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.
Casualties were reported of the said recent strong quake that jolted Cebu on the eve of September 30. President Bongbong Marcos has ordered the government agencies to provide help to the victims of the earthquake.
