Yes
basement rocks are more stronger than that of Deccan traps.
the velocity of deccan trap basalt is 4.8-5km/sec,but basement granite has a velocity range of 6.0-6.2km/sec.
Good question! Perhaps the Deccan Traps in India?
The Siberian Traps erupted about 251 million years ago. The traps comprised a large number of individual eruptions; each eruption of lava may have lasted between 10 and 100 years. The eruptions continued on and off for as much as 1 million years.

The last time a volcano erupted was in the 1900's in the USA.
The Deccan Traps are an area of extensive volcanic activity located in what is now India. This volcanic province was active around the end of the Mesozoic Era (Late Cretaceous Period) approximately 60-70 million years ago. The Deccan Traps were probably one of the largest volcanic complexes to occur on Earth since it's initial formation, spanning nearly half the current area of the country of India at it's peak. The timing of the Deccan Traps should ring bells in the minds of dinosaur enthusiasts: the K/T extinction that wiped out the dinosaurs occurred 65-66 million years ago, right when the Deccan Traps were active. Although it is generally accepted that a large asteroid or comet is largely responsible for this mass extinction, some question as to whether the impact had sufficient aftereffects to cause such widespread damage to the Earth's biosphere. As a consequence, some have proposed that the massive amounts of volcanic and greenhouse gases released during the eruption of the Deccan Traps also played a role in this extinction event. There is also another large volcanic complex known as the Siberian Traps of northern Russia. Unrelated to the Deccan Traps, and much older (~250 million years), the Siberian Traps have been linked to an earlier mass extinction event at the end of the Permian Period.
You can find metamorphic rocks in India along the Deccan Traps border. Igneous and sedimentary rocks can also be found there.
Answer Asteroid collision with Earth, Deccan Traps volcanic activity, or simultaneous occurence of both.

The main cause of differences in volcanic eruption characteristics is due to the viscosity of the magma. High viscosity magmas are high in sticky silica which traps gas and produces explosive eruptions. Low viscosity magmas are low in silica and produce eruptions with far less energetic characteristics.
