In Hawaii a total of 18 earthquakes have been measured under Kilauea volcano during the last 18 hours.
The largest earthquakes measured on the Big Island was a magnitude 2.2 earthquake measured on Wednesday, 6km southwest of the volcano.
Kilauea is showing increased signs of activity, as the summit lava lake remains at a high level and continues to rise.
Hawaiian Volcano Observatory spokeswoman Janet Babb said: "Overall, it's been on the high side. With this latest inflation, it's just pushing up even higher."
According to the HVO, the lava level is continuing to rise and there has been a slight increase in seismicity on the East Rift Zone near the summit area.
In Mexico the Cerro Prieto volcano is showing an increase in activity with a magnitude 2.4 earthquake measured.
The volcano is located in the Mexican state of Baja California ad the quake measured might be volcanic in original at a depth of 12km.
A volcano tectonic earthquake is an earthquake induced by the movement - either injection or withdrawal - of magma. These earthquakes do not indicate the volcano will be erupting but can occur at anytime.
Volcano ERUPTION WARNING: A number of earthquakes have been felt under volcanoes across the world
A swarm of earthquakes has been detected under the Clear Lake volcano in California - 16 have been measured during the past 21 hours at depths ranging between 4.4 and 0.2km.
Clear Lake Volcanic Field is located about 90 miles north of San Francisco and the most prominent volcanic feature is 300,000 year-old Mount Konocti.
The volcanic field has not erupted for several millennia, sporadic volcanic-type earthquakes do occur and the numerous hot springs and volcanic gas seeps at in the area point to its potential to erupt again.
Across the world, in Greece, a magnitude 2.7 earthquake was felt beneath the Nisyros volcano which may have been volcanic in its origin.
