Repeating earthquakes, or repeaters, are defined as earthquakes with overlapping rupture areas, sharing a similar location, magnitude and focal mechanism1,2,3. Due to the similarity of their sources, they generally produce highly similar waveforms1,2,3,4,5,6,7. Indeed, while a robust identifica...
in the case of trapdoor or ring-faulting in response to pressurisation or depressurization of magmatic reservoirs and conduits. In many cases, however, we observe so-called quasi anti-repeaters, which have a reversed focal mechanism but occur on neighbouring structures. These earthquakes can be mo...
Stromatolites are very rare today but were numerous in earlier stages of life on Earth. They are layered structures which are found in shallow water when sedimentary grains are bond, trapped or cemented. Answer and Explanation:1 Fossilized stromatolites are known as the Earth's earliest fossil e...
In addition to the volcanic eruptions and earthquakes associated with convergent and divergent plate boundaries, why are these boundaries associated with the formation and accumulation of various metallic ore deposits? Describe the basic differences between continental crust and ocea...
Understanding the mechanics of such volcanic earthquakes is important to elucidate eruptive processes and to assess related hazards. This, however, is a challenging goal because of the co-involvement of multiphase (gas/liquid/solid) thermal effects, large changes in physical properties (strength, visco...
