Morocco quake: death toll rises to 2,901. Structurally, that’s not an issue either since they tend to drop back down when the temperature warms. Yungwirth said homeowners may even experience truss uplift where the top floor ceilings literally lift off the interior walls in the winter. Houses are designed to withstand things like that.” A seismic event is any activity that causes vibrations within the earth, particularly its crust. “What you’re getting is maybe a fastener or nail letting go a little bit or the wood moving against another piece of wood and that’s what you hear. Frost quakes (or 'cryoseisms,' if you want to get technical), are seismic events that typically occur in Earth’s boreal or cold, temperate regions. Frost quakes are seismic events that are weather-related. “It’s the structural components of your house moving slightly because of the temperature differential between the inside and outside,” Yungwirth said. For this reason, sites of frost quake activity are rarely instrumented. Furthermore, frost quakes seem to occur at random, or less predictable, locations (UTSC Climate Lab, 2020).

While booms and cracks in and around your house can be alarming, they’re not a cause for concern according to local contractor Dan Yungwirth with Miller Contracting.
