Map of today’s active volcanoes

Campi Flegrei (Phlegrean Fields) (Italy): After the water in the Averno crater lake turned red last week because of an unusually strong algae bloom, stretches of the sea in the Gulf of Pozzuoli also turned red recently, presumably from the same phenomenon.
Such algae blooms of the Averno lake usually happen in winter, when deep water is warmer than at the surface and rises along with algae that can multiply explosively. However, this year’s algae bloom, especially its extension into the adjacent open sea seems to be much stronger than what residents can recollect from recent memory. Many are worried whether there is a connection with the increased seismic and degassing activity of the caldera volcano:

Since the status of the Campi Flegrei has been on a first level of increased unrest for a while, many residents are concerned about a possible connection. A suspicion voiced is that the algae bloom in the sea could be due to an increased heat flow at the sea floor, as a result of increased volcanic degassing.

São Jorge (Azores Islands, Portugal): ) The seismic swarm under the island’s northwestern rift zone has decreased a lot during the past days, but it is still ongoing at lower levels.
Weak inflation also continued to be registered, which is why the official alert level remains at the second highest level of V4.

São Jorge (Azores) seismic activity continues above normal levels. Although it has decreased in hourly frequency and magnitude, it is still ongoing. Since 19 March at least 226 events were felt by the population. For updates follow @PROCIVazores and CIVISA https://t.co/nTI0gn2FPH pic.twitter.com/VrujkrVfjF

Kadovar (Northeast of New Guinea): ) Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 5000 ft (1500 m) altitude or flight level 050 and is moving at 15 kts in SE direction.
The full report is as follows: DISCRETE VA EMISSIONS TO FL050 EXT TO SE OBS VA DTG:08/0130Z to 5000 ft (1500 m)

Semeru (East Java, Indonesia): ) Volcanic Ash Advisory Center Darwin (VAAC) issued the following report: VA REPORTED TO FL150 AT 07/2248Z OBS VA DTG:07/2248Z

Dukono (Halmahera): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 7000 ft (2100 m) altitude or flight level 070 and is moving at 20 kts in NE direction.
The full report is as follows: CONTINUOUS VA EMISSIONS TO FL070 EXT TO NE AT 08/0850Z to 7000 ft (2100 m)

Kilauea (Hawai’i): ) The lava lake has dropped, but remains active. This follows the usual pattern of recent deflation at the summit of the volcano and will likely revert to inflation and rising lava lake levels in the near future.
The volcano observatory reported: “The summit eruption of Kīlauea Volcano, within Halemaʻumaʻu crater, continues at this time. The level of the active lava lake within Halema‘uma‘u has dropped by several meters since 6:00 p.m. yesterday, in association with summit deflation and a decline in volcanic tremor.

However, the lake surface has continued to circulate today. This activity resembles that of other summit deflationary periods in recent weeks, so lava will likely be on the surface of the active lava lake this evening.”

Popocatépetl (Central Mexico): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 20000 ft (6100 m) altitude or flight level 200 .
The full report is as follows: VA EMS OBS to 20000 ft (6100 m)

Fuego (Guatemala): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 15000 ft (4600 m) altitude or flight level 150 and is moving at 5 kts in W direction.
The full report is as follows: ONGOING VA EMS to 15000 ft (4600 m)

Poas (Costa Rica): ) An eruption occurred yesterday (7 April) morning at 2.42 a.m. local time from the volcano’s crater northern area. The event lasted about 3 minutes and generated a steam plume that rose 500 m from the crater to approx. 3200 m altitude.
There was apparently no warning for the eruption, which came without detectable precursors, such as increases seismic activity, an increase in temperature at the fumaroles or other geophysical changes. During other eruptions of Poás, the temperature at the northern crater rim’s fumaroles often had been seen increasing from 100 to 900°C, volcanologist Javier Pacheco from Costa Rica’s monitoring agency OVSICORI-UNA explained in an interview with La Nación. This had not been the case yesterday. As the eruption seems to have not involved any new magma, but almost purely ejected steam, it was likely a phreatic (steam-driven) explosion.

It is actually rather typical that such phreatic explosions occur with little or no warning at an active volcano: Fluids, water and gasses, contained in the subsurface system of cracks and cavities normally form a circulating system that allows heat and excess gasses that can no longer be stored in solution to be transferred to the surface, where degassing takes place, often in the form of fumaroles or hot crater lakes.

Nevado del Ruiz (Colombia): ) Volcanic Ash Advisory Center Washington (VAAC) issued the following report: NO VA OBS

Sangay (Ecuador): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 21000 ft (6400 m) altitude or flight level 210 .
The full report is as follows: ONGOING VA EMS to 21000 ft (6400 m)

Reventador (Ecuador): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 15000 ft (4600 m) altitude or flight level 150 .
The full report is as follows: ONGOING VA EMS to 15000 ft (4600 m)

Sabancaya (Peru): Volcanic Ash Advisory Center Buenos Aires (VAAC) issued the following report: continuous ash emissions
