Indonesia experiences massive forest fires as the dry season approaches. They are a major environmental challenge because they damage forests and other land, endanger lives, and disrupt local economies. Using sharp, high-resolution ...
If there is a magnitude 8 or 9 megathrust earthquake off the coast of the Pacific Northwest, data from ocean bottom seismometers (OBS) could improve earthquake detection times calculated by the ShakeAlert system.
