Hydro-met hazards, such as floods, storms, cyclones and drought, appear to have become more common over time, perhaps because of global warming and human environmental management issues such as deforestation.
Tectonic disasters, i.e. the events, have not increased or decreased over time. The number of events is broadly the same decade over decade.
Trends for disasters (past vs present):
Deaths have fallen
number of reported disasters have increased
number of people affected has risen due to population growth
