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, 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.

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).

2018-02-17, M4.4 South Wales

On the 17th February 2018 an earthquake with magnitude 4.4 occurred at 14:31:07.6 UTC at a depth of 7.4km in South Wales about 20km north of Swansea, see map below. According to the BGS  hundreds of members of the public submitted felt reports. Events of this magnitude happen in the UK only about every 2 to 3 years. The BGS reports that this is the biggest event in the area since a magnitude 5.2 earthquake in 1906.

The drumplot below shows the unfiltered seismic signal recorded on the 17th February 2017 at INSN station DSB in the Dublin mountains. The high amplitude low frequency signals between midnight and 1 a.m. are the surface waves of the M7.2 Mexico earthquake that occurred on the 16th February 2018 at 23:39:39, see https://www.insn.ie/2017-02-16-m7-2-mexico for more details on that event. The magnitude 4.4 event with epicentre in South Wales can be seen with much higher frequency content around 14:32.

2018-02-16, M7.2 Mexico

A magnitude 7.2 earthquake occurred in the Oaxaca region in southern Mexico on the 16th February 2018 at 23:39:39 UTC at a depth of about 25km. The epicentre lies onshore about 150km from the Pacific coast, see map below. About 50 homes were damaged and nearly 1 million homes were left without electricity. While no fatalaties related directly to the event have been reported two government officials died when a helicopter surveying damage crashed.

2018-02-06, M6.4 Taiwan

On 6th February, 2018, an earthquake measuring magnitude 6.4 occurred northeast of Hualien, Taiwan. So far at least seven people have been killed and more than 250 injuries have been reported. Aftershocks continue to occur in Taiwan since the earthquake.

Taiwan lies in a region of complex tectonics near the intersection of three major tectonic plates – the Philippine Sea plate to the east and southeast, the Eurasia plate to the north and west, and the Sunda plate to the southwest. The February 6th 2018 earthquake is the largest in a sequence of events in the same region over the past several days. Because of its plate boundary location, Taiwan commonly experiences moderate-to-large earthquakes.
