Why the Mw 6 Earthquake near Java Generated Strong Shaking

The magnitude-6 earthquake that struck Java on Saturday, 10 April 2021, at approximately 2pm (local time) occurred at a depth of 82 kilometres (km), according to the United States Geological Survey. This earthquake was strongly felt in East Java and led to loss of life and property. The location of this earthquake is the main reason why it was felt so strongly.

What Caused the Strong Shaking of the Japan Mw 7.1 Earthquake

A Mw 7.1 earthquake struck Japan on 13 February 2021 at approximately 11:07pm (Japan local time). According to the United States Geological Survey, the earthquake occurred at a depth of about 50 kilometres (km) and about 70 km from the town of Namie, off the east coast of Honshu. The event was widely felt, injuring more than a hundred people and damaging some infrastructure.

How a Volcano Influenced Earthquakes in Lombok, Indonesia

A series of deadly earthquakes struck the Indonesian island of Lombok over three weeks in August 2018, causing widespread damage. These earthquakes were unusual because there were two magnitude-6.9 mainshock events that were each preceded by a smaller foreshock, instead of a single mainshock. The complexity of the earthquake sequence caused great anxiety about when another powerful earthquake might occur.

Using Large Earthquakes to Understand Singapore’s Underground Structure

The first results from Singapore’s first island-wide seismic survey unravel some important features of Singapore’s underground.

In March of last year, a team at the Earth Observatory of Singapore (EOS) recorded the ground movements of Singapore using 88 seismometers placed in locations such as schools, parks and weather stations.

Powerful Twin Quakes Strike Southern California

On 5 July 2019 at 1.33am (Singapore time), a Mw 6.4 earthquake struck the town of Ridgecrest in California. Its seismic waves could be felt from Los Angeles to San Jose. Nearly a day and a half later, on 6 July at 11.19am (Singapore time), a more powerful Mw 7.1 quake struck the same region. Because the Mw 7.1 earthquake is the largest event so far in this sequence, it is considered to be the mainshock. The events leading up to it, which include the Mw 6.4 quake, are considered to be foreshocks.
