Reports that a magnitude 6.9 earthquake struck the Chishang, Taiwan area during the evening Saturday which caused damages to several roadways and highway sections and buildings, and interrupted rail services, but there were no reports of casualties from Saturday’s earthquake.

But a magnitude 6.4 earthquake later struck the Chishang, Taiwan area during the afternoon at 2:44 p.m. Sunday in Taiwan (11:44 p.m. PT Saturday in California) which unfortunately added more damages and caused a fatality and several injuries.

– In Yuli; a bridge collapsed, a three-story building collapsed, power infrastructure damaged leaving approximately 7,000 households without power, water pipes are damaged and a landslide on a mountain famous for the orange day lilies has trapped nearly 400 tourists.

Reports that police and firefighters rushed to the bridge collapse and three-story building collapsed to rescue and search for any survivors.

– In Chishang; a passenger train had 6 passenger cars derailed but no reports of anybody injured.

– In Taoyuan, a man was injured after the ceiling collapsed on the 5th floor of a sports center.

According to the Taiwan’s Emergency Operations Center, a cement factory worker died in Yuli by Sunday’s earthquake.

According to the Taiwan’s fire department,  146 people were injured by Sunday’s earthquake.

According to the United States Geological Survey, Sunday’s magnitude 6.9 earthquake occurred as the result of strike-slip faulting at shallow depth, near the plate boundary between the Philippine Sea and Eurasia plates at the southeast coast of Taiwan.

Preliminary focal mechanism solutions for the earthquake indicate rupture occurred on a steep fault striking either east-southeast (right-lateral), or south-southwest (left-lateral).

At the location of this earthquake, the Philippine Sea plate converges with the Eurasia plate at a velocity of approximately 73 mm/yr towards the northwest.

The location, depth and mechanism of Sunday’s earthquake are consistent with its occurrence along a fault in close proximity and relation to, the complex plate boundary in this region.

Earthquakes do not occur at points but rupture an area along a fault, and an earthquake of similar size and mechanism to the September 18, 2022 earthquake generally rupture a fault about 50 km long and 15 km wide.

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 location of Sunday’s earthquake lies south of the Ryukyu subduction zone, near the plate boundary between the Philippine Sea and Eurasia plates in this region.

The plate boundary in Taiwan itself is characterized by a zone of arc-continent collision; whereby the northern end of the Luzon (Philippines) island arc is colliding with the buoyant crust of the Eurasia continental margin offshore China.

Along Taiwan’s west coast, and continuing south, this collision zone transitions into the eastward-oriented Manila subduction zone.

According to the United States Geological Survey, Sunday’s magnitude 6.9 earthquake was preceded by an magnitude 6.5 earthquake in the same area 17 hours earlier on Saturday.

The Japan Meteorological Agency issued a tsunami advisory for several southern Japanese islands near Taiwan, but later they lifted the tsunami advisory.

Our thoughts, prayers and condolences to everybody in Taiwan following these strong earthquakes.
