The amplitude of the final source model is consistent with the predictions obtained from published empirical equations. Delhi experienced four small earthquakes during April - August 2020, with the first event of magnitude 3.5 on April 12 in the northeastern boundary of Delhi. Note: Because of minimal operations during the holidays and upcoming Western new year, there won’t be any preview releases for the month of December 2018. Our best source model involves potential energy of 7.14 × 10 13–1.05 × 10 14 J equivalent to an earthquake of magnitude 6.0–6.1.

Based on the qualities of spectral and amplitude fits between observations and simulations, we constrained the tsunami source dimension and initial amplitude in the ranges of 1.5–2.5 km and 100–150 m, respectively. Twelve source models were numerically modelled with source dimensions of 1.5–4 km and initial tsunami amplitudes of 10–200 m. We identified initial tsunami period of 6.3–8.9 min through Wavelet analysis, leading to an initial tsunami dimension of 1.8–7.4 km. For the most up-to-date information, please visit the USGS event page, and for estimates of casualties and damage, visit the USGS Prompt Assessment of Global Earthquakes for Response (PAGER) website. Physical modeling of a volcano flank collapse showed that the initial tsunami wave mostly involves a pure-elevation wave. A magnitude 7.0 earthquake struck north of Anchorage, Alaska, on November 30, 2018, at 8:29 a.m.
Here, we apply a combination of qualitative physical modeling and wavelet analyses of the tsunami as well as numerical modeling to propose a source model.

Since the occurrence of this rare tsunami, it has been a challenge as how to model this tsunami and to reconstruct the network of coastal observations. The eruption of the Anak Krakatoa volcano (Indonesia) in December 2018 produced a destructive tsunami with maximum runup of 13 m killing 437 people.
