Kerala’s 38,863 km² (1.18% of India’s landmass) are wedged between the Arabian Sea to the west and the Western Ghats to the east. Kerala’s coast runs some 580 km in length, while the state itself varies between 35–120 km in width. Geographically, Kerala roughly divides into three climatically distinct regions. These include the eastern highlands (rugged and cool mountainous terrain), the central midlands (rolling hills), and the western lowlands (coastal plains). Located at the extreme southern tip of the Indian subcontinent, Kerala lies near the center of the Indian tectonic plate (the Indian Plate); as such most of the state (notwithstanding isolated regions) is subject to comparatively little seismic or volcanic activity. Geologically, pre-Cambrian and Pleistocene formations comprise the bulk of Kerala’s terrain. The topography consists of a hot and wet coastal plain gradually rising in elevation to the high hills and mountains of the Western Ghats. Kerala lies between north latitudes 8°18' and 12°48' and east longitudes 74°52' and 72°22'. Kerala’s climate is mainly wet and maritime tropical, heavily influenced by the seasonal heavy rains brought by the monsoon.
