FYI - doesn't sound like any cause for alarm
SISTERS, Ore. (KTVZ) -- Some two decades after first drawing widespread attention, a small (but detectable by satellite) uplift near the South Sister volcano is making news once again, with a quicker rate of rising ground than seen for years, accompanied by some small but noticeable, shallow earthquakes. But an eruption, geologists assure, is not in the cards any time soon.

just going to post you beat me to it.
Satellite radar images detected an increased rate of uplift of a 12-mile (20-km) diameter area centered about 3 miles (5 km) west of South Sister volcano. The data indicate uplift of up to 0.9 inches (2.2 cm) between June 2020 and August 2021. GPS data from a nearby continuously recording station show that the deformation has continued to the present. Additionally, seismologists observed brief bursts of small earthquakes in October 2021, December 2021, and January 2022. Most of these shallow earthquakes are too small to locate; those located are inside the uplifted area.
