Both of our #RaspberryShake seismographs (Makakilo and Pacific Tsunami Museum) recorded this evening's M6.4 #earthquake near Tonga. The depth of ~240 km / 150 mi. means it occurred within the Wadati-Benioff zone, i.e., the down-going slab beneath this volcanic arc.

Both of our #RaspberryShake seismographs (Makakilo and Pacific Tsunami Musuem) recorded this afternoon's M3.6 #earthquake near the Hāmākua Coast of Hawaiʻi Island. Like other deep earthquakes in Hawaiʻi this event likely results from the weight of the islands bending the earth's lithosphere.

AGU has filed a new lawsuit to prevent the Administration’s dismantling of U.S. scientific agencies.

We’re proud to take this stand with our plaintiffs’ coalition for our federal workforce.

Kamaʻehuakanaloa (Lōʻihi) Seamount continues to have earthquakes, such as the M3.9 event recorded this morning by our #RaspberryShake seismograph at the Pacific Tsunami Museum (tsunami.org).

Our #RaspberryShake seismograph at the Pacific Tsunami Museum recorded the M7.7 #earthquake in Myanmar nearly 11,000 km (6800 mi.) away. Being able to record such a distant earthquake indicates just how powerful it was. This power plus its shallow depth means it was likely very destructive.

Our #RaspberryShake at the Pacific Tsunami Museum recorded this morning's M3.2 #earthquake under Kīlauea #Volcano. Given its location it likely occurred at the basal detachment fault between the young volcano and old sea floor. This fault produced large earthquakes and tsunamis in 1975 and 2018.
