Members of Greece's military geographical team conduct geological measurements, to evaluate potential structural changes due to the ongoing seismic activity on the volcanic island of Nea Kameni, Greece,

Based on the available data, this activity is due to a combination of tectonics and deeper magmatism, scientists said

The Greek island of Santorini was struck by the latest in a string of earthquakes Tuesday, this time a 4.8 temblor. The government said it will backstop the island destination's tourist industry.

The swarm near Santorini appears to be related to the activation of a system of normal faults, fractures in the Earth’s crust where there is movement. Earthquakes are the result of a sudden release of tension built up by the movement along these faults.

Usually teeming with tourists, incessant earthquakes have seen the Greek island of Santorini deserted by the majority of its residents

A new cof magnitude 5 on the Richter scale was recorded on Tuesday morning between the Greek islands of Santorini and Amorgos. The earthquake occurred at 4.46 a.m. local time (0246GMT) at a depth of 13 kilometers (8.077 miles), according to the Geodynamics Institute of the National Observatory of Athens.

Santorini is a jewel in the Aegean Sea. The stunning sunsets, white-washed buildings, and crystal-clear waters are world-renowned. However, a series of earthquake tremors have shaken the island, raising concerns about the safety of visiting this popular tourist spot.
