Despite the advancement in technologies, including satel- lite imagery, it is still a challenge to measure the impact of a typhoon, especially during a landfall. Up until today, the impact of a typhoon is still devastating not only to human lives but also to properties as well as the environment. To make it worse, this weather system can create a damag- ing horizontal wind with speeds up to 300 km per hour, accompanied by torrential rains, tornadoes, and a vicious phenomenon known as storm surge. A storm surge is an elevation of the sea surface that can reach up to 6 meters (20 feet) above the normal levels, and its impact is similar to that of a tsunami.
