2020-01-24, M6.7, Turkey

At 17:55:14 UTC on January 24th, 2020 a magnitude M6.7 earthquake struck the Kalaba-Sivrice region in Eastern Turkey, see the map below for the approximate location of the event. The earthquake had a depth between 10 and 15 km and resulted in very strong to severe ground shaking. Currently 22 fatalities and hundreds of injuries have been reported with the collapse of several buildings. The earthquake is located on or close to the East Anatolian Fault which separates the Anatolia Block of the Eurasia plate from the Arabia plate. Damaging earthquakes occurr relatively frequently in Turkey. According to the USGS seven other M6 or larger events have occurred over the preceding half century within 250 km of the January 24, 2020 earthquake. For maps showing plate boundaries and locations of past earthquakes in Turkey see https://en.wikipedia.org/wiki/List_of_earthquakes_in_Turkey.

The earthquake was recorded at seismic stations worldwide, including stations of the Irish National Seismic Network (INSN), see seismic waveforms below (select figure to enlarge).

2019-12-20, M1.4, Irish Sea

On the 20th of December 2019 at 09:53:44 local time, a M1.4 earthquake occurred in the Irish Sea approximately 90km north-east of Dublin and 40km south of the Isle of Man. The epicentre location is shown in the map below. This event follows a M2.5 earthquake in the Irish Sea from the 15th of December 2019. The M1.4 earthquake is most likely an aftershock of the recent M2.5 earthquake.

The event was recorded by the Irish National Seismic Network (INSN) and British Geological Survey (BGS) seismometers, and can be seen in the waveforms plotted below:

2019-12-18, M1.6, Offshore Antrim

On the 18th of December 2019 at 20:22:14 UTC, a M1.6 earthquake occurred offshore Co. Antrim, Northern Ireland. The earthquake located approximately 10km east of both Ballycastle and Rathlin Island, and at a depth of 1km. Since 2010, the Irish National Seismic Network (INSN) has previously recorded 5 earthquakes off the Antrim Coast, the largest of which was an M1.6 earthquake occurring on the 26th of October 2013.

The event was recorded by the Irish National Seismic Network (INSN) and British Geological Survey (BGS) seismometers, and can be seen in the waveforms plotted below:

The INSN is operated by the Dublin Institute for Advanced Studies (DIAS) in co-operation with the Geological Survey Ireland (GSI).

2019-12-15, M2.5, Irish Sea

On the 15th of December 2019 at 21:19:52 local time, a M2.5 earthquake occurred in the Irish Sea approximately 90km north-east of Dublin and 40km south of the Isle of Man. The epicentre location is shown in the map below. Events of this nature are not uncommon in the Irish Sea, a similar smaller event occurred on the 17th of November 2019. There has also been a subsequent M1.7 event at 06:23:55 on the 16th December off the English coast North of Blackpool (see map at bottom of page).

Location of M2.5 event on the 15th December 2019.

There have been no reports that the earthquake was felt onshore but the event was recorded by the Irish National Seismic Network (INSN) seismometers, and can be seen in the waveforms plotted below.

The INSN is operated by the Dublin Institute for Advanced Studies (DIAS) in co-operation with the Geological Survey Ireland (GSI).

2019-11-26, M6.4, Albania

At 02:54:11.3 UTC on November 26th, 2019 a magnitude M6.4 earthquake struck a region to the North-West of Tirana in Albania. The earthquake had a depth of 10km which resulted in very strong to severe ground shaking. Several fatalities and hundreds of injuries have been reported with the collapse of several buildings. The map below shows the approximate location of the event.

Large earthquakes are common in this region due to the convergence of the African and Eurasian plates. The region has suffered seven >M6 events within 150km of the recent event in the past 100 years. The earthquake was recorded at seismic stations worldwide, including stations of the Irish National Seismic Network (INSN), see seismic waveforms below (select figure to enlarge).

2019-11-17, M1.2, Irish Sea

On the 17th of November 2019 at 14:56:08 local time a M1.2 earthquake occurred in the Irish Sea approximately 50km north-east of Dublin. The epicentre location is shown in the map below.

The event was too weak to be felt but was recorded by the Irish National Seismic Network (INSN) seismometers, and can be seen in the waveforms plotted below (most obviously on the eastern stations of Dublin, Louth and Wexford).

The INSN is operated by the Dublin Institute for Advanced Studies (DIAS) in co-operation with the Geological Survey Ireland (GSI).

2019-09-24, M5.6, Pakistan

On September 24, 2019 at 16:01 local time a magnitude 5.6 earthquake occurred close to New Mirpir in Pakistan-administered Kashmir. At least 20 people were killed and hundreds injured. The region is prone to earthquakes due to the convergence of the Eurasian and Indian tectonic plates.

2019-05-26, M8.0, Peru

On the 26th May 2019 at 02.41 local time (07:41:14 UTC) an M8.0 earthquake occurred in Northern Peru, 75km SSE of Lagunas. The earthquake occurred at a depth of 110 km. At least one person has been killed and several injured. The region is prone to large earthquakes due to the nearby oceanic Nazca plate subducting beneath the continental  South American plate.

The earthquake was recorded at seismic stations worldwide, including stations of the Irish National Seismic Network (INSN), see seismic waveforms below (select figure to enlarge).

2019-02-22, M7.5, Ecuador

An earthquake of magnitude 7.5 occurred in the Peru-Ecuador border region, on the 22nd February 2019 at 05:17:23.0 local time (10:17:23.0 UTC). The quake was centered about 116 km SE of Palora, Ecuador and 275 km SE of Quito, Ecuador. According to the US Geological Survey (USGS) the earthquake, which had a depth of 125 km, is not expected to cause major fatalities or damage.

 

The earthquake was recorded at seismic stations worldwide, including stations of the Irish National Seismic Network (INSN), see seismic waveforms below (select figure to enlarge).

2018-02-25, M7.5 Papua New Guinea

On 25th February, 2018, an earthquake measuring magnitude 7.5 occurred at 4a.m local time, in a rural, jungle area of the Southern Highlands in New Guinea, Papaua New Guinea. It wasn’t immediately clear if there was damage. No tsunami watches or warnings were issued because of the quake.

At the location of this earthquake, the Australia plate is converging with the Pacific plate and it occurred as the result of thrust faulting at shallow a depth. Thrust-faulting events of the size of the February 25th, 2018 earthquake are typically about 85×30 km (length x width).
