Alaska's Iliamna Volcano Sees Earthquake Spike
Imagine a sleeping giant, Alaska's Iliamna volcano.
Scientists are watching it closely!
A satellite spotted the volcano and noticed more little shakes than usual.
It was rumbling, like it was clearing its throat!
These shakes, or earthquakes, happened about every minute.
But don't worry, the scientists say it's probably not waking up to erupt.
It's more likely avalanches are causing the rumbling.
The last time Iliamna really woke up was a long time ago, in 1867, but it still has little earthquakes sometimes.
A satellite image captured Alaska's Iliamna volcano.
Scientists recorded a spike in earthquakes on the volcano's slopes.
The earthquake rate initially was nearly continuous, several earthquakes per minute.
Activity is likely caused by avalanches, not an impending eruption.
Iliamna last erupted in 1867 and generates seismic activity roughly every two years.

May be the initial stages of a potential eruption.

Activity is likely not caused by volcanic unrest, but instead caused by avalanches thundering down the volcano slopes.
