A 4.8 magnitude earthquake shook New Jersey and New York City residents, causing shaking of furniture and floors with no major disruptions reported. Experts explained that earthquakes are common in the region, typically at lower magnitudes. Aftershocks, which are small earthquakes following the mainshock, could occur. Bath’s law states aftershocks are usually 1.2 magnitude units smaller than the mainshock, while Omori’s law predicts a decrease in aftershocks over time.
Aftershocks refer to readjustments near faults and can be damaging or deadly. They are different from swarms, which are small earthquakes associated with geothermal activity. Globally, there is a 6% chance of an aftershock leading to a larger earthquake within 3 days, and in California, about half of major earthquakes were preceded by foreshocks.
Earthquakes occur due to the slip on a fault between two rock blocks. Seismic waves generated by the movement of tectonic plates cause the ground to shake. During an earthquake, individuals are advised to stay indoors away from potential hazards, stay in open areas when outside, and avoid driving unless necessary.
After an earthquake, it’s important to listen to radio for instructions, check for fire hazards, avoid driving to keep roads clear for emergency vehicles, and check for potential structural damage. The article also provides tips for staying safe during and after an earthquake and emphasizes the importance of staying informed and prepared for such natural disasters.
