BREAKING: California’s “Sleeping” Lassen Volcano Awakens — Experts Ask “How Did This Happen?”

Описание: Scientists across California are sounding urgent alarms — and this warning is no longer hypothetical. Deep beneath the Eastern Sierra, seismological instruments and satellite data are showing renewed unrest in one of the state’s most closely watched volcanic regions: the Long Valley Caldera, where thousands of small earthquakes in recent years have forced scientists to re-check assumptions about what “quiet” really means.

But the internet is already spinning this into something it’s not.

False rumors about “supervolcano doomsday” and volcano-to-volcano chain reactions are flooding social media — and USGS experts stress that most of those claims are exaggerated or misleading. Still, the underlying activity is real enough to matter. Scientists at institutions like the USGS and Caltech are monitoring earthquake swarms, subtle ground deformation, and gas emissions because these are the exact signals that can indicate shifting fluids and changing pressure deep underground.

The unsettling truth is this: California doesn’t need an apocalypse to face a crisis. A moderate volcanic event — ash, gas, lahars, road closures, power disruptions — could still be regionally devastating. And with multiple high-risk volcanic systems in the state, preparedness is no longer optional for communities near these zones.

In this video, we break down:
• What the Long Valley Caldera is — and why it’s still geologically active
• Why earthquake swarms beneath volcanoes matter (and what they usually mean)
• What satellite data can reveal about uplift and “inflation” from magma or fluids
• Why “supervolcano” claims about California are often wrong — but the risk isn’t zero
• The three California volcanoes ranked among the highest-risk in the U.S.
• Why volcanic gas (like CO₂) can be a silent hazard even without an eruption
• Whether earthquakes can “trigger” eruptions — and what science actually says
• What a realistic eruption scenario would impact: air quality, highways, water, power, tourism

This isn’t a story about fear — it’s a story about signal versus noise. California’s volcanoes are not movie plots, but they are living systems. And the real danger grows when misinformation spreads faster than science, leaving communities either panicked — or unprepared.
