🌋📽️ This animation shows the sulfur emissions generated by the eruption of the Ethiopian volcano Hayli Gubbi. The data represents the values of Total column volcanic sulphur dioxide using CAMS data, with the plume extending from the African continent to India. #CopernicusEU

The ash cloud from the erupting Hayli Gubbi volcano in northern Ethiopia on November 23rd continues to move east. The Tokyo Volcanic Ash Advisory Center, one of nine VAACs worldwide, has now taken over responsibility for the so-called ‘ash event.

A major volcanic eruption in Ethiopia has disrupted flight operations, leading to the diversion of an IndiGo flight to Ahmedabad. Aviation authorities across India are closely monitoring the situation to ensure passenger safety amid ash plume threats. The disruption comes as ash plumes from Ethiopia’s Hayli Gubbi volcano, which erupted on Sunday for the first time in nearly 10,000 years, were projected to move towards northern India, raising concerns for flight routes passing through the region.

🌋 #HayliGubbi — a once-dormant shield volcano in Ethiopia’s Afar Rift — has exploded to life. Its ash plume soared to 45,000 ft, signaling a rare, high-energy event in a volcano with no known eruptions for millennia. Visualized: @NASAEarth 🛰 #NASA🌍 #worldview
Uno dei pochissimi video dell'intensa (e rara) eruzione esplosiva avvenuta in #Etiopia poche ore fa. Secondo il VAAC, la colonna eruttiva ha raggiunto una quota di 14 km. Tutti gli indizi portano al vulcano #HayliGubbi, che potrebbe aver prodotto la sua prima eruzione storica.

I just published an explainer on aerosols and their role in the climate that I've been working on for the past few months! It includes both how aerosols work, how emissions have changed, and how thats driven recent warming (link below).

#Spurr YELLOW/ADVISORY Information Statement Apr 17, 2025 The likelihood of a Spurr eruption has decreased from March, but the volcano remains at an elevated level of unrest & an explosive eruption (or eruptions) like those that occurred in 1953 and 1992 is still possible. (1/6)

This time 15 years ago Eyjafjallajökull in Iceland was erupting (just look at the lava bombs!). The eruption grounded over 100,000 flights and at its peak, over 20 European countries had closed their airspace. nitter.gq/cfariasvega/status/119…

After last week's announcement that the likelihood of a Mount #Spurr eruption has increased, now is a good time for Alaska residents, especially in southcentral Alaska, to familiarize themselves with the possible hazards of a Spurr eruption. (1/5)

Lo sciame sismico in corso ai #CampiFlegrei ha superato quota 350 terremoti registrati in poco più di 24 ore. Per durata e numero di eventi si tratta di uno degli sciami più importanti che si sono verificati all'interno della caldera negli ultimi 40 anni.
