Hawaii is one of the most volcanically active places on Earth, as effusive eruptions are continuous pretty much all of the time. Recently in Hawaii, USGS reports are keeping track of ongoing seismicity within the upper east rift zone. Geologists describe this rift zone as a growing concern. Earthquakes have been rocking the volcano reigon, including a 3.8 magnitude jolt that shook the Volcano area Thursday, February 10th at 8:30am. Kilauea in Hawaii has had ongoing activity.
Aside from Hawaii, another earthquake (4.3 magnitude) also hit the Mount St. Helens area Monday Frebruary 14th at 10:35 a.m. on the east side of Spirit Lake. However, this is not a huge concern dealing with volcanic activity, because this earthquake was of the crustal variety rather than the magmatic.
