and a dislocated village; and Ain Baal to the South-East, also without agricultural lands and dislocated villages. Tyre's urban area lies on a fertile coastal plain, which explains the fact that as of 2017 about 44% of its territory was used for intra-urban agriculture, while built-up land constituted over 40%. In terms of geomorphology and seismicity, Tyre is close to the Roum Fault and the Yammouneh Fault. Though it has suffered a number of devastating earthquakes over the millennia, the threat level is considered to be low in most places and moderate in a few others. However, a tsunami following an earthquake and subsequent landslides and floods pose major natural risks to the Tyrian population. Vast reserves of natural gas are estimated to lie beneath Lebanese waters, much of it off Tyre's coast, but exploitation has been delayed by border disputes with Israel. Etymology Early names of Tyre include Akkadian Ṣurru, Phoenician Ṣūr (), and Hebrew Ṣōr (). In Semitic languages, the name of the city means "rock" after the rocky formation on which the town was originally built. The predominant form in Classical Greek was Týros (Τύρος), which was first seen in the works of Herodotus but may have been adopted considerably earlier. It gave rise to Latin Tyrus, which entered English during the Middle English period as Tyre. The demonym for Tyre is Tyrian, and the inhabitants are Tyrians. Climate Tyre has a Hot-summer mediterranean climate (classified as Csa under the Köppen climate classification), characterized by six months of drought from May to October. On average, it has 300 days of sun a year and a yearly temperature of 20.8°C. The average maximum temperature reaches its highest at 30.8 °C in August and the average minimum temperature its lowest at 10 °C in January. On average, the mean annual precipitation reaches up to 645 mm. The temperature of the sea water reaches a minimum of 17 °C in February and a maximum of 32 °C in August. At a depth of 70 m it is constantly at 17–18 °C. Meanwhile, rising sea levels due to global warming threaten coastal erosion to Tyre's peninsula and bay areas. History Roman historian Justin wrote that the original founders arrived from the nearby city of Sidon in the quest to establish a new harbor. Doric Greek historian Herodotus (c. 484–425 BC), born in the city of Halicarnassus under the Achaemenid Empire, visited
