A strong and deep earthquake registered as M6.5 by USGS hit near Ndoi Island, Fiji at 21:28 UTC on June 21, 2015. USGS is reporting depth of 563.5 km (350.1 miles.). EMSC is reporting the same magnitude at a depth of 553 km (343 miles).According to the USGS, epicenter w
Active Region 2371, now classifiead as Beta-Gamma-Delta and located near the center of the disk, erupted with two M-class solar flares – M2.0 and M2.7 – early on June 21, 2015 producing Earth-directed full-halo Coronal Mass Ejection (CME). Arrival is expected midday Jun
Filament eruption in the SSE quadrant of the Sun produced a partial-halo Coronal Mass Ejection (CME) first observed in coronagraph imagery near 08:45 UTC on June 19 (above). WSA-Enlil model suggests a glancing blow early on June 23. Beta-Gamma-Delta classified…
NOAA Fisheries’ Northwest Fisheries Science Center in Seattle has mobilized extra scientists to join a fisheries survey along the West Coast to chart an extensive harmful algal bloom (HAB) that spans much of the West Coast and has triggered numerous closures of im
A strong and shallow earthquake registered by USGS as M6.4 hit near the coast of Conception, Chile at 02:10 UTC on June 20, 2015. USGS is reporting depth of 10 km (6.2 miles). EMSC is reporting Mw6.6 at a depth of 2 km (1.2 miles). CSN Chile registered it as Mw6.4 at a
Large pyroclastic flows have again been observed at Mount Sinabung, Indonesia early June 19, 2015. There are no confirmed historical eruptions of this volcano recorded prior to explosive eruptions during August – September 2010 that produced ash plumes to 5 km above
Beta-Gamma classified Region 2371 produced a long duration M3.0 solar flare peaking at 17:35 UTC on June 18, 2015. The event started at 16:25 and ended at 19:00 UTC. A full-halo Coronal Mass Ejection (CME) was produced, it will likely make a glancing blow at Earth late
New activity/unrest was observed at 6 volcanoes from June 10 – 16, 2015. During the same period, ongoing activity was observed at 13 volcanoes. New activity/unrest: Asamayama, Honshu (Japan) | Barren Island, Andaman Islands (India) | Concepcion, Nicaragua | Cotopaxi, Ec
A long duration M1.2 solar flare erupted from the vicinity of departing Region 2365, off the southwest limb, at 01:27 UTC on June 18, 2015. The event produced a large Coronal Mass Ejection (CME) and is currently causing solar radiation storm on Earth, reaching S1 (Minor
A very strong and shallow earthquake M7.0 was registered at southern Mid-Atlantic Ridge at 12:51 UTC on June 17, 2015. USGS reports depth of 10 km (6.2 miles). EMSC reports Mw6.9 at a depth of 10 km.According to the USGS, epicenter was located 495 km (308 miles) WNW of
