Pre‐Sunrise Equatorial Plasma Bubble Over Indonesia During the 11 May 2024 Super Geomagnetic Storm

Earth and Space Science, Volume 12, Issue 6, June 2025.
Abstract Equatorial Plasma Bubbles (EPBs) generally form around sunset in equatorial to low‐latitude regions. However, based on observations of the rate total electron content (TEC) change index (ROTI) map over Indonesia and the ionosonde data from the Southeast Asian equatorial station during the super geomagnetic storm on 11 May 2024, we report that ...

Consequence and interaction of foaming agent components on soil conditioning of gravel-clay strata for EPB shield tunnelling

Soil conditioning of gravel-clay strata using foams for earth pressure balance (EPB) shield tunnelling is less well understood compared to conditioning for clay or sand strata. This lack of understanding can lead to muck clogging at the cutting wheel and

Observations and Modeling Investigations of Ionospheric Response to 23–24 April 2023, G4‐Class Geomagnetic Storm Over Indian Sector

Space Weather, Volume 23, Issue 6, June 2025.
Abstract This study explores the ionospheric response over the Indian sector to the G4‐class geomagnetic storm of 23–24 April 2023. Utilizing multi‐instrument observations and SAMI2 modeling, ionospheric behavior was examined during the storm's main phase (17:41 UT, 23 April–04:03 UT, April 24) and the recovery phase (04:03 UT–22:44 UT, 24 April ...

Seismic Response of Ground Penetrating Shield Tunnels Under Lateral Harmonic Excitations: Insights From Shaking Table Test

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 3, Page 867-884, March 2025.
ABSTRACT The ground penetrating shield tunnel (GPST) method offers a streamlined approach to tunnel construction in soft ground with limited open‐cut excavation. To explore the seismic response of GPST linings, a series of large‐scale shaking table tests have been conducted, including a variety of seismic excitations.

Microfacies and geochemistry of Kimmeridgian limestone strata in the Eastern Pontides (North‐East Turkey): Palaeoclimate and palaeoenvironmental influence on organic matter enrichment

The Depositional Record, Volume 11, Issue 1, Page 4-21, February 2025.
Kimmeridgian limestone (KL) strata are one best example of a peritidal carbonate that records palaeogeographic and palaeoclimate conditions in Eastern Pontide, Eastern Black Sea region. The KL strata are represented by well‐preserved dark grey lime‐mudstones that archive important geochemical proxy.
