rains. The river has overflowed, spilling its waters on the low-lying towns of Liloan and San Vicente and destroyed an ongoing flood control project worth millions of pesos. The river meanders along its course, ever changing its way over time. During the time it floods, it destroys every side of its course. In 2001, portions of the road and banks in Barangay San Miguel along the river were destroyed, including part of the Philippine National Road. Local officials blamed the rechannelization and uncontrolled quarrying of gravel and sand at the side of the river as the cause of the flood. At a meeting on March 18, 2002, one of the representatives of a government agency alleged that the reason of the incidents of flood and other environmental problems in the river was due to the "Philippine Fault" which caused rocks to rumble down. However, the reason was contended because the fault is a geological feature and environmental problems in the province just occurred that time. Along with other mountain forms in the province, Mount Nacolod in Hinunangan town has the highest peak with an elevation of above sea level. Young volcanic rocks are discovered in the terrain areas, which cover the top of the southern mountain ranges of Mount Cabalian in the Pacific Area and Mount Nelangcapan in Panaon Area. The province lies within the Philippine Fault System. The major fault lines traverse the municipalities of Sogod, Libagon, Saint Bernard and San Juan to Panaon Island. Based on Mines and Geosciences Bureau Region 8 data, these areas had experienced strong earthquakes in 1907 and 1948 with a magnitude of 6.9 and on July 5, 1984, with a 6.4 scale. The Mines and Geosciences Bureau warned that Southern Leyte's natural and geological features make it susceptible to landslides and floodings. The affiliated group stated that there are four contributory reasons: unusually heavy rains; numerous faults and badly broken rocks; steep slopes; and absence of effective vegetative cover. The province has numerous types of soil. Soil types within the Maasin Clay, Guimbalaon Clay, Himay-angan Clay, Bolinao Clay, Quingua Clay and Malitbog Clay series serve as raw materials for ceramics and pottery made by local residents. Climate Southern Leyte has two types of climate according to the Coronas Classification. These are Type II and Type IV. Type II is characterized by the absence of dry season with a very pronounced maximum rain period
