Subduction Zone Earthquakes: Fast and Slow, Weak and Strong

by T. Parsons 13 September 202118 January 2022

What causes slow earthquakes in subduction zones? New insights from numerical models suggest that a mixture of strong and weak rocks might be the cause.

The Highs and the Lows of Megathrust Earthquakes

by T. Parsons 21 July 20212 December 2022

Why does low-frequency energy come from the shallow part of ruptures, and the high frequencies from deep?

Earthquake Rupture Solution is Up in the Air

by T. Parsons 28 May 202119 October 2021

Perhaps the most complex earthquake rupture ever studied is further constrained by signals from Earth’s ionosphere.

Was the AD 365 Mediterranean Earthquake Normal?

by T. Parsons 10 May 202114 September 2022

The great AD 365 earthquake at Crete has implied a locked Hellenic subduction zone that can produce more earthquakes to threaten Mediterranean coastlines. But what if wasn’t a subduction zone event?

Earthquake Hazard Hanging in the Balance

by T. Parsons 1 October 202011 February 2022

Earthquake hazard calculations for California’s coast are refined with a view of precariously balanced rocks that would have fallen if the largest predicted shaking happened in the past 20,000 years.

Slow Slip By Any Other Name

by T. Parsons 4 March 20202 December 2022

Earth’s faults slip most catastrophically as earthquakes. The rise of geodesy reveals an array of slower slip events, meaning faults are nearly always active. Are these behaviors really so different?
