🌟OPEN ACCESS🌟The Role of “Equation Error” in Empirical Regressions for Seismic Magnitude Conversions #BSSA ⚒️

What’s the best way to convert between traditional magnitude and moment magnitude?

pubs.geoscienceworld.org/ssa/bssa/art...

New simulations of earthquake cycles on geometrically rough faults show an interplay between slow sip, creep and foreshocks leading to rupture of the entire fault. #BSSA⚒️

Fig. 4 from the paper. Top left: epicenter locations from August 20, 2021 to February 6, 2022 in the NLL-SC catalog. Events are color-coded by hypocenter depth and sized with respect to their magnitude. The blue circle marks the mainshock of August 14, 2021 (M 7.2) from Calais et al. (2022), shifted in location on the map to avoid cluttering the aftershock distribution. The black boxes delimit zones 1, 2, and 3, separately described in the text. Black lines show the main active faults as in Calais et al. (2023): EPGF, Enriquillo Plantain Garden Fault; RF, Ravine du sud Fault; JMF, Jérémie-Malpasse Fault, as well some cities: J, Jérémie; A, Anse-à-Veau; M, Miragoâne. Bottom left and top right: hypocenter depths projected along east–west and north-south cross-sections. Bottom right: histogram of hypocenter depth with 2 km interval bins.

Fig. 12 in the paper. Interpretative synthetic cross-section of the study area. Earthquake hypocenters, plotted with white dots, are actual hypocenters from sections 6 and 14 on Fig. 5. Main faults inferred are shown with solid black lines. The fault segments involved in the 2021 Nippes earthquake sequence described in this paper are highlighted with a dashed red line. The yellow star indicates the nucleation location of the M 7.2 Nippes earthquake from Calais et al. (2022).

‪🤑OPEN ACCESS🤑 In a new paper, lead by Sylvert Paul, we precisely relocate the 2021 M 7.2 Nippes, Haiti, earthquake sequence using broadband and low-cost, citizen-hosted, seismometers.
Strain is partitioned on strike-slip, reverse, and obliquely-slipping faults.

M6.8 earthquake offshore Japan preceded by upward cascade of foreshocks What do we know about seismic hazard in the Japan-Kuril subduction zone?

⚒️ 🧪

A M6.8 earthquake struck offshore Japan today - another large earthquake from the subduction zone that produced two recent great earthquakes. The earthquake was preceded by a "cascade up": foreshocks progressively increasing in maximum magnitude.

What do we know? What might happen next?

This visualization of Japan’s M6.8 yesterday is phenomenal. Offshore S-net detected it and issued earthquake alert before any land station detection. Numbered circles show JMA intensity (not same as MMI). Offshore is where we need to be in Cascadia as well.

Role of Fluid on Earthquake Occurrence: Example of the 2019 Ridgecrest and the 1997, 2009 and 2016 Central Apennines Sequences - Pure and Applied Geophysics This paper focuses on the study of the temporal evolution of seismicity and the role of fluids during major earthquake sequences that occurred in the Central Apennines and Southern Walker Lane belt-Ea...

📢 Paper Alert!
Excited to share my new paper in Pure and Applied Geophysics: “Role of Fluid on Earthquake Occurrence”.
We show how fluids -b-value drops help shape foreshocks & aftershocks in Ridgecrest (2019) & Central Apennines (1997, 2009, 2016).

An aerial view of Gaza City taken from a Jordanian military aircraft by photojournalist Heidi Levine in July 2025. Massive destruction is visible, as are IDP tents.

An aerial photo taken from a drone photographer in 2019 showing Gaza City's Old Town facing east, providing a view similar to the aerial photo taken in July 2025.

For another comparison, there's also an aerial view from a similar perspective, though at lower altitude since it's from a drone photographer, here on Facebook from 2019: www.facebook.com/photo/?fbid=...

The drone photo is closer to 31.5057, 34.4619 whereas the plane photo is closer to the coast.
