Earthquakes can hardly be predicted accurately as most experts in the field agree on. Thus, most countries really make sure that they have a bureau or an organization that monitors a quake incident across their nation.
Quakes can happen in land and underwater. In the case of the latter, it can trigger tsunami thus quake-recording agencies are also often the one that monitors tsunami threats. They are the bodies releasing advisories whenever there are threats of tsunami following a strong quake shaking the land in the coastal area or underwater.
On land, quakes can result to damages and loss of lives thus it is important to be aware of the earthquake safety tips to reduce the risk of damages and loss of lives by knowing what to do.
