Cleveland (Aleutians): small explosions on 7 and 9 March
Ijen (East Java, Indonesia): raised alert because of increased seismicity and visual observations
Iliamna (Alaska): increasing seismic activity, alert raised to yellow
Lamongan (East Java, Indonesia): raised alert because of increased seismic activity and steaming
Marapi (Sumatra, Indonesia): ash eruptions in early March
Nevado del Ruiz (Colombia): significant increase in seismicity during 5-11 March, large gas plume
