the volcano continues: there are bursts of volcanic bombs above the summit crater and above the cinder cone into Apakhonchich chute, and strong gas-steam activity of two volcanic centers with emission of different amounts of ash, and the effusing of lava flows along Apakhonchich chute at the south-eastern flank and south-west flank of the volcano. On 30 August, the KVERT reported explosions of ash at 0:45 and 2:49, which amounted respectively to 16,400 ft (5000 m), and 14,760 to 16,400 ft (4500-5000 m). According to satellite data by KVERT, a large bright thermal anomaly was observed in the area of the volcano all week.

Wind: 0 kmh
Persistence of low white fumarole at a height of 4100 meters (13,451pies) which is dispersed to the West and Southwest. 15 low to moderate explosions were reported, emitting a gray column to a height of approximately 4300-4500 m. (14.107 -14,763pies) that traveled 8 km to the south and the southwest of the volcano.
Explosions with incandescent pulses stood at a height of 150-200 meters above the crater, creating small avalanches on the edge of the crater and to the Canyon Taniluyá. The explosions were accompanied by low rumbles and materials falls.
