The most widely recognized types of disasters are those listed here. Disasters related to extreme weather events (floods, cyclones, tornadoes, blizzards, droughts) occur regularly. Events related to extremes of the the earth's geology (earthquakes, volcanic eruptions) occur less frequently and are rare events in New England, but result in major consequences when they happen.
Disasters may occur suddenly in time (a quick onset), or they may develop over a period of time (a slow onset). Most occur suddenly and perhaps unexpectedly. However, some events develop gradually, including some floods and famines related to drought.
The most common types of disaster experienced in Providence are related to flooding from spring and summer thunderstorms as well as the threat of Atlantic Hurricanes.
