Potential quake zone. Solid red line indicates an area of about 24,000 square miles that could move during a subduction-zone earthquake, affecting 140 million people or more. The dashed line represents a scenario in which the slip might take place along a separate fault. Credit: Chris Small/Lamont-Doherty Earth Observatory

Kyoto University researchers show that details about fault dip direction can be extracted from tsunami-borne electromagnetic fields. Such details may contribute to tsunami early warning systems that are more informative for residents of coastal areas. Credit: Eiri Ono/Kyoto University (K-CONNEX)

Measurements from satellite radar images of two giant West Texas sinkholes (dark black areas) shows the ground around them is sinking, including indications a much larger potential new sinkhole is developing. The rates of east-west deformation of the ground (cm/year) are indicated in blue (eastward) and red (westward). Credit: Jin-woo Kim, SMU
