“…It may be possible to combine the approach of Ahmed et al () with the multisignal equivalent exposure time methods of Reimann et al () to provide robust estimates of volumetric sediment flux. There is currently ongoing research activity developing and applying sediment tracing methods in coastal settings (Liu et al, ; Liu et al, ; Liu & Sato, ; Sato et al, ; Sato et al, ; Tajima et al, ).…”

Luminescence holds unique potential as a sediment tracer and provenance method. The tracer application of luminescence has key advantages including ease of measurement, relatively low cost, and applicability to geologically ubiquitous quartz and feldspar sand and silt. These advantages can help answer fundamental questions about geomorphology, sediment transport, sediment production, and the tectonic/climatic controls on source‐to‐sink sedimentary systems. There is a notable body of research on luminescence as a sediment tracer. These tracer methods range from identifying source locations based on unique luminescence characteristics, to observing changes in luminescence characteristics with transport, to using residual luminescence to infer rates of transport. Previous applications of luminescence include provenance and quantification of fluvial transport rate, tracing of coastal longshore drift, estimations of mixing rates in soil or sediment, and provenance of wind‐blown deposits. The few studies that compare luminescence methods with nonluminescence tracer methods show good agreement. However, more work is needed to test the application of luminescence tracers in sediments. Future research directions should focus on comparing luminescence‐based with nonluminescence tracer methods. Furthermore, research is needed on the effects of specific geomorphic processes on luminescence characteristics and residual doses. While there is significant potential for future research, luminescence is already a useful sediment tracer and provenance tool applicable to a wide range of geomorphic environments.

“…This study focuses on the behavior of tsunamis occurring in Miho Bay, over the Tottori and the Shimane prefectures, Japan, located on the western coast of the Japan Sea (Figure 1(a,b)). Existing studies pointed out that Miho Bay has experienced a tsunami inundation that generated tsunami deposits on land (Sato, Nishiguchi, and Yamanaka 2015). Sato, Nishiguchi, and Yamanaka (2015) conducted a boring exploration in the bay and found a core sample that might be a deposit on land due to the 1833 Yamagata-Oki earthquake tsunami.…”

The aim of this study is to estimate how and what kinds of tsunamis are generated near shorelines in the Japan Sea, using earthquake tsunami sources proposed by the Japanese government. Tsunami propagation based on these sources was first simulated based on the linear Boussinesq theory for Miho Bay, where a historical tsunami inundated the shoreline.The results indicate that tsunami sources not only near the bay but also farther from the bay could generate significant tsunami fluctuations. Thus, the amplification of the latter tsunamis was examined using Fourier analysis. Tsunami waveforms in the bay periodically fluctuate with large amplitudes after the first wave. The Fourier analysis specified these periods to be 13-16 min, consistent with the estimated resonance periods of the bay. Therefore, it can be concluded that one of the factors responsible for the amplification of tsunamis in Miho Bay is the bay-scale resonance. To investigate why resonance occurs during tsunamis, a relationship between the tsunami source geometry and the generated tsunami was examined. This analysis indicates that specific tsunami sources located in critical areas could enhance the resonance in Miho Bay. ARTICLE HISTORY
