Crust and upper-mantle seismic anisotropy variations from the coast to inland in central and Southern Mexico (2): Correlations with Tectonic Tremor

Seismic anisotropy in the flat slab region of Mexico is compared with tectonic tremor activity. The anisotropy is observed in three separate horizontal layers using a novel technique with receiver functions. Those layers are identified as the …

Isolated Triggered Tremor Spots in South America: Southern Chile, Ecuador, and Central Colombia

We report new observations of triggered tectonic tremor in three regions in South America along the plate boundary between the Nazca and South America plates: southern Chile, Ecuador, and central Colombia. In these regions, tremor was observed during …

Characteristic tectonic tremor activity observed over multiple slow slip cycles in the Mexican subduction zone

We develop a single-station tremor spectrum template detection method that we applied to continuous seismic data recorded by the Mexican National Seismological Service broadband stations. This allows for an unprecedented long-term analysis of …

Slow slip hidden in the noise: the intermittence of tectonic release

Referred to as slow slip events, the transient aseismic slip that occurs along plate boundaries can be indirectly characterized through colocated seismicity, such as tectonic tremor and low-frequency earthquakes (LFEs). Using the timing of cataloged …
