Comments
During DART deployment 46403_20200616to20230614, the BPR detected five local earthquakes, within a few hundred kilometers of the BPR, three of which produced tsunamis that were observed at nearby coasts and two which did not. The BPR is a DART 4G, but the hardware filter that would have suppressed the seismic signal was inactive during the deployment. The Tsunami Warning Centers did not report tsunami runups for this DART for the five earthquakes mentioned earlier (Mw7.8 on 2020-07-22, Mw7.6 on 2020-10-19, Mw8.2 on 2021-07-29, Mw6.9 on 2021-08-14, and Mw6.9 on 2021-10-11). However, there was a reported tsunami runup as a result of the eruption of Hunga Tonga-Hunga Ha'apai Volcano on 2022-01-15.
