cerebral concussion
"Seismic" refers to an earthquake, so seismic shaking is the shaking motion of the earth (and things on it) caused by an earthquake. There are different waves that emanate from the hypocenter, or point of origin.
An earthquake is a shaking of the ground caused by shifts in the tectonic plates as they move against each other.
explosion
That's called an earthquake.
The ground shaking is caused by an earthquake in which two tectonic plates rub against each other or overlap. This happens mainly on fault lines (where two tectonic plates shift). The ancient Chinese used a system in which a ball would be in a carved Dragons mouth and depending on how big the earthquake was (how much shaking and destruction) the ball would fall into certain cups. Now we use seismographs.
The condition you are referring to is a concussion. It is a type of traumatic brain injury that occurs after a blow to the head or body that causes the brain to move rapidly back and forth. Symptoms can include headache, confusion, dizziness, and memory problems.
The violent shaking causes buildings to fall. It also causes causality loss of the people inside it.

Traumatic brain injury (TBI) is damage to the brain caused by an outside force. It is a very common brain condition. In 2010, there were about 2.5 million TBI-related deaths, hospitalizations and emergency room visits, according to the Centers for Disease Control and Prevention (CDC), and more than 50,000 people died due to TBI.
Earthquake. It is a sudden and violent shaking of the ground caused by movements within the Earth's crust, either due to volcanic activity or tectonic plate motions.

The bomb squad preliminary investigation suggests that a faulty electrical wire caused the explosion.
