A relatively quiet week of volcanic activity has passed and as on every Thursday, the new Smithsonian / USGS Weekly Volcanic Activity Report is issued. It is summarized as follows:
-- new activity ---
Iliamna (Alaska): increased seismic and fumarolic activity
Nevado del Ruiz (Colombia): seismicity decreased but still elevated gas emissions with plumes rising 2 km

--- ongoing activity ---

Cleveland (Aleutians): small explosion on 13 March
Etna (Italy): NSEC paroxysm on 18 March
Karmysky (Kamchatka): possible ash plumes to altitude of 3.1 km (10,100 ft) a.s.l. on 14 March, thermal anomaly at summit
Kilauea (Hawai'i): lava flows about 2 km distance from coast
Kizimen (Kamchatka): moderate seismic activity, large lava flow on the E flank and accompanying hot avalanches
Popocatépetl (Mexico): steam-and-gas emissions and incandescence from the crater was visible at night. Small ash emissions occurred on 14 and 18 March, accompanied by increased incandescence from the crater.
Puyehue-Cordón Caulle (Chile): eruption from the Cordón Caulle rift zone continued at a low level, plumes rising 0.4-1.2 km above crater, drifting E and N. Incandescence observed from the crater.
Sakura-jima (Japan): strong activity during the past 10 weeks: the 12 March explosion ejected bombs landing as far as 2 km from the crater. During 14-21 March explosions often produced plumes that rose to altitudes of 1.5-2.7 km (5,000-9,000 ft) a.s.l. Ash plumes during 18-20 March that rose to altitudes of 1.2-4 km (4,000-13,000 ft) a.s.l. and drifted SE and E.
Shiveluch (Kamchatka): increasing activity since 10 March, daily explosions producing ash plumes to 3-5 km altitude (10,000-16,400 ft) a.s.l.
Soufriere Hills (Montserrat): small pyroclastic flow on 9 March
Tungurahua (Ecuador): incandescence from crater, occasional explosions
Villarica (Chile): Spattering from Villarrica's lava lake was visible during 7-9 March. 4 small ash emissions were observed during 13-14 March.
