Telica, one of the most active volcanoes in Nicaragua, is a group of overlapping cones and craters on a broad NW line. The most prominent vent is a 700 m wide and 120 m deep double crater at the summit. Its southern summit crater has been the source of Telica's recent eruptions.
The older Santa Clara vent at the SW end of the edifice erupted in 16th century and is now covered with vegetation. Another vent El Liston, immediately SE of Telica, is another volcanic edifice with several nested craters.
Fumaroles and boiling mudpots are found at Hervideros de San Jacinto, SE of Telica. This prominent geothermal area is popular among tourists and the site of nearby geothermal exploration.
Seismic recording from Telica this morning (TELN station, INETER)
Seismic recording from Telica 15 May (TELN station, INETER)
Seismic activity has returned (for now) to relatively low levels today. This follows many small earthquake swarms that occurred during the past week. [read all]
Current seismogram from Telica volcano (TELN station INETER)
Seismic activity has decreased a bit in energy recently. Although the frequency of earthquakes has slowed down, the quakes, still above background levels, are now of higher magnitude.
Depth vs time of recent quakes under Telica volcano
The earthquake swarm continues, with increasingly large volcanic quakes (up to magnitude 3), many of which are showing up on INTETER's country-wide earthquake list as well. ...more
However, there is still no official report about anything unusual going on, which suggests that the swarm is not regarded as alarming. [less]
Telica seismogram this morning (TELN station INETER)
The seismic swarm continues with again increased strength. Especially the amplitudes of (shallow) volcanic quakes have been bigger than before. This volcano remains a good candidate for a next eruption in Central America.
Current seismogram from Telica volcano (TELN station INETER)
Seismicity has remained high. INETER has not (yet) published anything about unusual activity at the volcano, which suggests that they don't expect any eruption anytime soon.

Depth vs time of quakes under Telica volcano
The earthquake swarm still continues and appears to show a slow trend towards increasing magnitude earthquakes including a magnitude 3 event two days ago.
Telica seismogram this morning (TELN station INETER)
The earthquake swarm, presumably caused by a magmatic intrusion at shallow depth, still continues with hundreds of tiny quakes up to about magnitude 2 each day.
Earthquake activity in the ongoing seismic swarm remains very high and there have been a few magnitude 2+ quakes at shallow depths today as well. ...more
There has not been any report from INETER yet. [less]
Telica seismogram this morning (TELN station INETER)
The seismic swarm continues with no changes. Hundreds of tiny quakes up to magnitudes around 2 have been occurring for the past days, but no reports have become available (so far).
The seismic swarm at the volcano continues, with many small tremors registered beneath the eastern sector of the volcano. There has not been any apparent surface activity reported (so far).

Depth vs time of quakes under Telica volcano
The seismic swarm continues to increase in intensity. The earthquakes are still small (below magnitude 3), but some already show up on INETERS country-wide earthquake list, and are mostly located 5-10 km east of the volcano. ...more
No updates about unusal activity have been posted by INETER, so it is likely that this is (so far) only an intrusion at some depth with no significant surface activity. [less]
The seismic swarm has intensified a bit. Some of the quakes are now listed by INETER on their earthquake list. The largest is apparently a magnitude 2 earthquake at 1.2 km depth a few km to the east of the summit.

Telica seismogram - current (TELN station INETER)
The seismic swarm continued until this morning, then waned a bit, but has now resumed with increased apparent strength (perhaps because quakes are now nearer to the surface). ...more
In contrast to Telica, the other 2 Nicaraguan volcanoes San Cristobal and Masaya continue to be quiet. [less]
