Analysing the 1811-1812 New Madrid earthquakes with recent instrumentally recorded aftershocks

Article Abstract:

The study uses instrumentally recorded aftershock locations and models of elastic stress change to develop a kinematically consistent reputure scenario for three of the four largest earthquakes of the 1811-1812 New Madrid sequence. The results of this study propose that the future large midplate earthquakes sequences may extend over a much broader region than previously suspected.

Great Himalayan earthquakes and the Tibetan plateau

Article Abstract:

The relationship between the Himalayan earthquakes and the Tibetan plateau is discussed. It is shown that the Tibetan reservoir of elastic strain energy is drained in proportion to Himalayan rupture length and that the consequent growth of slip and magnitude with rupture area can be used to infer a ~500-year renewal time for the earthquakes.

Aftershocks driven by a high-pressure CO2 source at depth

Article Abstract:

In 1997, an earthquake of magnitudes 5.7 and 6 hit Northern Italy along with thousands of aftershocks. This sequence of earthquake is said to have driven by a fluid pressure pulse generated from the coseismic release of a known deep source of trapped high-pressure carbon dioxide.
