Meteorites are hitting Mars 10 times more frequently than previously estimated, according to two new research papers that describe the seismic shock waves from these impacts detected by NASA’s now-defunct Mars InSight lander. The new rate is surprising. According to the findings, between 180 and 260 collisions occur annually on the Red Planet, and these… Read More »
In November 2022, heavy waves from Hurricane Nicole eroded the land beneath several homes in Daytona Beach, Florida.

As ocean waves rise and fall, they exert force on the seafloor below, creating seismic waves. These seismic waves are so strong and widespread that they appear as a constant sound on seismographs, the same instruments used to monitor and study earthquakes. This wave signal has become more intense in recent years, reflecting increasingly stormy… Read More »
