Map of earthquakes greater than magnitude 3.8 from May 10, 2018 to October 29, 2018. Purple and blue earthquakes occurred early in the crisis while yellow and red earthquakes occurred months later.  The average horizontal error on the location is approximately 15 km.  Thus, we cannot see an orientation of the earthquakes in one of the two swarm regions.

La Palma (Canary Islands (Spain)): A relatively strong swarm of earthquakes occurred under the La Cumbre volcano on the island of La Palma yesterday (December 24, 2020).
A total of 79 small earthquakes with a magnitude between 1 and 2.2 were detected yesterday, most at depths of about 25 to 30 km below the southwestern part of the island, 15 km south-east of Los Llanos de Aridane. Many are located under the mostly submerged volcanic ridge of Cumbre Vieja, which last erupted in 1971. It appears the swarm has already ended (unless more data is released later by the Spanish Geophysical Institute. ).

Kilauea (Hawaii): The new eruption of the world’s most active volcano continues without significant change, but at breakneck speed as the new lava lake grows and is about to flood its vents.
According to the USGS Hawaiian Volcanoes Observatory (HVO), the 176m-deep lava lake at 7 a.m. local time this morning. The lake inside Halema’uma’u crater is fed by two vents on the north and northwest sides of the crater. The fresh magma rising to the surface carries with it a lot of SO2 gas, released into the atmosphere in the form of a dense plume.

Popocatépetl (Central Mexico): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned of a plume of volcanic ash that rose to an estimated elevation of 20,000 feet (6,100 m) or flight level 200.
The full report is as follows: OCNL VA EMS. up to 20,000 ft (6,100 m)

Sabancaya (Peru): The Volcanic Ash Advisory Center Buenos Aires (VAAC) has published the following report: SPORADIC FOOD SHOW

Hudson (southern Chile and Argentina): The volcanic alert level of the volcano has been increased to “yellow”, because increased seismicity was recorded on December 22 characterized by 2 swarms of volcano-tectonic earthquakes of greater magnitude M 2.9 located 4.7 km ESE of the center of the caldera at 4.6 km depth.
In the category of hybrid volcano-tectonic earthquakes, the seismic instruments recorded five events, the largest of which reached magnitude M 3.1 located at 4 km ESE at 4.3 km depth.

Island of Mayotte (France, Western Indian Ocean): In May 2019, a new volcano was discovered 50 km off the east coast of Mayotte by temporal comparison of bathymetric data. It lies on the seabed at a depth of 3500 m. It is 820 m high and the estimated erupting volume is greater than 5 km3.
Indeed, since May 2018, seismic activity has affected Mayotte. The earthquakes off Mayotte are grouped into two main areas: the main one is located between 5 and 15 km east of Petite Terre and appeared later, at the end of August 2018, while the secondary, which appeared in early May, was ‘about 25 km east of Petite Terre and 25 to 50 km deep. The most significant earthquakes are in the secondary swarm area, including a Mw5.9 earthquake that occurred on May 15, 2018. Since July 2018, the number of earthquakes has decreased slightly, but seismicity continues steadily at low to moderate magnitudes.
