Natural hazards and related issues of Meghalaya
As the State lies in the seismically active zone, special emphasis should be given to reduce the impacts of earthquake. Moreover, it is also affected by hazards such as floods, flash floods, epidemics, fire, hailstorm, lightening, road accidents, etc.
Earthquake
The State of Meghalaya has witnessed seismic events of ‘8.7 magnitude in 1897’. This region has been identified as a potential site of a future catastrophic earthquake. With the growth of population and infrastructure seismic vulnerability has increased and previous earthquakes have provided a glimpse of the devastating potential of seismic tremors.
Cyclones
Meghalaya is situated in the north eastern direction of Bangladesh which is highly prone to cyclone/ winds. Every year about 60% of the area is affected by cyclone in Bangladesh. The Districts of West Jaintia Hills and East Jaintia Hills may experience a wind speed of up to 55m/s. Occasional cyclones do occur in western Meghalaya their severity being more during monsoon season. The Districts close to Bangladesh like South West Garo Hills, South Garo Hills, South West Khasi Hills, West Khasi Hills, fall in very high cyclonic zone due to close proximity to Bay of Bengal (which is a cyclone basin). In this zone wind speed can reach up-to 50 m/s, which can cause large scale damages. The Bay of Bengal accounts for seven percent of the annual tropical cyclone activity worldwide; the recorded frequency of cyclones per year along the Bay of Bengal is four and inevitably one of the four transforms into a severe cyclone causing human and property losses
Floods
The State with hilly terrain does not suffer from a major problem from floods, However, due to heavy rain, flash floods may be caused resulting in river bank erosion and some local damage. In Meghalaya, 
floods occur in river valleys, when flow exceeds the capacity of the river channel, particularly at bends or meanders. The plain areas of Meghalaya adjoining Assam are affected by flood due to the back flow of water from the River Brahmaputra during the flood season between June and October. The tributaries like Krishnai, Jinari, Jingjiram, Rongai, Dudhnoi, Ringgi, Gohai, Dilni etc cause flood in the plain areas of the State.
Landsides
Meghalaya being a hilly terrain is prone to landslides. Every year a number of landslides have been reported from various localities. These cause a lot of miseries to public, resulting in loss of lives and properties, disruption of communication network, besides causing economic burden on the society. Landslide is primarily attributed to high slope, immature geology, neo-tectonic activity, heavy rainfall, unplanned and improper land use practice in the State. Landslides generally occur during heavy rains, that is during the months of June to October in Meghalaya.
Southern part of Meghalaya is more susceptible to Landslides than the Northern Part. National Highways like Bajengdoba-Tura-Dalu, Damra–Siju-Baghmara, Guwahati – Shillong- Tamabil, and Shillong- Jowai- Badarpur are prone to landslides.
Landslide occurred frequently at Sonapur on Shillong- Jowai- Badarpur Road, but now the problem has been mitigated by constructing a tunnel for the vehicular traffic. Urban areas of Shillong and Tura, Jowai are also prone to landslides due to the faulty Construction of Houses and rapid Urbanization.
Lightning and Hailstorms
Lightning occurs during the monsoon months and can strike at any place. Hailstorm generally occurs in the pre and post monsoon months. Some loss of crops lives and properties due to lightning and hailstorms are reported in the state.
