The effusive eruption of the volcano continues.
The daily volcanic tremor shows fluctuating values over the past 24 hours.
Small lava fountains, about 15 m tall, continue to reach the cone height and intermittently overshoot its height.
A part of the fluid lava is going directly into lava tubes formed at the foot of the cone reaching several hundred meters in length.
Lava flows have advanced in less than 100 meters since the last update.
Scientists were allowed to take new samples of the lava flow yesterday afternoon.
The ground deformation measurements detected a slight deflation under the summit area reflecting magma intrusion and migration within the volcano edifice.
