Research Guide

What is Slow Slip Events?

Slow slip events (SSEs) are aseismic slip phenomena occurring along plate boundary faults at rates slower than regular earthquakes but faster than tectonic creep, detected primarily through geodetic measurements.

SSEs last from days to years and release stress without generating seismic waves (Scholz, 1990). They occur at subduction zones and continental faults, often accompanying tremors or foreshocks. Over 500 papers document SSEs since their discovery in the 2000s, building on fault mechanics foundations.

Key Challenges

Why It Matters

SSEs reveal fault frictional properties, distinguishing stable sliding from stick-slip behavior critical for megathrust earthquake cycles (Scholz, 1990). Geodetic monitoring of SSEs improves probabilistic forecasts by identifying stress shadows and triggering zones (DeMets et al., 2010). In regions like Cascadia and Japan, SSE patterns guide tsunami hazard maps and evacuation planning (Zhang et al., 2004). Plate motion models refine SSE recurrence predictions (Minster and Jordan, 1978).

Key Research Challenges

Detecting weak SSE signals

Geodetic networks struggle to isolate SSE displacement from noise and postseismic relaxation. GPS time series require advanced filtering (Altamimi et al., 2016). Citation graphs show sparse data in many subduction zones.

Modeling SSE triggering

Rate-and-state friction laws fail to fully explain SSE initiation and migration without ad-hoc parameters (Scholz, 1990). Linking SSEs to distant earthquakes needs improved dynamic Coulomb stress models. Tibetan Plateau GPS data highlights internal deformation complexities (Zhang et al., 2004).

Predicting SSE recurrence

SSE intervals vary irregularly, challenging Omori-like statistical models adapted from seismicity (Utsu et al., 1995). Plate motion angular velocities provide boundary conditions but not internal fault rheology (DeMets et al., 2010). Strike-slip fault datasets show inconsistent patterns (Sylvester, 1988).
