PVMBG reported that during 30 January-13 February diffuse white steam-and-gas plumes from vents in Tangkuban Parahu's Ratu Crater did not rise above the crater rim. At 1143 on 12 February steam-and-gas venting from Ecoma Crater (within Ratu Crater) intensified, with bursts of emissions rising 100 m above a new vent. The emissions were less intense the next day, rising 20-60 m.
Seismicity and deformation data, along with gas and temperature measurements, all indicated that the activity was the result of hydrothermal processes with no new magmatic intrusion. The Alert Level remained at 1 (on a scale of 1-4) and tourists were advised to avoid going into the crater.
