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

Earth's first crust composition discovery rewrites geological timeline

Researchers have made a breakthrough discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began.

A study published today in Nature reveals that Earth's first crust, formed about 4.5 billion years ago, probably had chemical features remarkably like today's continental crust.

This suggests the distinctive chemical signature of our continents was established at the very beginning of Earth's history.

Professor Emeritus Simon Turner from the Faculty of Science and Engineering at Macquarie University led the study, which included researchers from around Australia and the UK and France.

"This discovery has major implications for how we think about Earth's earliest history," says Professor Turner.

"Scientists have long thought that tectonic plates needed to dive beneath each other to create the chemical fingerprint we see in continents.

"Our research shows this fingerprint existed in Earth's very first crust, the protocrust - meaning those theories need to be reconsidered."

The fallout from the explosion on Negros island has raised concerns for nearby residents' health.
One of the Philippines' most active volcanoes erupted on Tuesday, sending ash up to 4,000 metres into the sky.

The explosion of Mount Kanlaon on central Negros island, one of the country's 24 most active volcanoes, has raised health concerns due to ashfall that hit nearby villages. However, there have been no immediate reports of casualties.

The 2,435-metre volcano's previous eruption last October sent hundreds of villagers fleeing to emergency shelters.

On April 5, 2025, Japan's formidable Sakurajima volcano unleashed a colossal eruption, sending shockwaves through Kyushu's Kagoshima Prefecture.

The eruption propelled a massive plume of ash and smoke into the sky, turning day into night and blanketing the surrounding areas in volcanic debris. Fiery lava cascaded down the slopes, illuminating the darkened skies with an ominous glow.

The Japan Meteorological Agency swiftly raised the eruption alert to its highest level, urging residents within a 3-kilometer radius to evacuate immediately.

This explosive event serves as a stark reminder of Sakurajima's volatile power and the ever-present dance between humanity and nature's raw fury.

A lava fountain was visible at Hawaii's Kilauea volcano during episode 16 of its latest eruption on April 1.

Footage captured by Chenay Noelani Borja shows lava shooting high into the air on Tuesday.

According to the US Geological Survey (USGS), lava fountains reached heights of 600 to 700 feet.

Kilauea's current eruption began on December 23, 2024, with each episode lasting anywhere from 13 hours to 8 days, the USGS said.

Officials reported that the 16th episode ended on Wednesday, April 2.

"Volcanoes in both Hawaii and Iceland, the Earth's two largest hotspots, are erupting today. Happy April Fools' Day! And they actually are erupting, no fooling!" the USGS wrote on X on Tuesday.

Mount Etna, the active volcano in southern Italy, reportedly erupted once more, releasing ash and lava.

Volcanic activity at the southeast crater of Mount Etna, at 3,357 meters (11,014 feet) in height, continued from Wednesday night to Thursday night, according to local sources, News.Az reports, citing Anadolu Agency.

The Italian National Institute of Geophysics and Volcanology (INGV) confirmed the activity.

Due to the ash clouds, INGV issued a red code warning for airplanes passing through the region, according to local media reports.

Mount Etna is one of the world's most active volcanoes, with an almost constant state of activity. The last time it erupted significantly was on Nov. 13-16.
