The effusive-explosive eruption of the Pacaya volcano in Guatemala has been increasing during the past days confirmed by the INSIVUMEH volcano observatory.A new effusive eruption has been producing two lava flows that started to descend slowly from vents on the northern flanks, currently about 50 m and 200 m long. New vents are eruptive fissures.
Friday, 8 January 2021 The 4th and 5th major quakes of 2021 rocked the Kermadec Islands and Vanuatu in the South Pacific: All five major quakes this year have happened around the Pacific Ring Of Fire as well as more than 20 volcanoes erupting or showing activity there too
The lava flow on the southwestern slope remains active, currently about 550 m long. A moderate-to-strong eruptive episode of strombolian explosions is now in progress at the volcano's Mackenney summit crater characterized by higher-than-usual dense ash plumes that rose to estimated 3 km altitude as can be seen in the video recorded below. Blocks were ejected as far as 300 m away from the crater.
