Supercomputers and artificial intelligence (AI) are transforming the field of disaster prediction by enabling the analysis of vast datasets and simulating complex scenarios with unprecedented precision. These technologies are crucial for forecasting disasters, preparing mitigation strategies, and reducing vulnerability to natural hazards. This module explores the role of supercomputers and AI in disaster prediction, their applications, challenges, and future potential.

What Are Supercomputers?

Supercomputers are high-performance computing systems designed to process and analyse massive amounts of data at incredible speeds. Unlike general-purpose computers, supercomputers perform trillions of calculations per second, making them indispensable for solving complex scientific and engineering problems.

Figure 31. Summit (USA), revealed in 2018 with peak performance of 200,000 trillion calculations per second, or 200 petraflops. Summit is mainly used for energy, advanced materials and artificial intelligence (AI), among other sectors, “enabling scientific discoveries that were previously impractical or impossible” - OLCF at ORNL, 2018.

Note

Supercomputers are effectively many central processing units (CPU’s) acting one programme in parallel with each other. For example, for flood prediction, supercomputers can use vast amounts of datasets, such as precipitation, soil permeability, soil moisture capacity, etc., to create many simulations on potential river runoff volume, and then make predictions on flood intensity and duration.
