A newly-discovered asteroid designated 2021 SP flew past Earth at a distance of 0.03 LD or 0.0000943 AU (14 107 km / 8 765 miles) from the center of our planet or about 7 700 km (4 780 miles) from the surface on September 17, 2021. This is now the closest asteroid…
Lava flows continue slowly advancing toward the coast on September 23, 2021, after another night of intense lava fountains at Cumbre Vieja volcano, La Palma, Canary Islands. The height of the volcanic plume is estimated at 4.2 km (13 800 feet) above the volcano….
A strong increase in the amplitude of volcanic tremor was observed at Cumbre Vieja volcano, La Palma, Canary Islands around 12:00 UTC on September 21, indicating the intensity of strombolian activity is increasing. The activity further intensified on September 22…
Cumbre Vieja volcano on La Palma island, Canary Islands finally erupted on September 19, 2021, after 8 days of intense seismicity. This is the first eruption at the volcano since 1971. Seismicity further increased during the UTC morning on September 19, leading to…
Ash emissions from the ongoing eruption at Semisopochnoi volcano, Alaska have increased in frequency and intensity, prompting the Alaska Volcano Observatory (AVO) to raise the Aviation Color Code to Red at 05:58 UTC on September 20, 2021. Satellite images show an…
According to Benedikt Gunnar Ófeigsson, deformation scientist at the Icelandic Met Office (IMO), there is every indication that the Grímsvötn volcano is ready to erupt. The last eruption of this volcano took place in 2011 — it was a large and…
Seismic activity under Cumbre Vieja, La Palma, Canary Islands continues to migrate slightly to the northwest, at depths of around 8 km (5 miles), with 20 shallow earthquakes at depths between 1 and 3 km (0.6 – 1.8 miles). The maximum accumulated deformation reached…
A bright fireball — most likely a small asteroid or a comet — struck Jupiter at 22:39 UTC on September 13, 2021. The impact was seen and captured by astronomers across the world who were observing the ongoing transit of the shadow of Jupiter's moon Io. "A…
A strong swarm of shallow earthquakes started under Cumbre Vieja volcano1, La Palma island, the Canary Islands on September 11, 2021, leading authorities to raise the Alert Level from Green to Yellow on September 13. There have been 10 swarms in this area of the…
A newly-discovered asteroid designated 2021 RG6 will fly past Earth at a distance of 0.22 LD / 0.00057 AU (85 270 km / 52 980 miles) from the center of our planet at 15:31 UTC on September 11, 2021. Since the start of the year, our sky surveys have identified a…
