High-level eruption at Manam volcano, P.N.G.
A high-level eruption started at Manam volcano, Papua New Guinea at 16:20 UTC on April 17, 2022.
Major X1.1 solar flare erupts from Active Region 2994
A major solar flare measuring X1.1 at its peak erupted from newly numbered Active Region 2994 at 03:34 UTC on April 17, 2022. The event started at 03:17 UTC and ended at 03:51. A coronal mass ejection (CME) was produced during the event but the location of the source region does not favor Earth-directed CMEs. This will change in the days ahead as the region turns into geoeffective position.
Global temperatures at Neptune unexpectedly cooled over the past 20 years
Researchers using ground-based telescopes to track Neptune’s atmospheric temperatures over a 17-year period found a surprising drop in the planet’s global temperatures followed by dramatic warming at its south pole.
New 2022 world’s lowest temperature set on April 14 at the Vostok Station, Antarctica
A new 2022 world’s lowest temperature was set on April 14 at the Vostok Station (3 420 m / 11 220 feet) in Antarctica. The temperature dropped to -76.8 °C (-106.2 °F), a rare temperature for mid-April, said climatologist Maximiliano Herrera.
Asteroid 2022 GQ5 flew past Earth at just 0.05 LD – the second closest of the year
A newly-discovered asteroid designated 2022 GQ5 flew past Earth at a distance of just 0.05 LD / 0.00013 AU (19 447 km / 12 084 miles) at 16:20 UTC on April 8, 2022. This is the 50th known asteroid to fly past Earth within 1 lunar distance since the start of the year and the second closest of the year after 2022 FD1.

At least 137 people have been killed in floods and landslides after Tropical Cyclone “Megi” moved over the central Philippines from April 10 to 12, 2022. At least 28 others are still missing, according to official reports.
The Weekly Volcanic Activity Report: April 6 – 12, 2022
New activity/unrest was reported for 5 volcanoes from April 6 to 12, 2022. During the same period, ongoing activity was reported for 20 volcanoes.
CME hits Earth, sparking G2 – Moderate geomagnetic storm
A coronal mass ejection (CME) produced by a large filament eruption at 05:21 UTC on April 11, 2022 reached Earth around midnight UTC on April 14, sparking G2 – Moderate geomagnetic storm.
Massive earthquake swarm in Antarctica driven by magmatic intrusion at Orca volcano
New research published in Nature this month determined that an intense earthquake swarm at the Bransfield Strait, Antarctica was caused by the rapid transfer of magma from the Earth’s mantle near the crust-mantle boundary to almost the surface.
Earthquake swarm detected in the vicinity of Edgecumbe volcano, U.S.
m of earthquakes has been detected in the vicinity of Mount Edgecumbe volcano, beginning at about 10:00 UTC on April 11, 2022. The cause of the swarm is currently unknown. A small number of earthquakes were also recorded in 2020 but this swarm is unusual in the number of events. The last eruption of this volcano was in 2220 BCE (± 100 years).
