The recursive occurrence of geohazards (among which volcanic eruptions,
earthquakes, tsunamis, bolides) on our Planet throughout the last few millennia has
often impacted human settlements on local and regional scales, causing significant
deaths and losses of goods and structures. In some extreme cases such events have so
dramatically impacted the environment on global scale to inflict catastrophic losses to
populations.
The current status of our Planet, characterized by societies progressively
clustering around megacities, often located in hazardous areas and heavily depending
from fast and efficient transfer of information and persons faces the crucial challenge of
developing an effective resilience program to geohazards and, in particular, to extreme
geohazards.
Most of the decision-making and emergency centres are located in large
settlements or megacities, making it thus crucial to assure a constant and efficient level
of sustainability of such structures in order to enable timely decisions and support
actions at local, regional and global level even under the worse environmental
conditions.
The development of an effective Disaster Risk Reduction program and of a
consequent robust resilience program needs to be based on a holistic approach,
addressing scientific, technical, logistic, social and policy aspects related to hazards and
involving all the principal stakeholders facing this challenge: scientific experts of
geohazards, social sciences experts, government officials and policy makers.
The main tool supporting such holistic approach should be a Global Network of
Monitoring Systems, based on synergetic technologies capable of acquiring and sharing
in real-time (or near-real time) high quality data recorded on a global scale: the
systematic and comprehensive analysis of such data would allow the development of a
deeper understanding of the phaenomena associated to geohazards and would enable the
principal stakeholders involved in Disaster Risk Reduction and Resilience to issue early
warnings to populations.
Some examples of events and of the contribution to their monitoring through
existing global networks will be provided.
