The Lewotobi Laki-Laki volcano on the Indonesian island of Flores remains highly active following eruptions on Saturday and Sunday (April 26-27) that spewed ash high clouds high into the sky.
According to Indonesia's Centre for Volcanology and Geological Hazard Mitigation, the ash column from both eruptions reached a height of 4,000m.
Witness accounts said the latest eruption was accompanied by a loud bang.
Authorities warned residents and visitors to stay at least 6km away from the centre of Lewotobi Laki-Laki.
A restive volcano in the central Philippines spewed a column of ash as high as 4.5km (2.8 miles) into the sky on Monday morning, prompting authorities to raise the alert level at Mount Bulusan and warn residents to stay out of a 4km danger zone.
The Philippine Institute of Volcanology and Seismology (Phivolcs) raised Bulusan's alert status from 0 to 1 on its five-level scale, signalling low-level volcanic unrest and warning of possible phreatic eruptions.
Before the eruption, which occurred between 4.36am and 5am on Monday, the institute had recorded 53 volcanic earthquakes over a 24-hour period and local officials reported rumbling sounds.
Volcanic ashfall from an eruption of Bezymianny Volcano in Russia's far eastern Kamchatka Peninsula has blanketed three villages in the Milkovo District, local emergency services said on Thursday.
Volcanic ash is currently falling in three villages from emissions from Bezymianny Volcano, the regional branch of the Russian Ministry of Emergency Situations said on its Telegram channel, News.Az reports, citing Xinhua.
"While the livelihoods of residents have not been disrupted, emergency services strongly advise people to stay indoors unless absolutely necessary," it added.
The Far Eastern Branch of the Institute of Volcanology and Seismology of the Russian Academy of Sciences has modeled the projected path of the ash cloud. Their data indicate that volcanic particles are drifting toward another settlement, the village of Kozyrevsk in the Ust-Kamchatsky District.
The Bezymyanny volcano has emitted an ash column for the fifth time in 24 hours, with the latest plume rising 11 km above sea level. As a result, the aviation color code has been raised to "red," meaning a significant threat to all types of aircraft.
Bezymianny Volcano is situated about 40 km from the village of Klyuchi and 350 km from the regional capital city of Petropavlovsk-Kamchatsky.
The Poás volcano, one of Costa Rica's most popular tourist attractions, erupted suddenly on Monday, arousing the interest of many social media users and amateur volcanologists.

New eruption at Mount Etna in Italy
Mt. Etna, Europe's tallest active volcano, erupted again Friday evening on the Italian island of Sicily, sending ash and lava from its southeastern crater through early Saturday.
The eruption began around 7 pm (1700GMT) at the southeastern crater, located at an altitude of 2,900 meters (9,514 feet), according to local media reports. The lava split into three flows moving southeast down the slope, Italian daily La Stampa reported.
Residents said rumbling from the explosion was heard clearly in nearby villages.
Mount Marapi, located in Agam and Tanah Datar regencies, West Sumatra, erupted again on Saturday, April 19, 2025, spewing volcanic ash up to 1,000 meters above the peak. The eruption occurred at 06:11 AM WIB (West Indonesia Time), with a dense gray ash column leaning towards the south.
According to the report from the Center for Volcanology and Geological Hazard Mitigation (PVMBG), the 3,891-meter-high mountain's seismic activity above sea level was recorded with a maximum amplitude of 30.3 millimeters and lasted 42 seconds.
"This phenomenon is consistent with the fluctuating activity trend of Marapi," said Ahmad Rifandi, the Mount Marapi Volcano Post Officer, in his official statement on April 19, 2025. The activity status of Mount Marapi is still at Level II or Alert.

Mount Semeru in Lumajang, East Java, experienced six eruptions between early Thursday and noon, April 17, 2025, with the highest volcanic ash column reaching 1,000 meters above the summit during the 9:17 AM local time eruption.
"The ash column was observed to be white to gray, thick, and drifting east and southeast," reported Sigit Rian Alfian, an officer at the Mount Semeru Volcano Observation Post in Mount Sawur, Lumajang Regency, in his written report on Thursday.
Sigit noted that the 9:17 AM eruption registered on the seismogram with a maximum amplitude of 22 mm and lasted approximately 1 minute and 57 seconds. Over the preceding 24 hours, seismic data recorded 61 eruption tremors (10-22 mm amplitude, 51-154 second duration), 9 gust tremors (3-8 mm amplitude, 27-64 second duration), 1 harmonic tremor (8 mm amplitude, 134 second duration), and 3 volcanic tremors (4-25 mm amplitude, S-P 2-3 seconds, 15-22 second duration).
Mount Lewotobi, located in Indonesia's East Nusa Tenggara province, erupted on Wednesday, triggering a flight warning and safety advisories, the Volcanology and Geological Disaster Mitigation Centre said. The eruption released a column of ash up to 3,500 metres into the sky, and the thick gray cloud moved westward and northwestward of the crater.
To mitigate risks posed by the volcanic ash, a Volcano Observatory Notice for Aviation has been issued at the orange level, the second-highest warning, banning planes from flying below 5,000 metres in the vicinity of Mount Lewotobi. Aircraft should also exercise caution regarding the presence of volcanic ash, which can disturb their flights. To protect the residents living on the slope of the volcano from the risks of hot clouds and volcanic materials, the centre has issued safety advisories, Xinhua news agency reported. The residents, tourists, and visitors should not engage in any activities within a radius of six km from the volcano.
A thick cloud of smoke poured out of the Poas Volcano, in Costa Rica's Alajuela province, on Tuesday, April 8, during the crater's latest eruption.
During a press conference, Alejandro Picado, President of the National Emergency Commission, announced the Poas Volcano National Park and Bajos del Toro were on orange alert due to the impact of gases and ash fall, while several surrounding areas, including Alajuela, remained on green alert.
Footage captured by the Red Sismologica Nacional Universidad de Costa Rica (RSN-UCR)'s live camera shows a thick cloud of ash rising above the volcano on Tuesday morning.
"More energetic episodes were observed early this morning, around 2:20 am, and another between 6:18 and 6:30 am, which reached over 1,000 meters in height," the RSN-UCR wrote to X. Credit: Red Sismologica Nacional Universidad de Costa Rica via Storyful
