Storm surges are generated by intense low-pressure systems, such as hurricanes or cyclones, which push water towards the shore. The strong winds associated with these storms create large waves that can raise sea levels significantly, leading to the inundation of coastal areas. Storm surges can cause widespread flooding and damage to infrastructure, making them a significant hazard during severe weather events.

A tsunami moves with great force, generated by disturbances like earthquakes or landslides underwater, causing surges of water that can travel across oceans at high speeds.
Lightning can cause damage to buildings by starting fires, creating power surges that can damage electrical systems, and causing structural damage due to the intense heat and pressure generated. Buildings with lightning protection systems can help mitigate these risks by safely directing the electrical charge into the ground.
Black holes form when massive stars collapse under their own gravity. The intense gravitational pull of a black hole traps everything, including light. Black holes are hot because of the high temperatures and energy generated by the matter falling into them, which creates intense radiation and heat.
The term for the period where no impulse can be generated despite intense stimulation is known as the absolute refractory period. During this time, the cell membrane is unable to propagate another action potential, ensuring that signals are unidirectional and preventing the possibility of signal backflow.
Electromagnetic pulses generated by a nuclear blast can induce high voltage surges in electrical circuits, damaging components and causing malfunctions or shutdowns in electronic devices. This phenomenon, known as an EMP, can overload and disrupt the sensitive electronics in these devices, leading to their shutdown.
