Rinjani erupted three times on 22 May 2010 with activity continuing until early on 23 May. According to the volcano's official monitoring agency, ash from Mount Barujari was reported as rising up to two km into the atmosphere and damaged crops. The volcano did not threaten villagers at that time. Lava flowed into the caldera lake, pushing its temperature up from 21 °C to 35 °C, while smoke spread 12 km.
