Mauna Loa Quake Activity Increases

 US,MX
During the past couple weeks, Mauna Loa, Hawaii's largest and historically most active volcano, has been exhibiting more quake activity at its summit, and SW rift zone. HVO is monitoring the situation. Inflation restarted in the volcano in 2010, and a slow but gradual inflation is taking place. This is a bit unusual, as Kilauea is still pumping plenty of lava out and consistently creating new land. Typically, Mauna Loa only inflates when Kilauea is not active. It would be highly unusual, [...]

From CNNFrom WikiFirst of all, where is and what is Vanuatu? It's an island nation of volcanic origin in the South Pacific some 1000 miles east of northern Australia. If you subscribe to the USGS earthquake notification system, you'll see a lot of alerts about earthquakes near Vanuatu. 65 of Vanuatu's 82 islands are inhabited. The islands are steep, prone to landslides and slippages, and there is little permanent fresh water. The shorelines are rocky and drop quickly into oceanic depths because [...]

Villarica eruption March 3, 2015.AP Photo/Aton ChileVillarrica volcano is one of Chile's most active volcanoes. It lies along the crest of the Andes in southern Chile, at the west end of three stratovolcanoes that trend perpendicular to the Andes along a fault. The lava is basaltic-andesite and the eruptions are typical Strombolian eruptions that eject pyroclasts several kilometers into the air and lava flows. In 1964 and 1971 massive lahars accompanied the eruptions because of rainfall and [...]

A nice quake swarm is occurring just South of Lassen Volcanic Center in California, US. The largest quake so far in the series has been a 3.9, and at this time the swarm is ongoing. So far around 35 quakes have occurred in the area over magnitude 1. It is unclear at this time whether the quakes are tectonic or volcanic in nature, however the fact that most are quite shallow could indicate this is merely a tectonic or hydrothermal event. Time will tell.Quake swarm south of Lassen. Screenshot [...]
