A drying lake is triggering weird seismic activity deep beneath its basin
We tend to think earthquakes are predominantly driven by deep-Earth forces. But in Kenya’s Lake Turkana Rift, researchers recently found that as surface water levels dropped roughly 100 to 150 meters (328 to 492 ft), fault activity accelerated and increased magma flux. The discovery reshapes long-held assumptions about what drives tectonic change. If lake-level fluctuations can stir the shallow crust, then our climate’s past and future may matte…
Puracé Volcano in Southwest Colombia Shows Increased Seismic Activity
The Puracé volcano in southwest Colombia has registered a noticeable uptick in seismic and gas-emission activity over the last 24-hours, prompting authorities to maintain heightened monitoring of one of the country’s most active volcanic systems. The Colombian Geological Service, known as the SGC, said the latest measurements indicate an increase in seismic signals associated with the movement of fluids beneath the crater. Those signals — includ…
Alert for increased seismic activity and emissions of gases in the volcano Puracé Agencia Period... Mar, 25/11/2025 - 12:48 The SGC reported signals associated with fluid movement under the crater and columns up to 1.6 kilometers; the alert level is maintained in yellow, with possibility of ash emissions and minor events.
