Slow slip plays a major role in accommodating the relative motion at the boundaries between tectonic plates. Lasting from seconds to months, no single geophysical instrument is able to observe the full continuum of slow slip. Here, we jointly analyze seismic and geodetic data from the Mexican subduction zone to explore this instrumental blind spot, and report on the first observations of hours-long slow transients that occur daily. We find that these slow transients scale like ordinary earthquakes, suggesting that slow and fast slip are different constituents of a broad spectrum of transient slip.
