Though it's impossible to accurately predict most natural disasters, scientists use different
tools to monitor the chances of their happening. Landslides are an issue in many parts of
the world. Researchers in Italy are trying to improve landslide monitoring using optical
fiber sensors. The sensors are embedded in mountain slopes to keep track of movement.
Volcanoes such as Mount Etna in Italy and Mount St. Helens in the United States are a
constant threat. Both have been active in recent years. To help people prepare for an
eruption, experts can monitor active volcanoes with satellite cameras. These cameras are
used to detect increasing temperatures around volcanoes. Earthquakes are also a concern
in many areas. To aid earthquake-monitoring efforts, researchers use laser beams, which
can detect plate movements in the earth's crust.
