India – Torrential rain in the wake of cyclone Mora led to flooding at many places along river banks in Manipur’s hills and valleys on Wednesday. Although there were no human casualties, many localities in Imphal East, Imphal West, Thoubal, Kakching, Senapati districts faced flash flood after many rivers including Imphal, Sekmai, Wangjing and Senapati breached their banks at various locations in the morning. Rain and flash floods also destroyed standing crops in Kakching,Thoubal and Ukhrul districts.

Roundup of Global Volcanic Activity – New Activity for the week of 24 May – 30 May 2017

Poas | Costa Rica : OVSICORI-UNA reported that tremor amplitude at Poás fluctuated between low and high levels during 23-30 May, often corresponding to the vigor of emissions of water vapor, magmatic gases, and material from fumarolic vents. During 25-26 May ashfall was reported in some communities around the volcano. Low magnitude volcano-tectonic earthquakes and small phreatic eruptions were recorded sporadically during 27-30 May.

Rincon de la Vieja | Costa Rica : OVSICORI-UNA reported that a small hydrothermal explosion occurred at 1020 on 23 May in Rincón de la Vieja’s crater lake, producing a small lahar that traveled down the N flank of the crater.

Sheveluch | Central Kamchatka (Russia) : KVERT reported that during 23-25 May powerful explosions at Sheveluch generated ash plumes that rose 8 km (26,200 ft) a.s.l. and drifted 715 km in different directions. At 0830 on 25 May explosions generated ash plumes that rose 9-10 km (29,500-32,800 ft) a.s.l. and drifted 16 km NE. The Aviation colour Code (ACC) was raised to Red (the highest colour on a four-colour scale). Around 30 minutes later the ash plume was identified in satellite images drifting 45 km ENE. Strong steam-and-gas emissions rose from the lava dome. The ACC was lowered to Orange. Within the next hour the ash plume drifted 82 km E.
