Northern Ash and Gas Eruptions north of latitude 23°N.
KARYMSKY Kamchatka Peninsula, Russia 54.05°N, 159.43°E; summit elev. 1,536 m (3 km)
seismicity above background levels during 11-18 March, on 12 March possible ash plumes extending ~10 km (6.2 mi) E of the volcano, small ash clouds extending ~7 km (4.4 mi) N, and ash deposits on the southern sector of Karymsky; on 14 March possible ash-and-gas explosions reached heights of ~3 km
KLIUCHEVSKOI Kamchatka Peninsula, Russia 56.06°N, 160.64°E; summit elev. 4,835 m (8.5 km)
eruptive activity continuing during 11-18 March with Strombolian explosions intermittently from a cinder cone in the summit crater with lava flows extending from this cinder cone down the NW flank, occasional vigorous explosions from the summit crater and along the path of the lava flow producing ash plumes that reached as high as 7-8 km and drifting many tens or hundreds of kilometers downwind, ash-and-gas plumes rising to 8.0 km on 11-12 March, Strombolian bursts rose 5.3-5.8 km, on 15 March two lava flows observed on the NW slope; as of 24 March eruptive activity increased, continuous explosions from the summit crater potentially producing ash plumes as high as 10 km; current activity very dangerous to aviation, according to visual and video data a gas-steam plume containing some amounts of ash to ~7.5 km on March 22 and up to ~ 8.5 km on March 23, an ash plume rising to 7.0 km and extending 70-80 km to the north-west observed by pilots at 23:05 UTC on March 23

during 16-21 March several ash explosions, ash plumes to a maximum height of 5.1 km, lava avalanches down the SW flank of Caliente Dome
SOUFRIÈRE HILLS Montserrat, West Indies 16.72°N, 62.18°W; summit elev. 1,052 m (0)
seismic activity at low levels during 11-18 March, the sulfur-dioxide flux ranging between 235 and 630 metric tons per day, with an average of 425 metric tons per day, below the long-term average for the eruption of 500 metric tons per day
TUNGURAHUA Ecuador 1.47°S, 78.44°W; summit elev. 5,023 m (low)
during 16-21 March volcanic activity at relatively low levels, low-energy gas-and-steam plumes emitted

SPECIAL NOTE
A Really Destructive Chinese Earthquake
Thanks to Rimidu on Pinpoint-Newsletter (Google).
This paper is an easily read yet intense study of the Tangshan earthquake in 1976, the worst in 400 years in China.
