Extraños estruendos tras tormenta invernal: qué son los “temblores de hielo” que alarmaron a EEUU
Las temperaturas extremadamente bajas pueden generar distintos peligros, como hipotermia o la caída de árboles por el hielo; sin embargo, hay un fenómeno aún […]

TL;DR
- Unusual booms and vibrations were reported in parts of the US following a historic winter storm.
- The phenomenon is explained as 'frost quakes' or 'cryoseisms'.
- Frost quakes happen when frozen ground cracks suddenly during rapid temperature drops.
- The expansion of freezing water in the soil causes pressure that leads to the ground breaking.
- These events often occur at night after a slight temperature increase.
- A deep layer of snow can prevent frost quakes by acting as insulation.
- Frost quakes are not related to tectonic plate movement and are generally not dangerous.
- Potential effects include shaking windows, vibrating walls, and cracking surfaces like driveways.
