Poás volcano (Costa Rica): continuing eruptions, crater lake has disappeared

As a result of the recent eruptions, the crater lake has disappeared. At the place of the old lava dome near the center of the crater, a small pyroclastic cone has formed around the main emission point.
Strong sulfur gas (SO2) emission is also occurring from other vents at the crater floor, indicating the presence of magma at shallow depth.
During the month of June and this first half of July, the activity consisted of intermittent, passive ash eruptions of varying duration, with sometimes smaller quantities of solid materials including incandescent rock fragments ejected.
Between 8-12 July, several volcano-tectonic earthquakes of magnitudes up to 4, indicators of internal rock fracturing (due to fluid pressure) were recorded at shallow depths of less than 1 km under the crater floor. RSN also reported moderate volcanic tremor and other seismic signals associated with fluid circulation processes.
