: The Alaska Volcano Observatory detected that a new (so far minor) eruptive episode has started at the volcano recently:

Thus the volcano has entered a renewed period of unrest and we are raising the Color Code to Yellow and the Alert Level to Advisory.
The increase in temperature at the summit is consistent with renewed growth of the small lava dome within the summit crater. The possibility of sudden explosions has increased." (AVO)

We truly love working to bring you the latest volcano and earthquake data from around the world. Maintaining our website and our free apps does require, however, considerable time and resources.
Our server is reaching its limits and we need financing to increase capacity in order to deal with huge activity peaks when quakes occur. We're aiming to achieve uninterrupted service wherever an earthquake or volcano eruption unfolds, and your donations can make it happen! Every penny counts and every donation will be highly appreciated.
