Seismic magnitude scales

Two earthquakes of magnitude 4 and 4.1 were recorded in a short time (just two minutes apart) in the sea area off Crete.

The first earthquake (time 10:22) had a magnitude of 4 Richter, a focal depth of 10 kilometers and an epicenter 32 kilometers southeast of Heraklion’s Mamia.

It had a magnitude of 1.7 on the Richter scale.
The earthquake happened tonight at 1:17 p.m.
It was at a depth of 9 kilometers.

In the wake of 4.2 magnitude earthquake in Nafpaktos, seismologist Gerasimos Papadopoulos has stressed the need for preparation and vigilance noting that the Corinthian Gulf can "give" large earthquakes.

The European Mediterranean Seismological Center (EMSC) registered three earthquakes in Bulgaria within 30 minutes.

The first, at 10:15 am, was the strongest - with a magnitude of 3.5 on the Richter scale. Its epicenter is 13 km north-northeast of Dimitrovgrad and 30 km from Stara Zagora. Its depth is 2 km.

In the past two months, Greece has seen an increase in seismic activity, with moderately strong earthquakes that do not exceed a Richter scale threshold of five degrees.

Indicatively, three locations, Lesvos, the sea area north of Crete, and Evia, have experienced an increase in seismic activity, but this coincidence is not thought to be related to usual geodynamic processes.

At 03:53, the National Seismological Network registered an earthquake in the Belgrade region with a magnitude of 2.1 on the Richter scale, and it could be felt in some parts of the city as a slight tremor, especially in high-rise buildings.

According to her, it is difficult to say where these earthquakes will happen, but as she says, there are areas in Macedonia, Bulgaria, Romania, and even in eastern Serbia where there were no earthquakes for many years.

Seismologists reported two moderate quakes on Wednesday, though there were no reports of any injuries or damage.
The first temblor, measuring 4.1 on the Richter scale, struck the seabed off the island of Kastellorizo at 8.20 a.m., according to the National Observatory of Athens' Geodynamic Institute.

An undersea earthquake, measuring 4.3 on the Richter scale, rattled Greece's southern Aegean island of Karpathos on Wednesday, but there were no initial reports of damage or injuries.

According to the National Observatory's Geodynamic Institute, the quake's epicenter was located 81 kilometers southeast of Karpathos.

A 5.6 magnitude earthquake on the Richter scale has struck southern Iran. Preliminary reports indicate that the outbreak of the earthquake is at a depth of 2 km in the province of Hormozgan, near the town of Bandar-e Lenge.
